Put a rod or drill in the chuck and line it up visually with a right angle  
set at the table. That's very precise if you look against a light. You  
need to do it from at least two angles of course.

For holding the spindle, if you have no good straight section use v-clamps  
or something on two points, one near the business end and one somewhere  
above. That ought to be dead stable then.

I haven't found a quiet drill yet, the brushes seem to make much of it.  
Better quality grinders make less noise, but still not as little as a  
brushless motor.
