Ben, my name is Paul Fournier and I work at Texas Instruments Inc. in Dallas. I just received a copy of your book on the EDM machine. I read it last night and finished it tonight. I have to say that it is a pleasure to read a technical manual that is written as good or better than I could have written it! Step by step on all parts listed. Thank you and keep up the good work. I am looking forward to buying more of your books if you do another one---

This is just a Thank You note and a pat on the back for doing such a good job!!!

Hello Ben
What a great book you have written! My friend Dave Black and I are building a unit now. Dave met you at the Cardinal Engineering Seminar.----I must say, you are a guy that warms my heart with your approach to projects. The drawer slides are a real good sub for fancy ways, and very inexpensive. The down to earth approach is just super! I am a retired Manufacturing Engineer, and seeing this project really wet my appetite. I have built small----"Popular Mechanics" style EDMs for tap busting in the past, and always wanted a servo driven unit now I will have one.

I have now purchased the book, and after reading it, would be happy to recommend it to anyone wanting to build a small EDM. The book is very clear and concise with great instruction and pictures. I am not an electronics guru but I can easily understand how to build this machine. I also want to thank Ben for answering my email questions ...."

Well, despite my best efforts, mine showed up (the EDM book) today. Quite a shock!!! Was not at all the 23 laser printed sheets with side staple binding I was expecting.
A real book with lots of pages and words too. Fortunately for me, LOTS of pictures too. I hope he typed it real slow so I don't have to try to read too fast. It may take some time to digest but so far, I only se a couple of chips which I don't have in my junkbox.

Ben,received the book yesterday, and I am impressed with the detail that I haven't seen since Heath Kits! Thanks for the fine job. I look forward to doing this project and will have some comments later on.

Ben - Just got my copy of the book, and it's fantastic! Though I'd be interested in the possibility of a PC board, I probably won't buy one myself, as your instructions on using the Radio Shack perfboard are so comprehensive (plus, I'm way to anxious to start building to wait for a board or kit).Anyway, the book is great, and I hope you forge ahead with work on a book detailing a pulse-based system.


Hi Ben,
I was impressed with the file being etched. I built ahome-brew R/C type machine and would not even try something so large.
