Re: got my lathe ..now need help!
Congrats. You should be able to buy a spur drive that will clamp into the Nova drive. as Far as a drill chuck for it. Look into alternate Manufacturers. Many manufacturers have standardized on the thread pattern that the drive is on. You could probably get a chuck from Jet or a competitor that will fit your machine.
If it is in fact set up currently for metal You may want to look into the RPM levels on it. I believe metal lathes turn a bit slower than most wood lathes. I am not positive but I believe that is the case.
