hey I made one and i thought it could help you making your own. It is very simple, i use a 16grams co2 bike pump with manual regulator, a blow gun rated to 12 bars, and the barrel is made from a 14/16 aluminim arrow and is attached to the blowgun via a homemade adaptor, using a pen and bondo paste. ...

buy some .177 BB's, put a piece of cotton, put some bb's next to it, then a light piece of cotton, and shoot at water!!! see the bb's spread, this is fun, and doens't hurt nothing. i recently made a semi auto .177 spudgun. shoots at 200m/s.

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...

Pneumatic copper spudgun.

This is my second cannon. It hasn't any particular name. It is made out of copper and PVC. Here in france we haven't sch40 pvc and i didn't want to spend extra money buying it from another country. The air tank is a 20" x 1.5" copper pipe, which is stopped by a 1.5" elbow and an brass endcap. all th...

When i shot water, it was usually with no barrel, i was just filling the valve with water, then shooting, that was hitting pretty much. 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?
