The picture on post # 30 shows the light assembly- the outer ring is 1.5 " PVC schedule 40, about 1" worth. I took an endcap for the same and drilled a 1/4 inch hole in the center and a smaller hole (for the wires) off to the side. This I shortened just a bit, then painted with KRYLON FUSION (I recomend this highly for PVC) and mounted a 1/4" x 3/4" carriage bolt through the center hole from the inside so the threads poke out the hole... this will be how you mount it. Crush the shoulder of the bolt head into the hole and you will not have it turn on you when you tighten the nut that holds it. Now thread the wires through the smaller hole, place a small socket over the threads to protect them and mount the whole operation into a vice- crush it together (make sure it doesn't cant one way or another) and drill holes at 180 degrees in the lens- drill smaller holes to accept #6 Pan heads x 1/2", mount lens and cut your strap iron to make a mount... pretty self-explanitory, actually... unfortunatly, my camera boogered the memory regarding those images
