I'm experimenting with making joints for cabinet face frames that are made
up of a plain 1 1/2" wide piece with small beads (approx 5/16" wide) on the
sides(. The joint needs to be mitered to the bottom of the bead and then a
simple butt joint. The end of the rail is straightforward, miter both sides
then make a straight 90 degree cut for the end. It's the groove with
mitered ends that is difficult.

Thanks in advance,

Peter
