CAM CENTERS
When I need to polish the main journals on a camshaft, I use a straight shank center, or a large center drill will work. Insert the center deep enough in the chuck so the Cam pin or a stud will rest against a chuck jaw. All Cams have the centers on both ends, so in the rear have a center in the tail stock, take up the slack and go to polishing. The ” Old Machinists ” did this with Drive Dogs on their Crank Grinders and Lathes.
