Essentially this is a vibrating engraver driving a commercially available electrode into the metal. An electric spark eats away the metal, leaving a clean hole. A great machine to remove broken taps. Ever try to drill one out? Good luck!
The disintegrator is built from commonly available materials. A lathe or milling machine is not required.
You get details on assembly of the vibrating head, electrode selection, fabrication of the water flow device, details on using an arc welder as the power supply, and much more. The prototype cost $275.00 with all new equipment, and that's a lot less than $7000 for a commercial unit. With a little scrounging you should be able to put one together for a lot less than $275!
Again, if you don't need a disintegrator, the ideas and info here should be useful in investigating ECM concepts. Very unusual device. Small but excellent booklet. Well worth its small price.
Here's what J.I. in Fort Worth, Texas writes:
"I built Benjamin Fleming's metal disintegrator and use it often. I work as an automotive machinist and broken bolts are an occupational hazard. I still drill them out. (When you're good, you're good.) But those that clumsy mechanics have broken off - taps, drills and (the notorious) easy-outs - are no longer beyond salvage. I fire up the "tap burner" and before you can say "thanks. Mr. Fleming". it's out. I then get to say "that'll be $25.00", which is half the going rate, and split the take with the boss. So far, this machine has paid for every book I have gotten from you and I hope to make it build a much bigger library. . ."
8 1 /2 x 11 booklet 34 pages well illustrated with photos and drawings.
