I have one of these clamp-on affairs for dressing tool post grinder wheels. You clamp the C on the stock held in the chuck. A diamond point tool is secured into one of the clamp holes & you dress the grinding wheel by skimming across the point. At least I really hope that's how its intended to function.
But I find it kind of awkward. For sure I can set it up this way initially & dress. But if I want to re-dress the wheel on the fly with part already in the chuck, it usually not as convenient. The part itself may well have low stick out, particularly grinding ID bores & the point rarely ends up in the right or orientation. The clamp does not really secure properly to a chuck jaw & a collet chuck is even worse.
I was wondering if I made something where the grinding point was secured to a vertical post & based with a magnetic stand attached to lathe bed - would that be rigid enough? The point has to be on lathe center of course, so on my 14" swing lathe the post itself might be say 4" tall. Any ideas or commercial solutions welcome.
