Sorry if this has been mentioned elsewhere on this forum. I searched and could not find a similar post.
I had trouble tracing down a source of grindstone "hop" (radial excentricity) despite truing with TT-50, and also installing new nylon bushings and shaft.
Finally tracked it down to enlarged arbor hole in grindstone. Solution is to just line up the stone and the shaft in the same direction, every time you swap stones.
Quickie YouTube attempt to explain problem and solution. The improvement is noticeable (hard to get on video, but it is a real improvement).

Has this problem been noticed before? I did not find any mention of it in the User's Manual.
Thanks,
