Upgrading to a 20" disc sander from a PM 12"disc/6" belt combo. Generally, most new and older 20" sanders run at apx 1740 rpm. I have never really thought about that but that speed seems fast for WW applications? I know Steve Rowe aka "Extreme Woodworker" has a good YouTube vid on his 20" Jet with a VFD add-on to slow his down. And while I agree with him that the speed is too fast, I can't stop thinking why are they all so fast? And... are they really too fast. Looking at the specs of my 12"disc combo, it turns at 2300 rpm and I never once thought about the speed. For years, pattern makers have been fabricating patterns with these big sanders at 1700+ speeds so it must be fine????
Anyone with these larger disc sander opinions???
Dave Kumm???
