Two Lathe Sunday

Stage 1: Start off by bringing out my Unimat SL 1000 Lathe to first turn down the 4mm stainless steel rod to 2.5mm at length of 11.5mm.

Stage 2: Turn down to 2.mm for a length of 10.5mm, check that the pusher fits into the fly-back pendant tube, which it does snugly.

Stage 3: 3mm of the end of work turn down to 1.7mm for the tapping the thread for the crown.

Stage 4: Tap the (No17) thread with threading plate and check the crown fits correctly.

Stage 5: Turn the workaround in the chuck and part off.

Time to get out of its box is my vintage G. Boley "Bevelled-bed" Branded "Telco", T.C. & M. Ltd

 6.5mm watchmakers lathe.

I needed this lathe so I could use the file rest and also set spring-loaded indent arm to lock the spindle.

Filed a Screw slot using a number 6 cut slotting file, now time to see if my manufactured pusher works,

So time to fit it in the watch case and then temporary replace the movement, and all works well.

Time to clear up the workshop and put the lathes away and set the bench for completing the stopwatch tomorrow!
