I just got a Hartford vertical mill. I took a chance on it from HGR in Ohio, it showed up the other day and for what I paid for it everything looks great. The only issue I have is the spindle bore is not R8, Erickson qc 30, or nmtb 30. It is an 1 1/4 straight bore about 2 inches deep with one set screw in the side. Has anyone seen this or know what it is? There is no hole in the splined shaft for a draw bolt
