Hello. I am wondering how a person might polish a surface on precision ground shaft. I have done the best I can using "eagle one, mag wheel polish", but am not quite satified with the end results. Was wondering if there are any suggestions as to how I could polish it to a mirror finish. Or...
I am in the process of machining bushings for heavy machinery. If the final dimensions of the bushing are: OD 3.55", ID 2.5" and 1.9" long, how much of a dimension change can I expect after hardening. The material being used is alloy steel, 8620. Thanks
