Hi All

I'm still a beginner.  See the red circled part below the link.  The parts sheet calls this "Foil for coupling pinion".  The wheel is the "coupling wheel"  The mainspring popped as I lifted the plate and I was unable to see how the foil is to be positioned.  Any ideas?

Parts 2572 "spring for date correction" and 2539 "guide lever for date correction" are missing.  Those are shown on a diagram in this 2018 thread.  BTW, I'd love to get all those sheets if anyone has them.  Would variants of this movement be made without those parts?  

Thanks!

Charlie

That's the 'foil for coupling pinion' associated with the 'coupling wheel'. I've done my best Picasso on your pic to try and indicate where it goes. Place the foil first as the wheel should go on top.

Movements from the same family in general have the same base parts ... just additional parts to deal with additional, or different, capabilities. You might find this document useful too:

That's great!  Thanks much! 

I see, the foil appears to be a friction-adding device.   Thanks too for the service sheets.

    • Agreed, this is puzzling. Can you ask questions or inspect the lots before bidding? My Boley & Leinen Reform face plate is dia. 95mm exactly. It's possible that 4 inches is a slightly too large approximation, but why then make the distinction to 3 11/16 for the sake of 8mm? If the larger ones are truly 4" then they will clash with the bed, but then I have no idea which 8mm lathe would take them. All 8mm lathes have spindle height 50mm or less, as far as I know. The spindle height is, as you say, standard 50mm for W.W.
    • I have only been a member for six years & I have found this a very friendly forum although I don’t have anything to do with watches not because I don’t like watches but because I have gout in both hands so my dexterity isn’t very good, I restore torsion clocks & occasionally other antique clocks also at 72 my eyes are not what they used to be, that is why I only post on the clock forum & the lathe forum mostly . As others have said Mark it is much appreciated that  you are willing & able to do this. very many Thanks Dell
    • Ah, this is brilliant, thank you very much!
    • A local machinery auction this week is liquidating some watchmaker's equipment. Actually a truly absurd amount of it, from a machine collector's estate, making me wish I had waited a couple of months to buy my lathe because there are so many options at low prices. Anyway - there are a handful of faceplates on 8mm collet mounts up for sale and I think I can probably get one. Having never had one in hand, they seem kind of large as described though - all are listed at either 4in (101mm) or 3 11/16in (93.7mm) diameter. As I understand it, WW lathes are 50mm from spindle center to bed so it seems like the 4 inch faceplates would not have enough clearance. Could I expect the 3 11/16in to fit with a WW headstock and bed? What is a typical diameter for a faceplate? Also possible the description of "4 inches" is only a rough estimate by the auction house and not actually accurate. Example the 3 11/16": I may have answered part of this - a lot of the listings on ebay from typical American lathe tool makers are specify about 3.75 inch diameters. Still I don't see any that specify 4 inches, but I am still guessing that is an overestimate by the auction broker.
