I have read that stub tenons are not recommended for kitchen cabinet doors or heavy use doors & because of the short length of the tenon. Would gluing the panel add strength to this joint? I know that gluing a solid wood panel would interfere with wood movement, but what if I used 1/4″ plywood panel and glued along the entire inside edge to reinforce the joint?
Michael Dresdner: Yes, gluing in a plywood panel would most assuredly add strength to the frame.
