Making a Battleship out of a Canoe
Posted: Tue Mar 27, 2007 3:20 pm
Me and my friends are mounting a couple pneumatic cannons that have been specialized just for water onto a canoe when we go canoeing because a) we can, and b) to have fun with shooting the other mebers in our canoeing party.
We're probably going to end up putting in a water delivery sytem so that we can reload faster by threading in a hose barb and a hose with a hose clamp to secure it.
Then we're going to clamp the cannons onto the side of the canoe using C-clamps with rubber pads on the ends to prevent wear on the canoe. The reason is because these aren't our canoes, so we'll have to be careful in how we mount them.
After that we're going to attach the hoses to either one or two 5 gallon water bladders that have been pressurized enough to push water into the barrel when one of us triggers a valve. This allows water into the barrel to refill it. We're using a sprinkler valve from the water bladder to the barrels. This way, when the cannon(s) fire, the overpressure from the barrel goes into the sprinkler valve, which by the way, when you are pressurizing a sprinkler valve the wrong way, it lets the pressure by. That overpressure recharges the water bladders pressurization and allows them to put about the same amount into the barrel after each firing.
Also the guns are fired with sprinkler valves as well, so that me and my friend can move without having to stop paddling long enough to fire.
