Could someone who is experienced please tell me how to make a simple one-off ID lap? This is a through-hole 50mm (2") diameter 160mm (6") long. The part is a small soft steel (O2/1.2842/90MnCrV8) cylinder.
Details:
I'm making a cylindrical split bushing to hold a grinding spindle. I've turned the ID on a lathe to 50.00-50.01mm and roughed the OD. Next step is to finish grind the OD to 60mm (2.5"). Before I slot the cylinder, I want to make the ID more uniform and improve the finish. The ID should be 50mm-0+0.02mm (1.9685"-0+0.0008") so I should not lap away more than 10 microns (0.0004") from the ID.
Thanks,
Bruce
