I removed a small part of the video showing the final product, for compliance reasons. Don't worry, that does not alter the machining content, but I want to be on the safe side.
Compliance... sounds like government work...
@@douro20 Compliance is something absolutely common with industrial customers
@@StefanGotteswinter Compliance is industry 101.
Please do the video about tolerances. Bitte schon! Proooszę. I know it is dry, but it's crucial...
Beautiful work Stefan! As you can see, no one cares about video length when the content is excellent.
ATB, Robin
Thanks Robin! Seems like I will stay with the long format instead of splitting it up into 3 videos.
What you call "a very dry topic" to me sounds like a great video.
Seconded
Thirded
Forthed!
"dry".....parched....!
In the states we have a show called “how it’s made” that quickly runs through some of the ways that both usual and somewhat unusual items are made. None have the details let alone the rationale that you provide. The work that you consider fun, and the tooling you make to do it is fascinating! Thanks for the work that you have put into filming and editing your “hobby “ to educate and entertain those of us who enjoy seeing a master at work!!
Some people handle work with cranes, others with tweezers :) Definitely an example of mechanical art!
i hate being annoyed at high velocity pieces of metal impacting my skull
Yessss a video about tolerances!
Do it please
WhooHoo a new Stefan video. Does life get any better.
No, no it doesn't.
@@danoneill8751 jep, life did not get better, but, another lesson learned, abd some fantastic vid to push it to the button pushers, talkinf bullshit about 1µ or 1/10 od a thou.. ;)
I enjoyed this. A special thank you to your client for providing the "what for".
Tom Liptons toothpick only hollow with an o-ring groove. Cool.
At 42:20 when you showed the aluminium sub-collet with all the featured bored in and a relief machined into the outside to make it flex and conform to the part better, I was moved.
Stefan, I admire not only your machining skills, but also your ability to explain so clearly what you are doing and show the tooling. I hope you will be able to continue this and teach us to work accurately.
Camera work & lighting is great and gets better every video. Makes the TOT/GTWR vids so much more engaging than others.
Did I enjoy it, yes I did.
Lengthy? The time went in no time at all. Time flies when you are enjoying yourself.👍
Excellent video. Thank you. As a recently retired clock and watch maker who makes some pretty small parts I find your videos to be absolutely top quality and inspiring. Best in all of your endeavors.
Dont know what to say. Amazing workmanship. One of the best explained videos out there.
A great method of doing the right process and procedure at the correct time. Thanks for making this video and sharing it with us Stefan.
I like the way you are using "microns" rather tenths or hundredths of a millimetre. Others will disagree but I find it more intuitive.
Thats the general feedback I get, I will go for that in future :)
knew a machinst, his nickname was 'µ'...
Very cool Stefan, I love the micro tooling you showed. Great video, thanks!
With out a doubt, the best channel on RUclips ! Thanks a million. And it was one hour long - Awesome
Great to see the detail on the tools you used for boring, the pin-orientation makes a lot of sense👍 It's also great that the customer allowed you to say what this particular "flux capacitor part" is actually used for👍👍
That 1mm deep hole drilling went easy using the "Sliding Head " function of the new lathe.Great camera work.
Fascinating work as always. I like the way you do it Mr G! Thanks for all the tips and good humour.
I am amazed by the perfection of your work. Seeing this micromachining makes me remember a very good professional stage of my life. Thank you.
There’s a lot going on in this video, nice work! This almost looks like normal sized work until you see the boring bar size next to your fingers! It puts everything in scale. Thanks for a great video! That’s two days in a row, keep them coming!
Wow, nice work! Love your custom ground tooling. Was the first thing I noticed 😊. Lots going on in this video, thanks!
Nicely done Stefan. Love the indexing feature of the boring bar system.
THAT WAS FANTASTIC, ONE OF YOUR BEST VIDIO, SO WELL EXPLANED. REALY ENJOYED IT. THANKN YOU. FROM THE WINDY U.K.
That was Epic !
Plenty of good information and tips in that video Stefan !
Fantastic camera work also , I can only imagine how difficult it is to make those small parts with a camera always getting in your way !
"I do not have much interest in work with large material removal or large parts." That may be the most German thing a giant German can say. Well done on the parts & video.
Well the Germans make some of the best very large parts as well.
@Thu Nell Ⓥ Small pp.
We can tune in to Adam or Keith if we want the bigger stuff. Very interesting presentation, Stefan.
@Thu Nell Ⓥ ;) highly precise, over engineered, and, no humor... ;)
jep, Stef is a complete different clas of guys... it's beautifull even just to listen to the videos, while I'm in the toolshop... ok, too often I have to go into the room, to repeat and see, what he did.. ;)
Wow, micro machining for an hour, fascinating stuff Stefan, and amazing precision techniques, cheers!
Excellent work, that Guhring boring bar is impressive, I would need a macro lens to even see it 🤔🤔.
Very impressive photography. Thanks for sharing.
I am another who really looks forward to your videos. I really enjoyed this one.
Thank you Stefan.
Immensely enjoyable Stefan, as always. I did a lot of small detail work and it was always my favourite area. It would have been nice to have had some of the tooling you showed.
Awesome video.....excellent discussion/demonstration/build....really enjoyed the end of the vide as you discussed the various tooling holder alignment......ATB
Thank you for your videos. They are great I look forward to each one no matter how long are short.
I came pretty close guessing beam splitter. Another great video! Thank you for posting it.
Excellent video once again Stefan. I really enjoy these tight tolerance parts video's. Thanks for sharing. regards from the UK
Wish I could visit your shop. Love the elegance and accuracy of your work, and the deep knowledge level you demonstrate.
Compared to what you do, a clock maker would be a hammer and crowbar mecanic. It's unbelievable.
Obviously a man who loves his craft! Thank you for sharing!
I love 303. I’ve made a number of different, complex parts out of it. What’s good is that corrosion resistance is equal 304, the most common stainless, but machines very easily. Very easy to cut thin parts, small holes, threading, etc. A major advantage is that it just work hardens slightly.
When you said '70µm drill' @43:03 I nearly had a heart attack lol!
Fred Genius dose 700um sounds better? I probably brake those just by looking at them...
@@emilgabor88 Yeah, 0.7mm. Smallest I use is 0.35mm, they break if I look at them!
Fred Genius mie was 1mm ,the smallest that I could handle.
Blockbuster indeed. I learned a lot here, perhaps enough to consider reasonably changing my job title from librarian to apprentice toolmaker (or both?). The panning shot rotating around the centred radial cut was wonderful and almost like something a CNC could do which is a lesson in itself. *Smashes like button*
Beautiful job Stefan! :)
Yikes! That was amazing work. It's hard enough to make big parts accurate, but the small stuff is a whole other game. Impressive work.
Excellent video with the best commentary on youtube.👌👍👏👏👊🏼
absolutely beautiful work
I'd be really interested to get a better understanding of ISO tolerances.
It's reasonably easy, look here for example: www.engineersedge.com/manufacturing/preferred_mechanical_tolerances_metric_iso_286_13166.htm
There is a couple of good YT videos on the topic. It is a really dry topic.
@@arnljotseem8794 Thanks! I've started with FutureFab CNC & 3D Printing's "Limits, Fits & Tolerances" for starters. Let me know if you have any specific recommendations.
@@AdventureswithaVerySmallLathe Not really. I started on two , this one on " ISO fits" among them, from a fellow hobbyist: ruclips.net/video/wvVMs2BZdeU/видео.html
but I didn't finish any of them. I instead read what Machinery's Handbook had to say about the topic, and also referenced Metal Engineering Textbook (Europa Lehrmittel) Gave me the understanding I needed
It's all fun and games until you have to know GD&T. Fun but tedious.
Every time I watch your videos I admire haw sharp is your tools and the precision!
Nice job! I love it, clear, precise, sharp, flow less accurate. f...
bravo stefan, BRAVO a tour de force. and you seem to have granted my request for more run-time, less editing. double bravo for how well you pulled it off! poppy's workshop says HI
Goodness me! That must have been a *huge* snail! Thanks for a very interesting insight into the world of micro-machining!
Really enjoyed the long format video & def want a video about iso tolerances!
I've forgotten almost everything I knew about ISO tolerances, so a refresher would be nice.
Very impressive work. Well done 👍
Truely impressive work...
Excellent work!
And amazing !
Thank you Stefan that was very interesting - I didn't realise it was a lengthy video until you said "lengthy video".
Fascinating as always, Thank you!
It's always nice how you put things into perspective... Here I am, struggling with some tricky cuts while drywalling, and meanwhile, Stefan is making some ant jacuzzis...
Stefan, number 1 machinist!
als gelernter Feinmechaniker ( in den 1970ern ) ist das für mich pure Entspannung; ich bräuchte eigentlich nur noch diese Art von Arbeit in meinem letzten Lebensabschnitt und sonst nichts mehr
Very nice work, I always like the small and complex precision parts, because you need to use all your skills to get it done, sometimes even coming up with new ideas.
Wonder what this will be for, propably some fluid is going to go through there.
Edit: commented too fast again. That's some really interesting stuff your customer is doing there.
Very informative - thank you for posting. Pete
Thank you, I enjoy your videos very much.
Your an inspiration Stefan. I notice a new vice in the shop. Looks very similar to my latest addition, which for a distinct hobbyist like myself, is a significant step up from the Vertex I was using previously. In the future I hope to see some new material from you regarding the Gerardi and what you plan to do to improve its functionality.
Thanks!
Yes I will do a video on the Gerardi - I am already filming here and there short segments on it.
Thanks for the video.
very good video..thanks for your time
1:01:34 I don't guess it matters that the through bore interescts with the angled counterbore? These parts are well beyond my shops capabilities. Most of my machines have run out that is half the size of the hole you bored. lol
Yes, that does not matter, its drawn that way.
Almost everything you do is also beyond my capabilities ;)
You are the master Stefan, very interesting!!
NIce video. You realy amaze me. Dedication that you have... precision, love to watch your videos, there is no "dry topic" here. And since i have the same lathe like yours, i am even more thrilled by your videos because you move boundaries what can be done in a homeshop.
Stefan nice to see your technical work comparing my work on a 72" boring Mill it's like night and day difference .😨
Great video Stefan
I think anyone coming here is truly interested in your detailed technical information, so the tolerance video would be a good one. I highly appreciate the experience and knowledge that you offer, it's not often I can sit through an hour long machining video
Wow sounds like I'm sucking up to the teacher for extra marks lol
Thank you!
GREAT VIDEO !!!
I also find being smacked up side the head with steel parts “reasonably annoying”! Great quote. Mind if I use it?
Great video
Wow! How the heck do you bid a job like this? Incredible precision and just beautiful craftsmanship. Thanks for sharing 😊👍
Guess the hours, add the tooling required, add 25% and hope for the best :D
You should do the Oxtools toothpick challenge with a bored hole and threads inside!
jan einar wold and a knurled finger grip!
Those boring bars in the video give you an idea of just how big Stefan and his shop are 😱
The shop is quite small - I am quite tall, haha :D
If I take anything away from this video, it's without a doubt the perfectly used Bob Ross quote.
I’m a big fan of your videos, and learn a lot from them. I’m a watchmaker working on very old pocket watches and use mainly a schaublin 70 and aciera f1. You mention in this video machining the shank of your new boing bar. I have a mt1 wolthaupter similar to yours that I want to change to 10 mm. I would like to see how you would do this using only your lathe/mill/dbit grinder (as these are the tools I have!)
Best regards
Stefan, thank you for this fascinating & educational video. Here's my vote for a video on ISO reamer specifications. Also, when you cut the slots with the 0.4mm slitting saw, how do you ensure that you get an "exact" depth of cut since slitting saws don't run particularly concentric with the spindle?
I approached the work very slowly with the saw blade rotating, until until I got the characteristic *crrrrrk* where the saw blade makes contact for a fraction of a second and considered that my zero position, thats good enough in this case.
The depth of the slot was not crazy close toleranced, its only for a springsteel clip.
If I needed it more precise, I would do a shallow cut, measure the depth and then correct to final depth.
Dude!
The amount of work you put into these parts, I hope you charge them accordingly!
Incredibly informative, Stefan. Thank you. I have been struggling with cheap insert tooling lately. Soft carbides. I had thrown together a cheap diamond lap with a Chinese 2000 grit diamond lap. It does a nice job lapping the dull inserts sharp again, but they dull very quickly... but, I have this stack of used carbide endmills piling up. I keep them with this zany idea that I’ll have them resharpened... I assure that’s not happening... I think it’s time to take your advise and make some new carbide tooling and holders!
Chinese inserts a a hit and miss - The ground ones for aluminium work usually quite well, with inserts for steel, I never had luck, they are probably made out of compressed street-dirt or something like that. When trying to put a edge on them, they just crumble apart.
Endmills are usually a very good grade carbide, fine grain and tough.
@@StefanGotteswinter - compressed street dirt.... !!
I like how you say "wörk".
A lesson about tolerances would be nice.
Love the round tool bits, Just drill a square block with the bit size, set screw, find the center of your grinding wheel hight use the table in machinery's handbook.To set the rest hight of your fixture and get the relief angle you want. just use a protractor to sharpie a mark on the rest or clamp a fence just feed straight in against the fence. you can rotate the block and grind another facet of your cutter. usually by reclamping the fence to a new angle but leaving the set screw on the block tight looking at the catalogs of ghuring and ifanger i learned a lot good to see you stefan
thank you Stefan, always learn a bunch
Thank you Stefan...learned and thoroughly enjoyed. -T
I didnt mind the length of video, rather enjoy, plus quit a few technique's i could use on some of my projects.
Thanx 4 sharing.......
'Sup, dawg; I heard you like collets.
Seriously, though; sticking a custom collet inside the standard collet is a great idea for holding tiny parts like that.
My guess would be that the price of the flux capacitors is about gram for gram equivalent with diamond.
Wonderful video - fascinating and instructive. I hope the 'reference snail' in the photo at the end is ISO compliant.
Thats definetly a metric ISO9001 compliant snail.
Thoroughly enjoyable.
I thought his "wife" was helping hold the part 😂😂
It was his "vice"!!!😂😂😂
Love this channel!!
Very interesting Stefan.
Hi Stefan, ejoyed watching your very intersting video, thanks for sharing.
Amazing Stefan ..like a a greetings from Brazil
Great video as always thank you sir
Thanks for taking the time to produce and explain the process. Great video work with closeups.
Work is on the other size end from Abom79 🙂
Can you tell about the magnifier you are using ? Looks very useful. My eyes are getting old
Thanks
Most of the time, I use my dads old 8x magnifier that he used when he worked in QC. I dont know about the manufacturer, but its very nice, with a metal housing.
Also nice are the small magnifiers from PEAK.
Maybe easier to get is this one:
www.optics-pro.com/watchmaker-s-loupe/schweizer-magnifying-glass-tech-line-10x-watchmaker-s-loupe/p,23346
Also very nice optics, real glas, no plastic lens.
Great video once again.. Thanks
