A rule of thumb for setting the correct height for a workpiece that is up to 1 inch in diameter is to have one half of the workpiece diameter above the centerline of the grinding and regulating wheels. So, for a 1 inch diameter workpiece, the height should be a half inch above the wheel's centerline.

Starting to work out a plan to make the old bench grinder into a belt sander. First hurdle - the motor shaft size. Currently it is 0.98" diameter (with no keyway), and all the belt grinder pulleys have 7/8" a bore. I want to bring the shaft down to 7/8" so any pulley will work rather than try to concentrically drill out a hub - that just won't happen.
