Been makin’ many large and small doors for years.. I hardly ever use ‘a stub tenon’
For the life of me I cannot see why that little hunk of wood would make a difference.. Convince me!
In china I saw some doors about 20 foot high by 8 foot wide.. About 3/4 inches thick. Double tenons at the corners.. (I just looked at the bottom of the doors).. Had Bronze or something panels! Geeee..
I asked.. The lady said the ‘NEW’ building was about 400 years old and the doors were salvaged fron some place that had a earth quake!
No ‘stub tenons’
EDIT:: DANG About 3 or 4 inches thick! Not 3/4!

I'm trying to figure out what you're saying. Are you talking about haunched tenons or stub tenons?
You got it Iw-I think Will has forgotten what a stub tenon is! What with oggling the Chinese ladies and all;)

I think Will has forgotten what a stub tenon is!Geeee ya folks rough on this old man! The doors were just double tenons.. No stub that I could see....But then again they kept askin' me why I was laying on the floor??I said 'Just lookin' I'm sure they did NOT understand...
Dangit Will, no amount of laying down on the floor is going to allow you to actually see a Stub tennon!
On those doors you could've verified the existence of a Haunch by either simulating a limbo dancer or by resting your chin on the door top rail.Capice?
"stub tennons" OH! Ya mean the short ones????
I'm old so forgive me! Just double through tenons best I could see..BUT I'd bet that was REALLY OLD GROWTH TIMBERS!
Even a "stub tennon" makes a big difference. A butt joint consists of glueing only endgrain on one piece to long grain on the other. End grain makes very poor glue joints. If you add even a small 3/8 tennon/ mortice to that joint you will double the surface area of the glued joint (on 1" thick stock) and more importaintly you will have long grain to face grain surfaces glued togather, which hold togather much better.
However "stub tennons" are much less strong than regularly porportioned tennons. The only reason you see then at all is that there are shaper bit sets that make this type of joinery very fast and accurate. If you are making the M&T joints the way most small shops do it will take no longer to make the tennons longer and the mortices deeper.

End grain makes very poor glue joints.I sort of agree.. I have made MANY BIG doors.. Just through tenons and doubles if the door is really thick...I have never had a 'call-back' on a tenon that gave out.. Maybe a split panel!
