Andy,
I have been experimenting with EDM long time ago, say 25 years. I used a
simple RC-circuit together with a "soft" transformer (ca.1.5 mm air gap)
in order to forgive for the shorts and save fuses. All was mounted on my
drill press. I gave up when I realized that without a controlled

I think that it shows promise, but only partly works.
I am using a 50R resistor and a

A common thread here seems to be that my 1000uF electrolytic i
There might be some gems in this video? I have an interest (presently on hold)
to make a wire edm so have been collecting information etc.

There is also a Polish forum where someone describes their power supply as well
as details on how they use

Andy,
Check out this page:
http://mikesworkshop.weebly.com/a-spark-erosion-apparatus.html
Also Model Engineer's workshop had a 4 part series on building one. I'll go
through my archives and see if I can find them. I'm pretty sure I had all 4.
An online search doesn't pinpoint which issues.

HI Andy,
There's also this.

Rats. I'm missing #169 for some reason.
The series I was thinking about was in issues #57..#60 and with addendums in
#64 and #68. The #68 issue discussed dielectrics safe for the home workshop
and the liquid mentioned may still be available in the UK.

Issues 1 - 163 might be available on some of the darker areas of the
internet if you can't find them legally. A quick check at the Jolly Roger
one lists them.
