This is a 27 minute video showing the results of using different wheels and grits and the surface finish they leave. We used 46 ruby, 46.2 white aluminum oxide 60 ruby ceramic mixed and a 120 ruby wheel. some are open structure others are closed. The 46.2 white aluminum oxide and 60 ruby ceramic mixed gave the best finish.

Hi Steve,

Great video, very educational. I recently acquired a vintage manually operated surface grinder, and for someone like me who is just an amateur home shop machinist, I find this is valuable information. Thanks !

Here is a photo of the Alfred Herbert machine I have, and now realize what selection of wheels will be necessary for future use.
