I bought a couple norton 32A 8" 100 grit grinding wheels and they are so unbalanced they shake my table almost across the room. I have a delta varible speed and thats on slow. No way you can turn it up on high speed it shakes so bad.

I ordered one of those oneway balancing systems and realized when I got it it won't work on these wheels. The hole has to be 1" to work with the oneway system. These are 5/8" for my 8" grinder.

Does anyone know how to balance these things so it won't be this bad?
