I haven't been doing much watch wise, but lots of work on watch tools.

I ended up needing to make a bunch of parts for a lever action tailstock for a small Schaublin lathe.  I have the factory main casting and quill (the critical parts) but all the auxiliary bits are missing.  The lathe is a duplicate so fortunately I had a set of parts to copy from. 

First is the tailstock drawbar.  Toughest part was it’s a 11.75 mm metric buttress thread.  For those not familair, look at the collet; the flanks are 45 and 5 degrees vs every other thread that is symetrical.  It took longer messing about grinding the tool than cutting the thread, but it worked out well – its for a W12 collets

Next up, is the tailstock lever.  Not particularly difficult, but man, it was a lot of whittling!  Files and die grinder mostly after roughing to shape in the mill.  The turned portion I did by measuring the existing one, making grooves every ½” to the right depth, then roughing and finally finishing by hand turning.  I stuck the dull end of a 1” boring bar out in front of the work grabbed a large radius nose tool (maybe 1.5” radius, ½” tool bit) in a pair of vise grips and went at it as you would with a graver in a watchmakers lathe.

Paint is sprayed via airbrush, with talc in it to reduce the gloss.  In the last pic, I have some touch up to do….the quills were slightly different dia so I had to grind a bit out of the inside so it would fit.

Its watch tool related, but for a sure little different for this site so thought you might find it interesting....now back to the salt mine!

      Introduction

      By Randy55 · Posted

      Welcome to the group Stirky. You can search for just about every subject in the craft here. Don't be afraid to ask if you can't find the answer that may have already been covered ( some ad nauseum LOL ). You don't have to buy Bergeon to get good quality. There are many decent mid-range tools available that will last you a lifetime. Cousins would be a good place to start . Cheers from across the pond ! Randy

      What are these Seitz B-Jewels?

      By Jon · Posted

      I picked up a similar amount of these jewels some years ago in a watch and clock fair. Every now and then they come in handy. This week I've got a rubbed in bombe jewel in the balance cock that is cracked and needs replacing. Very handy to have a vintage assortment of these type of jewels!

      Diagram for 6497 motion works

      Great diagram with the teeth and pinion count. Simple way to reduce the speed of the hour wheel by the 12:1 minute wheel. Genius and yet so simple. Always good to reinforce the principal by what you have done in your drawing. Keep doing that. I had a drawing on my wall for years showing me this which is very similar to the drawing you have done. Here's a formula to work out the beats per hour of a watch movement. The movement's BPH is dictated by the wheel teeth and pinion count and the hairspring being vibrated to the correct BPH by finding the pinning up point on the hairspring using a vibrating tool.  The reason in the formula there is X2 on the top line is because there are two pallet stones.

      So I just wanted to say "thank you" again.  The angle is the key bit it seems and yes, it did basically just fall, or float, back into position when I got it lined up just right. I had meant to add that now that I see how it goes in, I totally see how it came out in the first place, and that whomever cloned the original movement didn't pay much attention to the fine details around the setting or how it interfaces with the balance cock or the "rings" on the regulator and/or stud carrier arms.
