Some time ago I posted this question: I have a 7" grinder and want to run CBN wheels which come in 8". Can I convert my grinder to run the wheels? I could not get a definitive answer from anyone including Baldor's engineers. So I ordered two wheels from D-Way, Took off the guards and installed the wheels. Works great. I didn't have to modify anything. No more dust, no more wheel dressing and no more wheel replacement.
