If I built a box using standard diameter scaffolding tube (48mm) and connected it using kee clamps rather than standard scaffolding connectors, do you think it would be strong enough to support a 2000lb bar being dropped on it from a 2m height without breaking? I want to build it without welding, but am concerned over the strength of such a box connected only with kee clamps.
though that page doesn't seem to be quite complete
