I'm making some raised panel doors this weekend. The style I am making is
simple groove in rail and stile -- no ogee or anything. In the past I have
made the frame of the raised panel using mortise and tennon construction
using my Leigh FMT and then groove the interior of the frame with a centered
1/4" bit. I was looking at some raised panel bit sets to see the how they
attached the rail to the stile and it would appear that there is no "large"
tennon or tennon like structure -- although the joint also has a lot of glue
area and good part of it is long to long grain. If I carry this idea to my
design I would mill a 1/4" x 1/4" groove down the stile and then form a 1/4"
stub tennon on the rail. Obviously a 1" deep full tennon would be a
stronger joint -- just wondering if anyone has any experience making door
with the 1/4" tennon and had luck with them holding up over time.

BTW the application is a media cabinet -- CD's and DVDs -- nothing too
strenuous....

TIA
