I know a guy, a genius in his own right, a bit of an oddball as well, who made a test light out of an old screwdriver. It had a transparent orange handle which made a beautiful glow.
He, of course, ground the bit end to a skinny sharp point. He then cut the end of the handle off, drilled the interior of the handle, and somehow created very neat threads on the inside. He then cut the end off of another similar screwdriver handle and threaded it to fit. He soldered a wire to the shaft inside of the handle to add the light bulb and a wire with an alligator clip on it which passed through the cap.
My words do not do justice to the quality of work that went into the creation of this tool. I did not know Paul all that well. He was very secretive of his past. I suspect that he did some time in The Big House, and may very well have broken out of it.
I informed him that I was very interested in buying it from him. He informed me that there was no amount of money that he would take for it. He probably used it to crack the electric lock on his prison cell or something like that.
