Description

The primary purpose of this group is to support those who are building the EDM (Electrical Discharge machine) described in: The EDM How-To Book written by Ben Fleming.

Individuals wishing to discuss other EDM designs and design concepts are welcome to explore those ideas here as well.

The rules here are simple, be friendly and respectful of other builders, off topic (i.e. non EDM related) or personal attacks will result in being banned from posting.

This is a photo of the PCB (Printed Circuit Board) that is now available. Using the board considerably reduces the construction time of the power supply.

The PCboard is available for $25 which includes postage.
The EDM How-To Book sells for $30 which Includes postage.

NOTE: Both quoted prices include 1st class postage(USPS) shipped to any U.S. Address ONLY.

If you live outside the U.S.A. E-mail
bnf@mail.uark.edu
for charges to your country.
