Patent no way - I spotted that cordless tool battery powers now enable
drilling sockets for feathers&wedge.  Everything familiar already - it's
just reaching a "cross-over point" where becomes economic.

I asked because my hoisting tripod top connection is standard hardware store material arranged in a way I haven't found elsewhere, that leaves the legs free to move in all directions when unloaded but locks up rigid under load. I think the upper leg attachment counts nearly as pins equally loaded at both ends but due to the odd geometry the calculation is beyond me. The foot end is almost a ball joint, again using standard material.
Recently I bought a 2000Kg crane scale that will let me proof test them above the 1000Kg (2204 Lbs) that they support with no sign of stress.
It cost $90 and matches the 1000Kg scale within <5 Lbs at 1500 Lbs, so far.
