NW Washington | Wow, 4x4 quarter wall weighs 12.2 pounds per foot. So your going to have one heavy boom. Hope your planning on a wheel boom.
BTW, square tubing is stronger in bending than round., but in this situation rectangular tubing that is higher than it is wide would be better since your main load is vertical in bending. The best way to engineer this project is to copy one that does the job. No need to re-invent the wheel. | |

Pipe vs square tubing for strength?
