Hi All -
I'm building a table. The top is 1 3/8" African mahogany, 144" x 36". Best I can tell, its about 54 board feet, and about 150 lbs. As it is today, I have two legs which are roughly 24" long by about 3" wide where they meet the table/5-6" wide at the floor, at 3 and 9 feet (so there is a 6' span which is unsupported in the middle of the table). I guess its what you'd call a trestle base; I connected to the two legs with a beam roughly 2" x 6", through-mortised and using a wedge to hold it all together and allow relatively easy disassembly.
My question is about the strength of that top and its ability to support itself over the 6' span, or if it needs to be supported in the middle. The top was originally two pieces, jointed and glued with Titebond 2 and Dominos. Does anyone have any thoughts about this, or is there any formulaic way to determine what is or is not necessary?
