I’m interested in building some slab table style furniture. I have a source for 2-2½” dry lumber. While I don’t have to worry about vertical forces, the table may be subject to some “racking” forces. Unequal wood movement should not be much of a consideration since legs & top will be from the same stock and not in a cross grain situation.
Is a series of 1½” tenons sufficient for the joints? Or what should I consider?
Replies
A tightly fitted set of mortise and tenons, in a hardwood, might be adequate to prevent racking for a low coffee table, but a single, or double, stretcher would add considerable strength to any size table and would be a necessity, in my opinion, for a dining table.
The stretcher could be placed against the underside of the top, and would hardly be noticed, or it could be closer to the floor and used as a design element.
The stretcher will have to be firmly locked into uprights to be functional. As a rough guide, a single 8" wide or a pair of 6" wide stretchers would seem about right for a full size table.
Other treatments are possible but something should be incorporated into the design to help the legs resist racking forces.

I used M&T joints for this table and it is very stable. I was just at the clients home recently to take measurements for another project, while there I took a look at the table, it's doing very well. The client said she had caught her grandchildren sitting on it a couple times, the M&T joints did just fine.

Sorry for the delay in reply. Thank you for the advise, and those great pictures! I love them, a great inspiration for my project!
Two follow up issues. Are you using Wenge for the bow-ties? Also, how do you treat the edges, I'm thinking of brass wire brushing to remove any loose fiber and then a green pad to smooth but not remove too much material. What do you recommend?
Thanks again.
Yes, the bow-ties are Wenge. To do the live edges I first used a drawknife to remove bark and punky sap wood. Next step was a brass wire brush. From that point it was hand sanding starting with 180 grit then 220,300, final sanding was done with 400. I used a foam backing pad for sanding. Following sanding I burnished the live edge with Liberon steel wool 0000, then a flannel cloth. It's a little tedious but well worth the effort. Looking back I think ending the process with 0000 steel wool is just fine.

Thanks LJ
I have a few more similar projects I am working on now. One has bookmatched slabs. I should have these completed & photographed late fall early winter, I'll post pics as they are completed. This time I will use better lighting & a back drop.

Timberwerks, just saw a picture of your cherry slab table. Wow, very impressive. Amazing good work.

I'm wondering if sliding dovetails would work well in this situation? Looks like you plan to have the legs and top be the same width. Could look pretty cool. I wouldn't consider it unless you did the stretchers though.
