For the price, those things are remarkably handy; I bought one, removed the 2 wooden strips and the clamping mechanism which left me with a foldable set of legs. I fixed my dovetailing jig directly to it. It's still foldable and compact, and hangs on the wall.
Maybe do the same for a small welding bench - remove the wood & clamps, bolt a sheet of steel in their place; nothing inflammable remaining, just a handy, stable and foldable welding bench. Cheap & portable.
