need help with joinery on table

I am making a simplistic coffee table. I want the the top to be out of one piece of wood and have a knot in it that i can knock out. The part that i need help with is the legs i want there to be four legs one by each corner however i don't want to use an apron.

With just a top and four legs, you could just install the legs with a M&T (mortise and tenon). Make the end of the legs fit a mating hole and glue in place.

It can be done with a loose tenon, which can be as simple as a single loose dowel that fits a hole in the top of the leg and the underside of the top. Install with glue.

It will take some very close fitting parts and pretty wide tenon shoulders on your legs but it can be done. Are you planning on through tenons?

The top would need to be kinda thick (for glue surface) and the legs would need to be pretty dang big (cross section) even if the only taper up to it. I can't stress how accurate your tenons and mortises need to be for glue strength though.

You need to provide more information.

What is the top material?

How thick is the top?

How are the legs to be aligned with the edge of the top?

What is the material of the legs.

What are the dimensions of the legs?

A mating hole is a hole that is drilled and sized so a dowel will fit snugly (with glue).

What is the top material?

the top material will likely be black walnut

How thick is the top?

probably around 2 inches

How are the legs to be aligned with the edge of the top?

they would be at a 90 degree angle 1 inch from each edge

What is the material of the legs.

the leg material will likely be black walnut

What are the dimensions of the legs?

16 in tall by 4 in by 4 in
* edit i thought about the legs will i be able to taper them down towards the bottom without affecting the strength of the joint?

With a 4"x4" surface, you could likely just glue and clamp. That's a lot of glue surface. Or do as I suggested, make a mortise in the top, and a tenon on the leg. Or, drill corresponding holes in the top and the leg, and install the legs with dowels. Two would be nice (including the rest of the area of the leg is also glued).

Sounds like very sound design criteria. You can absolutely taper the legs! You really just need wide cheeks on the tenon for support. It should be a really cool table.

c-man you type too fast, lol.

It sounds like he's wanting to do through tenons on the legs, so the dowels are out. I hope he pillows them! Tha'd be cool!

I'd say anywhere from 1.5"x1.5" to 2"x2" should be fine. As for pillowing that means it extends through just a bit and the edges are beveled.
