NOS i'm assuming wouldn't be cost effective,... but dry ice, wow now we're getting somewhere. is that stuff cheap? someone should try it let us know if your still alive afterwards...

[quote]does anyone know of an adapter from 12 gram threaded to 88 gram?

wal mart sells the 12g to standard paintball size,maybe 88 fits? i think they (88's) come with an adaptor so there you have it... 8)

Thanks for the link jack, looks great, and i may do that, the major detractor is bad air efficiency, and since co2 isn't free and requires a 20 mile drive for me, i was hoping to find some type of piston type gun, since we've potentially got access to some serious equipment, including a cnc milling ...

like the title says, i was talking to a buddy yesterday who works part time in a machine shop (you can tell where this is going :D) he says he is allowed to use the equipment after hours or what not, we got to talking about what to create, a series of 50 or so loud bangs bounced through my head, but...

ok so here's the refined version that i (crudely) put together, i took jsr's idea for a valve to pulse the air inlet and it ran like a sewing machine for about 5 seconds, then my epoxy let go and the valve exploded across the room :shock: Don't tell jsr but i may have to stop using that stuff :P i p...

JSR, shoulda mentioned but i'm going for full auto do you think this would cycle? maybe i should just scrap the idea, i know how everyone fells about spoonfeeding but maybe you could just save me some prototyping and point me in the direction of a good auto bolt design ::worthy:: [/quote]

ok, this one has probably been done before so go easy on me if so, i would like to build this one if you guys think it would work let me know if you see anything wrong with it, other than the cheesy stock i added in paint

Thanks, i was kinda looking for specific ideas on feeding it though, i've thought about something like a pill bottle with a rotating "wheel" spun by a dc motor at the bottom having several bb sized slots at the edge that would line up with a hole in the bottle several times per revolution, basically...

you guys think it'll work when i get the tee put in? any suggestions for a high cap mag or loading system? i kinda built this as a proof of concept type thing but since it appears to be a success i wanna add some ammo

thanks jsr, sorry about the crappy quality i hope you guys can figure it out

it says my extension is not allowed? does that mean its too big?

eek sorry guys thought i had it posted right, maybe i am a newb! i'll try again its kinda a variant of the swanstrom.

first post but i've been lurking awhile, first off i've built clouds before, i'm not a total noob but i decided it was time to step it up and do a piston gun, i started looking at the swanstrom design and started working on it but mine took on a style of its own 8) i made a working prototype except ...
