me and a buddy where talking and would it be possible to build a polish cannon out of 55 gallon drums and shoot a exersice ball out of it or would the 55 gallon drums be way too thin

Stop being a dorkweasel and get your head out of your bum.

Think son, think. If your not capable of conceiving the relative forces for that cannon, then you 'ought not be buildin' her.

thats what i was saying i was putting it here pretty much to make a point to my buddy i hope this will keep him from blowing himself up

Wow, still a fail... Dude, I recommend starting off with something small like a regular 'ol spray and pray. 1 foot x 3" chamber and a 3 foot by 2" barrel.

Whenever I read "polish cannon" I cannot but think of this unfortunate AC-119 Stinger nose art...

I say go for it. I see nothing at all wrong with using a steel barrel to launch excercise balls.

I have (unfortunately) seen sealed steel drums rupture violently due only to volatile solvents inside expanding as a result of solar heat, bowing out and tearing at the seams. They're tough, but internal surfaces are large and there's a lot of force imposed on them even with low pressure.

Not saying this won't work, but caution should be exercised

Yeah thats a good point. Remote detonation highly suggested. No hand helds

That would certainly be amusing, to distant onlookers at least

You could wrap the tanks in fiberglass. and it would be amusing to see someone hand hold the cannon.

Screw it, go shoulder mounted and make if 3 barrels long.

ya cuz everyonr can carry those lol no im pretty sure that you might get a shot out of it but i think it is extremely dangerous. today my buddy said if ill help him make it he will supply the barrels and shoot it but i dont think he will be able to get 2 more barrels but if he does ill try to take pictures and post them because that would be really cool looking

If you do make one, video would be awesome.
