No competition
for strength and durability on a door of that width definately wedged
'traditional' mortice and tenon joints. Coming from the old school i think
of loose tenons as overgrowm dowel joints relying totally on adhesive to
retain strength whereas a well constructed wedged mortitice and tennon joint
will actually hold itself without relying on the adhesive

Building an old growth fir front door. 2 Rails and 2 stiles(42"x80") which
will have a 30"x60" double pane of glass in the middle. I'm going back
and
forth on traditional M&T joints or a floating tenon joint done with my
plunge router (I've done lots of these joints before) I'm concerned about
the strength and particularly whether this joint will support the racking
forces once the door is hung. I'm thinking 1/2" think tenons by 5" wide
and
2 1/2" deep mortices. Any suggestions on the sizes needed to keep this
together?
