Just to close the loop....

Made some test muntin and mullions today, for divided light. Using the same bits (Whiteside 6003), the only difference was to switch one cutter from one bit to the other, switch the bearing, and put the buts back together.

Worked like a charm, first time. Used the parallel fence technique for safety. Used the Infinity copying sled for the cop cuts.

To my pleasant surprise, the joints were perfect, first time.

Now that I am feeling more comfortable with the techniques, tonight or tomorrow, I will start making the door for the cabinet.
