I am the new proud owner of a 1948 square dial 10EE. The machine was in use in a small rural machine shop, and by all appearances pretty well cared for. I ordered a 5c collet nose for it and was checking to see if Chinese chuck was of at least decent quality. This was the first time I had even put a DI on the machine. Found about .0025 runout on a ground piece of .5" drill rod. Long story short, I have determined that taper for chuck mount is not pulling in tight before chuck seats against spindle face. The spindle taper checks true with my .0005 indicator, like wise the face. used hi spot blue on spindle and printed new collet nose as well as 3 jaw that came with. Both showed a solid contact on face and barely any contact on taper. I suspect I need to remove a little bit off of the spindle face, but want to make sure, and need some advice as to method.
