It's really impressive. Detailed work and craftsmanship. I learned a lot from your work. Never imagined a violin bridge can be so beautiful like this. Thank you very much.
Mille grazie. Wonderful insights - thickness/distance measurement with the calipers, measuring the string action, marking the bridge curvature by measuring off the finger board. Much appreciated.

Un trabajo tan meticuloso,la talla hermosa que le dió,me quede con las ganas de la prueba de sonido,pero es un gran y hermoso trabajo,felicidades un saludó grande.
Hace un par de meses el puente de mi violín se estropeó y no tengo confianza para llevarlo con ningún Luthier de este lado del mundo :/, así que procedí a hacerlo basandome en varios videos, este en particular me ayudó bastante para hacerlo, claro, de forma amateur y con herramienta casera, gracias!
The most important thing to avoid damaging your violin is the good fit of the feet to the arching's curve and the bridge's structural strength. Of course, for the sound and aesthetics, going to a good luthier would have been better, but I'm happy to know that my video helped you make your violin playable again.🙂
I literally just finished making my first bridge out of Australian bottle brush that I had left over from pruning. It's a harder timber but gives a bright, crisp sound.
The bridge has a decisive influence on the sound and in particular on high frequencies, maple is the most used and most tested wood, especially for a sound linked to classical music, but this does not mean that other types of wood cannot give results equally interesting. Experimentation is always the key, the ideal would be to make a traditional bridge in maple and others with different woods, so as to be able to compare the results on the same violin
@@DavideSora I do plan on doing this but I do talk to a guitar luthier regularly about this sort of thing. The interesting thing is that many classical guitar players consider instruments made from Australian timbers to project and give instruments unique tonal qualities, among these of course is Anna Vodovic and I often wonder why these species haven't made it into bowed strings as far as classical repertoire. I plan on making some more bottle brush bridges and some mulberry, I certainly prefer my bottle brush bridge over my violin's maple bridge.
@@jonathonaltmann4493 I have always encouraged the use of local woods, European maple is the most used because it has been tested for centuries, but when this experimentation began, Australian woods were certainly not available here in Europe, so who knows what would have happened if they had been available to the luthiers of the sixteenth, seventeenth and eighteenth centuries🙂

Yes, if the bridge is not in the right position the relationship with the soundpost is no longer adequate, and even with small changes in this distance, the sound can suffer a lot. However, some older violins have the bridge intentionally placed in a different position with respect to the F inside notches, usually to compensate for too long a vibrating string, so the soundpost could be placed accordingly. Moral: Always check the bridge/soundpost relationship after moving the bridge. But if the sound of your violin has improved after bringing the bridge back to the correct position, it is a clear symptom that there is no problem with the soundpost. To get an idea of the correct soundpost position you can watch this video: ruclips.net/user/shortsALodkm5uF8s keeping in mind that each violin will need a slightly different position based on its acoustic response and construction characteristics
Im curious how one knows if arms, legs and the heart of the bridge can be made even thinner so there is even less loss of energy from strings to top plate. I wonder if there were any physicists (or amateur experiments) who made public studies in whats the most efficient shape in relation to wood density before bridge will become too weak.
The dimensions of the various sections of the bridge can (and should) be optimized according to the response of the violin. There are many scientific studies on these aspects of bridge, but no one can give precise recipes because, in addition to the properties of the wood, the results are variable based on the characteristics of the violins, which are never the same. So the best system remains that of try and error, starting with a stiffer bridge with wider sections and modifying it little by little according to the acoustic response of the violin to which you are adapting it. It is a process that requires experience and often requires adapting more than one bridge to get the one that works best on that particular violin and for that player, because the sound has a component linked to personal taste that remains essential. If you are interested in scientific studies you can start with these which are available on the web for free: hrcak.srce.hr/file/346888 oosterhofonline.net/pdf/Bridge_wood_removal_Rodgers.pdf vsapapers.org/index.php/journal/article/view/4/13 You can find many others by searching the various scientific publication sites by paying modest amounts of money, such as this: iopscience.iop.org/article/10.1143/JJAP.41.6291/pdf
@@johngeddes7894 Thank you. After experimenting with carving bridges to as thin as possible. I understand now why people don't do it. If one removes too much mass, the dynamics range will decrease. So pianissimo becomes louder but fortissimo stays the same. It's harder to play quiet and control dynamics. For the sound it is similar as if one would use "Compressor effect" digitally. Thus certain amount of resistance (more mass) is desired in bridges.
Rocking frequency, material properties, and weight can give a clue ( ruclips.net/video/9P8n46DOaDg/видео.html ), but it basically depends on the sound of the violin the bridge was made for. The best thing would be to keep it slightly oversized, try the violin, and make changes to the bridge according to the result and expectations of the player/owner. Of course, experience is needed to know how and where to intervene, and it can often be useful to cut more than one bridge to obtain the desired results, so as to be able to evaluate the acoustic effect of different bridges on the same violin. It is not something feasible for a factory or low-cost violin, but for fine violins it is the most sensible thing.
@@DavideSora Thank you Davide. By the way, have you seen Kevinleeluthier saying the bridge side of the tailpiece should be a little less than 90 degrees? I guess this is how Paganini had his violin set up?
@@TNungesser I don't know Mr. Lee personally and I don't want to criticize him, but I often find myself disagreeing with what he says, I may agree with some things but others just don't make any sense to me, bordering on misinformation. 😐 As for the bridge, tilting it back (toward the tailpiece) to bring the rear face into the bisector of the string angle might sound sensible, but it's actually a great prerequisite for seeing it bent back in a short time. I think that at most it is the front face that must be on this bisector, but in reality it is a theoretical condition that is difficult to obtain or even just to verify in practice, also seeing that each string has a slightly different angle on the bridge and that the angle of the neck, the height of the bridge and the height of the saddle can vary instrument by instrument modifying the general set-up. In my experience, bridges made as you see in my video don't bend in any way when properly made and maintained, and another thing I've noticed is that leaning the bridge backward (towards the tailpiece) can cause problems when playing with the bow very close to the bridge ("sul ponticello"). So to me it's a "no-no", and I don't think Paganini's bridge was angled that way. Together with the violin the original bridge and fittings that he used are preserved, and observing how the feet are cut it seems that it was with a normal inclination (rear face vertical) even if it is difficult to understand this with certainty due to wear. It is also quite different from modern bridges, it can be classified as a transitional bridge between the baroque shape and the modern shape (it has no heart and has very small feet). Where does your guess come from?
@@TNungesser. You make one, fit it, play it , think about it……then you make another and repeat the process. Then you make a third…..and then you decide.
On a dark sounding, bassy violin this is done, most often on a Guarneri del Gesu model violin. It helps to give a little more bite and clarity to the violin that needs it. I wouldn’t do it on a bright sounding violin.

(Sorry if I answer in English, but in this way others will be able to read my answer. However I don't speak Spanish and I should have trusted the google translator to write the answer, and I don't know if it does a good job...) First of all, this video is only a condensed version, you will probably find many of the answers to your questions in the detailed series of all videos on the bridge, which I have collected in this playlist: ruclips.net/p/PLaxadm6POX7EjpjW2BpAr1d_U8ITO5GFP For example, in this video of the series you will find the indicative measures: ruclips.net/video/9P8n46DOaDg/видео.html However, there are no fixed measurements, but each violin will need slightly different measurements to adapt the bridge to its construction geometry and sound response. The finish of the various elements (heart, kidneys, legs, etc.) mainly has an acoustic value, the aesthetic is only a consequence. By changing these cutouts you can adjust the response of the violin, especially in the high frequencies range. The wood to remove compared to the initial bridge blanks is a lot, to give you an idea its weight is reduced to almost half of the initial weight, but this obviously depends on how your bridge blanks are made, not all of them have the same raw dimensions when you buy them. However none of the surfaces of the bridge blank will remain intact, all will be trimmed to some extent. The thickness of the plates doesn't have much to do with the bridge, at least not directly. The sound of the violin will dictate how to make the bridge, and also geometric aspects such as the inclination of the fingerboard for the height and the position of the bassbar and the distance between the upper eyes of the Fs which will be considered to determine the width of the feet. Making a good bridge that works well and lasts over time requires a lot of knowledge of the aspects involved, which are many, which is why the ideal would be to entrust the job to an expert professional violin maker.
I'm on my third carved bridge and I can already say that I know how to carve. The third being the best bridge ever created Aubert De Luxe. What I have noticed with some sculptors, they are very wrong about the thickness of the bridge, taking too much of it they lose the power of the instrument, the more thickness you take, the less the sound transmitted to the violin is, and as much as possible must be sent to the instrument for a developed sound, therefore a balance must be found between the clarity given by a thin bridge in thickness and the force given by a less thin bridge, of course the most is taken in the head of the bridge, but as you go down you still need a thicker bigger than what most do. This is a finding of mine considering that I sing on a fairly old instrument with an extraordinary resonance, which after I put the Aubert De Luxe bridge on it in the style I described above, there was simply an explosion of extraordinary sounds. How much quality and attention matter. I'm wrong ? correct me if I'm wrong sir.
I would say that the concept you express cannot be considered wrong. Still, rather than talking of thickness alone, it would be more correct to speak in terms of mass and stiffness, which are clearly connected to the thickness, but not only: the properties of the wood and the heights (dimensions) of the various sections (arch, legs, ankles, waist) are an integral part of the picture in determining mass and stiffness. However, a bridge that is too thin in the lower part could indeed cause a slightly thin tone, but it remains to be established what we mean by too thin or too thick, these are rather abstract terms if not quantified.🙂
@@DavideSora😁♥️🙏 Absolutely perfectly, sir, you mentioned the other properties that need attention. Many congratulations, I respect you from Romania 🙏.
Good video. I have a moderately priced violin that has a superb tone. It is a nice hand crafted violin, but needs a better bridge and a new nut. The nut was cut with narrow string spacing of under 15mm, the original owner had very small hands. Someone tried to fix it by filling the string slots and recutting the grooves. It’s a mess. I’m going to cut a new nut and bridge.
To change the string spacing at the nut, making a new one is the way to go. If the bridge is in good condition and the strings are a little high on the fingerboard, it is possible to change the spacing by lowering it without making a new one. But considering that modifying or changing the bridge could affect the tone, the situation should be evaluated carefully.
@@DavideSora the shop I took it to originally said they dint want to remove the nut, so they filled the grooves and recut the slots. It was not done well. They said they didn’t want to remove the nut. I used one of my carving knives and it popped off after the second try. I’m shaping the new nut. I cleaned and squared the area where the nut sits.
@@bremms1 It is possible to fill the string notches with cyanoacrylate glue and cut them in the correct position, but this is only a cheap solution that does not work very well, it may be acceptable only as an emergency repair if there is no time to make a new nut. As you may have noticed, removing the old nut is not difficult at all, and making a new one is not that complicated. However, it depends on the value of the violin and the hourly rate of the person doing the work, because it is a job that requires precision and a few hours of work. You can see how I make the nut here: ruclips.net/video/p0zvd5Uic5A/видео.html
Thank you, yes that was what I was thinking. This violin is worth $12-1500 dollars so I understand why they did that. I’ll look at your video before I finish the nut. I have some nice planes, files and chisels. My carving blade is a flat bar of hardened tool steel. I made a handle for it, but prefer it without. You have been very helpful.
great videos of you..i enjoy to watch every each of them.Is in any chance possible to get the measures of that tool to measure the right string position and spacing? thanks a lot.
Do you mean the wooden one in the shape of an elongated trapezoid, which you see here? ruclips.net/video/wEwWvDbc2Og/видео.htmlsi=NURFD4ZDl25zRqDZ&t=554?
@@passionisart Well, not a very high-tech tool🙂, but it works like a charm and is extremely accurate. It is made from a 2mm thick willow violin lining scrap, approximately 70mm long, 15.7mm and 9.7mm wide. The horizontal lines should be drawn with a square when it is still rectangular, then adding the same taper on both sides. The horizontal pencil lines are drawn almost randomly, about 1.5 mm apart. The three widest ones at the top are for viola, the widest is about 12.2 mm and the narrowest is 12 mm wide. The others are for violin, the thickest one is my average reference and measures 10.9 mm in the center of the thick line. The purpose of this tool is not to set a measurement, but to check that there is an equal spacing between the strings. A divider is used to set the total spacing and the spacing between each string. This spacing can be varied according to the violinist's preferences, my reference measurement (the thick pencil line) is just for when I do not have particular indications from the violinist, so I set a not-too-wide or not-too-narrow spacing that should work for most violinists
@@DavideSora grazie Davide :) i watched all of your videos and the material is very good.i am carving my bridges under your specs and they sound very good :)..thanks for all help here :)
I just put my first bridge on. Question: When you are finished and have it in place and the violin doesn't sound like you want it to , is it then you realize you took off to much or you need to reshape it more and in what area.? I tried to match the one that I replaced. I do think I can do better next time and may geta dozen of them and work on it, But what I'm not sure of is on what part of the bridge is vital to making sure the sound is functional.
Simplifying to the extreme, the most sensitive area is the waist, but the distribution of masses and geometry introduce many variables. A bad fit of the feet is the first thing that could compromise the sound. In short, it is too complex to put it in a post on RUclips, many articles have been written on this topic that could be useful for you to get an idea. For example this one here: fiddlerman.com/wp-content/forum-media-uploads/elcb/2021/04/Bridge_wood_removal_Rodgers.pdf or this other one here: www.mdpi.com/1424-8220/13/11/15290 You will find many other interesting articles on the violin bridge in the references paragraph of these two articles. Lot of pages to study, I did. Unfortunately, experience and many bridges for many violins play a decisive role in obtaining the necessary sensitivity. Bridge and set-up are the hardest parts to learn in violin-making.
@@DavideSora Thanks... I got everything I need to shape the piece of wood. I certainly got some reading to do. After I read all of this maybe my question as to Why don't they already come (Other than than the feet ) ready to go? Seems to me they are leaving it up to you to reach a sound that you prefer. Taking wood off here and there seems to be arbitrary. I see you measuring. Is it the same for each bridge? or do you just hope? It's an ole fiddle I got ...I put new pegs on it, new bridge, strings, sound post is perfect...sounds better than it did... but just wondering if I can make it sound better..it maybe all she can give...again thanks for your input.
@@DavideSora This is from what you sent me.... Consequently, a maker trimming a bridge does not have to be concerned that his work will change the nature of the bridge as a vibrating system. Thus, the options now used by violin makers appear to make substantial reductions possible in all three bridge frequencies and offer ways to reduce frequencies selectively. It is no wonder that the advice received from makers was difficult to understand.
@@fordjubilee In this video ( ruclips.net/video/9P8n46DOaDg/видео.html ) I indicate two sets of measurements, which indicate the minimum and maximum of my preference. Consequently, you can deduce that I don't always use the same measurements, because there is a need to adapt them to the properties of the material (as usual, two pieces of wood, and this also applies to bridge blanks, will never be the same), and to the sound we like, what is best is not the same for all of us. Then, it seems to me that some can never be satisfied with what they obtain, thinking that something can always be improved simply by modifying the bridge or the position of the soundpost, when often the limit is the violin we have. In fact things can be changed, but not always for the better, or simply obtaining different but equally acceptable sounds depending on taste. Given that you say your violin is much improved, I would not modify the current bridge but make others with different characteristics (measures, type of wood, etc.) and replace them one after the other to see what happens to the sound. In this way, you will be able to choose the bridge that gives you the best results, and if this is not the case you will always be able to restore the initial conditions and be satisfied with the improvements obtained with the first bridge. a lot of work, but very informative to gain experience. You can also modify the bridge step by step without removing the strings to eliminate the inevitable variables that this would entail, listening to what happens to the sound after each small change in the measures. This is also very informative but only from a learning perspective: at the end of the process, the bridge will be destroyed and unusable, so you will have to build another one, trying to put into practice what you have learned. It will probably be like starting from scratch because the memory of sound lasts very little (scientific fact), but you can understand which parts are most sensitive to changes, which is no small feat.
For the knives I only purchase the raw blades. The wooden handles, and of course the shape and sharpening of the cutting edge are made by me. The blades come from different manufacturers, a couple are John Schmidt's PM-X steel, one is an old Pfeil and one is made from an old circular saw blade. In any case, any good quality blade will serve the purpose well, if shaped and sharpened correctly, which remains the most difficult undertaking
Red chalk. A simple blackboard chalk, crushed and pulverized. You have to make sure it is the dry type, without any additives like waxes or fats to make it softer as some artist chalks have. You can see it in more detail in this video: ruclips.net/video/jA5_5GiQm-Q/видео.html

Hello. How do you know that a bridge of a good quality of wood? I got some from a local shop. They seemed to be OK but turned to be soft maple wood. All of my installed bridges went bent a lottile in a year or two.
Understanding if the wood is of good quality is a matter of experience, but it is possible to get an idea by observing the compactness of the grain and, above all, the direction and sharpness of the medullary rays, which must be long and continuous by observing the bridge from the side and as narrow and sharp as possible by observing the bridge on the faces. This would most likely indicate a hard and stiff wood, although sometimes a softer wood may be needed for example in the case of violins that are too harsh in the high frequencies. As for the bridge bending, the cause is often an incorrect inclination of the bridge with respect to the vertical. In fact, with the tuning, the strings will tend to pull the bridge forward, which, if it is not brought back to the correct position, will inexorably bend in a short time. A properly cut bridge held in the correct position (tailpiece side perpendicular to the line of the ribs, i.e. to the gluing line of the top plate) can last many decades before starting to bend.

@@DavideSora Thank you very much for this explanation ! Also, would it be inadequate of me to ask who is your bridge provider ?

Your jigs are really great too and inspiring, thank you again for sharing your knowledge !
Are there instructions as to Why to carve the bridge the way you do? I understand why one would carve the feet to fit to the top of the violin. But why make the bridge a very specific thickness and how think? Why carve the kidneys and how to know how much to carve? And the heart? And all the other parts?
There are no real guidelines because the bridge interacts with the violin mass and stiffness (particularly the island between the f-holes), so the effect of thinning different areas of the bridge may have different effects on each violin. There are some scientific studies on the effects of "bridge tuning" that can give a general idea through a better understanding of the structural and vibratory aspects (rather complex) of the bridge, such as these two: oosterhofonline.net/pdf/Bridge_wood_removal_Rodgers.pdf archive.violinbridges.co.uk/wp-content/uploads/2015/06/ontuningthebridge.pdf Here you can find a very recent discussion on the dynamics and functioning of the bridge that illustrates well the complexity of the thing: ruclips.net/video/rL9btZHUCcM/видео.html Basically, it takes experience to try to predict the effects of carving, and a good dose of trial and error is indispensable. It is often necessary to cut two or more bridges for the same violin to understand the effects and which ones work best for that specific instrument.
Do you mean the difference between installing a rough and finished bridge? I don't have a video of the before and after comparison, but the difference would be huge, even small differences in measurements of the cutouts can make big differences in the acoustic performance, that's why these measurements are modified according to the needs of each violin. However, the effect of the bridge is mainly on the high frequencies, on the low frequencies it doesn't have much influence if the mass and rigidity are not very out of the ordinary. Regarding how the bridge works, I refer you to this specific conference: ruclips.net/video/rL9btZHUCcM/видео.html
@DavideSora thank you for your answer! I Am very beginner in violin... And mine is a cheap one... From china... Very cheap... 😅 I think how better violin sounds... This is why I ask... In mine not much difference, but in a better one small things cause a lot more impact... 😁
@@guilherme0stevan Yep, cheap violins are usually so stiff that the bridge has much less impact, but on more responsive violins the subtleties can be decisive. I don't know your playing level, but the violinist's technique can also be a determining factor in noticing differences. Then, the bridge works together with the sound post, the bassbar, the arching and thickness of the top, etc. It is the whole that determines the overall quality, the bridge alone cannot work miracles.🙂 It could also be that a very stiff violin may need a stiffer bridge or with more mass. Each case is a different case, and some are hopeless cases...😅
Ebony is too heavy to be suitable for bridges, so I suspect its effect on sound will not be as good as that of high-quality maple specially selected for bridges. However, I've never tried ebony (and honestly it's not in my plans) so I can only guess, but I wouldn't give it much of a chance🙂
I wouldn't recommend it, although this is a traditional technique that has certainly been used on fine violins as well. Keep in mind that the pinpricks must only be in the varnish, not in the wood, and that on the old violins around the foot of the bridge there is no original varnish left, only touch-ups made by restorers. So, when done with common sense, the pinpricks technique is not terribly invasive all things considered. However, as an alternative, a non-sticky tape can be used to mark the position of the feet, or a white grease pencil of the type used to draw on human skin for art or make-up purposes.
@@marcelogonzalezechazu9054 The tape works well, be sure that you can remove it without peeling off the varnish, the greatest risk of this technique. You will also need to make sure that no traces of glue from the tape remain on the surface, and that it does not contain aggressive solvents for the varnish
@@marcelogonzalezechazu9054 No, it's not Liquin, it's linseed oil. The label says "Drying linseed oil", also by Wintsor & Newton. However, I suppose Liquin could also be used, although I have never tried it because I prefer natural products. After all, Liquid is nothing more than synthetic linseed oil, precisely Alkyd resin.
The wood is maple, quite hard but a little less than those used for the Xylophone, which would be too heavy for a violin and would not work well for a violin bridge. Maple is ideal because it is light and hard, just the right mix of properties to get a good classic violin tone.

I'm sorry, I have no idea. But I think that as everywhere the price will vary according to the workshop that will do the work (name, experience) and also according to the quality of the violin on which the bridge will go
Sorry, I don't have any video on the cello bridge. Doing so would be more complicated than the violin because there are many different models, many possibilities, and many sizes. I suggest you refer to this site: archive.violinbridges.co.uk/812-j-a-beare-cello/ Many bridges with all measures indicated, and also a selection of recommended articles to read. They also make a printed book
Those that I have accumulated in forty years of activity🙂. The bridge knives you see in the video are one old Pfeil, one has the blade made from an old circular saw blade, and two (for bridge cutouts and bridge feet) I bought some years ago from an American artisanal blade maker, John Schmidt, who uses PM-X steel, similar to PM-11. very good blades. Then I have many other blades for other knives, like the very old F&D ones, very good, the golden ones that I don't know the brand (very old) and some Japanese Kogatana
@@DavideSora Wow.👍🏻 Thank you so much for your quick and detailed reply. I‘m getting a lot of help from teacher video. I am learning by studying now. Thanks to my teacher, I can learn more in detail and enjoy learning more. Thank you for posting useful videos not only for me but also for many people. teacher is a wonderful person. Thank you.😍
Oh, i came to the comments section to find out what the red dust is for the chalk fitting of the feet, is it just plain red chalk? Please enlighten me, I'm training and struggling to get my feet to make perfect contact with the front. edit: and my teacher wants me to do it all my eye, but I secretly want something to aid me.
Yes, it's plain chalk, the type used to write on the blackboard, it must be dry chalk without wax-like additives that some artists' chalk contains. Using chalk to get a good fit is quite common in lutherie and restoration work, in this case red chalk is used but for example for the bassbar and the neck setting the more common white one is used. However, developing the ability to work by eye as your teacher says, is essential anyway, and allow you to get very close to the final result quickly and without making mistakes, chalk is only used at the end to perfect the fit to not waste time. I honestly see nothing wrong with using it even during the learning process.

I'm new to the violin world, and I'm amazed of the amount of BS. Like.. shoulder rest costing a ton of money because they are light and add to the vibration/harmonics.. Oh god. The shoulder rest sits on the body, it cannot resonate.. That's a BS argument for charging more money. In this clip my issue is with the appreciation of handcrafting. I built myself a guitar and tested and tweaked it and measured its freq, etc. You remove a bit here and you listen and find out some freq respond better. You go even further and some other frequencies start to diminish, so you stop,. Etc. That the value of handcrafting. If you just do the shape without testing the sound step by step, there's no value in handcrafting. A laser cutter would be far superior. Then there's the Italian issue. It seems that just because the violin is made by Italians its worth a lot more. God.. the Chinese invented paper, umbrellas, etc. Do we value an umbrella more because its made from the country it was invented? What is wrong with this violin world (society)? In the guitar world there isn't such an amount of BS..
BS is everywhere, even the guitar world is not exempt from it, as is the rest of the world. Being aware of this helps to make distinctions by directing our choices. To me, skills, honesty, and work ethic are the fundamental factors to look for.
If you mean the C-shaped one you see at 2:55, it is not available in shops, you have to make it yourself with a piece of wire and two small pieces of wood. The typical wire used by luthiers is the one from the metal coat hangers from laundries, it's easy to cut and bend but with enough spring to hold the bridge in place.
@@DavideSora Thank you Davide, I figured that was the case and I have all ready been looking for the right gauge wire to do this, thank you for saving me time in searching and thank you for taking time to respond!

Hace un par de meses el puente de mi violín se estropeó y no tengo confianza para llevarlo con ningún Luthier de este lado del mundo :/, así que procedí a hacerlo basandome en varios videos, este en particular me ayudó bastante para hacerlo, claro, de forma amateur y con herramienta casera, gracias!
The most important thing to avoid damaging your violin is the good fit of the feet to the arching's curve and the bridge's structural strength. Of course, for the sound and aesthetics, going to a good luthier would have been better, but I'm happy to know that my video helped you make your violin playable again.🙂
Una obra maestra,gracias al canal por tan maravilloso video
Your work is excellent !
Thank you!
I literally just finished making my first bridge out of Australian bottle brush that I had left over from pruning. It's a harder timber but gives a bright, crisp sound.
The bridge has a decisive influence on the sound and in particular on high frequencies, maple is the most used and most tested wood, especially for a sound linked to classical music, but this does not mean that other types of wood cannot give results equally interesting. Experimentation is always the key, the ideal would be to make a traditional bridge in maple and others with different woods, so as to be able to compare the results on the same violin
@@DavideSora I do plan on doing this but I do talk to a guitar luthier regularly about this sort of thing. The interesting thing is that many classical guitar players consider instruments made from Australian timbers to project and give instruments unique tonal qualities, among these of course is Anna Vodovic and I often wonder why these species haven't made it into bowed strings as far as classical repertoire. I plan on making some more bottle brush bridges and some mulberry, I certainly prefer my bottle brush bridge over my violin's maple bridge.
@@jonathonaltmann4493 I have always encouraged the use of local woods, European maple is the most used because it has been tested for centuries, but when this experimentation began, Australian woods were certainly not available here in Europe, so who knows what would have happened if they had been available to the luthiers of the sixteenth, seventeenth and eighteenth centuries🙂
Such beautiful work

very enlightening
Thank you
Thanks for this video! The bridge of my violin was badly places and this really helped me to place it correctly. I even made my own video about it ;-)
Yes, if the bridge is not in the right position the relationship with the soundpost is no longer adequate, and even with small changes in this distance, the sound can suffer a lot. However, some older violins have the bridge intentionally placed in a different position with respect to the F inside notches, usually to compensate for too long a vibrating string, so the soundpost could be placed accordingly. Moral: Always check the bridge/soundpost relationship after moving the bridge. But if the sound of your violin has improved after bringing the bridge back to the correct position, it is a clear symptom that there is no problem with the soundpost. To get an idea of the correct soundpost position you can watch this video: ruclips.net/user/shortsALodkm5uF8s
keeping in mind that each violin will need a slightly different position based on its acoustic response and construction characteristics
Im curious how one knows if arms, legs and the heart of the bridge can be made even thinner so there is even less loss of energy from strings to top plate. I wonder if there were any physicists (or amateur experiments) who made public studies in whats the most efficient shape in relation to wood density before bridge will become too weak.
The dimensions of the various sections of the bridge can (and should) be optimized according to the response of the violin. There are many scientific studies on these aspects of bridge, but no one can give precise recipes because, in addition to the properties of the wood, the results are variable based on the characteristics of the violins, which are never the same. So the best system remains that of try and error, starting with a stiffer bridge with wider sections and modifying it little by little according to the acoustic response of the violin to which you are adapting it. It is a process that requires experience and often requires adapting more than one bridge to get the one that works best on that particular violin and for that player, because the sound has a component linked to personal taste that remains essential. If you are interested in scientific studies you can start with these which are available on the web for free:
hrcak.srce.hr/file/346888
oosterhofonline.net/pdf/Bridge_wood_removal_Rodgers.pdf
vsapapers.org/index.php/journal/article/view/4/13
You can find many others by searching the various scientific publication sites by paying modest amounts of money, such as this:
iopscience.iop.org/article/10.1143/JJAP.41.6291/pdf
I would google Joseph Curtin. He very probably has written on that very subject with the Acoustic Cat Gut Society, or whatever they’re called.
@@johngeddes7894 Thank you. After experimenting with carving bridges to as thin as possible. I understand now why people don't do it. If one removes too much mass, the dynamics range will decrease. So pianissimo becomes louder but fortissimo stays the same. It's harder to play quiet and control dynamics. For the sound it is similar as if one would use "Compressor effect" digitally. Thus certain amount of resistance (more mass) is desired in bridges.
¡Soberbio! ❤
Fantastic video.
Precise work !
excellent work ❤
Grazzie Maestro!
I never knew all that was involved in a violin bridge. Wow! how does one know when to quit carving?
Rocking frequency, material properties, and weight can give a clue ( ruclips.net/video/9P8n46DOaDg/видео.html ), but it basically depends on the sound of the violin the bridge was made for. The best thing would be to keep it slightly oversized, try the violin, and make changes to the bridge according to the result and expectations of the player/owner.
Of course, experience is needed to know how and where to intervene, and it can often be useful to cut more than one bridge to obtain the desired results, so as to be able to evaluate the acoustic effect of different bridges on the same violin. It is not something feasible for a factory or low-cost violin, but for fine violins it is the most sensible thing.
@@DavideSora Thank you Davide. By the way, have you seen Kevinleeluthier saying the bridge side of the tailpiece should be a little less than 90 degrees? I guess this is how Paganini had his violin set up?
@@TNungesser I don't know Mr. Lee personally and I don't want to criticize him, but I often find myself disagreeing with what he says, I may agree with some things but others just don't make any sense to me, bordering on misinformation. 😐
As for the bridge, tilting it back (toward the tailpiece) to bring the rear face into the bisector of the string angle might sound sensible, but it's actually a great prerequisite for seeing it bent back in a short time.
I think that at most it is the front face that must be on this bisector, but in reality it is a theoretical condition that is difficult to obtain or even just to verify in practice, also seeing that each string has a slightly different angle on the bridge and that the angle of the neck, the height of the bridge and the height of the saddle can vary instrument by instrument modifying the general set-up. In my experience, bridges made as you see in my video don't bend in any way when properly made and maintained, and another thing I've noticed is that leaning the bridge backward (towards the tailpiece) can cause problems when playing with the bow very close to the bridge ("sul ponticello"). So to me it's a "no-no", and I don't think Paganini's bridge was angled that way. Together with the violin the original bridge and fittings that he used are preserved, and observing how the feet are cut it seems that it was with a normal inclination (rear face vertical) even if it is difficult to understand this with certainty due to wear. It is also quite different from modern bridges, it can be classified as a transitional bridge between the baroque shape and the modern shape (it has no heart and has very small feet). Where does your guess come from?
@@TNungesser. You make one, fit it, play it , think about it……then you make another and repeat the process. Then you make a third…..and then you decide.
On a dark sounding, bassy violin this is done, most often on a Guarneri del Gesu model violin. It helps to give a little more bite and clarity to the violin that needs it. I wouldn’t do it on a bright sounding violin.
Que bella obra de arte Maestro,imagino que son años de conocimientos y una técnica exquisita y depurada para lograr tal resultado,yo he intentado ajustar mis puentes,pero no logro a tener resultados óptimos en el sonido final,hay desequilibrios en intensidad y textura lo que me ha llevado a hacerme muchas preguntas :
-Cuánta madera hay que sacarle al puente ?
-el acabado final del corazón,oídos y patas a solo estético o afecta de igual forma al sonido ?
-hay una tabla de medidas de grosor establecidas ?
-Están relacionados el grosor de las tapas del violín con el del puente ?
Un fuerte abrazo desde Puerto Varas Chile!!!!
(Sorry if I answer in English, but in this way others will be able to read my answer. However I don't speak Spanish and I should have trusted the google translator to write the answer, and I don't know if it does a good job...)
First of all, this video is only a condensed version, you will probably find many of the answers to your questions in the detailed series of all videos on the bridge, which I have collected in this playlist:
ruclips.net/p/PLaxadm6POX7EjpjW2BpAr1d_U8ITO5GFP
For example, in this video of the series you will find the indicative measures: ruclips.net/video/9P8n46DOaDg/видео.html
However, there are no fixed measurements, but each violin will need slightly different measurements to adapt the bridge to its construction geometry and sound response. The finish of the various elements (heart, kidneys, legs, etc.) mainly has an acoustic value, the aesthetic is only a consequence. By changing these cutouts you can adjust the response of the violin, especially in the high frequencies range. The wood to remove compared to the initial bridge blanks is a lot, to give you an idea its weight is reduced to almost half of the initial weight, but this obviously depends on how your bridge blanks are made, not all of them have the same raw dimensions when you buy them. However none of the surfaces of the bridge blank will remain intact, all will be trimmed to some extent. The thickness of the plates doesn't have much to do with the bridge, at least not directly. The sound of the violin will dictate how to make the bridge, and also geometric aspects such as the inclination of the fingerboard for the height and the position of the bassbar and the distance between the upper eyes of the Fs which will be considered to determine the width of the feet.
Making a good bridge that works well and lasts over time requires a lot of knowledge of the aspects involved, which are many, which is why the ideal would be to entrust the job to an expert professional violin maker.
Master piece.. 💐👍
Beautiful!
I'm on my third carved bridge and I can already say that I know how to carve. The third being the best bridge ever created Aubert De Luxe. What I have noticed with some sculptors, they are very wrong about the thickness of the bridge, taking too much of it they lose the power of the instrument, the more thickness you take, the less the sound transmitted to the violin is, and as much as possible must be sent to the instrument for a developed sound, therefore a balance must be found between the clarity given by a thin bridge in thickness and the force given by a less thin bridge, of course the most is taken in the head of the bridge, but as you go down you still need a thicker bigger than what most do. This is a finding of mine considering that I sing on a fairly old instrument with an extraordinary resonance, which after I put the Aubert De Luxe bridge on it in the style I described above, there was simply an explosion of extraordinary sounds. How much quality and attention matter. I'm wrong ? correct me if I'm wrong sir.
I would say that the concept you express cannot be considered wrong. Still, rather than talking of thickness alone, it would be more correct to speak in terms of mass and stiffness, which are clearly connected to the thickness, but not only: the properties of the wood and the heights (dimensions) of the various sections (arch, legs, ankles, waist) are an integral part of the picture in determining mass and stiffness. However, a bridge that is too thin in the lower part could indeed cause a slightly thin tone, but it remains to be established what we mean by too thin or too thick, these are rather abstract terms if not quantified.🙂
@@DavideSora😁♥️🙏 Absolutely perfectly, sir, you mentioned the other properties that need attention. Many congratulations, I respect you from Romania 🙏.
Good video. I have a moderately priced violin that has a superb tone. It is a nice hand crafted violin, but needs a better bridge and a new nut. The nut was cut with narrow string spacing of under 15mm, the original owner had very small hands. Someone tried to fix it by filling the string slots and recutting the grooves. It’s a mess. I’m going to cut a new nut and bridge.
To change the string spacing at the nut, making a new one is the way to go. If the bridge is in good condition and the strings are a little high on the fingerboard, it is possible to change the spacing by lowering it without making a new one. But considering that modifying or changing the bridge could affect the tone, the situation should be evaluated carefully.
@@DavideSora the shop I took it to originally said they dint want to remove the nut, so they filled the grooves and recut the slots. It was not done well. They said they didn’t want to remove the nut. I used one of my carving knives and it popped off after the second try.
I’m shaping the new nut. I cleaned and squared the area where the nut sits.
@@bremms1 It is possible to fill the string notches with cyanoacrylate glue and cut them in the correct position, but this is only a cheap solution that does not work very well, it may be acceptable only as an emergency repair if there is no time to make a new nut. As you may have noticed, removing the old nut is not difficult at all, and making a new one is not that complicated. However, it depends on the value of the violin and the hourly rate of the person doing the work, because it is a job that requires precision and a few hours of work. You can see how I make the nut here: ruclips.net/video/p0zvd5Uic5A/видео.html
Thank you, yes that was what I was thinking. This violin is worth $12-1500 dollars so I understand why they did that. I’ll look at your video before I finish the nut. I have some nice planes, files and chisels. My carving blade is a flat bar of hardened tool steel. I made a handle for it, but prefer it without.
You have been very helpful.

You're welcome.
great videos of you..i enjoy to watch every each of them.Is in any chance possible to get the measures of that tool to measure the right string position and spacing? thanks a lot.

@@DavideSora yes that one :)
@@passionisart Well, not a very high-tech tool🙂, but it works like a charm and is extremely accurate. It is made from a 2mm thick willow violin lining scrap, approximately 70mm long, 15.7mm and 9.7mm wide. The horizontal lines should be drawn with a square when it is still rectangular, then adding the same taper on both sides. The horizontal pencil lines are drawn almost randomly, about 1.5 mm apart. The three widest ones at the top are for viola, the widest is about 12.2 mm and the narrowest is 12 mm wide. The others are for violin, the thickest one is my average reference and measures 10.9 mm in the center of the thick line. The purpose of this tool is not to set a measurement, but to check that there is an equal spacing between the strings. A divider is used to set the total spacing and the spacing between each string. This spacing can be varied according to the violinist's preferences, my reference measurement (the thick pencil line) is just for when I do not have particular indications from the violinist, so I set a not-too-wide or not-too-narrow spacing that should work for most violinists

@@DavideSora I see, thanks again!
I just put my first bridge on. Question: When you are finished and have it in place and the violin doesn't sound like you want it to , is it then you realize you took off to much or you need to reshape it more and in what area.? I tried to match the one that I replaced. I do think I can do better next time and may geta dozen of them and work on it, But what I'm not sure of is on what part of the bridge is vital to making sure the sound is functional.
Simplifying to the extreme, the most sensitive area is the waist, but the distribution of masses and geometry introduce many variables. A bad fit of the feet is the first thing that could compromise the sound. In short, it is too complex to put it in a post on RUclips, many articles have been written on this topic that could be useful for you to get an idea. For example this one here: fiddlerman.com/wp-content/forum-media-uploads/elcb/2021/04/Bridge_wood_removal_Rodgers.pdf
or this other one here: www.mdpi.com/1424-8220/13/11/15290
You will find many other interesting articles on the violin bridge in the references paragraph of these two articles.
Lot of pages to study, I did. Unfortunately, experience and many bridges for many violins play a decisive role in obtaining the necessary sensitivity. Bridge and set-up are the hardest parts to learn in violin-making.
@@DavideSora Thanks... I got everything I need to shape the piece of wood. I certainly got some reading to do. After I read all of this maybe my question as to Why don't they already come (Other than than the feet ) ready to go? Seems to me they are leaving it up to you to reach a sound that you prefer. Taking wood off here and there seems to be arbitrary. I see you measuring. Is it the same for each bridge? or do you just hope? It's an ole fiddle I got ...I put new pegs on it, new bridge, strings, sound post is perfect...sounds better than it did... but just wondering if I can make it sound better..it maybe all she can give...again thanks for your input.
@@DavideSora This is from what you sent me....
Consequently, a maker
trimming a bridge does not have to be concerned that his work
will change the nature of the bridge as a vibrating system.
Thus, the options now used by violin makers appear to
make substantial reductions possible in all three bridge frequencies and offer ways to reduce frequencies selectively. It is
no wonder that the advice received from makers was difficult
to understand.
@@fordjubilee As I was saying, it's complicated, you need experience and a good dose of trial and error to acquire it
@@fordjubilee In this video ( ruclips.net/video/9P8n46DOaDg/видео.html ) I indicate two sets of measurements, which indicate the minimum and maximum of my preference.
Consequently, you can deduce that I don't always use the same measurements, because there is a need to adapt them to the properties of the material (as usual, two pieces of wood, and this also applies to bridge blanks, will never be the same), and to the sound we like, what is best is not the same for all of us. Then, it seems to me that some can never be satisfied with what they obtain, thinking that something can always be improved simply by modifying the bridge or the position of the soundpost, when often the limit is the violin we have. In fact things can be changed, but not always for the better, or simply obtaining different but equally acceptable sounds depending on taste. Given that you say your violin is much improved, I would not modify the current bridge but make others with different characteristics (measures, type of wood, etc.) and replace them one after the other to see what happens to the sound. In this way, you will be able to choose the bridge that gives you the best results, and if this is not the case you will always be able to restore the initial conditions and be satisfied with the improvements obtained with the first bridge. a lot of work, but very informative to gain experience. You can also modify the bridge step by step without removing the strings to eliminate the inevitable variables that this would entail, listening to what happens to the sound after each small change in the measures. This is also very informative but only from a learning perspective: at the end of the process, the bridge will be destroyed and unusable, so you will have to build another one, trying to put into practice what you have learned. It will probably be like starting from scratch because the memory of sound lasts very little (scientific fact), but you can understand which parts are most sensitive to changes, which is no small feat.
Beautiful carving knives, where are you purchasing them?
For the knives I only purchase the raw blades. The wooden handles, and of course the shape and sharpening of the cutting edge are made by me. The blades come from different manufacturers, a couple are John Schmidt's PM-X steel, one is an old Pfeil and one is made from an old circular saw blade. In any case, any good quality blade will serve the purpose well, if shaped and sharpened correctly, which remains the most difficult undertaking
Hello, thanks for the great video!
Just wondering what are those powder used in calibrating the bridge feet?
Red chalk. A simple blackboard chalk, crushed and pulverized. You have to make sure it is the dry type, without any additives like waxes or fats to make it softer as some artist chalks have.
You can see it in more detail in this video:
ruclips.net/video/jA5_5GiQm-Q/видео.html
Hi - Great Work! What's the height of the wooden stick you used for labeling the height of the bridge on the E string side and the G string side? This is before you label the top of the bridge arch. Thank you!
My stick is 5mm thick on the E side and 7mm on the G side, the bridge needs to be a little taller than the finished height at this stage.
@@DavideSora Great! Thank you!
@@DavideSora I am sorry - What kind of oil do you use to seal the bridge at the end. It's hard to see it.
@@soccerplayerfan251 It is cooked linseed oil. Use it extremely sparingly, it must only seal the surface without penetrating deeply into the wood. Any absorbed oil never dries and you would risk getting a muted sound

Hello friend, very good work and very well detailed, the violin bridge, would you be so kind as to recommend me where I can get the stamp that puts on the bridge?
I had the brand made by a stamp factory, any stamp and plate shop can do it, just specify that you need a fire brand. There are also artisans specializing in fire brands, if you do a google search you will find several.
Of course you will have to put your name not mine, Davide Sora is an officially registered trademark and its use is under strict surveillance
😉🙂
@@DavideSora Thank you very much my friend, sorry for not specifying, my intention is to make my own cello under my name, that's why I asked you where I send you to make it. My label is F.CENDEJAS
@@franciscocendejas1226I was just kidding, I knew you'd put your name on it😅
If you do a google search for "electric branding irons for wood" you will find many that can do it for you including the electrical part. Mine is an old brass brand made here in Cremona almost forty years ago, in a small shop that makes nameplates for doorbells and stamps, which I adapted to an old soldering station for electronic components
@@DavideSora Thank you very much teacher in truth I thank you very much for your understanding and much more for your time to answer me thank you I will search for you and indicate me in google thank you friend
👍👍👍❤

Ciao. I ponticelli da violoncello hanno misure e dimensioni troppo variabili per poter dare sinteticamente indicazioni utili sulle misure. Ti suggerisco di consultare questo sito archive.violinbridges.co.uk/812-j-a-beare-cello/ dove puoi trovare molti esempi di ponticelli di violoncello con tutte le misure disponibii se ti iscrivi.
Hello. How do you know that a bridge of a good quality of wood? I got some from a local shop. They seemed to be OK but turned to be soft maple wood. All of my installed bridges went bent a lottile in a year or two.
Understanding if the wood is of good quality is a matter of experience, but it is possible to get an idea by observing the compactness of the grain and, above all, the direction and sharpness of the medullary rays, which must be long and continuous by observing the bridge from the side and as narrow and sharp as possible by observing the bridge on the faces. This would most likely indicate a hard and stiff wood, although sometimes a softer wood may be needed for example in the case of violins that are too harsh in the high frequencies. As for the bridge bending, the cause is often an incorrect inclination of the bridge with respect to the vertical. In fact, with the tuning, the strings will tend to pull the bridge forward, which, if it is not brought back to the correct position, will inexorably bend in a short time. A properly cut bridge held in the correct position (tailpiece side perpendicular to the line of the ribs, i.e. to the gluing line of the top plate) can last many decades before starting to bend.
@@DavideSora do you have fingerboard radius 42 mm?
@@los5mandarinas I make my fingerboards with a composite radius, one at the nut, one in the center and one at the end of the fingerboard. Only the radius at the nut is 42mm. You can see how I make the fingerboards in this condensed video: ruclips.net/video/fc8GM2DzFa4/видео.html

@@DavideSora Thank you very much for this explanation !
Also, would it be inadequate of me to ask who is your bridge provider ?
Looks like Aubert or Milo Stamm stamp but it's hard to tell from this angle/distance.
I'm glad I watched this video, and it would seem you uploaded plenty more videos, I'll be sure to watch them all. Your jigs are really great too and inspiring, thank you again for sharing your knowledge !
Are there instructions as to Why to carve the bridge the way you do? I understand why one would carve the feet to fit to the top of the violin. But why make the bridge a very specific thickness and how think? Why carve the kidneys and how to know how much to carve? And the heart? And all the other parts?
There are no real guidelines because the bridge interacts with the violin mass and stiffness (particularly the island between the f-holes), so the effect of thinning different areas of the bridge may have different effects on each violin. There are some scientific studies on the effects of "bridge tuning" that can give a general idea through a better understanding of the structural and vibratory aspects (rather complex) of the bridge, such as these two:
oosterhofonline.net/pdf/Bridge_wood_removal_Rodgers.pdf
archive.violinbridges.co.uk/wp-content/uploads/2015/06/ontuningthebridge.pdf
Here you can find a very recent discussion on the dynamics and functioning of the bridge that illustrates well the complexity of the thing:
ruclips.net/video/rL9btZHUCcM/видео.html
Basically, it takes experience to try to predict the effects of carving, and a good dose of trial and error is indispensable. It is often necessary to cut two or more bridges for the same violin to understand the effects and which ones work best for that specific instrument.
Don't have before anda after of the sound?? What it do to the sound?? How strings work with this action??
Do you mean the difference between installing a rough and finished bridge? I don't have a video of the before and after comparison, but the difference would be huge, even small differences in measurements of the cutouts can make big differences in the acoustic performance, that's why these measurements are modified according to the needs of each violin. However, the effect of the bridge is mainly on the high frequencies, on the low frequencies it doesn't have much influence if the mass and rigidity are not very out of the ordinary. Regarding how the bridge works, I refer you to this specific conference: ruclips.net/video/rL9btZHUCcM/видео.html
@DavideSora thank you for your answer! I Am very beginner in violin... And mine is a cheap one... From china... Very cheap... 😅 I think how better violin sounds... This is why I ask... In mine not much difference, but in a better one small things cause a lot more impact... 😁
@@guilherme0stevan Yep, cheap violins are usually so stiff that the bridge has much less impact, but on more responsive violins the subtleties can be decisive. I don't know your playing level, but the violinist's technique can also be a determining factor in noticing differences. Then, the bridge works together with the sound post, the bassbar, the arching and thickness of the top, etc. It is the whole that determines the overall quality, the bridge alone cannot work miracles.🙂 It could also be that a very stiff violin may need a stiffer bridge or with more mass. Each case is a different case, and some are hopeless cases...😅
I saw an ebony bridge for sale....good resonance or not?
Ebony is too heavy to be suitable for bridges, so I suspect its effect on sound will not be as good as that of high-quality maple specially selected for bridges. However, I've never tried ebony (and honestly it's not in my plans) so I can only guess, but I wouldn't give it much of a chance🙂
would you make a mark with a sharp tool on the top of a fine violin as well in order to guide you through the process?
I wouldn't recommend it, although this is a traditional technique that has certainly been used on fine violins as well. Keep in mind that the pinpricks must only be in the varnish, not in the wood, and that on the old violins around the foot of the bridge there is no original varnish left, only touch-ups made by restorers. So, when done with common sense, the pinpricks technique is not terribly invasive all things considered. However, as an alternative, a non-sticky tape can be used to mark the position of the feet, or a white grease pencil of the type used to draw on human skin for art or make-up purposes.
@@DavideSora Nice, I use non-sticky tape
@@DavideSora Double boiled linseed oil? the bottle looks like Liquin, from Winsor and Newton 🤔
@@marcelogonzalezechazu9054 The tape works well, be sure that you can remove it without peeling off the varnish, the greatest risk of this technique. You will also need to make sure that no traces of glue from the tape remain on the surface, and that it does not contain aggressive solvents for the varnish
@@marcelogonzalezechazu9054 No, it's not Liquin, it's linseed oil. The label says "Drying linseed oil", also by Wintsor & Newton. However, I suppose Liquin could also be used, although I have never tried it because I prefer natural products. After all, Liquid is nothing more than synthetic linseed oil, precisely Alkyd resin.
from minute 0:15 , Is the wood as hard as Xylophone wood?
The wood is maple, quite hard but a little less than those used for the Xylophone, which would be too heavy for a violin and would not work well for a violin bridge. Maple is ideal because it is light and hard, just the right mix of properties to get a good classic violin tone.

How much they will charge for, bridge work in Canada ..? Any idea.
I'm sorry, I have no idea. But I think that as everywhere the price will vary according to the workshop that will do the work (name, experience) and also according to the quality of the violin on which the bridge will go
too much
Hi maestro
You don't have direction for cello bridge how made
Sorry, I don't have any video on the cello bridge. Doing so would be more complicated than the violin because there are many different models, many possibilities, and many sizes. I suggest you refer to this site: archive.violinbridges.co.uk/812-j-a-beare-cello/ Many bridges with all measures indicated, and also a selection of recommended articles to read. They also make a printed book
Hello! May I ask what kind of knife you use?
Those that I have accumulated in forty years of activity🙂. The bridge knives you see in the video are one old Pfeil, one has the blade made from an old circular saw blade, and two (for bridge cutouts and bridge feet) I bought some years ago from an American artisanal blade maker, John Schmidt, who uses PM-X steel, similar to PM-11. very good blades. Then I have many other blades for other knives, like the very old F&D ones, very good, the golden ones that I don't know the brand (very old) and some Japanese Kogatana
@@DavideSora Wow.👍🏻 Thank you so much for your quick and detailed reply. I‘m getting a lot of help from teacher video. I am learning by studying now. Thanks to my teacher, I can learn more in detail and enjoy learning more. Thank you for posting useful videos not only for me but also for many people. teacher is a wonderful person. Thank you.😍
Oh, i came to the comments section to find out what the red dust is for the chalk fitting of the feet, is it just plain red chalk? Please enlighten me, I'm training and struggling to get my feet to make perfect contact with the front. edit: and my teacher wants me to do it all my eye, but I secretly want something to aid me.
Yes, it's plain chalk, the type used to write on the blackboard, it must be dry chalk without wax-like additives that some artists' chalk contains. Using chalk to get a good fit is quite common in lutherie and restoration work, in this case red chalk is used but for example for the bassbar and the neck setting the more common white one is used. However, developing the ability to work by eye as your teacher says, is essential anyway, and allow you to get very close to the final result quickly and without making mistakes, chalk is only used at the end to perfect the fit to not waste time.
I honestly see nothing wrong with using it even during the learning process.
@@DavideSora Honestly, thanks so much!
Mia curiosità
È legno di corniolo??
No, è acero.. Il corniolo probabilmente sarebbe troppo duro e pesante per un ponticello.
Why does every one of these bridge videos start with... a bridge. Seems like it's almost ready before we got here.
So that you can see what the final result is, and skip the whole video. It seems that people have an attention span of no more than 15 seconds😅
it's uneven
It is, It must be
Con lija 1000al sale mejor.
El papel 1000 es demasiado fino, pero si te sientes cómodo, úsalo. Lo que ven en el video es papel 400 usado y desgastado, creo que es comparable a un 600

@@carlosrosasquinones4036 Lo siento, pero no es posible dar tales indicaciones sin ver el violín y el puente, sería demasiado poco fiable. Deberías llevarlo a un luthier experimentado para mostrárselo y escuchar su opinión.
@@DavideSora Le agradezco mucho su respuesta.
If it was truly from start to finish the video would start with an unworked block of wood.
I'm new to the violin world, and I'm amazed of the amount of BS.
Like.. shoulder rest costing a ton of money because they are light and add to the vibration/harmonics.. Oh god. The shoulder rest sits on the body, it cannot resonate.. That's a BS argument for charging more money.
In this clip my issue is with the appreciation of handcrafting. I built myself a guitar and tested and tweaked it and measured its freq, etc. You remove a bit here and you listen and find out some freq respond better. You go even further and some other frequencies start to diminish, so you stop,. Etc. That the value of handcrafting. If you just do the shape without testing the sound step by step, there's no value in handcrafting. A laser cutter would be far superior.
Then there's the Italian issue. It seems that just because the violin is made by Italians its worth a lot more. God.. the Chinese invented paper, umbrellas, etc. Do we value an umbrella more because its made from the country it was invented? What is wrong with this violin world (society)? In the guitar world there isn't such an amount of BS..
BS is everywhere, even the guitar world is not exempt from it, as is the rest of the world. Being aware of this helps to make distinctions by directing our choices. To me, skills, honesty, and work ethic are the fundamental factors to look for.
where can one find the wire bridge holder caliper that you use for bridge alignment? I've looked everywhere. Thank you! Wonderful!
If you mean the C-shaped one you see at 2:55, it is not available in shops, you have to make it yourself with a piece of wire and two small pieces of wood. The typical wire used by luthiers is the one from the metal coat hangers from laundries, it's easy to cut and bend but with enough spring to hold the bridge in place.
@@DavideSora Thank you Davide, I figured that was the case and I have all ready been looking for the right gauge wire to do this, thank you for saving me time in searching and thank you for taking time to respond!
