I currently have a simple breech on my cannon (a hole cut in a 1" pvc barrel w/ a piece of 1 1/4" pvc and electrical tape to seal it) and I was wondering if there was a way to put in a simple magazine. I was thinking of mounting a plastic chamber w/ a pvc pipe in the bottom that was somehow mounted on the outside of the gun w/ the pipe about 3/4" above the breech so that when I slide the breech forward the ammo(bouncy balls) drops into the barrel and I will make it have a spring action to slide the cover back over the hole. Does any1 have any suggestions on how to mount the magazine or does any1 have any better ideas that I can use w/ my current breech. Any help is much appreciated.

you could hollow out a tee and attach a pipe to it, then just turn it so it drops in the hole, then to seal it just twist it back.

if you need a diagram i can make one.

this didnt exactly turn out the way i wanted it to, but basicly the tee is dremeled out (with a dremel or simular tool) to the point it slide over the pvc. you first have to take out the loading mechonism (if thats what you want to call it), then slide the tee over it. when you are going to fire, you simply turn the tee so it is not lined up with the hole, then you just turn it back to reload.

note- i havent accually built one, so i cant garentee it will work.

electrical tape is okay, sometimes you have to take it off and redo it but it works. I'm going to try o-rings soon so I'll let you know how that works
