I have a 10" Standard Modern Utilathe. The crossfeed and compound are both metric, and I would like to replace them with imperial screws & dials as that is what I am used to. (The longitudinal screw and threading gears are already imperial).
The sketch below is what the crossfeed screw looks like. The screw diameter is actually 1/2" but the pitch is 2.5mm.
I believe the imperial version of these lathes use 8tpi (.125" per revolution) screws, but I am going to go with 10. I have ordered a 1/2-10 LH ACME rod from McMaster Carr. I plan on turning the left section separately and mating it with a section of the threaded rod. My question is, what is the best way to mate the two parts while keeping them perfectly in line?
I was thinking I would drill/ream the right end of the left section, and turn a "tang" on the screw for a light press fit, as seen below. Either epoxy them together or weld the seem.
Any thoughts or suggestions??
The compound screw is short enough that I figured I would just turn it all from one piece.
Thanks
