I bought a Delta 17-965 16.5" drill press, put it together, and am experiencing unacceptable vibration (the head shakes, the table shakes, everything shakes) that didn't exist on the cheap Craftsman some electrical engineers put in lab space I shared.
Belt tension makes some change but does not appreciably reduce it. With the belts off there's a tiny amount from the motor. The belts are oval shaped as shipped but don't seem to have a real set. Regardless of belt tension the idler pulley bounces arround a lot. A straight edge across the pulleys shows the spindle and motor pulleys are level but the idler pully is significantly (1/4"?) below them. I have not yet put a dial indicator on anything to look for runout.
Help!
