Thanks to some work by a fellow reprapper that caught the eye of Hackaday and got nailed for it, we have an introduction to electrochemical machining.

This is a way I hope will provide a support machine for our trickiest hardware. By using a three axis stepper board and a constant current and pump control "extruder board" we can do a stepper spindle controlled CNC lathe . Reprap plastic components would be ideal since the current paths must be controlled. Tank and filter design may be the hardest part. I'd think that a stainless steel industrial needle would make a great drill/mill bit for high detailed parts.
