How to join these legs

[Fidel Fernandez]

I want to make a side table like this one for my living room, but I have a question about the legs.

I know how to join the legs to the top. It could be using some dowels, tenon, dado, etc. One thing that I cannot figure out is how to join the legs. I don't think is as simple as a butt joint and glue.

It should be a mechanical joint and glue, to put the 3 legs together before they are connected to the top.

Any ideas?

I might try some version of finger joints with small angled shoulders and enough fingers that I could stagger the interlocks among the three legs. It's a tiny incidental table, not a stool, so it doesn't have to hold 200 lbs or anything.

Crap someone's already patented it!

[Fidel Fernandez]

It makes sense.

I didn't know you can patent a wood joint. That means I cannot use it unless I pay royalties...

That patent is > 20 years old so it is now public domain. Don't let it stop you Fidel.

Well the description says it's entirely hand carved. So no joinery needed

Sure is an awful lot of whittling though.

I'd have to look, but I swear this was covered in either Tage Frid's book, or the other joint book I have…. I'll check when I get home…

If i had to do it, I'd cut a 3-way miter and then use slip tenons.

Three way sliding dovetail spline.

Well, if biscuits are good for joining two pieces of wood, then triscuits should work in this application.

(C'mon...somebody​ had to say it!)

Never mind, everything I thought I remembered from my books where three legs joined to a solid center…

Lol...laughed out loud on that one.

You'll need splines, of some sort to get long grain to long grain glue joints.

Three 3/4" plywood triangles to go laterally.
Three 1/4" plywood splines to go vertically.

Notches in the legs to accept the lateral triangles.
Grooves in the leg "faces" to accept the vertical splines.

Have three layout triangles at the ready, for glue up.

I suggest clamping two legs together, first to make it less fraught.
Add the third after the first glue up is dry.

You could also do a modified Maloof joint on this:

Cut dado's in each of the legs that fit around a central, triangular block, and then screw or dowel each leg into that block from the outside. Plug and fill the holes.
