I am building a small bridge for a dance prop. It consists of three major components; two ramps and a stressed-skin platform.
The front of the bridge will be sculpted foam board.
I was planning on making a non-structural railing out of foam or 1/4" ply, but I just learned that the dance will have the dancers leaning and VAULTING over the railing.
So now I have to figure out how to make a structural railing that can be quicky installed/removed (several minutes).
I bored some 5/8" holes in the stringers (similar to lightening holes) without a whole lot of consideration of how to make this railing. My initial thought was making three of the verticals strong enough to resist the moment of the girls flinging themselves over the railing.
I don't have access or skill to do any welding. One thought was to use 5/8" threaded rod and bolt it to a 2x2 vertical. I'll probably use tensioned diagonal cables to keep the assembly from racking.
Attached is a sketch of what I'm planning. The colored sections are the individual railing assemblies.
