you would only get about 2-3 of the balls to shoot out of the barrel per shot(i say this because with sprinkler mods ya cant get dbl trigger pushes YOU HAVE TO SHOOT ONCE THEN FILL AND THEN REPEAT) hardly a final solution thatnks anyways, you are better off designing a spring powered piston valve.

See the jump is no prob, as i stated b4 its only bout 50ft into WATER, thats about 18ft deep, i have done this jump previously without the parachute just jumping but i think that using aforce pushed chute it might improve air time and idk FOR FUn :roll: if it doesent work i wont die i will just fall...

i am making a ghetto parachute to deploy as i jump a 50ft drop from a bridge to water( only reason making the parachute is elongated fly-time) it needs to be powered by some sort of pressure that can be released in an instant, i was thinking paintball co2 but i know there has to be a better/safer wa...

Thanks, but i need to know what to use for a good seal (material) and if it HAS to be filled from behind the piston.

No offence but let they guy work it out for himself if he doesent care about your opinion (he is probably just leting his imagination take over.). Failure is necessary for building character but we will know if he fails because he will be on the news .

I suck completely at tryng to make a piston valve con someboday help me by posting a diagram instructions or something ive looked all over and i cant fing anything very helpfull. I am making a galvanized steel "T" style cannon and i need help making a piston valve inside the t ventilated by a blogun...

One inch in ballistics gel is about a 79 percent fatal hit. The penetration you hit was fkin scary thats a waaaaaaaaaay powerfull "potato gun".

I know. That was the sickest sht EVER. I convinced my dad to help me with a supersonic all metal (large diameter) helium filled golfball barrel. Why the gb barrel? because i found copper balls that fit perfectly.

My dream is to get one but im too poor.

Can you hold your breath underwater 4 minutes. my best was 1 minute 40 seconds and i couldent take it.

Depends on your barrel or wherever the disk is going to go diameter. Pressures are aswell a factor, low pressure paper then alluminium foil and then my favorite for hybrids alluminium can.

EWWWWWWWWWWWWWWWW. I know the pole is over but paint is gold and silver call it BLING BLING. fo shizle.

I dont have my cam till i go to my dad's but on saturday i will. I think the pvc thing will do the same thing but i think that it will be lighter and buoyancy will be a problem. And if you accidentaly smack the plastic tank against something you are risking it but with the steel extingushers you kno...

I wouldent use a bike pump if you want to go over 100 psi, unless you have a really good one. Today after reading this topic i modified it and put a locking system so that letting too much pressure get through wasent a problem. I attached a snorkel mouthpeice to it and put a longer hose. I straped i...

If you just want to mess around i have an idea for you. Once i was in the beach with one of my fire extinguisher guns, well i had the bright idea to return it to a regular fire extinguisher for a day, i felled it up to 150 or so and but some weighs on, the thing is that you have to push the lever ev...
