Hi Greg, Thanks for the reply.
We don’t actually notch the rails or stiles. We mill a separate piece of stock 1/4 x 3/4 with the bead on one end then glue and pin nail to the inside perimeter of the frame openings. The extra material isn’t so much of an issue as the door and drawer fronts and boxes change size due to the openings losing the 1/2″ in width and height.
Thanks again,
