OK, this is largely beyond anything I'll ever do, but I post it here because it's interesting to me, and it's something I've wondered about.

I've only read the first page, so far, but I'm guessing quite a few of you will find it informative. This is how they make those spiffy, neat holes in ported barrels, for instance.

That was a good read. Thanks for posting

FYI, that is also the method used for cutting flutes in Hk / CETME chambers...

This is an excellent manual as a detailed overview. I used it with my students as the class text. Very well written by people who do this for a living. The price is also unbeatable. FREE!

I have copy of "The EDM How-To BooK" by Ben Fleming. Detailed instructions on building and operating your EDM machine. He also makes and sells a PC board for the electronics components. Going to order one if available. Although I don't know that I will ever get around to building an EDM.

I got the book from Lindsay Publications (www.lindsaybks.com) an outstanding source of books on all kinds of old technology, as well as simplified do-it-yourself methods for home workshop applications of newer technology. Want to build your own lathe or milling machine? Lindsay has the info.
