What happens when you tighten the grinder's shaft nut? Does the diamond

Whoa. A grinder is a high speed tool working under a heavy load. Get
the part that fits properly and is meant for that application. No
bailing wire and duct tape solutions for this kind of tool. It's a
gruesome accident waiting to happen.
