I'm in search of a replacement lead screw for a Clausing 6300 lathe that I'm rebuilding. This one is usable...just barely. It is severely worn and SHOULD be replaced.
Clausing Service Center has one, but the price is...well, I paid half that much for the whole lathe!
To complicate matters, this is NOT a standard pitch for its diameter, and I can't find suitable lead screw blanks from any of the usual sources. I haven't found them ANYWHERE yet, actually.
The lead screw is acme thread pattern, of course, and it's 7/8ths inch in diameter, but rather than the normal 6 TPI, it's 8 TPI.
I need to see if someone can turn out a lead screw blank for me in this size, 7/8ths-8TPI, acme, and about 5 feet long, in decent steel.
Once I have the blank, I can handle the rest of the machining. But there's just no way that my only usable lathe (a tiny Smithy) is going to be able to make a five foot lead screw that's worth anything!
