auto-balancing bench grinder arbors

[C-Bag]

Thanks for this matthemuppet. This is a problem that has plagued me with my 8" grinder. I helped the problem a lot by truing my wheels on the mill first. I'd also seen the Norton wheels are better and more balanced assertion before. After going out and buying a set I'm also in the camp that says thats a pant-load. What I did find is they were all so off center, how could they even be in balance?

The link you provide is very interesting and I'm going to have to read through it again a couple of times. I do wish he wouldn't use washers and instead say arbor as its kind of confusing.

I look forward to your further experience with the self balancing arbor as it seems easier for me than making the balancing blades/washer set up. It's a mystery how you figure out how many and how big of ball bearings you need too.
