I bought a Westward 20" 1ken7 floor model drill press that is in almost new condition. However, when I got it home and got it assembled, I noticed a little sticking problem in the spindle travel. When I'm retracting the spindle slowly using the handle, the spindle sticks about 1.5" from the end and it'll hold at that position. It only takes a slight nudge to get pass this sticking. If I draw out the spindle all the way out and just let go of the handle, the spindle will retract all the way in on its own. I don't know if I have a bent spindle or if there is a simple adjustment to make to solve this problem. The previous owner lost the owners manual and I'm planning to call Grainger tomorrow to see how I can get one. Anyone have any idea what kind of a problem I have with my new drill press?
