Marking the purfling channel and designing the bee sting
Marking the purfling channel, stopped just before the corner and penciled in the bee sting point. I'll do a little final adjustment later before making the final cuts.

Adjusting the edges before purfling
Просмотров 2354 часа назад
The edges needed a little adjusting with the scraper before working on the purfling.
Arch Contours

Checking the cross arch shape. Overall it's looking good, just some slight irregularities in the lower bout. I'm just being picky, it looks good.
Final smoothing of the arch
Просмотров 131День назад
First I drew contour lines and could see it had some high area in the lower bout. So I smoothed those out and also smooth the whole arch with a small plane. Then scrape the whole arch with a scraper. I did a little more off camera but this shows most of it. Next comes the purfling... Stay tuned.
Fluting the corners
Просмотров 15514 дней назад
This video shows the fluting of the corners. Previously the fluting was carved all around the outline skipping past the corners. This is a short video since I had difficulty getting a good camera angle and getting the lighting right. Also it's sometimes hard to get a good closeup video with an iphone but at least it shows some of the process.

flattening edges and reshape arching

      @CooperViolins День назад

      I know it's hard to see but if you've seen some of my arching videos, I leave a flat area down the center line and work into that. So to my eye, there is still just a hint of flatness down the center especially in the lower bout. You can kind of see it just below the lower corners. Probably it would not be visible to anyone but me, only because I know it was there. Also it seems just a little bit not quite flat enough near the button where the neck will attach. I like to see it quite flat right over the end blocks. If you look at CT scans of original Stradivari violins it's quite flat right over the blocks. The tail end looks good though.

    • @CooperViolins
      @CooperViolins Месяц назад

      The cleats work well keeping the plate steady but it has a tendency to lift up and out when rough gouging. It didn't do that with the pins. I'll have to use a clamp on one end to hold it down. But at least it's a lot less wiggly now. :D I'm trying to make fairly quick progress on this one.

    • @BrianTimmonsTX
      @BrianTimmonsTX Месяц назад

      @@CooperViolins Yeah, the cleats combined with a clamp or holdfast ought to be ideal for the initial heavy work. In related news, I've ordered a full set of tone wood for my first violin build, and it should arrive here on Friday! 😁 I've made an online acquaintance with a really cool guy that's a recent graduate of the Chicago School of Violinmaking. He's been giving me lots of good pointers and encouragement. On his advice, I ordered a set of European spruce and maple. He said that in his experience, their American counterparts are more difficult to work with for someone that's just starting out. Apparently they're more resistant to smooth planing and gouging, and like to tear out more. He recommended me a supplier in Slovakia, and their selection looks amazing. I'll probably use them on better future builds. Instead I went with International Violin for now. They're out of Baltimore, so shipping to Texas won't take nearly as long, and I don't have to fuss with customs or VAT taxes. When I placed the order with IV, in the comments I mentioned, "Wish me luck on my first build!" Also ordered two sets of purfling, because I want one to practice with. Put in the order late in the afternoon. So then the next morning, a rep from IV actually calls me, asking if maybe I want to use fiber purfling instead of wood for my first build. It's apparently much easier to bend and work with. I mentioned that I've already dipped my toes into bending wood with my citole project, so I have at least *some* experience. Not much, but some, at least! And besides, I want to learn how to do it properly from the outset, which is why I ordered an extra set for practice. I want to practice doing some corners to get comfortable with the process before I attempt it on the actual front and back plates. He agreed that was a good idea, and I asked if they maybe have any scrap pieces of wood that they're just going to toss anyway, could they just include some in my box instead? He said he'd look for some, and that he personally picked out a nice looking set of wood for me already. I really appreciated the thoughtfulness and willingness to help a newbie like myself. I haven't got the wood yet of course, but thus far, I think it's safe to say they've earned my business going forward. Can I ask if you have any preferred suppliers, or that matter, any I should avoid? Thanks!

      IV is good, I've ordered from them, some spruce and purfling and I forget what else. This is only my second build, not counting the one in 1985, and I got the wood in exchange for making a walking cane for someone on MN. Although I did have to buy a new spruce set since I messed up the first one, mistakenly planed it down to 12mm. oops! :D If I build again, and I would like to, I may try some Slovakian. I'm in some violin facebook groups and you often see advertisements there for tonewood. I used wood purfling and didn't have any difficulty bending it. Got that from IV. I'm getting close to purfling but need to do some more shaping on the plate first. I only have some limited time in the afternoons and week ends to work but I'm trying to make rapid progress. I know you're excited to get the wood delivered and I'm looking forward to seeing your progress on the build. I had the morning off today, so I started refurbishing an old thickness caliper that I made from a kit in 1985. Striping the old ugly finish off and making some new parts with brass.

    Me again! Glad to see this progressing. One thing I noticed is how much the workpiece wobbles in the cradle. I think maybe the dowels aren’t quite enough to hold it securely, and you’d have an easier time cutting on it if the workpiece was better secured. Granted, this is coming from a guy that hasn’t even started his first violin build, so it’s not like I’m trying to act like an authority on the subject. Still, search for “Davide Sora cradle” to see what appears to me is the ideal violin cradle. It has adjustable cleats that hold the workpiece with complete security and no wobble. It probably wouldn’t be too hard to modify your existing cradle along these lines. Note: All the subtitles on Davide Sora’s videos are in Italian, but if you click on the video description, he includes English translations as well.

    • @CooperViolins
      @CooperViolins Месяц назад

      You're right it was a bit loose. I checked the plate on a flat surface and it is flat so then I planed the surface of my plate holder and it's much less wobbly now. The plate holder had warped just a little since I made it a few years ago. The pins are not ideal, originally I made a copy of the cradle that is in the Stradivari museum in Cremona. But for sure Davide Sora's cradle is much better. I have watched all of his videos several times and that's basically how I learned to build, so I try to emulate a lot of his technique. I'm thinking of making some cleats like his and attach them to this cradle vs. making a whole new cradle. I need to figure out how to handle comments on my videos. I had a nasty one that I deleted and now they are all on hold until I approve them.

      @@CooperViolins I'm in the middle of building a medieval citole, and will post a video once it's done. I'm shooting it on an iPhone as well. Over the course of the build I noted something interesting about most good violinmaking videos, that they usually work in a darker room with a lamp providing direct, raking light from the side. Not only does this actually look much better on camera, it makes shadows from irregular surfaces that much more obvious. So it's kinda like cheat codes for finer work during carving and finishing prep. The slightest blemish really stands out. I grabbed an adjustable lamp and fixed it to my workbench, put in a 40 watt soft white bulb, and turned off my overhead fluorescents. Plenty of lighting for what I'm doing, and on camera it makes the details pop, with good contrast, and the wood tones are much more warm on screen.
