I realized I was going to need a new bench for my build to fit the wing assembly and eventual the welding/assembly of the fuselage. Using the basic EAA bench design but made it bigger and wider. Basically built to benches, tied them together with a couple of brackets and put both on a set of rollers so I can easily move them around when needed.

I made my table at the time the full 4 foot with which was nice for building full wing, but I thing I would have been better off overall to build them only 32 inches or so – just wide enought to get both spars on table along with wedge blocks. That should be enough for fuselage too. The size would be dependent on your build and its dimensions. A narrower table would be better for moving around the thing and also for being able to reach from one side to the other without having to walk around.
