I make a lot of laminated table tops from reclaimed lumber, (mostly pallets). I built a glue-up table using the great 12" X 48" X 28.5" table frame from Rockler. I wanted a 16" X 56" top, so I considered all the options for materials. Ended up using high quality 3/4" plywood, glued up 3 pieces thick. Very happy with the stability of this surface. Thought about formica for the top, but the wood was so perfect, I polyurethaned it over a week to give it time to cure between sandings. Everything I glue is a maximum of 12" wide, (12.5" planer), so I use baking parchment paper, (15" wide), to protect the surface while gluing and finishing. Built a shelf under the top to store wooden cross pieces used as hold-downs for gluing. By the way, not having bought lumber in six or seven years, I was amased at the cost of plywood.
