- This is my first time ever using a watchmaker's lathe.
If you're interested in the variable speed brushless DC servo motor that I have attached to it that was a purchase on AliExpress and cost an additional $98 not including shipping. Here's an affiliate link for that:
s.click.aliexpress.com/e/_DkL...
I bought the 800W Kit, which includes the motor bracket.
I also bought the two v-belt pulleys you can see mounted on the motor's 14mm shaft separately:
smaller pulley (mounted closer to the motor in the video):
s.click.aliexpress.com/e/_DD2... (select W4 O30 suit 4mm belt and specify bore size of 14mm to seller in message)
larger pulley (mounted on the end of the drive shaft in the video):
s.click.aliexpress.com/e/_De0... (select Bore Diameter: 14mm, Width: 40mm)
You only need one pulley, and I recommend the smaller one even though it costs a bit more as it fits the 4mm belts better. I ordered two because I was not sure that the larger, less expensive one would work. It works fine but the belt can slip from side to side.

That’s a really nice setup! I’m impressed with the microscope and monitor you have mounted. By the way, I learned a lot of what I know about hand turning from Archie Perkins’ book and from Dean DK’s UA-cam channel.
Here are some tips I learned as a beginner lathe user over the past year-
Turn under 1000 rpm, the slower the better. You should be able to just barely visually see the steel turning. 600ish is good. If it’s too fast, the graver will sort of skip over the surface and have a burnishing effect.
Lower the overall setup. I find I have better leverage with it chest height and that also allows me to rest my elbow on the bench for stability.
Keep the tool rest parallel to the work, and as close as possible. Perhaps a millimeter gap when viewed from above. But that will vary. Too large a gap may cause the graver to get pulled under the work, which tends to happen more with the tiny stuff.
Your graver should be sharpened up so the diamond is completely flat. You can turn the work either diamond up or diamond down, as a matter of preference.
The headstock/tailstock alignment test can be done with a razor blade being held between two dead centers. If the blade is straight up and down/front and back, then it’s aligned. I wouldn’t depend on a collet hole for the test.
Excited to see the progression with the new tool. :)
Thanks Chris! I'll try all of these tips! I remember the razor blade test from your lathe video but I knew mine was too far off to even try that. Looking forward to seeing a video about your new rounding up tool!
Hi Dayton, this series on lathes is super helpful. I'm considering upping my watchmaking game and your long form videos really illustrate everything. Thanks and keep up the good work!
Thanks!
I love the new set up! Great camera angles and explanations… You are going to have so much fun making metal chips and curly-cues! Nice selection of Watches in the encore footage, too. 😁👍🏼
Thanks Mike! Yeah, I'm thrilled about this one! It also justifies the whole Magnum / Bodenmann / Rolex service bench set-up! Gotta love how one bargain purchase in watchmaking can be used to justify the next one! 😂😂😂
Cool to watch someone "feeling their way" with a new tool...
Thanks for your comments! I just made my first screw on the lathe and will post that video shortly. I appreciate your support!
oei oei oei very nice Lathe Dayton all the stuff with it watchmakers dream ! have fun practicing....fun fun fun haha.. the wathes are awesome wauw !
Thanks Elder Pinto!
@@IMakeWatches i orderd a veisgrip 3 times two times lost and now there is again a problem with the order omg i need a veisgrip do you have this kind of problems
A minor point of clarification. Collet is pronounced kaa-luht. That's the phonetic spelling. I'm coming from a world of machining where the term is used constantly so I thought I would just mention. Great content, very cool lathe. Machining metal is an awesome skill to have and lots of satisfaction and feeling of accomplishment.
Thanks Paul! I'll check how the French pronounce it over here in Switzerland and will report back! Meanwhile, I already made my follow-up video so don't be offended if it appears that I continue to mis-pronounce it!😂😂😂
The French say co-lay, but I'm going with your pronunciation!
@@IMakeWatches Well, as they say, when in Rome... The more I think about it the more sofisticated it sounds. I just won't pronounce it around my machinist buddies. ha ha
@@PaulMorley1 Your pronunciation looks very American to me. In the UK we say Koh-let. Some regional tinges but certainly not Kaa. Since I think the word is French in origin we are probably all saying it 'wrong'.
Absolutely terrific, looking forward to seeing you get to grips with it.
I would consider putting the centre that you have in the tailstock in the headstock and turning it true before using it to test the alignment of headstock and tailstock.
@@digbethcustard Thanks! I'll do that!
I'M ALWAYS WATCHING YOU ~ well done ~
amazing video
Thanks!
Wow. thats an amazing filming setup. Im blown away.
Hi Sonny! I forgot to put SD cards in two of the cameras so you ain't seen nothin' yet! 😂😂😂
Great collection you got their at the end
Thanks! Yeah, that specific lot of five watches revitalized my interest in sub $20 watches! Other buyers see "quartz" in the listing and click away but those transitional hybrid quartz movements are super interesting and I'll be getting into that in detail soon. 😀
drawbar pulls collet into the head stock
Wow! I'm going to have to look into that! Can it also be used as a pusher in the tailstock? I'm still mystified about most of the accessories but also excited to learn more about them and try each of them out!
well done i feel your excitment
Thanks! Yes it's a never-ending rabbit hole of a hobby! I love it!
And yes its crazy and awesome
you need a board or an aluminum base for lathe and motor
Clamp works fine. On this bench the Bergeon clamp is mounted to the bench, so the motor was traditionally mounted further back on the bench. I may move my motor back as well but will likely keep it on a separate plate so that I can remove it easily when the lathe is not in play and not put drill holes in my nice benchtop!
Nice setup you need to get your tool rest back and straight to what your turning . and raise it up to much tool hanging out in front of rest.. have fun learning..
Thanks for your comment George! Yes, I was only trying to test the lathe and do my best from memory of watching other videos. Additional study and practice needed now! 😀
look at your lathe tailstock. i think i saw screws. they may ajust alignment
You’re right, those screws should give you a small amount of gib adjustment. If the screws don’t get it he could always try a bit of shim stock to get it aligned.
@@markclelland3510 Ive skipped on this design of lathe myself but they are interesting. i figured they would have alignment issues due to wear since the parts slide over and around rod.
That lathe set was an awesome find for just over $300.00. Some of the better lathes like the Wolf Jahn will have a serial number on each component. Check to see if all of the parts, (Headstock, Bed, Tailstock) have the same number stamped on them. If so, that will most likely ensure that perfect alignment can be achieved, because you can be sure the it was perfect when it left the factory as the original set. Oh, and for the love of God man, sharpen that graver. Pick up a Bergeon 2462 and a good stone. Just prepare yourself for a little bit of sticker shock.
Thanks for your comment! I did get some stones and inexpensive sharpening jigs and about eight more gravers in various lots of vintage tools (plus a few brand new ones). Eventually I hope to find a used 2462 or similar.
@@IMakeWatches I would recommend you watch Stephan Gotteswinter - slowspeed carbide grinder. He does larger scale than watches but he still works with great precision and care. And sharp is sharp.
Did you buy that motor separately? What motor and controller is it?
Thanks for your question! I just added the info about the motor to the video description. It was ~ US$100 for the 800W motor and bracket, and another $10 - 20 for the pulley wheels. The links are now in the video description.
@@IMakeWatches thankx for sharing
The tools need to be very, very sharp. Your microscope setup shows the contact really well... It looked, to me, that you had the tool upside down, we should see the flat part from the top view. You might need to raise the tool rest, so that the tool approaches the work at close to 90°/flat... There's a nice little series of basics here

have fun! a lathe is pretty magical
also clickspring..
Thanks! Yes, I've watched that Dean DK video. Need to review it again now that I have some hands-on knowledge! About clickspring, I lost the clickspring in the first watch I worked on and spent almost three hours making a new one. That was how I first discovered the joy of watchmaking! 😂😂😂
I also saw the same thing, with the tool upside down but that's okay because the lathe is turning clockwise and the most common thing is to do it counterclockwise.
About sharpening the tool is true, it is necessary and the angle depends on the material cutted.
You have to use the tip part and that curved shape with such a large angle is not suitable for hard materials.
You need to sharpen graver
Thanks! Yes, I figured that out and went overboard buying sharpeners and more gravers! I think I've got it now!
No Please! Sharpen that tool, it already looks like a file. Jajaja
I did! Thanks!
its spelled wolf und jahn ! not wulf tschaaan
Yawn.... 😂😂😂
@@IMakeWatches its IIIIAAAANNN! i try to teach you valuable german language skills here ;)
