Table Top Question

[TexasTimbers]

Now that you bring up design, and we are departing KISS,  here's another possibility. This isn't a very good pictutre but if you use your imagination, picture the corners mitered with no end grain at all like this one has and contrasting colored splines.
This is Ash with 15° walnut dovetailed splines having a 1° taper.
The 1° taper is the key to getting them tight. And they are tight tight tight. Tap them in too far and they will split the wood. No need to mix up any goop to cover cracks cause there will not be any.

If ya need to park a truck on that table, keep all grain running the same, miter the ends and put about 3 - 1/2" beadlocks in each joint....keeps the joint from moving and adds a ton of strength...the round edges on the beadlock has more glue surface than square floating tenons

Beadlock Kit

Just another way to do it  ;)
