Recommendation For Watchmaker Lathe


bobm12

Recommended Posts

Hi everyone,

 

I know nothing about watchmaker's lathes -- although I have worked on regular, vintage ones -- and I'm looking for a recommendation and as much information one them. The goal is to get one in the very, very near future. Please help!

 

PS. I'll also appreciate information about compatibility of parts/tools for them. Thank you in advance.

Hi Bob,

Make sure that you buy a watchmakers and not a small modelmakers lathe. There are a few good makes to choose from, Boley, Lorch, Levin, Pultra and Rolls Royce of lathes Schaublin. Whatever you go for make sure that it is in excellent condition and with as many collets and attachments as possible. The reason I say this is to purchase the attachment separately will cost a lot of money.

Lathes such as Unimat are excellent for modelmakers, but do not have such a comprehensive selection of collets and attachments that you will require for doing watch repairs.

I have a Boley Lienen WW bed lathe and attachments. If you check out this http://lathes.co.uk/leinentradwatchmaker/ and http://www.lathes.co.uk/leinenmodern/ you will get some idea of the sort of things available. If you go to the homepage of the link, you will be able to look up information on just about any lathe, both large and small.

Went there and...found lots of things I wasn't counting on. It is so complicated I'm not sure if I should buy it now. Maybe later when I understand more about watchmaking...considering it is a substantial investment and my space is limited. but I still would like the most information about it as possible so I'll keep getting into it little by little.

 

Thanks Geo, those were excellent links.

Hi Bob, if you're buying new, look for a vendor near you, they can provide valuable guidance. You will also be needing tool steel and raw stock and these guys will be able to put you in touch with the right people (if they don't stock it themselves). They also supply stuff like cutting fluid etc.

Anyone know of anyone selling one. Am looking on ebay but nothing at the moment takes my fancy.  Looking for something heavily armed with attachments for drilling and pivot work. 

 

Having sold my larger lathe im looking for a 8mm to focus on balance work (well attempt it anyway)

 

was looking at the chinese lathes which i have heard are quite good but need some refinishing but would like to look for a swiss one before i look down that avenue.

 

Many thanks

Jonathan

Hi Jonathan,I bought my 'Star' on eBay, had to wait quite a while before a good one turned up (no pun intended)a BTM was also on my short list but the Star came along first,I was fortunate enough to go on a short course 'Introduction to the watchmakers lathe' at EFHC by John Hatt and he was an advocate of the Star lathe ,think Cousins have new ones listed so as a company they are still going, must say I'm very pleased with my purchase.

Be patient,ask the seller for extra pics and ask questions.

There are some good books out there on the subject by :

H.Jendritzki

Archie Perkins

George Daniels

Mick Watters

Donald Dr Carle

Good luck

You will be pleased for sure. For the price they are a bargain the only issue is how long they last but that is a unknown quantity.

BobM12,

The biggest problem with most watchmaker lathes is that most of the companies that manufactured them are no longer in business. This means that finding quality accessories can be a bit of a problem. Eight millimeter collets are still manufactured but six millimeter collets are not. There are a number of used Wolf-Jahn and lorch 6mm lathes available for a reasonable price but finding collets for them can be a matter of blind luck. To the best of my knowledge the only companies who manufactured watchmaker lathes in the past that are still in business are LEVIN, DERBYSHIRE, STAR and DIXIE (marketed under the BERGEON name. I don't know how long the SINCERE brand has been out there but they currently make a high quality lathe. Both DERBYSHIRE and LEVIN have shifted over to a slightly larger instrument size lathe but the precision and quality of these machines is so fantastic (20-50 millionths of an inch spindle runout),  they can certainly be used to make watch parts. As a matter of note both of these machines use ultra precision ball bearing headstocks while the Star, Dixie (Bergeon) and Sincere use the old fashioned cone bearings. While cone bearings are not as accurate as ABEC 7 OR ABEC 9 ball bearings, they have enough accuracy to make suitable watch parts. 

This brings the selection down to availability and affordability. Any of these five currently manufactured lathes can make suitable quality watch parts. Out of the five the Sincere lathe is the most affordable as are its accessories.

As an example a  Sincere milling attachment is less than $400.00 while a Bergeon milling attachment is around $7000.00. Both milling attachments are light duty accessories that lead to deflection problems under a cutter load. A 175 pound Harbor Freight (CENTRAL MACHINERY) bench top mini mill (once tweaked in and adjusted) will cut better than a watchmaker lathe milling attachment. The mini mill has more size, mass and power than the watchmaker lathe accessory, so the cutter is more likely to go where you want it to go.

If I were to give a recommendation it would be to stay away from machines with  aluminum beds. Aluminum headstocks are stable but aluminum beds can cause deflection and/or wear problems.  This is true for lathes but especially true for milling machines. Aluminum is not as rigid as steel and tends to bend more easily under a load. Cone bearings are OK but you have to learn how to clean and adjust them. You also have  to run them at lower speeds. Modern ball bearings are more accurate to several magnitudes and can run much faster than cone bearings.  

Just thought I would throw in my 2 cents worth.

JDM,

The Sincere is also marketed by a German company under the name VECTOR. The VECTOR comes in a beautiful wooden box and the SINCERE comes in a cardboard box packed in foam. The VECTOR costs a lot more than the SINCERE but does not have the advertising stigma of "made in China" attached to it. Other than that, once they are set up and adjusted properly, both machines can make good parts. 

A few years ago I read an article on the NAWCC web page written by someone who purchased a HORIA  Lathe. Apparently he paid a lot of money for the machine, but unfortunately,  the tailstock did not line up with the spindle. He shipped it back to Horia and they shipped it back to him with the same problem. In short, he was stuck with an expensive designer label machine that did not function properly.  I do not own a Horia lathe but I do own a set of Horia turns and they seem to work properly.  I believe that the most important aspect in a machine is that it functions properly for the job at hand or it does not. Trying to select a machine based on its brand name can sometimes lead to a bad place. If you are unable to fix the problem you just may end up with an expensive door stop.

PS:   I failed to mention the HORIA LATHE because I forgot about it. This means that there are 6 companies that currently manufacture watchmaker lathes.

a milling machine is more important than the lathe, for general use.

That's a sweeping statement that I don't agree with Vinn.  It very much depends on what you intend making or repairing.

David, what are "turns"? There are a lot of terms in machining which I don't know (English is not even my language). I've lost my chance to learn it when i dropped out of professional school, but that saved my sanity. I still want to make or repair parts, perhaps I should switch to clockmaking and do with one of these toy lathes I mentioned in another thread :)

    • 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?

    • Hi Frank, you have dived headlong into the deep end. Hairspring work has to be the scariest thing a newbie has to tackle. Your hairspring appears to be bent and just putting it back into the regulator would not allow the balance to work properly. It might start oscillating but the performance would not be good. The proper thing to do is to unstud the hairspring, remove the hairspring from the balance, reinstall the hairspring on the stud carrier, reshape the endcurve and centre the collet to the balance jewel hole. This challenge would either make you or break you. Hope that you will be able to fix your watch. Welcome to the world of watchmaking.  Watch this video. It think it'll give you an idea of the task ahead. From your 1st photo, I think you have a etachron type stud. Let me see if I can find a video on how to remove it from the arm.
    • Have read of the Tech Sheet attached on the balance section page 12. It may be bent but until you reposition it back in the regulator pins you'll never know. Cheers CJ 4R35B_4R36A.pdf
    • Aloha All, My Seiko 4R35B movement stopped working today. Upon closer inspection, it looks like the balance spring came out of the regulator pin. This is my first time working on a balance. Any advice on how to get this spring repositioned (back to normal)? I'm pretty sure that while adjusting the beat error on this movement, I must have turned the stud (I didn't even know they turned), and the spring eventually fell out.  Will the spring go back to even spacing when it's back in the pin, or does it look bent? Thanks, Frank  
    • Good job, that band matches the watch perfectly.
