    Attached are the measurements I took.

    I have a 9" 4 jaw that I'm looking to mount, I figured I could do the final fitting. @hvnlymachining let me know what else you need.

    WTB 3.5x4 tpi Lathe Chuck or Backplate

    My lathe is dead in the water until I can find a threaded chuck or backplate.

    3.5" x 4tpi.

    If you know of someone that could make a backplate let me know, I'm willing to pay for the work.

    Noted. Do you or anyone else know if it's common to rethread massive thread like this down to a more common modern pitch? Looks like 2-1/4-8 is fairly easy to get ahold of.
