Be sure to use only precision ground shafting. Most ordinary round stock will have to be turned end to end to fit thru bearings. McMaster 9063K21 is precision ground stock. It fits right thru bearings smoothly. I have a file for a 36" axle, half the keyway is on one side, half on the opposite side. Your machinist can position the keyslots as you prefer. I've been running them for several years with no problems. If you want the PDF, PM me with your email address. Ted
