Hey guys, thought I'd share an idea I saw recently. The grinding wheel changes the angle as it wears down and the sliding arm (VariGrind) can be different one grinder to another.
Simple answer was to do the initial grind and then take a piece of thin plywood or whatever, cut it roughly into a crescent shape, put one end into the sliding arm stop, place the other end alongside the grinding wheel, and then trace the outline of the wheel. Cutout that shape. Then whenever duplicating the grind put the one end into the arm and then slide it to match the pattern to the wheel.
