I have a Delta/Rockwell 14" lathe with QC gear box and variable speed drive. I would like to be able to cut metric threads but don't know if it is possible on my lathe. It has a 16 (or 32) tooth stud gear, two 45 tooth idler gears meshing with a 32 tooth gear on the screw. I'm a newbie home shop machinist, so I need lots of help. Thanks in advance for any that you can provide.
