Good idea, but how do I go about making the little ledge? My Freud
guide bushings go into a hole that is stepped, so that the face of the
bushing rides flush with the base.

The step diameters on my bushing set happenen to match the dia's. of my
router bit set. Need to set the plunge depth carefully or you will ruin
the whole job. It's just a matter of being careful.
