Although this isn't my first time making raised panel doors with cope & stick joinery, I am still learning it. I recently purchased the Amana 54116 panel cutter for its small profile. I am struggling to figure out how the small tongue it creates is supposed to fit into the 3/8" deep groove in the rails & stiles. If I use that bit deep enough to create the 1/4" tongue, then it fits in very shallow, This also makes the panel face stand proud of the R & S face. I prefer that the panel face is flush with the R & S. however it does not have too. That is just my personal preference. I thought about back cutting the panel with a straight bit, but this still seems to not get me anywhere besides flushing the panel face to the R & S. What part of this am I just not understanding?
