Electro-Chemically Machined Barrel ( lemmy.world )

The tools required to manufacturer rifling in traditional ways are highly cost prohibitive. Electro-Chemical Machining (ECM) is a method where it can be done for very cheap.

ECM is used by employing saltwater, an electric current, and conductive material to rust groves into a blank barrel in a controlled manner. This conductive material is wrapped around a jig (like shown below) which is then placed into the blank to guide the oxidation, and form rifling.

Traditionally barrels are made by cutting, forging, buttoning, or broaching.

Rules:

**1) Treat Others in a Civil Manner.**This is not the place to deride others for their race, sexuality, or etc. Personal insults of other members are not welcome here. Neither are calls for violence.

2) No Contemporary PoliticsHistorical politics that influenced designs or adoption of designs are excluded from this rule. Acknowledgement of existing laws to explain designs is also permissable, so long as comments aren’t in made to advocate or oppose a policy. Let’s not make this a place where we battle over which color ties our politicians should have, or the issues of today.

3) No AdvertisingThis doesn’t apply to posting historical advertisements.

4) Keep Post on TopicThis rule will be enforced with leeway. Just keep it related to arms or Forgotten Weapons. If you feel you have something that’s worth posting here that isn’t about either of those (and doesn’t violate other rules) feel free to reach out to a mod.

5) No NSFW ContentPlease refrain from posting uncensored extreme gore or sexualized content. If censored these posts may be fine.

Post Guide Lines

These are suggestions not rules.

-Provide a duration for videos. eg. [12:34]

-Provide a year to either indicate when a specific design was produced, patented, or released. If you have an older design being used in a recent conflict provide the year the picture was taken. Dates should be included to help contextualize, not necessarily give exact periods.

-Post a full URL, on mobile devices it can be hard to tell what you’re clicking on if you only see “(Link)”.

-Posts do not have to be just firearms. Blades, bows, etc. are also welcome.
