Welcome to Anal Corner! I mentioned some time ago having bought a new Norton SG series grinding wheel, which caused my likewise new bench grinder to do a bit of a dance after installation. The stock wheels were dead true, with no vibration or discernable movement. Since that time, I purchased the Oneway balancing system, which tamed the vibration quite a bit, but there is still a bit of side to side wobble present. . Having recently mounted a sharpening jig, I have a way of measuring the wobble which comes out to a variation of .018 between innermost and outermost travel of the wheel relative to the side of the jig.
I had resigned myself to live with the residual wobble, but the jig makes it much more noticable. So my question is, should I return this wheel, or am I just totally nuts to worry about such a small amount of travel? I'm obviously still in the process of learning what tolerances apply to woodworking equipnment.
I have a diamond dresser to dress the cutting edge of the wheel, but this is clearly a case of the sides being out of whack, perhaps the center hole is not true to the rest of the wheel. The wheel balancing system provides a very solid aluminum arbor flange with no play in it, so it would seem the problem lies in the wheel itself. I haven't actually used the wheel yet, having been focused on other projects, but now I want to get into some serious sharpening.
Thanks for your help.
