alright me and a comrad are intrested in making a pipe cannon, the propellent we want to use is a powder something that is not too lavish and complicated. also something that is not so powerful as too if we added too much that it would explode when lit. i was think of something like smokeless powder. what kingd of pipe should we use pvc or metal we can get aluminum. also a cap we used a 2 liter bottle cap as the plug and lots of tape. any comments and/or suggestions? please comment.

Even though I personally do not make cannons.....

There is a good page on metal cannons here: http://www.powerlabs.org/cannons.htm

Copy... paste. Copy, paste. It's easy! His name is Slithzerikai and that's how it's spelled.... I don't think you are being a poser, however, just because you call a friend a comrade.

ok i have a new cannon it's a steel pipe about 16in or so long and about 1/3 to 3/4in ID. i am making black powder my kno3 is being ball milled as we speak. my charcoal is aspen, i am using kitchen match sticks for charcoal. i am having trouble getting sulfer though. can i make a propellent without the sulfer?

anyway what are some good ratios for a cannon. i want to lauanch a taped up battery pretty far, ant comments are appreciated.

Let the flame war begin!

Okay here's another idea no one flame's anyone and we keep this thread about cannons!

Okay I suggest make the battery a tight seal so you hafe to push it down (dosen't slide down) and use lift powder. Just my 2 cents.

I made a crappy, cheap, 5 minute pipe cannon once.

I took a 18" piece of steel pipe (about 1/2" ID) and drilled a hole inside. I melted a lead fishing weight and poured it down to form an endcap, making sure it didn't fill my fuse hole. I poured about a teaspoon of BP down, stuck in a cotton ball for wadding, rammed it down, and dropped in a AA battery (it was too big for just the battery).

I propped it up at a 45 degree angle, lit the fuse, and backed off. With a loud whump, it launched the battery through a small tree branch (1.5")in the way, and far enough out into the water that I couldn't see a splash (at least 500 yards, I'd say). The recoil cracked the rock it was on in half.

I then tried it with an aerial flare from an expired launcher (which fit perfectly), so I could see the progress. It reached at least 1,000 feet. About 5 minutes later, a Coast Guard boat came by, wondering what was up.

It was worth the 15 minutes

any propellent ideas?

has anyone else made something like this.

I would recomend NC as it is very easy to make and only requires a very small amount of NC for you to get good powder and range
