I picked up a P&W Radius Grinder, either an R6 or R8.. Not sure which. I got it cheap at an auction a while back, and now have some time to give it attention. It didn't come with a vise or tool holder, although I have a 5C collet ficture I can put on the table. My main thought is to use it for accurate grinding of HSS lathe bits, and more specifically, form tools.
That being said, it appears that I'd want a diamond wheel for sharpening brazed carbide, but what type of wheel for sharpening HSS? I'm new to grinding, so it's all very foreign to me. I'm guessing from the look of the wheel guard this grinder is supposed to take around a 4" diameter stone, with a fairly small arbor.. Is there any reason I can't put a stone with a larger arbor hole if I machine a steel arbor spacer to fit? It seems most of the T&C stones have large (1" plus) arbor holes in them.
Thanks for any advice.
