The classic way I've heard is to take a block of wood, bolt it or clamp it
to the DP table, then use a forstner, spade it, or whatever you have
available to drill a hole into the block the same diameter as the dowel.
Now, WITHOUT CHANGING ANY DP ADJUSTMENTS, replace the forstner (or
whatever) with the bit you will use to drill the dowel, put the dowel in
the hole in the block, & drill.

how do you know the hole is centered if you don't know if the dowel is
straight and the bottom of the dowel is square to the side?
