I have a Delta DP350 variable speed bench top drill press. The other day I heard a loud bang/crunch when drilling. Looked inside and found the top half of the back pulley had literally disintegrated. Part discontinued/obsolete on ereplacement parts, but found an alternate source here: http://stores.renovoparts.com/-strse...LEY/Detail.bok
Replaced the pulley, press seemed to work OK. After turning it off/on ~ 4-5 times the switch went bad. Seems to be a common problem, found a replacement switch here that fit perfectly and needed no rewiring: http://www.mcmaster.com/#7194k36/=o6w8hx
Now the press works except sometimes it will not go into the lower speeds. It gets to the second mark (~1000 RPM?) and that seems to be its lower limit. If it passes this (sometimes it works fine) it will go all the way to the lowest range and vary speed smoothly until it passes the second mark on the dial, at which point it will no longer go down to the lowest range. Any ideas? I don't use this much and don't know if it ever worked properly at lower speeds, but now that it broke it's really bugging me.
