I've got a steel 72 that failed hydro, it did not go back to size after the pressure was released. I'm thinking of making a small black powder noise maker for my front yard. No projectiles just some BP and a wad make go BOOM! Anybody ever do this?
 
Sounds like a lot of BP to get a bang. Look at the dimensions of the tank, better served by a smaller diameter vessel for your application I would think. Even better, make a lamp and buy a BP cannon.

I'd love to buy a BP cannon where does one go to buy a BP cannon big enough for the front yard?:coffee: My second choice would be a bell. Lamps are well ..to ordinary for me.:wink: A lot of BP would make a big boom! I thought start with a 1/4 cup packed with a ball of newpaper and work up from there.

Guys, guys... a black powder cannon? Really?

Didn't you learn anything from this thread??

Make a carbide cannon out of it, it's a lot safer than loading it with BP.


The valve hole would make a great location for the sparker

Yeah you have to be a member of The Pub to access it... don't worry, I was just making a silly joke :wink:
 
Remind me to put on my flack vest when you light this thing. It failed hydro because something is wrong with it, and you want to load it with explosives?

On a practicality note, this cannon would be classified as a 50-pounder. That's a BIG cannon. You'd need a serious wad to make it go BOOM instead of PFFFFF.

I would think you'd be better off with one of those Spare Air tanks. It would be easier to get a bang, and if it exploded the shrapnel wouldn't penetrate the neighbor's houses.

Then maybe graduate to a D-size oxygen tank.

You make it sound so dangerous. A 50 pounder WOW! That's like 105 Howister! :rofl3: I think Hartford is far enough from RI you'll be OK.:wink: I'll point it west let me know if you hear it. I don't have neighbors that close but, I'll go down to the river anyway and use a long fuse so I can get the heck out of the way!:shocked2: Maybe I'll setup a video camera to record the disaster.....I mean event! No balls no glory! Man your ramrod!
