I’d probably use dowels from the top of the legs going into the bottom of the top

Nesting tables only need to be open on the front. Maybe consider an apron and even a stretcher across the back.
Or, perhaps a 6” to 8” tall vertical slatted apron patterned after the sides. With each subsequent nested table, reduce height of the back apron so all three have parallel bottom-of-the-aprons on the same plane.

Just another suggestion/opinion is your pattern’s top doesn’t appear to be in scale to heft of the legs. Just my 2 cents.

Looks like a fun project!

Maybe desktop or figure eights. Easy to use, should allow for movement and be sturdy enough for this application.

Sadly, I tried a plan with a back set of spindles and stretchers and it was nixed. Remember too, that I have to allow for the table top expansion….

I would use two dowels to connect the apron to the top. Place these towards the center of the apron. If they are placed within 6-8” of center, expansion will be negligable. For added strength use figure 8 fasteners to connect the legs to the top.
I don’t think wooden buttons would offer enough strength in this application.

Good luck

Bore and counter bore holes up through the aprons just outside the spindles. Drive lag bolts with machine threads on the other end into the bottem of the top lined up with the holes in the aprons. Attach the legs with nuts and washers down in the counter bore. Dont make the holes too tight so that you can have some movement. You could also drive thread nuts into the table top and use machine boles rarher than lag bolts.

I agree that figure eights should be adequate for these tables.

JMO, aesthetically, I prefer to see an odd number of spindles/slats on the sides. FWIW

WARNING – PEDANTRY AHEAD

Honestly? Tell the customer it won’t work. There may be a factory-made set for sale somewhere, but it doesn’t get a free pass from the laws of physics any more than yours would, and it won’t be very long before it falls apart.

What you’ve got there is structurally unstable, IN THEORY. The only thing that makes it stable (and marginally at that) in the real world is the width of the leg perpendicular to the leg/spindle assembly. The ends of the legs bear on the underside of the top out at their edges when resisting racking. One way to improve this strength, therefore, is to make the legs as big as practicable in that dimension.

The real solution is to find a more reliable way to transmit bending force through the legs into the top directly, since you don’t have aprons to take these forces. I just had this thought; take it for what it’s worth. Call it, I don’t know, “T tenons”. Cut 2 mortises into the end of each leg, perpendicular to the leg/spindle assembly. Cut mating mortises into the top, but instead of making them the same length, make them long – well beyond the faces of the legs (you’ll be able to see them). Make loose tenons out of plywood (for its strength in all directions) shaped like wide, stubby Ts. This ought to give you better “grip” between table and legs. Don’t use solid wood; whichever way you orient the grain, it will have a weak direction. Making the top thicker will help, too, since you can go deeper with the mortise. Here’s a sketch.

If you veneered the tops over a man made board, you could just glue/screw the leg assembly on as there’s no movement to worry about.

or

leave a gap at the back end of the mortice for the back edge to contract onto.

Through wedged tenons are your only hope for a wood joint. The commercial version is probably attached with draw bolts. And I would make the top a little thicker because it’s going to be resisting racking force against the legs.

Oluf, I’m thinking your solution might be the most appropriate. The critical thing is to attach that table top to those legs, or should I say skirting. A slightly slotted hole through the skirt, counterbored, using a very thick wood screw. My table top is 1”, and I’m hoping that will be enough “meat” for the screw to grab onto. I think I will also glue the skirt to the top, in the middle, and then put two, perhaps four, slotted screw assemblies on either side of that glue joint. Other than that, not sure what else to do! The tables are just for snacks, and occasional, use, not like people are going to be laying on them…..

Glue and screws will never hold without an apron or trestle.
