i don't have any pictures but i've had a few spud guns over the years. I had a pneumatic gun with a sprinkler valve and a 4 foot by 1.5" barrel first, then i made a combustion gun with a 4 foot 2" barrell and a rifle ish looking one with a 1" barrell and a silencer for shooting super balls

 

[Benjo]

do you like pneumatic or combustion better? i prefer combustion

 

[jr dragster T]

I prefer combustion when they stay in one peice. I built one from ABS (Told it was fine and used by many) First fire on Alcohol it cracked in a bunch of places.

well i've had reliablilty issues with combustion with the electrodes getting coated in carbon. as to the explosion problem, my pnuematic gun exploded at 100psi when my friend was pumping it up. so apparently they both have problems

 

[Benjo]

your pretty lucky tyler, it could have exploded and seriously injured you.
