Hi  I think its way over the top you are paying for the bergeon name there. I picked one up in the UK for £350 with cross slide,   ,bernard chuck,   drill attachment,   assortmet of collets and cutting tools all mounted with motor etc. Its  an American pattern and quite versatile.

    good score !    but,    some of the new members might not  know how to bid on the net.   I am one.    vin

How much of an issue do you think this is? Is it a deal breaker? I don’t want to train myself on something that is totally non-standard.  But that set does look great.

 

I would say enough of an issue to avoid it.

 

My recommendation would be a WW pattern lathe, often referred to as American style. Brands to look for are Boley, Boley-Leinen, Lorch, Wolf Jahn from Germany, Levin and Derbyshire from the states.

 

The Brits had a number of excellent makers too, but didn't produce as many as the Germans and Yanks. The Pultra you linked is a great machine, the only drawback is it takes 10mm collets which are harder to find than 8mm. On the other hand it is very complete and the price is fair. It's top quality and plug-and-play... and you always can sell it for the same money.

I agree with nickelsilver... keep away from 10 mm collet lathes. Look for 8 mm collet versions, as you'll find more collets of that size. 6 mm and 10 mm collets are like unicorn poo!

I have a WW type lathe, rather than a 'Geneva' type lathe, because it is versatile and can handle slightly bigger work, especially if I'm using a cross slide, but can cope with small stuff like re pivoting and pivot polishing etc.

The good thing about WW bed lathes is, they have great tail stocks that help with drilling, rather than Geneva type lathes that don't.

WW bed lathes also have a bigger clearance from the lathe bed, which is great especially using a face plate if I need to drill a hole in a watch mainplate to fit a new bush. I find them a lot more versatile, but that's just me.

I know it's a minefield when it comes to buying a lathe. Go with a WW bed like JD Richard owns. So much better in all respects.

If JD can't sort you out, I have one spare...

Here's a set you don't see very often Favorite Lathe

 

Yes, it's expensive, but it's very complete, and these are really good machines. I sold one about 15 years ago that didn't have the milling attachment, wheel chucks, the simple tailstock with pivot drilling discs and with a smaller set of collets for 2500 and that was a friend who bought it. It's pretty much exactly the same as a Schaublin 70, just smaller.

 

If you tried to piece together that set it would take possibly years, and possibly be more expensive.

 

I wouldn't say not to go for that Pultra. It's a really nice setup at a nice price. You've probably already tracked down the page on Tony Griffith's site, but here it is anyway Pultra.

You can see down the page an adapter for going from 10mm to 8mm, which Tony admits may have been shop made. If you got that Pultra, and were smitten with lathe work, it's likely you'd end up getting some other lathe down the line as well; as this is based on the WW pattern, while it's fairly certain tailstocks wouldn't interchange with another maker (the WW or Webster Whitcomb pattern was used more as a guideline than an absolute standard by most maker), the slide certainly will. It can be very handy to have two lathes at times.

 

Tony's site also has a for sale page, often with a number of interesting lathes for watchmaking listed.

In the UK there are plenty of lathes for sale on a regular basis. There's less WW-pattern ones, but there's nothing wrong with Geneva-pattern lathes. More importantly you want a headstock which turns smoothly with no excessive play.

While I'm a fan of the WW pattern, I agree that for most work a Geneva (bar bed) pattern is OK, many many watchmakers and even clockmakers have used them to great success over the last century.

 

Most, like easily 9 out of 10, headstocks one encounters use a hardened steel spindle running in hardened steel plain bearings. Hardened steel on hardened steel is a terrifically durable combination, if there is just a hint of oil there they are practically indestructable. And many lathes saw little actual use, so it's rare for a lathe from a quality maker would have messed up headstock bearings. What would be important to me, after the headstock, would be a tailstock that takes collets, and very importantly, an excellent cross slide with large, readable, settable micrometer thimbles on the cranks. 

 

Many older slides have tiny thimbles, that are not necessarily settable. If looking at Lorch, some of their old stuff not only had tiny thimbles, but had screws with 0.75mm pitch (as opposed to 1mm), and they were backwards in rotation from all other lathes. A fellow I worked for had one, it was his first lathe from when he was young and he loved it. I absolutely could not use it, my muscle memory just wouldn't allow me to turn the cranks correctly. Not to mention keeping track of 0.75mm per rotation! He had numerous other more modern lathes that were "normal", but man he loved that weird little Lorch.

 

All that said Lorch is of the highest quality and their more modern stuff was vastly improved in usability. Their KD 50 model is one of the nicest watchmaker lathes ever built. Steffen Pahlow's superb Youtube channel features many different Lorch machines in his work.

One thing I will also add, is that in the early days, you may not want to use a cross-slide at all. Not that you should avoid a set if it includes one! Most of the work I do is by hand. I don't want to have to set up a cross slide if I can hand grave in a matter of seconds.

Also, in my experience, cross slide work is better on a sturdier bed like a WW or something bigger like a Schaublin. I believe the reason is because you can (perhaps unintentionally) be applying significant pressure when using a cross slide which can cause unwanted movement due to play.

    • just one little minor reminder here this isn't your normal balance wheel.  pages 17 and 18 are what you really want to be looking at. normally studs don't turn but this watch has the etachron system designed for lots of adjustment. Personally I would try to rotate the stud back to where it's supposed to be. If you're lucky you didn't actually bend it at the stud it just looks really bad as the stud has been rotated grossly out of position.. I think things will look a lot better if you put the hairspring back where it's supposed to be by rotating the stud. it's hard to tell if you actually did bend it at the stud or not we won't know until you rotate the stud back more or less where it's supposed to be. Then you want to pay attention to the manual of how to put the hairspring back in the regulator pins because yes they rotate also and they rotated specific directions otherwise bad things will happen to your hairspring. so initially you can open up the regulator as wide as it can go and don't worry about closing it until thing everything is right then you can close them a little bit
    • I need to see photos of the whole movement before I comment. 
    • Hi @Jon, so, from one extreme to another the beat error is 0.1(min.pos) to 0.2(msx.pos), and as you mentioned the rate does up and down dramatically. Also checked the position of the collet, and the collet is not central to the jewel on the balance cock. Balance moves freely, per my understanding.   So, after 24h the ampl. fell down by approx 20 deg, which I would assume is expected. After adjusting the endshake I believe I gained around +10 deg. of balance movement. Which is great, and overall the balance is not at 220'ish deg.   What I did next, some might think is non-orthodox, but was wort a try. I too the mainspring out, checked again for endshake and if the pin moves freely, and cleaned everything. Usually when installing the mainspring I would use some barrel grease on the barrel walls, install the spring and put a 2-3 drops of D-5 oil on top of the wounded spring and in the places where the arbor sits. This time I took the spring and applied a ultra this coat of Molykote Dx paste on the whole spring, before installing it in to the barrel, and added some oil to the arbor as usual.  The result improved, at a full wound the balance produces about 230-237 deg. @JohnR725 I'm getting closer to 300 😃   What I am noticing, there is a fluctuation in amplitude. With time it would rise and drop about total 8-10 deg in an interval about 2 minutes. I assumed this ruled out the power transfer from the barrel itself. So I took the gear train out, cleaned and lubed. 
    • Thank you so much, Hector and CJ. I appreciate the tech sheet and the video. Gasp, I think I will make the attempt. What's the worst that can happen? I think there may be a new balance complete in my future, though.  I'll update the post and let you know the result. R, Frank  
    • So here is the new base (v 2.1), I made it so that the base will fit over and swallow the stump of the hand pusher tool (or at least my clone of the tool), I also reduced the OD of the bottom skirt a little as it looked/felt a little large, here are a few pictures and the fake .pdf file which you need to convert to .zip once downloaded.   The cut-out seen on the below image on the bottom of the base should swallow the OD (40 mm, +0.1 mm tolerance) of the stump and the height of the stump 9.5mm (measured to 9.1mm, but rounded to 9.5mm) - let me know if this works for your tool.   Note, I think you may need to print supports for the new internal shelf created? Here is the fake .pdf for just the FreeCAD base file and 3mf files Modular Movement Holder.pdf Here is the fake pdf for complete set of the new base and ring FreeCAD/3mf files: Modular Movement Holder base and ring v 2.1.pdf However, I'm wondering how often you could use this feature, adding the dial usually increases the OD of the movement, so you would need a new (larger) adapter ring tuned to the OD of the dial and I wouldn't like to grip the dial in any kind of movement holder if It could be avoided for fear of damaging it. Maybe I'm misunderstanding you?
