Customize the inserts to fit your tablesaw
Now that you have the blanks cut to shape, make a finger hole (for removing the insert) by drilling a 3/4" hole through each insert. Keep it at least 1" to the side of where the blade will project through the insert.
On many saws with 10" blades, the blade retracts only 1/4" or so below the table surface, photo right, meaning your unkerfed insert blank won't sit flush with the tabletop. You've got three options here: First, use a smaller diameter blade--like one of the outer blades from your stacked dado set, or a blade from your portable circular saw--to cut a relief slot that your 10" blade will fit into. (Unless the blade you use has the same kerf width as your 10" blade, don't raise it high enough to break through the surface.)
