If you're interested in the variable speed brushless DC servo motor that I have attached to my vintage watchmaker's lathe that was a purchase on AliExpress and cost $98 not including shipping.
Here's an affiliate link for that:

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.

Hi Dayton- I’m always impressed with your studio set up! I love all the angles. Kudos to diving right in to screw making. It’s so satisfying, isn’t it? I’m glad you have the Martin screw plate. I learned the hard way that some of the modern plates are made of steel that’s just too soft. just some other tips from what ive learned as a beginner- The chattering you heard as turning is due to a combination of the graver being too long and the tool rest being set too far away from the work. If the graver can’t be slid further into the handle, you can try directing the force using your pointer finger as the handle is firmly planted in your palm. The tool post needs to be angled in the same direction as the work. So in your case, parallel to the bed. As you’ve discovered- If you’ve got everything setup correct (speed, graver sharpened, angle of attack, work piece soft enough, etc), you should see spirals/chips of material (swarf) steadily release from the work. I bet you noticed a sweet spot of how to angle and press to get the most effect. I highly recommend lowering the setup so you can plant your elbows to stabilize the graver. It will give you more control and prevent the graver from slipping off. Ensure you’re making contact in the center of the work when viewed from the side. It looks like the graver is cutting from the bottom and the tool post is being used as a fulcrum. That’s why the graver is getting sucked underneath. For that screw plate, I no longer try to measure the stock- instead I just iteratively turn it down until the work snugly slides into the next hole larger than the one you want to cut with. For smaller screws, look for a “screw head slotting file”. They come in various sizes. Finally, look up graver types. I think the one you were using is for “engraving”, which is a little different of an application. You can find carbide graver blanks on eBay that you can shape in the diamond pattern that DeanDK demonstrates in his videos. Best of luck to you and congratulations on successfully creating your first screw, and thanks for taking us with you on the journey!

Thanks Chris! Yes, the camera set-up on this second bench is something that I've been working on for a year. I jokingly called it Magnum (Zoolander reference) because it was never even close to being ready - until now! (Still needs some tweaking actually). Thanks for all the tips! Correct gravers are on the way and I think I'll do much better on the next try. I thought it would be interesting to get this first try on video even if I do look stupid (not sure why I wrote "if" 😂) because that's a fear that anyone thinking about doing this needs to confront. Thanks for your detailed advice and yes, making tiny non-standard vintage replacement parts that are unique and that you could never find a source for in a million years is very satisfying! The part may not seem to have much value to an outside observer, but the watch or tool that it brings back to life certainly does! Thanks again for all of your inspiring videos!

hi I fell on to your channel by chance, i have sub'd and bell'd you for future viewing i take my hat off to you for giving turning on the lathe a go with no experience, I don't use watchmakers lathes but use bigger lathes for my steam projects. Cutting metal successfully on any kind of machine is all down to the correct tool angles /geometry etc and having the tool on centre height and the correct approach angle and ridgity. Once you have conquered the correct tool geometry, you will find things much easier and quicker. all the best👍👍 regards Kev(UK)

Thanks Patrick! I really appreciate this comment. I have had many successes in my life and they all started out like this. I will also succeed at watchmaking. This is what success at anything looks like at the beginning. Some people seem to worry that by making mistakes on camera I'm teaching others to do the same. I guess that's a risk for the way that many of us consume media in short samples. I appreciate it that you took the time to look at the context.

@James-fs4rn 4 месяца назад

With how shiny the screw was when cutting I'd say the tool was too dull and rubbing. This could lead to work hardening the material thereby making it more difficult to cut. Look at metal cutting lathe bits for an example. A good honed cutting edge with proper relief should work. HSS is plenty good enough for the tool bits. More forgiving to chipping and easier to resharpen. Good luck.

@IShootWatches 4 месяца назад

Thanks for this comment, James! There was definitely an inordinate amount of rubbing going on and I didn't think about work hardening resulting from that. Thanks for mentioning it! I did order some new Vallorbe watchmaking gravers -- in both HSS and whatever the normal material is - and I'll be taking another stab at it (no pun intended) as soon as I receive them.

@DeDeNoM 4 месяца назад

I have very limited experience when it comes to turning on watchmakers laths, still here are some things I noticed: You have to careful about the tool height when turning. To me it looked like you sometimes had the tool ( cutting edge) below the workpiece, not on or even slightly the center line. This can cause rubbing and prevent you from efficiently cutting metal. The word graver can have slightly different meanings. It can refer to the tool used on a watchmaker lathe or the tool used for hand engraving (either with hammer and chisel/graver or hand push engraving). In all cases the graver is a hard and sharp piece of metal used to cut metal, but the exact geometry differs from application to application. That Vallorbe graver you bought looks like a hand engraver to me. Other than that I hope that you continue to enjoy your lathe. Messing around and cutting shapes into metal by hand is just a lot of fun. Especially in brass, as everything is shiny and gold and so much easier to work then steel.

@IShootWatches 4 месяца назад

Thanks @DeDeNoM! My goal is to make hardened steel balance staffs for ladies movements ASAP. I don't have time to mess around with brass! 😂😂😂 I'm kind of joking, kind of not joking - I still have my IWC Cal 44 balance staff replacement to do and I broke one of the three new balance staffs I bought for it already. I'm really curious how it feels getting down into that much smaller world than this screw.

@mrimmortal1579 2 месяца назад

⁠⁠@@IShootWatches ⁠ You’re off to a good start. Ok, ok, you’re off to a start. lol The geometry of the tip of your graver is the important part when cutting metal on a lathe, along with having the cutting edge of your tool at the right height (usually on the centerline of the spinning part). I highly recommend that you check out some of the videos from a RU-vidr called ThisOldTony. He has a great way of explaining things in a way that makes it all make sense and is easy to understand (plus he’s funny as hell, in a weird sort of way). While he’s not about watchmaking, and his machines are much larger than a watchmaker’s lathe, many of the concepts are transferable. Another very good channel to check out for info on working with small lathes and different types of metal preparation before and after working them is Clickspring, and a third would be Blondihacks. As the above poster mentioned, you want to be supporting the graver much closer to the workpiece. You shouldn’t need to put much pressure on the tool, the cutting edge should be doing all of the work. And for god’s sakes, any time you are loosening or tightening your tool post, SET THE GRAVER DOWN!! One slip with that thing, and it’ll slice you a new one! Also, you shouldn’t need to put much pressure on the screw plate to get your threads started. Put a slight chamfer on the end of the screw to help get the threads started. The good news here is that you’ve successfully cut your first screw! A *BIG* congratulations is in order for that! It was truly cringeworthy to watch, but in the end you wound up with a useable screw and didn’t get blood all over the place, so that can be considered a win! What you said at the end was correct: each one you do from here on will be better than the last. Keep up the good work!

@mrimmortal1579 2 месяца назад

I don’t know if it will let me paste a link, but the specific ThisOldTony video that I was thinking of is ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-__A2xtLF0AU.htmlsi=naZ1eR21v4h9LakL If I remember correctly from that video, there are some very helpful graphics included that show the relationship between the cutting geometry and the workpiece, and how they affect the way the metal cuts.

Hey, that stem I "made" is still usable (albeit in the original watch it was made for!) 😂😂😂 I can't wait to get back to that, by the way, I ordered some proper watchmaker's gravers and read / realized that for those tiny parts you need A) better skills and practice, B) super sharp gravers, and C) high spindle speeds (because the surface of a 0.35mm cylinder is moving a lot slower than the surface of a 4mm cylinder at the same RPMs.) I should do the math on how much slower but it's Sunday and I'm lazy and I'd probably get it wrong anyway.😂😂😂

Do all watchmakers lathes use the manual tool rest style of turning versus having a fixed cutting tool (tool post) and longitudinal and cross feeds like on their bigger brothers/full size metal lathes??

*I know zero about watchmakers lathe work but quite a bit about normal metal lathe work. To me it seems you'd do alot better with a tool holder rather than a hand held cutter.* Tool height and center line are crucial down to ridiculous levels on a normal metal lathe, I'm sure they also apply to WM lathes. It's hard to tell from me viewing the screen, but RPMs are crucial as well. You can't be in a hurry either! 🙂

@IShootWatches 4 месяца назад

Thanks for this comment! Yeah, I would love to have a cross slide now! Also I do realizes (but it doesn't hurt to reiterate) that the RPMs, especially on very tiny diameters, are important. My motor does go up to 5000 RPM, and I can use the belt and pulleys to bring that number up even higher. I'm really excited to get back to the winding stem and then eventually balance staffs. It's insane how small the pivots on balance staffs are and that they were once (and sometimes still are) made by hand!

Thanks again for your comments and advice, Sonny! Diamond sharpening plates and a tool holder for sharpening are forthcoming but in the meantime I upgraded my graver purchasing process! Factory new Glardon Vallorbe LO 0501 and LO 0502 gravers are on the way. These are the two gravers that Vallorbe makes for watchmaking: diamond tip or square tip - made in sizes ranging from 1.5mm to 5mm in either hardened steel or high speed steel. I felt it was important to compare anything I sharpen with new gravers as a benchmark. I also picked up a meter of 3mm brass rod to practice with. For anyone that hasn't read the other comments, the new Glardon Vallorbe knife-style graver that I used in this video is made for hand engraving, not for the watchmaker's lathe.

Your graver ground angles are wrong. It looked like the front clearance angle was zero ( square to top of cutter). I use an engine lathe with HSS cutter. Front clearance 7-8 degrees, with a positive rake about 12 degrees for annealed silver steel. Today I cut a pin .016” diameter from .125” stock in a single pass, (remember to pull tool back before returning to the right or the pin climbs the tool) then polished to .015” with 400 grit paper then with 1200 grit. If you cut brass top rake is zero, and you can reduce front clearance, ( but I don’t). 38:30

I like to joke about getting hurt while also taking safety seriously. I briefly worked with Mark Pauline of Survival Research Labs in New York in the 1980s who lost four of his fingers messing around with rockets and had toes grafted on in place of his fingers (not sure if they were his toes or someone else's). I also worked on a project in Nice on which a rack of 100 Martin follow spots 40 feet high on scaffolding with metal wheels rolled over a crew members foot and turned it into a smoothie. One of the reasons I chose to learn watchmaking at this advanced age is to not have to worry about blowing myself up, losing digits or limbs or falling to my death. Nevertheless, safety should always come first, even in watchmaking! 😂😂😂

Seems like you need to sharp your graver

@IShootWatches 17 дней назад

Yes! I learned me lesson on this one! The difficult thing was coming up with a good solution for sharpening. I now have a larger lathe with diamond plate grinding wheels (as well as regular grinding wheels) that make sharpening fast and easy. Just have to not go so fast that the graver gets too hot and loses its temper.

@Roelasia 4 месяца назад

I saw one other video from you, your lathe needs some adjustments and has a lot of axial play. ""Making a Stem" 😂 for a Patek Philippe 16-250 with my New Lathe"

@IShootWatches 4 месяца назад

Yes, thanks! Other viewers informed me of that and I tightened it up in the subsequent video in which I lubricated it and tightened the cone bearing without completely disassembling the bearing. I will completely disassemble clean and relubricate it in a follow-up video. I didn't want to break it so I waited for user comments and found some detailed videos about disassembly / reassembly. In any case thank you for this comment! The comments on many of my videos are at least as important as the videos because my mistakes and user comments reveal details that otherwise are seldom discussed in RU-vid videos and even more rarely shown visually.

Need some lubricant when cutting those threads - it will be easier and your thread plate will last longer. Get some tapping oil - don't need much!

@IShootWatches 4 месяца назад

Isn't that what I was using? (I used TapMagic)

@johnhinkey5336 4 месяца назад

@@IShootWatches Sorry, maybe I missed you applying tapping oil to the thread plate. If you did then great!

@IShootWatches 4 месяца назад

@@johnhinkey5336 I applied it generously to the tip of the workpiece not the plate. But in any case using tapping oil is still good advice (and a must as I understand it) for anyone reading the comments. I should have applied it to both the workpiece and the plate. Next time I will!

@@jonathanforget8988 Yeah, I've only lived in Geneva for 25 years. Maybe if I decide to settle down here I'll try to learn the language! 😂😂😂 I was at the lake with my daughter before she could even walk, so when she was around one year old, and I said, "Regarde l'oiseau, Mila !" and she snapped back at me (in English): "Actually, that's a DUCK, Dad!" I will remember that forever because she used the word "actually" and then I had to carry her back to the house after being shamed like that because she was literally still too young to walk. Anyway, that totally shamed me and I've never recovered! I still have no idea how to say "actually" in French. I think I usually say "actualment" because that sounds French to me but I just googled that and it means "currently". I did finally stop calling my wife mon mari however, after a friend told me that he didn't know that I was gay! 😂😂😂

@@IShootWatches that's hilarious. I mean you weren't technically wrong, a duck is a bird :P I would probably translate Actually to 'En Fait' .

Lol I've had many of those and sometime you only realize you have one a couple days later .. good times. keep on learnin!

@TheJame951 4 месяца назад

dude i admire the effort but those gravers you are using are for hand engraving. the geometry of the tool is completely upside down to the one needed on a lathe. you were rubbing away he material at all time instead of cutting it. I was in terror, praying all the time that you wouldn't hurt yourself, while watching the video. Please, even if you are in hurry do more research and spend a little time informing yourself before messing with machinery, your safety is worth more than a screw.

@IShootWatches 4 месяца назад

Thanks for this word of caution! I can’t agree strongly enough! I’ve ordered some proper gravers for my next video!

Bonjour de France je suis vos réparations de montre régulièrement je regarde le tournage sur tour et je crois que votre outillage est mal adapté utilisé et surtout vous ne maîtrisez pas l’affutage de vos outils et vous pourriez vous blaisser car tourner le métal doit se faire en douceur et avec un lubrifiant la hauteur de coupe de l’outil doit doit être a zéro et perpendiculaire à la pièce ce n’est pas du grattage revoyez les bases de l’art du tourneur bonne continuation😅❤❤❤ Gilles

@IShootWatches Месяц назад

Merci Gilles! J'ai trouvé intéressant de faire des vidéos "pour la première fois" pour montrer aux spectateurs ce qui est possible sans expérience ni formation. Grâce aux commentaires de téléspectateurs comme vous et à des recherches et pratiques supplémentaires, je vais beaucoup mieux ! Continuez à regarder pour voir mes améliorations !
