Anyone have a instructions on how to build an electric arc engraver?
I want to build my own electric arc engraver similar to an Actograph or a Martindale. Not prepared to spend $400+ for one. Not the vibrating kind like a Dremel but one that burns into the metal. Had one at a shop I used to work at but I never got around to copying it. I recall that it was fairly simple--a hunk of plywood with a metal plate with ground wire attatched & a heavy duty cork insulated cord with copper tip as the business end. Any info would be appreciated.
