For the bottom area of the tank, I added what I would call a belt loop onto the back of the upright flap motor housing support. 1 1/2 inch webbing fits inside the belt loop. A spacer near the top, and the smoke motor doubler on the bottom provide the necessary clearance for the webbing. I put 5 inches of heavy duty Velcro towards each end of the web belt. It came with strong adhesive, but I also stitched it around the perimeter for holding strength. The belt loop is held with two AN3 bolts into nutplates at the bottom and flush stainless 10/32 machine screws at the top. Flush prevents any interference with the O2 tank when mounted. I also got to practice double flush riveting again for the upper spacer. Now I will route the O2 lines and place clips in strategic areas to support the lines and apparatus.
