I do have a mini table saw that is about half the size of a bread

Build a jig for that, Darren. A 1/8" piece of lauan ply made into a
crosscut sled, with runners on the bottom to guide it over the mini
saw table top. Glue a tall strip on the far side, perpendicular to the
blade. The first cut puts the slot in the strip (fence) and sled. Now
mount a t-slot into the top of the fence and run a flip stop on it,
perhaps with flippable shims to allow the dado width.


Put 2 blades together?

Or, if he can find a really good glue...
