I recently bought a Boyar Schultz 6x12 Surface Grinder. I purchased a new Diamond grinding wheel 7"x 1.25" x 1/8" Type 1A1. While grinding a 2" diameter face I noticed that one location of the grind is always lower than the rest of the surface. This appears on the back edge on the last pass. I rotated my Vblock and piece 90* and had the same problem. I assume this is due to the fact that the wheel is not square and the wheel could be at a slight angle on the edge and not make contact.
Where can I find a economical truing/shaping brake to square up my wheel?
