That likely will need a better, finer grained encoder than my 50 slotter Andy, although I have considered trying to duplicate someone I saw on you- tube a year or so doing the hex flats for a wrench with a cutting tool mounted that way. But it was rather obviously at the end of the spindles available slow speed torque doing it with many near total stops of the spindle. The PID was obviously working serious overtime. For grinding there wouldn't of course be anywhere near the torque requirement that cutting needs. With my setup I can turn fairly steady at 10 rpm no load on my mini-lathe. An interesting project for sure, David. you-tube movies would be great, not only for that, but for the first time its fired up too, hint hint. ;-) I've seen a couple V12's running, but not a radial. That would be quite a statement about the artist IMO. Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
