Ha with all the planning to get the parts done the assembly was really half-assed honestly. I tried industrial strength velcro (it fell off). Then finally I said screw it, and used 2 in gaff tape to go from the inner edge to about 3" beyond the arc reactor in three places, then taped it to my body in three strips of tape. This is all while the first waves of kids were coming for trick'or'treating so I was in a rush and honestly wouldn't recommend it unless you are smooth chested asian, or shave your chest. Ha. I couldn't fit the assembled thing into housing, so in a pinch I used a biscuit cutter from my set, and it was about 1/2" too tall, but it also gave me some room to play with the tape and the batteries (I used 3 cr2032 batteries in a series). I've seen guys who made a harness out of what looks like suspenders and then put the **** over it. That seemed to work pretty well. and is easy to take off when you get sick of it (from walking around comikaze for three hours with something strapped to your chest). Do you have any pics of yours? I'd love to see how it turned out.
