Thread: Benchtop Grinder for polishing

Tweet

Most buffing is done at 3600RPM, while some, not all, grinders run at 1800. The nice thing with dedicated buffers is the extended shafts for working material around. A variable speed motor would be nice or if you have the space, maybe build a dual purpose belt drive version with a multi groove arbor, then you would have work around space plus the ability to change speeds, Baldor is the big name in buffing motors. Then there is the Eastwood/Harbor Fright "internationally built".

You may be right about the speed difference and the extended shafts. Our buffing wheels do sit way out as opposed to the grinder wheels that are closer in. We got our buffer at Sears and it has been actually pretty good.
