I have a 74 Craftsman drill press (113.21371) that has considerable runout. I took the chuck off and when I spin the spindle in the quill I can see the chuck end of the spindle wobbling.
I’m pretty sure that the spindle is bent and its not something else causing the runout but I’d like to make sure before I order a new spindle. Any advice?

Hennessy, I don’t know that particular press but if it has a morse taper spindle I’d remove it, clean it up well, and reseat it. Sometimes a little corrosion or other residue on/in the taper will cause runout. Just don’t use a lubricant to clean it or, if you do, clean it off very well with something like alcohol.

Good luck, Mark.
