@luap, the one you made is pretty much like the one that I made, except i only cut one side off to make the window. the first one i made failed so when i made the second after I was done, I heated it up just untill the metal starts to turn purple-ish then dropped it in used motor oil.. basically tempering the metal. Now this tool is sitting in a place I know exactly where it is for next time. It and a cheap c-clamp is all i needed... for the pipe i used 1/2" electrical conduit (laying around)
