AK Steel, where I am retired from had a duplicating machine in the rigger shop and all you needed was an outline of the part and all you had to do was punch in how many you wanted. It would copy/cut any number you wanted as long as the plate of steel that you were cutting from was big enough to contain that many pieces. Then the torch would cut them all out to any thickness you wanted.......Norm Abrams on NEW YANKEE WORKSHOP has the woodcutting lathe that you are talking about. You just make a template of the table leg (or whatever) you want to duplicate and it traces the template and copies the part. Like a machine that copies keys at the hardware store. Good luck.
