make a stick of wood that is nice and straight, a tight fit in your
slot and maybe 3 feet long. install the outfeed table where it's going
to go and slip the stick you made into one of the slots so it extends
out over the outfeed table. take a couple of scraps of plywood or such
and clamp them to the outfeed table so they just touch the stick in
the table slot. lift out the stick and run a router bit with a top
bearing between the clamped ply scraps to the desired depth. repeat
for the other slot.

Great idea. Never would have thought of that myself, this is why I
love this board (and the spam is why I hate it).
