I have been sharpening my tools on an old (3600 +/- rpm) bench grinder with good AO wheels and never burning a tool. A few days ago I got a slow speed (1725 rpm) grinder at Woodcraft. I mounted it up to my Wolverine, dressed the wheel and burnt my gouge on the first try. The 120 grit wheel ate into the steel like butter, I put no pressure on the tool.
It took me two hours to get the grinder and jig perfect but I'm ready to return to my old grinder and use the new one for sharpening shovels and hoes. Is there a trick to using a low speed grinder or did I just make a bad decision?
