Check that the shaft isn't bent.This could save you the time spent
balancing the blades,only to find that the shafy has been bent and it still
"wobbles"

My Black&Decker electric mower was loan to friend. He ran the
mower over several boulders several times, chipping a couple
pearl size sections off the blade. Possibly, this is causing the mover
to vibrate to the point of causing a shoulder sore.

I remove the blade, then clamp it to a vise grip. I have an angle
grinder that I will use to fix the balancing problem. The problem is,
I've never done this before. What is a practical way to balance a
mower blade?

Thanks
