The diamond wheels are MD120's 7" dia. 1/2" wide, permanently mounted on the hubs & sent out to the factory for bottom truing & balancing. I need to get a good surface ground finish, but the wheels are not quite true- thus leaving a slightly ripple finish. I know we should have a brake type wheel dresser, but the boss won't budge for it due to its cost for the very little carbide grinding we do. We have the white dressing stick for de-glazing it by hand, but does not true it. Years ago I ran across a dressing stick 3/8 dia. made out of some type of sintered material mounted ridgid when dressing, that actually would dress a diamond wheel like a single point diamond does on a regular grinding wheels. That dressing stick wore quite fast but removed some diamond from the wheel, allowing the corners of the wheel to be squared & the bottom true. I can't seem to find it any more. Has anyone used one of these, what is it & who has them. If I remember correctly they were around $20-30?
Thanks
