I am building a 2' x 2' bar table, which will be either supported by a single metal base (like this) or by wooden legs at the corners.
For the table-top, I'm planning on using Poplar from Lowe's in sections of 0.75"x1.5"x2' glued together. The edges will use a lap joint with a dowel through both pieces. It'll look like this (crude drawing warning):
My question is: in either configuration - a center support column or corner legs - would any other structural support be needed for the table top (or is wood-glue enough)?
