i hope this is in the correct area.

im looking at getting some ballscrews from ebay.
( link shows one i was looking at, but i need to make sure i get correct diameter and pitch ones for my lathe)

i want to replace the crap leadscrews on my lathe
as there is so much backlash

has anyone machined the ends them selfs before on a lathe.

are they easy to do. or are they hard as nails to machine.


cheers.
