Prof,
I knew that a velocity increase was in order. The first thing I did, before connecting the machinery was to check the specs on the wheels. They read "Max 4200 r.p.m.". I took that to be fine at 118% of idle speed.
I am assuming that equipment can be run to the rating displayed and that additional safety factors are built in above that by the manufacturer. What does OSHA say regarding maximum speeds versus posted ratings - should additional safety factors be built in?
