How can I domino this 3-way joint?

[smorgasbord]

Stock is about 21mm thick (seen on edge above), and about 60mm wide. Obviously, I could join Pieces B and C to Piece A, but then Pieces B and C are not attached to each other, see dominos in red:



I was thinking about doing that last piece with parallel to each other, not perpendicular to the faces dominos:


I'd do the red domino first to join A to B, then bring C in with two parallel dominos. Seems iffy.

Any other ideas?

This is for a table base:


And table:


I'm not yet happy with the proportions. I'm trying to do a variation on a Mission table, except with hexagonal legs and hexagonal spindles, and a 3-part base instead of the standard 4-part. The top is 900mm in diameter and is 840mm above the floor (It's for an grand entry table under a big chandelier). So, it's a bit higher than normal dinner tables/desks.

I'd go with the second option myself, this will also give you a very strong joint with the increased glued surface area.

Ugh, boss just nixed the 3-legged design. Back to the drawing board (app).

Three-legged tables never wobble.
You may not need it, because of the override, but a connection like that first pic is possible. It depends on size, but a three-piece joint just needs to all slide together at once. Clamping is the biggest challenge. Band clamps or some kind of fixturing can do it.

Current favorite of the boss:

Standard 4 legs, kept the hexagons because they're the bestagons.

Make sure you get a commitment from the customer, so she doesn't change her mind once work commences! ;-)

Yeah, I think the design is somewhat boring. After all, it was done to death 100 years ago. But, our house is a combination of antiques, modern lighting, some updated Craftsman stuff I've built, and even some Nakashima pieces, so it'll fit in. I'll make sure to choose some nice boards for the top.

Maybe we could commission something from Mira Nakashima or Thos Moser, but she wants something that's 84cm tall and 90cm in diameter (about - this was done with rulers and such on existing tables), so it would have to be custom and we want the quality to be high, so.

At least with the 3-way base I'd have a challenge to keep my interest up. I think I'll make my challenge getting this done in a timely manner, which is not my normal MO.

So make the legs the best bestigons they can be. Build them from six staves each so you always have quartersawn grain facing out.

How sensational would that look!
