Use any bit that can rout a channel.
We used this dish-carving bit to
create a 3/4"-wide relief necessary

Routing a relief channel

With option #3, rout a 1/4" channel along the bottom of the insert deep enough to give the blade initial clearance, photo right, when you place it in the saw. However, do not rout deeper than half the thickness of the insert. More than half would weaken it and create a potential safety hazard.
