I want to glue up 3 2×4” boards to make some legs and stretchers, Is there a reason this joint won’t work? as opposed to glue up then cut out.

It will work, plus you should be able to get a nice fit with clean shoulders. I am assuming your drawing is not scale and the tenon will fit the mortise…of course.

Problem would be in keeping the parts lined up during the glue up. Maybe add a tenon sized chunk, wrapped in wax paper or plastic tape. When the glue is dried, you can then just knock the plug out.

That’s the way I made the legs and stretchers for my bench, worked for me.

That’ll work…...and +1 for bandit’s suggestion…

Ya I was planning on doing it bandit’s way.So how come you never see anyone doing it that way? seems everyone glues then cuts and chisels.

Can control how tight the joint is.

I’ve seen a number of bench builds using this approach. Doesn’t Paul Sellers do something like this on one of his builds?

Built my bench out of laminations like that.
Mine was all built out of 3/4” plywoood layered to be 4×4 legs, 2 1/4×6 stretchers, tenons are 3/4×6 x 4 long.
The concept was exactly the same though. And i used the wax paper wrap on a dummy tenon during glue-up.
All this worked perfectly. I love my bench. Been using it since 2008.

Daddywoofdawg, there are Youtube videos of building the “Roubo” style double mortise and tennon using the same idea and many examples of the 2×4 layup also.

It will work. Bandit’s idea is good. Even if the tenon is a little small or large you can trim it down or build it up a little like any ill fitting M&T joint.

This joint has been used before. The reason it is not that popular is the glue used to hold the wood together. Ppl prefer to use a single piece and cut out the tenon or mortise.
