Consider the pervasiveness of data collection on firearms enthusiasts through government/corporate surveillance; any purchased component of something that is weaponizable is an automatic leak/red flag to the system.Your precious hydraulic tubes are all being watched and recorded as to who is buying them.This begs the question; are you a bad enough dude to forge your own barrels? How about homemade metallurgy and casting? Treatment of existing shapes to make them strong enough to withstand pistol pressure, let alone rifle pressure? If you can't source your own barrels in a way that doesn't arouse suspicion, then attempting avoiding surveillance through manufacturing your own weapons is impossible.Until this major hurdle is addressed, those championing 3d printing of weapons as a meaningful tool of political resistance are totally unserious and are shilling you gadgets.Also unaddressed is mass production and raw materials sourcing, enough to arm and supply a squad, let alone a platoon or battalion.The real force is not merely the gun, but the logistics behind it that deliver and supply more ammunition to enable it to keep shooting.
>>65042952Primers and gunpowder are bigger bottleneck that basically relies on an industrial supply chain to get anything in quantity that's relatively safe and consistent.But yeah, I think 3d-printing is more of a toy to experiment with polymer receivers. The Luty and Sten have been around for decades. This stuff isn't rocket science.
>>65042952Starting from something like a drive shaft is probably your best bet.
>>65042962>Primers and gunpowder are bigger bottleneck that basically relies on an industrial supply chain to get anything in quantity that's relatively safe and consistent.This is true; however, the potential alternatives are wider and more immediately accessible for primers and powder rather than barrels, due to the sheer scale of manufacturing required to supply an army of a meaningful size.>The Luty and Sten have been around for decades. This stuff isn't rocket science.But it is. Most people have no idea what steel is made of, or what or how to test its fitness for purpose. Most residential or commercial electric utilities in America don't supply the power necessary to run any sort of machinery of consequence.

>>65042952>Until this major hurdle is addressedIt WAS addressed you fucking numpty.ECM rifling and chamber cutting.That's how the FGC-9 barrel is intended to be formed, using any pre-hardened steel tube.https://www.thefirearmblog.com/blog/2019/08/13/make-a-factory-quality-9mm-rifled-barrel-in-your-kitchen-using-salt-water-and-electricity-ecm/This was solved in 2019.Quote from link for you specifically:>This project was named “ButWhatAbout: Barrels”, as a sort of middle finger to the brainlets who felt the need to ask “But what about the barrel? How are you printing that?”
>>650429521045 steel has massive amounts of tensile and toughness for gun barrels, round stock is anywhere you want because its used in everything from axles to gears and impact toolingIt is so easy to heat treat even the dumbest gronk can do it with a fan forced charcoal pit fire, water trough and home ovenThe only dumber thing is a metalwork lathe, these are everywhere, small-big as you want at dozens of price points for anyone's budget. You really don't have to be very smart to use a lathe and the only real sticking points are attention to detail, run speeds and measurements, for something like 1045 unhardened you can get away with cheap, easy to use HSS cutters.Barrels are some of the easiest things to make considering all the other moving parts that go into a gun that do require a lot more precision and comparative strength
>>65042962ThisAmmo purchases in my country are only possible if you have a gun ownership license card, and all your ammo purchases are marked on the cardI could print whatever I want but it's useless without the logistics support to run it

>>65043278You can get a 10kw 240v circuit installed in your home easily in the US. I have two.
>>65042964Driveshafts are hollow.
>>65042952You don't need 16mm explosion proof tube, it was just chosen as the best of easily available. The new hotness is ecm bored bolts. Or you can use more common pipe, as mentioned the main issue is primers. People are working on recipes for diy versions though, you could help fight gun control if you wanted.
>>65042952This was figured out way before 3d printing was around. People are fabricating silicon chips in their shed for fun, you think basic metal fabrication techniques from a century ago are a roadblock? Maybe if you spent less time watching other people do shit you would realize that you really can just do shit.
>>65044040Okay, I swear I remember front wheel drive cars having a solid driveshaft, but I am going insane trying to find a photo of one and google is just giving me ads for custom driveshaft fabrication services.
>>65042952>if you can't mine your own iron ore you can't make your own barrels, checkmate printfags!>t. roastie soijak.
>>65044204I think a solid drive shaft would be pretty pointless in a passenger car. You want the drivetrain to be as light as possible, to minimize parasitic lossesMaybe in applications with extremely high torque, but then I think the clutch would almost always fail before even a hollow driveshaft
