I made a bench grinder out of one of these. Saw one in HSM years ago,
finally got around to making my own. I don't recall off the top of my
head what the size was, but it was a light press fit into standard
bearings available from MSC. I run mine up to 3000 rpm all the time.
This, btw, allows mounting grinding, buffing, wire wheels, etc on
mandrels which can be changed very quickly via handwheel drawbar, and
don't need to be trued each time for normal offhand grinding.
