Progress pix taken in my friends shop.
The main straps are 2"x1/4"
The diagonal supports are 2" square seamed and I can't remember the wall thickness.
The lightening speed hole tubes aren't welded in yet.
I'll get them powdercoated before they go up, maybe Ford corporate blue or charcoal gray.
These supports are 24"x24" to hold a 40' long x 26" deep mezzanine/shelf going up on my back shop wall above the windows.
With the guesstimate eyeballing, I'll have 22" of height in the back of the shelf and 38"+ in front.
Plenty of high storage and an easy place to hide wires and air lines, and wire up the 3 LED shop lights I have left.
7 angle supports total and yet undetermined attachment and support on each end if it needs it.
Each support will be mounted on a post/pole that is the main frame of the building.
The posts are laminated 6x8s.
