OK guys need some help thinking through this.
I am trying to determine what would be the best material to make the canopy frame out of?
My original thought was some 1 1/4" square tubing but after adding up the weight for a 42" X 60" frame that adds almost 45 lbs. to the top bringing the total weight of the removable pieces to 77 lbs.! /forums/images/graemlins/blush.gif I think that is too heavy to be man handling while strateling the 3ph!
So here is the question:
With tubing strength is it stronger to go with a smaller outer dimension tubing with a thicker wall or a large dimension tubing with a thinner wall?
I will either be using 28 gauge sheet metal or canvas for the top so it would be a max weight of 16 lbs. spread over the area of the frame. That is not the problem as much as the strength needed if I decide to leave it on while driving down the road. The mounting brackets and gusseted uprights will be plenty strong. The frame is my concern.
Attached are the plans for the mounting bracket.
