Nick, Absolutely fantastic! Greatly appreciate the pictures also! I started building mine about 9 months ago, but wasn't happy with the way my "perf board"...
Nick thanks very much for posting the Photos on how to make the PC Board in the photo section. I think it will be very helpful for many builders. BTW you did a...
When I did PCBs for projects, I used to use a small aquarium air pump and a diffuser stone in the Ferric Chloride Solution to agitate the solution. The little...
I just picked up Ben's book today. It looks very interesting, and fairly similar to Robert's design. I'll study both, and try to come up with a good mix of...
Wow Ben, That's a great book you have there. Basically being very cheap too, I wasn't originally going to purchase your book, as I have the Home Shop...
Bob, To agitate I used a hot air gun gently blowing over the surface of the boards, or a hair drier would be okay. Not too much heat though ! For the limited...
... Ben, I'll wait to see if it works before accepting any praise ! and will post more photos of the rest of the panel soon. I have a few questions for you : ...
The main reason I chose Fiberglass for the dielectric tank was to reduce the tendency of electrical shock and to insulate the EDM power supply circuit from...
Nick I failed to answer your question about the 48 Volts. It has been my experience that and EDM will work with a 48VAC output but it is on the edge. I would...
Thanks Ben, I've now found a Toroidal transformer with 2 x 35V outputs which I can wire in series to give your suggested 70 Volt output. It's physically...
... Actually, a 240/208 VAC to 120 VAC isolation transformer is a good choice here, but remember the output CURRENT is the limiting factor, not the power. The...
The standard domestic supply in the UK is 240 volts, at 50 hertz. Matthew ... http://www.surpluscenter.com/item.asp?UID=2006090511125216&item=15-1150&catname= ...
... Sorry, I'm in the USA where it's 120. But a 480-120 transformer should work well. David G. LeVine Nashua, NH 03060 -- No virus found in this outgoing...
Matthew, a few years ago they dropped it from 240 to 220 volts in the UK , and where I am we are lucky to get that ! Regards Nick ... From: Matthew Tinker To:...

I've added a few more photos showing my PCB in the enclosure with the separate capacitor board. I could only source 10uF Polypropylene capacitors for C1 and C2...
Thats what they call it! when I moved to France nearly thirty years ago, they were calling it 220 when it was approximately yhe same a the UK. In the early...
Having completed and tested my PCB and panel I've uploaded the drawings to the files section in dxf format which can be imported into most CAD software...
Ben, I find that with around 54VAC everthing works well, all the voltages at the DIP sockets are as stated in the book and I have good control over the servo...
Nick I am shooting from the hip right now as I am at work and don't have the schematic in front of me. The problem is the voltage at the top of the window...
I just ordered a tank today. It's part # 51084 from US Plastics. It measures 23-1/2 X 16-1/8 X 10-1/4 deep, it's a few inches deeper and a little more than...

Hi Ben, I have a piece of aluminum diamond plate about 1/4" thick, without the raised diamonds. I was thinking of adding some aluminum feet to flats machined...
Ben, What was the small tank you had on your setup at the CNC Workshop? If I remember correctly, it looked like a grey PVC Electrical Box. Any additional...
Ben, Many thanks for your reply, it's great to have some advice at times like this. Nick ... From: Ben Fleming To: EDMHomeBuilders@yahoogroups.com Sent:...
I know people that have used water. I have played around with it a couple of time. The biggest problem is the water becomes conductive quickly and it involves...
