Could you share a pdf explaining how you make the cutting solution and power the electrolysis process, please? Also, is there someone from whom I could buy the CNC printed parts? You maybe? I don’t want to learn CNC printing to make a barrel. Of course, since mine would be a16.5” barrel I presume I’d need a longer rod.

My last month paycheck was for 11000 dollars… All i did was simple online work from comfort at home for 3-4 hours/day that I got from this agency I discovered over the internet and they paid me for it 95 bucks every hour…..> https://www.pay.salary49.com

Im making over $28k a month working part time. I kept hearing other people tell me how much money they can make online so I decided to look into it. Well, p it was all true and has totally changed my life. This is what I do.
AND GOOD LUCK.:)

When looking to buy pull-out couches, there are several options to consider. You can check furniture stores such as IKEA, Ashley HomeStore, and Wayfair. Online marketplaces like Amazon and eBay also offer a wide range of choices. Additionally, consider local classifieds, thrift stores, and online classified websites like Craigslist for potential deals.

its cute and all but you still pay taxes to corrupt pedophile satanists and fund false wars. sooo keep it up I guess.

We have no other option for change, in my opinion, so we must use force. For more than 45 years, unscrupulous politicians have controlled this nation. Everyone in government who has served in the last 45 years has baggage. They should all be tried and looked into.I work on my homework. https://netpayfast.com/

Very interested in this method. Any ideas on using 3D printing to produce the "tools" with ECM process to produce usable fire control parts. If the bolt faces and firing pin holes can be cut what about feed ribs? What would the 3D printed "tools" be shaped like?

Just a thought, can you use a spent shell cartridge as a chamber boring tool? My idea is to drill a hole through the case insert a metal rod, insulate the rod and use the outside diameter of the cartridge for cutting?

Man I'm impressed as all hell of what you've done here. I've always thought that barrels would be a quite hard wall to crack for any DIY build outside the US since you can't simply order one online. I have not yet tried what you've demonstrated here ( to be fair i just found out about it from the FGC-9 build) however i'm quite interested in trying that. I have a question or two if you don't mind: Does the hydraulic tubing have to be from a certain spec steel? I'm not sure where i'm from i'd find exactly what you have available but with a quick search i could find a seamless tube 16mmOD 8mm ID from" P235TR1 ( 1.0254 ) " steel. Says it's a non-alloy quality steel for seamless tubes for pressure purposes so I'm hoping it'd work just fine. What I'm worried about it the barrel exploding. Do you know if a good number of barrels were made this way and were successful? Again i'm still amazed you didn't need a lathe to achieve this!

Chrome alloy steel is a safer bet.

Can 6mm 3D printer guide rods be used for boring, chambering etc? According to the description the ones I'm looking to order are 'chromed' - just wondering if that would make a difference compared to just mild steel. Alternatively, can stainless steel be used?

etching doesn't are about the metal. however; the salt used in the water may have to change with stainless steel you can check on the web for the best fluid.

It would be great if you could send TheIdahoanShow guy one of your barrels to do a shooting comparison video! His button rifling method is also about this inexpensive and simple so it would come down to accuracy

If I understand correctly you can't use ecm to bore the pilot hole that the rifling mandrel/electrode goes into? (Or it would take forever?) Therefore you have to start with a thick walled hardened tube. If so that limits the types of barrels you can make, no locked breech pistol barrels because those have to start out as billet for all the tilting ramps etc that go under the bore. And I infer that the precision of the pilot hole is important because ecm just erodes equally on the whole surface -it doesn't even out the irregularities in a badly drilled hole it offsets them to a wider diameter.

You can drill with ECM, you just need a CNC setup to control the drill rate. You clearly have little clue what you're talking about, you can make any number of locked breech actions using a simple tubular barrel - do go take a look at the two-part hi-power barrels. By no means to pistol barrels need to start out as billets - you've got to be able to think creatively to make guns yourself. ECM cuts based on a inverse radius squared function, so it will smooth out irregularities.

Actually I think you do not need a cnc setup. I would put a short tube out of metal followed by a much smaller OD plastic tube. Glue them together, similar IDs. The single negative wire goes down the hole and is solder to the metal on the id. The pump pushes the fluid down the cutting tool. Pressure on the face of the thick metal tube at the bottom of the hole is the highest. Pressure drops going through the gap of the od to id of the barrel. The difference in pressure time face area to lower pressure time metal area on that face is the force floating the tool. The pressure at the bottom of the hole on the face is effected by flow rate. Lower flow pushes the tool up harder. What remains is to guide the tool and balance the weight. Have not gone through the design but as the tool drills a deeper hole it will be getting lighter due to buoyancy and the longer flow around the plastic cylinder means more pressure drop. Both must be adjusted by the counter weight. Their weight could be adjusted by being in the water, using buoyancy..

@ThomasS: Can you tell me the particular requirements for salt concentration, amperage setting and how to determine what should be the inside bore diameter? Or even better send me a link where it’s already written? Thank you.

Does ecm do sharp corners very well? Can you make it so the lands are very thin with sharp edges like a button rifled barred? Is there a conductive uv printer resin that could print an electrode, or could a metal plated 3d printed part be an electrode? Then maybe you could also cut engravings, locking lugs in a slide, other complex cuts with ecm instead of milling? sorry a lot of questions but trying to understand all the practical possibilities of ecm metalwork!

Why would you want stress risers in your barrel when you can avoid them? You can ECM nearly any shape that you can mask off with a part you can print - you don't need to print conductive materials and do a bunch of whiz-bang bullshit to make it work. Please do go actually ECM something before making extreme conjectures.

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.

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

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...

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

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