I have a T8 with an SG-250 waterstone. I have been using it for a while and just recently went to true the wheel. I noticed as I moved the carbide cutter from the inboard side to the outboard side that the cutting sound changed significantly. I have a flat stone, but now when I grind a chisel, the grinding sound is very different on each side. On the outboard edge, it sounds much coarser. I have tried the grading stone with no luck. Any ideas on what is going on?
The cutter is likely skipping over the smooth side as I'd expect one side of the cutter is slightly more worn and not digging in. I had this happen in the past. The grading stone is not aggressive enough to remove material fast enough to get rid of the deep/coarse surface side but if you used it long enough it would even things out likely.
