I use a chamber mandrel that’s 3d printed it’s insulated up to a certain point so it only cuts certain areas of the barrel depending on what mandrel I’m using. For the roundness though of chamber end on the outside lip. That comes naturally when I’m boring out the barrel initially
@EGM-hv8mi excuse my ignorance, but do you have any links you could maybe point me to, which show a 3d printed mandrel? I'm just a little confused on how that would work. Chambering for the 9mm seems to be the biggest issue I foresee and could almost just have me trying to use 380 instead.
What's the base product? Is it a pipe thats a part of some kind of water heating contraption, a car, a bike? It surely can't be to hard not to crack, neither soft to let the bullets wear iy down. Whats the best option? I live in europe btw.
It’s 170,000psi hydraulic seamless tube. You only need half that to perform safely this is double what you need. If you have AliExpress, bangood alibaba also sells. It’s not illegal to purchase this tube you need or raise any red flags
Can anyone please tell me what should be the barrel radius for any 9 mm bullet. When i see 9mm cartridge they seem to be bigger than 9mm diameter I'm asking this because t never got see any nine mm cartridge in person
My gun was milled in the chamber area when i left the Spanish navy . Could i somehow weld a curvature picee of pipe or a pice of similar steel back to the milled chamber part . Im a experienced tig mig welder i know i could weld it and make it look as if nothing happend. But i want to know if the pressure of the 380 cartridge will hold ?
Thanks! Yeah that was my 4th or 5th 9mm barrel I done using ECM process and printed jigs takes about 1-1.5 hours
A pure miracle is what that is. I just KNOW you are over the moon with this result.

*hey that's pretty good*
Just curious, but what do you use for reaming out the chambering for the brass?

For 9x19 lands diameter 8.82mm grooves 9.02 and chamber 9.680-9.931 i would buy 8.8 inner diameter tube then rifle it and chamber
What kind of steel is the barrel?
160,000 psi seamless hydraulic tube
@EGM-hv8mi great job, would you mind sharing the dimensions of the hydraulic pipe? Thank you.
