I'm assuming that the two things you want aligned are the bore perpendicular to the large face and a key way in the base. I was wrong in referring to the key way as a t-slot. In the original mail you were referring to making a hole perpendicular to and aligned to the center of the bore. Couldn't see a hole in the drawing and it looked like there was a key way aligning the center of the bore to the center t-slot of the table.
One more setup then; large face down and face cut base, then base down and face cut large face, back to large face down and skim cut on base and cut key way on base. This gets the two faces perpendicular and the center of the key way perpendicular to the large face. >> sweep the two sides of the t-slot to center spindle on slot > When you say "T slot" do you mean the one in the table?
