Hate to ask but does anyone have a Bulova Watchmaster? i thought i took pics of the inside before i dissembled the coils that run the cleaning cups i guess they are transducers, anyway cant remember the wiring and the wiring diagram doesnt show the coils that i can recognize, i had one of the coils actually burn through,after two capacitors blew, (bigfire!!) had to rewrap it, I can take pics of mine if that helps, but i need the shot of  top side under the shieled, the unit was marketed by Portescap  for a while after bulova went. ANYWAY thanks,

why don't you give us a picture of the diagram maybe we can make sense of it.

Found this which might help as it shows pics of a Bulova watch being tested.

wrong device similar name though unfortunately. The request is for a cleaning machine although I can see why there'd be a confusion I thought maybe this was a watch discussion until I read the text but I'm pretty sure it's a cleaning machine hopefully

the holes are where the cups fit into the transducer coils, the larger one i rewraped and matched the 1.4ohms. to the old burnt coil, this is the wiring diagram and i dont see where these are on the diagram? i set there for an hour looking at the terminal and realized the red coil wires solder to two different  switched lugs with the ends  going to two wires that are black and are a ground, i guess over the years the caps went, i plugged it in they blew and the i found the bottom coil was missing its shellac or whatever they coat it with i guess from spilling cleaner in the hole, and it burnt , or vice versa, the coil shorted taking outthe caps i amnot an electronics guy more of automotive wiring diagram repair i decided i am going to try it tommorrow with a fused power source, the circular lug under the tube are where the coil wires attach,this cleaner has worked since 1979  when i bought it new,thanks for you time and opinion.

    • I believe @nickelsilver has a setup like that.
    • I posted pictures earlier in this thread. My lathe and mill are two separate instruments. I think I have seen examples of putting a milling head on a lathe bed...but not certain.
    • Timex Camper, September 1994, new to me. Strap is an old perlon with "Germany" in script etched into the resin on the tail end. Not Horlon or Eulit I believe. History unknown, running strong, losing less than a minute a day. Goals for this: Wear it a ton! Buy crystal lift, clean out the gunk around the ring and under the crystal Eventually swap into a stainless steel case. I've seen a member who has swapped a Timex mechanical movement into the Timex J.Crew quartz field watch case.
    • One of the problems we would have with a watchmaker's lathe is they were made over considerable span of time and manufacturing in the early days probably wasn't as good as it was today. Then if you look at the older catalogs typically it was just the head a few collets and something to rest graver on. So basically a basic lathe with over time things acquired but acquired things may or may not fit. Order today you purchase a used lathe that all kinds of nifty bits and pieces from a seller that acquired from? This would come back to that the basic watchmaker's lathe was used for basic watchmaking like turning things with a hand graver. Then limited indexing is fine because you can make things like stems Which don't need a whole bunch indexing   In the link above the word vector is mentioned and at the link below you can purchase one. Then of course you're going to need the motor that's a little bit extra for the price. https://www.hswalsh.com/product/lathe-vector-watchmakers-48-collets-hl11. That you're going to need some bonus parts like these found this picture online show the classic way of classic gear cutting.   The lathe could have a much bigger indexing disk but it has to be mounted close to the edge. Otherwise you're going to have a whole bunch of smaller disks like this which I think has notches rather than holes. Then as wonderful as these pictures look actually cutting a gear with this is not entirely fun. Look at all is belts all pulling on things and this is a watchmaker's lathe lightweight with lots of bits and pieces attached. It would make more sense if you actually cut a gear with something like this and it tends to be it's not really the best way to do it looks nice on paper but it is not the best way to go. Reality for cutting watch parts would be a bigger machine is much better. Than getting rid of all those belts and pulleys also good. Here is an interesting channel I would've liked of found a different video but this was nice and short if you look at his video as he uses a stepping motor and worm gear assembly for the indexing plate. In this particular video it gets attached to the lathe at about one minute and seven seconds and it looks like it's hiding looks like he has a Sherline. I do know he's had other stuff you'll just have to go through his videos to find it. Then at about one minute and 22 seconds you find out if you set up things appropriately. It's always bad we end up with half a tooth at the very end. Then you will note big lathe yes he's getting a big gear but you could easily cut a watch gear with the setup. And it definitely way more stable than a watchmaker's lathe.         Oh here's a company they been in business since 1911 http://www.fwderbyshireinc.com/
