I became a proud owner of 10" x 38" old Sheldon. There is no serial number, just a small riveted metal plate with number 21 stamped on it. The machine works, but it needs cleaning and re-adjustments. I've some experience with China lathes removing and adjusting the cross slide, but cannot figure it out on this machine. The lathe looks like it's circa 1938. I would appreciate any help. Also do you know if some of the parts from another lathes are interchangeable - like the compaund, four jaws chuck, gears, etc.
