54" table top - Bope - 09-14-2015

I am planning on building a 54" diameter octagon table. The legs are going to curve up form the center to the outer edge of the top. The top will be 3/4" baltic birch ply with some fancy veneers. Do I need to run any bracing under the top to keep it from warping or sagging? There will be a 3"-4" hardwood band around the outside and a 2" skirt underneath. I have not built a table before and the base is going to push my woodworking skills so I am a bit nervous and want to get it right.

No expert here, I've only built one table (52" round).

You said you were using a skirt and a hardwood border; that sounds stable enough to me.

A picture would help.
A good joint with the joint landing on a leg piece would be best.

Veneer both sides equally (not pattern)

To keep it from being tippy
I would suggest 70% of the top or 37-38" diameter

To avoid warping, make sure that both the top and bottom are veneered.

I agree.

If it's 3/4 ply, with a skirt, and the legs are flared out as support, it's going to be a pretty sturdy top.

I'm assuming the flared legs are going to be structural, so the only place it can really flex is that last bit of overhang outside the legs/skirt, which is mostly a hardwood border anyway?

In about 1970, my first husband glued two pieces of 3/4" ply to make 1.5", cut a 48" round, and put it on a center support. No skirt, etc. It has never budged.


Re: 54" table top - Bope - 09-15-2015

Yes both sides will be veneered. The picture below is the base I am trying to make. The flared legs will be supporting the outer edge with no support in the middle. I was more worried about the center possibly flexing or sagging.

For the bottom curved pieces I was planning on band sawing. The large curved pieces I was going to use bent lamination using cherry. I am all ears for any suggestion on how to build.

Why veneer?


Re: 54" table top - DonJuvet - 09-15-2015

My best advice....


Start with something easier

Sounds ruder than it is meant.


Re: 54" table top - DogwoodTales - 09-15-2015

Never built one of these before? Maybe take the time to make one out poplar before committing to more expensive materials. Just a suggestion.

As for sagging in the middle, unless you're looking to do long term storage of an anvil in the middle of the table, or use it like a Coyote Ugly dance floor, I doubt you'll have issues with the middle sagging.
