I have the Delta 36-650, and the freud 8" dado set. This past summer, I
made some tongue and groove floorboards for my porch (7'x25') with this
combination. Granted, this was only 1/4" tongues and grooves, but it did
them just fine. I have some upcoming projects that will use 3/4" dado
blade, but note anywhere as "intense" as the floorboards.
