Another Pultra question.

Can any body tell me:-

What thread is used on the spindle nose of the 8mm P type Pultra lathe?

Sorry, Ken ... was not aware that it had a threaded spindle.

As far as I can measure it, it appears to be 22mm x 1mm pitch.

Offering up an M6 machine screw to the spindle nose (or a thread gauge) would be an easy way to confirm the pitch.

22 x 1 mm looks awfully close to the 7/8" x 26 on the 10mm collet 1750/1770 lathes...
