The first bench I built used a solid core door with 2" galavnized pipe for legs mounted with threaded flanges. It worked well enough but wasn't as sturdy as I would've liked. I had this idea in my head that an "L" shape bench with presses mounted in the center should be rock solid and a better way to go. Years later and after a couple of moves, I had the opportunity to build a new bench. The top is 2 sheets of 3/4" plywood (laminated for a 1-1/2" solid top). I finished it with a poured epoxy bar top finish. It is set on Oak cabinet bases with drawers at each corner. It's a heavy SOB but easily taken down to move if need be. It is absolutely rock solid no matter how I abuse it. The "wings" on each side allow for a gun vise for scope mounting, cleaning, etc. It doesn't have a lot of storage built in, but I have free standing shelves around the perimeter of the room for components so that isn't an issue.
