wow yeah sorry theres probably no way for that to work well, unless you get a couple of scuba tanks. thats completely impracticle so ill agree w/ benstern.....forget about it

Ohh yeah missed the marble part....that's what I get for websurfing during sociology class .

Yeah in that case 1'x5" isn't going to do jack. If you have your heart set on marbles, you'd prolly need at least 500 cu in of chamber volume. Or a scuba tank . On a serious note, one of the compressors with tanks used for pneumatic tools might do the trick, but 12" of 5"....Dare I say it, you've lost your marbles

couldnt i just slap a gravity fed mag on a pneumatic with a HUGE tank???

Yeah I guess that would work, I don't have much experience with MGs but I think it might need a vortex block, good luck finding/making one for marbles.

a vortex would eat a ton of air. too much

correct me if im wrong but i have heard vortex blocks consume less air than a cloud. My vortex bbmg works much better than my cloud. but its true making a vortex block for marbles will be a challange. mopherman, before you build your marble mg i think you should plan on it not being portable unless you invest a lot of time and money in an original design.

its not gonna be a cloud OR a vortex. its just goning to have a gravity fed clip on the barrel. like this
