simple breech loading for small barrels
Posted: Fri Jul 14, 2006 3:39 pm
i had some left over parts and i wanted to make a simple breech load barrel for my marble cannon. you just take a half inch coupling with the little rim in the middle drilled out and slide it on your barrel to where you want it. then just drill a hole the size of your usual ammo (marble for me) through both the coupling and the pipe.
you may want to add o rings too on the pipe where the edges of the coupling will be but i didnt bother because its a barrel so it doesnt have to hold the pressure perfectly. it doesnt leak very much for me without them.
now after you lube it up you should be able to twist the coupling so the holes dont line up. thats the firing postion and when they do line up is the loading position.
