Poops First gun

Unread postAuthor: awkward poop » Mon Jun 01, 2009 8:39 pm

Hey guys this is my first ever attempt at making anything like this. umm well the diameter of the barrel is around 10mmish, air tank is a poly riser cant remember diamteter. basically its just a super basic ball valve gun.
i can pump it up to about 100 psi in a few seconds with that cheap ciggy compressor. its surprisgnly powerful ill try get some damage shots for you fellas. the trigger is also pretty basic you can hold it like you would a normal stock just slide your right hand back and pull the back of the little white pvc tube thingy down to release the zip ties tied to the ball valve.

O yeah and i usually shoot 1cm lengths of chalk fits perfect in the barrel

Reminds me of a flintlock rifle, so points for that. I'm glad that since you went for a ball valve you at least make it spring fired.

any comments telling me how i can improve this would be muchly appreciated.


Lose the tape first of all. Replace it with hose clamps.

Get a new spring. Yours looks rusty.

*Bonus*
Upgrade to a piston valve exhausted by a blowgun. Then route the blowgun through the stock to have a more realistic trigger pull.
Use the search for how to make a piston. Piston valves are better than ball valves.

yeah piston valve is more good than the ball valve
i had experience this ,i had a ball valve with strong spring lot stronger than yours ,the open was fast ( but the piston valve is more faster) but, all the gun shacks ,effect the accuracy
