If you make a hexagonal table, you can use hexagonal legs. You will be able to make mortises in the legs that are square to a face and then skipping one face of the leg, make another mortise. You aprons will all be square cut tenons.

You can do it at th tablesaw by setting your saw at 30°.
Let’s say you want 1” faces on your hexagon. Square root of 3 X 1 = 1.732…..... (square root of 3 being a constant) so this will be your stock thickness. Your stock width will be 2 or twice your face width. Now make a mark at 1/2 of 1.732 along that side. With your piece lying on the wider side, set your fence so that a 30° cut goes right thru that mark. Turn it around and cut again, flip it over and cut two more times. I had to do a bunch of research to figure this out.

This is very helpful. Thank you for the clear explanation.

I did some math wrong. Standby. Ok, it’s fixed.
