Does anyone know anything about electrochemical machining?
Make EDM thread if you like. Lots to catch up since Russians invented it over 100 years ago. There are many DIY setups but not a whole lot that can be found in one place.
Since this is 3D printing thread, it goes hand in hand. Not politics but tech. There are many ways 3D printing works, not just filament, but also powder cintering, which I saw would be made desktop affordable and with laser cutters CO2 tech coming from china and under $500, I can see that becoming a choice eventually.is this a good place where we can discuss cody wilson and the 3d printing of guns
Unlike printing plastic joos and kiwis, printing firearms steps the game quiet a bit, because you need strength to go with function. The problem I see is that people trying to print parts to fit guns, i.e. printed AR and AK receivers which were designed to be metal. 3D printing works better with Tec9 where lower WAS plastic and firearm was designed around that.
One dimension of 3D gun printing is that you can replicate parts not just easily, but pretty much anywhere around the world. Granted that many countries, unlike US, classify barrels and other gun parts as controlled parts, still, anyone can design a gun in US and have it printed in Japan ... or Honk Kong.
