You can wrap a panel if the grooves are deeper than the panel width so the panel floats. You can use a single pin or spot of glue in the center,top and bottom. The panel can expand to both sides from the middle. Good rule of thumb is 1/8" deeper on each side per foot of panel width.
oh a cove cut ... ok thanks for clearing that up. It does give a cool effect I think and could be nice for some applications. I will have to check out Matthias' calculator so see what I can learn from that as well. so how would you recommend doing the door frames? Not wrapping them at all or what?
