Need some help on this one...Recently undertook a bit of a restoration on a Delta DP220 drill press. Now that everything in cleaned, repainted, & put back together I checked the runout using a 1/2"in. & 1/4"in. drill bit in the Jacobs 6A33 chuck and it came in at a whopping .032 !! So I'm thinking I either have a bent bent spindle or bad chuck, not sure which at this point. I took a measurement with a DI at the lower bearing drive collar (I believe that's what it's referred to as).....This was as close a reference point as I could could get the DI into to try to measure the spindle. Would this point give me an accurate indication of whether the spindle was bent ?? The DI showed .002 runout there.
