that's it!! There is no pressure inside the chamber cuz the only pressure involved in this creation, is the one from the compressor, used to ighten the speed of the air going through the chamber, doing that, you create a venturi effect, air is accelerated when passin trhough the barrel, so, the air ...

Well i think I know how to solder, but you know, my parents aren't particularly ok with spudguns. I think you need to heat the copper up to 600 °C or so, and then you can join the parts together as the metal will stay glued on copper. I have a propane torch, but my parents wouldn't let me do it. whe...

I never used a sabot when firing water and it always shoot a giant burst of steam. with 1.5 " marbles, the recoil isn't stronger, i said something wrong. even with ...

i'm wondering how much pressure a 28mm of diameter copper pipe can handle? Cuz i actually have a soda bottle with glued diaphragm valve, and i put it to 60-70 psi, even at these pressures, recoil is substantial and with water, it breaks you the arm!! so how much pressure can 2mm thick copper handle?
