I'd like to see Festool come out with a stationary domino cutter similar to my old Delta stationary biscuit cutter. Clamp the work piece to the work table with a air cramp, push the air valve and presto it cuts the slot.
Do you have to clamp workpieces? Could you hold a 24x30x3/4 piece of ply in place while plunging without clamping? Maybe press straight down with your hand and press the ply toward the fence with your torso?
