In this video, I touch on all the components of my rifling setup. Between this video (the most important part of the tutorial), and the tech writeup (linked below), other folks (it could be you!) can replicate my results.

I'm really impressed but I'm of a slow mind, is there some book you can read on this?

I am impressed, I have been EC Machining for some years now. I find high power constant current PSU's (Buck+/-) the best and most consistent.
If You, like I am sure you do as well, know a bit about Electronics, I am currently busy to integrate whole electric/electronic/mechanical setup like the PSU, pump, pressure, temperature, saline conductivity sensor monitoring using PI/Arduino.

Dasvidaniya ;)

P.S.: Drop me a line if You like.

It would be cool to see an all-in-one ECM desktop unit.

Do you think it would be beneficial to cut only one groove at a time, then rotate the mandrel? I guess kind of like ram/sinker edm...

Have you tried a stainless barrel yet?

No, but ECM works on stainless.

Cool AF! Always thought EDM would make great barrels, never heard of ECM.

EDM barrels would be very hard. ECM is where it's at.

@IvanTheTroll: Wouldn't coolant flow control depth of hardness?

I am assuming that SS would cut more slowly with ECM.

So if ECM were used, control of depth is achievable and a finishing button could finish?

I wonder if the electrode holder ought not travel as conventional tooling? Maybe control taper...

Perhaps a slow linear motion device?

Mimic the rifling button. Have barrel concentric with electrodes and one traveling at determined rate and helix... VF controlled lead screw.

@bullmtl: What? There is no coolant flow,

@bullmtl: No, SS has a higher valency than 40CR.

@bullmtl: This process is entirely static. There are no moving tools.
