Personally, I would use a dado set and have "fingers" the width of the dado
setting.

That said, chipout should not be a concern, as that han be handled with
backer board.

I made a Lynn jig for cutting box joints on the table saw. Can anyone out
there give me a recommmendation for what saw blade to use in this
application? Seems like a rip blade, while flat ground, would cause too
much chip-out. What other blade would give me a flat-bottomed kerf?

TIA
