ya the next ,full scale one will have one, and also im going to mesre how much pressure one square inch will make and calculate maby like 100 psi or whatever

no not really ive built two basic combustions and one phenumatic that runs of water and dry ice , and ive done reasurch none on the web I could find listed any info about the cylinders pressure, and by meterpipe i'm assume its the pre measured metal pipe inbetween the two ball valves in order to get...

ok found the calculat n burnt but I dont know what the supply tank pressure on the bernzOmatic propane cylinders are and I also dont know what it means by fueul mixcher and lastly what does it mean by " meter pipe" ?! sorry about the spelling and thanks for any help in advance -------AL

any body know how much pressure per square inch dry ice makes its long shot but thanks anyways

awesome thanks im gonna go chechk out burnt now see ya

ok guys sorry but ive tryed to figure out how to figure out the square inches I need but I couldent to fintd the ideal amouthn of propane I need if any fellow spuders could help me out It would be greatly appreciated dimentions _ chamber is 24 inch long 3 inch pipe atmospheric pressure_ 30.06 inches...

hey I made sorta the same gun but instead of boiling water use dry ice it works 100x better

nope I figured what the heck its rated to like 600 psi plus it was more like im at the store why not do a simple project

ive got an idea......... ok so you've all seen advanced spuds, I think cam lever breach loader mod, well how about you have separet chambers with the camlevers and one of those big pvc valves that you push down to let the air out and have the other cam lever part and some thing to push the valve dom...

just made a small maby 6 inch 1 inch chamber dry ice gun with ball valve proto typre and had a very good distance for such a small gun now im gonna go full scale after I finsh my outher project . I recomend a dry ice gun to any one with a easy soource of dry ice ( my parents are chemists )

first off do you think it would work to make a small simple galvanized pipe with ball valve shooter that runs of of dry ice

and secondly do you think it would work to make propane ballons and load them into the chamber as sorta lke a clip?

ya definently go with just a sling shot style

I used lighter fluid and once I took off the cap after fireing I sparked it about 3 feet away and the un burned fumes aand fluid carried back to the gun and lit whole gun and my hand on fire (no injurys tho)
