Propane magazine
Posted: Sat Nov 12, 2011 6:38 pm
I am in the process of building a somewhat compact tennis ball launcher and would like to hide the mechaincal parts of the launcher inside the stock I have constructed. I cant seem to find the smaller propane cylnders some members have found, so instead of using a full size propane cylnder I want to make a resivor of some sort or a magazine if you will that I can refill myself. I havent seen anything like this yet as most folks seem to use a whole 1LB tank. I was thinking of cutting down a cylnder and welding it in the middle or something to that effect. Even a pipe nipple would work as long as I could get about 50 shots out of it. Some research has told me that I need a cylnder that is capable of delivering liquid propane like a camping cylnder or a non-OPD cylnder but thats about all I have found. The stock is 3" PVC about 20" long and has to hold a fuel source, power source, regulator, meter, and ignition. I have constructed a few launchers and this is more of a challenge as this is the first one where size is a concern.
