SawStop dado insert
SawStop inserts are expensive and may not be readily available. I needed to make some small drawers with 1/4" dados. My dado insert had already been cut to 3/4" wide so my cuts would have been unsupported. I needed a new insert.
This is my prototype for a shop-made insert. 3 relief pockets to clear various protrusions, 4 leveling screws, a finger hole and a small magnet. Now I can cut a batch and have a zero clearance insert whenever needed.
