piston gun vented by a piston valve.

[th3p0p0]

well iv made 3 working piston guns and this is my latest. its a piston valve in a 2" T with a 3/4" barrel a 2" air chamber and the piston is made out of a 1-1/4" end cap with tape on it. and for the vent is a 1" piston in a 1" T with 1/2" porting wich is vented by a 1/4" ball valve. for lube (on the pistons) i use KY jelly. thats the specs now for the pics.

[hi]

nice. little messy, but still nice. is there any kind of delay between when you pull the ball valve open and when it fires?

[th3p0p0]

no they both go at the same time and i have a leak ware the barrel screws in and cant get to stop any ideas??

[hi]

have you tried teftlon tape? if teftlon tape and a pipe wrench doesnt work then there is something wrong with the threads.

I you are 100% sure that everything is well built and will last a long time, then you can put epoxy on it.

first off your avatar scares me. now that we got that out of the way i actualy thought about doing this and then thought you would have to be an idiot to try and make 2 pistons seal perfectly instead of one.(sorry) cool any ways but you should go exteme and make and uber mini piston to vent your second one like piston in 5/16 brakelile with a 1/4 brake line "barrel"

[th3p0p0]

not the threaded part ware i glued at

[th3p0p0]

if it scares you then im happy jk its the o rly owl with teeth. and i may be stupid im not dumb. and i think im just going to keep the 1/4" ball valve.

i always though about something like that. im glad someone actually made one. seems a little overkill but hell its sweet

[th3p0p0]

over kill is good a thing hear this things a beast its very powerful but im getting tired of shooting 12g c02 thingys. is thir any other ammo for 3/4 that i don't know of?

marbles or paintballs their pretty fun for a while

A piston that actuates a piston that actuates a piston that actuates a piston that actuates a... Well you get the idea.

i would just use the ball valve to pilot it... ur probably not getting much more performance by pilotting it with a piston valve.... take the piston off and just use it for another gun.. u would already have the piuston and thats the hardest part of a gun...

design a rifle looking gun...rifles are always cool...


oh and while ur at it u might wanna slap a paint job on that because u didnt do a very good job with the primer

[th3p0p0]

why thank you spud thug it was a throw together gun so i didn't rely care
about primer stanes. im making a new gun today its a paint ball gun with a 3/4" sprinkler valve im going to use 45 and 90 degree elbows to make it look like a real gun and if its accurate ill put big ass scope on it.

i use KY jelly.

For what? lol

The piston + piston is a little wierd, but it could actually be useful. Why not turn it around 180* and make another, smaller barrel that shoots marbles or something along with the main cannon. Traccers?

Or just buy a QEV and conserve space and use the small piston on an entirely new gun.

[lukemc]

for all you people *cough*spudthug*cough* that are saying why didnt you just use a ball valve. im pretty sure he wasnt going for increased performance as much as just being able to say "hey i made...."
