So I bought a set of 2" long sanding drums for use with a drill of drill press and I want to use them as a splindle sander in my drill press. My question is what speed do you guys normally run them at? I have the 8in benchtop drill press from HF and I have the belt set at the second to highest point on the pulleys. It gets some serious vibration it I push the piece into it to hard. Is it just a finesse thing where I have to do a lot of light passes or just lower/raise the rpms? Thanks in advance.
