It's a nice big surface… 65 x 24.. could have been made bigger, but thats what I had room for and thought was big enough. The tables are about $10 each. I drill holes in the feet and matching ones in the tops and use a peg of dowel and wood glue to make them permanently two high. Then I use zip ties around the middle legs to cinch them together. I stuck small pieces of that rubbery shelf liner between them as a buffer so they aren't squeaking against each other and such. And I use a big piece of that stuff on the top to make the plywood grip onto the top… and voila!
