spring forced and penu powerd auto fire plans!

[zeigs spud]

Frow these plans the cannon shoots marbles and hopefully there is enough air force to have enough time for alll the marbles to go through, or at least most.

comment/questions/explanations? plz no flamers.

i think this is good but i would leave the magazine out of it. I have never though of this and it would make a good design. Its like a coaxile.

[zeigs spud]

that is exactly where i got my idea. well the pressure chamber goin over the barrel part atlest. (just for more compressed air to put in.

[saladtossser]

dont waste a sprinkler valve on that, it makes the process harder, i'd rather make a piston out of a pipe cap

[singularity]

okay im a little lost, is it like a coaxile with a spring fed magizine? except your going to put a sprinkler valve inside the chamber instead of making a piston/ diaphram for it, right?

[MrCrowley]

theres a cannon on spudtech with a sprinkler valve inside a coax

[zeigs spud]

all it is is a pretty much the same as an over under cannon but this has a spring filled magazine and the pressure chamber thing is over the entire gun is all.

[schmanman]

yeah, go with an end cap piston, and ditch the magazine.

[zeigs spud]

endcap piston. i've heard of pistons on spud cannons but i don't really know what they do or are for.

read the whole page, It explains it all

When i read the title i thought it was gonna be another wanna be semi-auto, fooled me. I would like to see this built into a mini, and use bb's for ammo.
What do the rest of you think of a mini built like this?
The smaller the better!

[schmanman]

a mini built like this would be pretty cool.

[zeigs spud]

hmm..okay that clears piston stuff up. so then is a piston one better than just an over under normal penu? From what i read it seems like it would just be giving a quick 1 burst of air, if so then that wouldn't really work for my auto feeder cuz it will take around 3 second mabey for it to feed the majority through. i want it to be automatic but it seems from what you're thinking its just so you don't have to re-load as much, which i could be used for lol.

[schmanman]

yes, piston valves are much better. did you click the link in the last description? It shows another piston valve design.
