The problem: Creating, for example, angled dados and rabbets or other
decorative grooves, with the router.

Yes, I know that angled dados and rabbets can be done with table and radial
arm saws, but I'm looking for something much more general. Perhaps an edge
beading that rises from the bottom to the top of an edge of a board.

Things I've already tried:

1. Attaching an appropriate shim to the bottom of the piece and then run it
across the router table

2. Attaching a shim to the sub-base plate of the router before routing a
piece.


Any other techniques, jigs, etc?

TIA
