I've made quite a few raised panels, but all with a shaper, so as to get the flat tenon around the edge. I would like to cut the profile with a plane, but have not had luck at finding a pair of left/right panel raising planes to do the job. Closest I have is a pair of 48mm fenced rebate planes.
But this leaves a tapered edge. Someone told me this is OK. But my logic leads me to think that that even-width tenon is needed around the edge to allow for wood movement. I can't see how, if it is tapered it would not become loose when it shrinks.
Thoughts from panel makers?
