Any one else having issues with the Blaze belts in the lower grits wobbling unacceptable amounts. I have never had an issue with other belts wobbling on my grinder or a friends, but it seems about 50 percent of the Blaze 50 grit belts wobble a bunch, today i tried 4 belts, 2 were ok, for Blaze, and 2 had a quarter inch of side to side travel. I like how they grind but do not think i will be buying anymore of them.
