it was my first spud gun i built. i had a lot of free time recovering from a hernia surgery. however that's neither here nor there.
now for the info
barrel- 5' of 1" sch40 pvc
chamber-~14" of 3" sch 40 pvc
valve- modded sprinkler valve
pilot- blow gun
fueling- shraider valve tapped through end cap
also a 1"latching coupling
and a 1-160 psi gauge
this gun some how defies all possibilities the valve is only supposed to hold around 140-160 psi yet ive ran hundreds of 180-200 psi shots through it with no problems or bugs.
damage pics and or vids to pop up tomorrow lost all my good ones.
hint flashlight through plywood...
you might want to consider putting a burst disk in that camlock fitting to boost performance.
