I’m building a coffee table for my daughter in California, and want to send it to her finished but unassembled. My question is around the best way for her to assemble the legs/aprons without clamps.

The construction is mortise & tenon.

Option 1 – glue it and use ropes as clamps
Option 2 – countersink holes for screws going through the leg into the tenon. This seems like the best option, but I’m wondering how to get her plugs the right size and finish.
Option 3 – Plugs that stick out of the legs (square tops)

Any suggestions?

Thanks Dave. Yes – built it before I thought too much about the knock down. I think I’m just going to buy her some glue and inexpensive strap clamps. I thought about plugs but think they would eventually fall out – stainless screws and shaker don’t mix well

It would have been cheaper to go out there and buy her one. 10 ft lumber does NOT fit in an SUV, and windshields do crack…

Two words: pocket holes. You could dry assemble the table with pocket hole screws. This would insure everything fit correctly and establish the holes. Mark all the pieces so she will assemble it the same way you did. Then, when she puts it together, she could use wood glue for the final assembly. Have her put blue painters tape at the joints to protect the finish. Be sure to send her the same screws you used. I would use pocket holes for the apron to leg joint and also a 45 degree brace across the legs apron to apron. Should hold just fine.
Just my two cents.

Instead of strap clamps you can use rope with pads on the corners and a stick twisting the rope and a wire to hold the stick to so it can hold the twist in place,

This would do the job well. It is from Rockler. It is a table apron bracket.

Here is the link. Open the technical info PDF

This will work with mortise and tenon construction.

I like DaveR’s sliding dovetail suggestion the best. Minimal clamping would be required for a good glue up, and very easy to assemble on her end. 2 Big boards go parallel 2 little boards go parallel (assuming rectangular design, even easier with square.)

You could use the old style of offset pinning the tennons. It wouldn’t even need glue as the offset pins draw it up tight. If it was glues, they would replace the clamps. The pins could be driven in from the side that shows and not worry about he excess on the inside as it would only have to be about 1/2 inch with a bit of taper to start it.
