All of this supposes that your drill press table is at precisely right
angle
to the spindle axis, and that your drill chuck has zero runout, neither of
which is likely true, especially if you're using something you bought at
Home Depot.

Oh, so next I 'spose you'll say it was foolhardy of me to bid on doing work
for NASA with a Shopsmith??
