I have a 7" 'grinder I put a sanding pad on. I used it for several years and now I want to change it over to a new grinder I just got. The issue is I can't get it to break free from the arbor. It is a very good backer with a heavy alluminum backing frame/wheel with integral cooling ports and a rigged face. I realy hate to chuck this out with the grinder when it is in so good of shape and it cost a small fortune to replace it. Any sugestions on how to get this thing off the spindle?
