a fairly small/ basic combustion of mine...

hi · Sun Oct 14, 2007 10:17 pm

This is my newest and latest cannon. its was built completly of scraps that i have laying around, it did not cost me a single penny. the chamber is a 2'' tee. the barrel is about 16'' of 3/4'' pvc. the chamber is about 8'' long. idealy the barrel would be about 3 or 4 inches longer (just an educated guess, i didnt accually do the math). the ignition is a lantern sparker.

its accually pretty fun to mess around with. the fuel is mapp gas or propane, ive been using mapp gas.

suggestions/comments welcome.

note- im fully aware of the fact that i used DWV ABS. due to the size of the cannon, i really dont care, so please dont point it out.

Thats a really cool setup, nice and clean looking. Some handles would give it a tommy gun look. Maybe a handle below the tee and one attached to the barrel somehow would really set it off. Give it a flat black paint job and you have yourself a street sweeper!

Would be kind of hard to twist the sparker with both hands on handles now that I think about it..

Overall Very Nice!

Very nice, kind of reminds me of my "Garbage Gun"

Mine is a lot smaller by the look of it- you should get some decent power out of it.

Do you know how much fuel you need? Mine needs 2cc of butane.
Nice

Do you know how much fuel you need?

umm, i just open up the torch head and spray it in for about 1/2 second or so. i didnt even try to messure the fuel, but i it worked on the first try, so im happy.

thanks for the comments, im accually pretty happy with it. it almost looks like i planned to make it...

originally i was going to use a bbq ignitor and make a handle for it, but i put the sparkers to far apart, so i just made a big hole and put the lantern sparker in.

Forgot to ask but have you destroyed anything with it yet?

If so could we get some damage pics or maybe a video?

Oh yea what do you use as ammo?

the first time i shot it was tonight and i was just shooting some aluminum foil that i rolled up into a ball. i dont know that it really has the power to "destroy" anything. ill have to get some potatos tomarrow. if i feel its powerful enough ill post pictures, but i dont have a camera to post a video.

i dont think i have the mixture perfect yet, but when i do im sure it will have decent power. the foil only went about 150 feet or so, but im sure a potato will go farther.

I have one kind of like that. I shot a jawbreaker and dented the solid brass bell on my treehouse. I bet it has a lot of power.

ive been shooting this quite a bit lately and it is really loud. i used a 3 layers of aluminum foil as a burst disk and it was probably as loud as a shot gun.

it can shoot a marble through a soda can. maybe tomarrow ill get some damage pics up.
