I'm concerned about the stresses on the boom, but I plan on using 3 bails to spread the load. I've looked at the threads with the bent and snapped booms. I think that both booms were fairly thin walled oval shaped booms. Mine is an aluminum
pipe that I think came off a North Sea oil
derrick. I'll get exact dimensions, but it appears to be approximately 5-6" in diameter, with a wall thickness of 3/16-1/4". With the loads spread over 3 bails, and possibly a boom brake
, I feel pretty confident.
