I just wanted to double check myself on my maximum raised panel sizes for kitchen cabinet doors. With a router bit and a 3/8" groove I always limit my raised panel sizes to 18" because of wood movement of the RP. Now that I'm moving to a shaper with a deeper groove, 7/16" or 1/2", I figured my max panel width should be around 22". This is all assuming the use of KD lumber. I know AD lumber tends to move more.
So what do you consider the "Rule of Tumb" for max RP widths?
Thanks,
John
