Just something to try on those boring days when you can't go out and shoot...

Haha.. cool stuff..
how would you aim one of those?
maybe a bent pipe should be placed on the blowing hole, and ensure that a strainer such as mosquito netting is used so you do not inhale the pellets.
Maybe even a rubber balloon for per charged propellant...

Gee mate...if you are gonna go to that much trouble, why not build a mini mortar. Get a 4 foot length of 3 inch diameter poly pipe and fit a smaller piece to one end (combustion chamber). Seal up the small end with a poly cap, fit a small capped nozzle to the cap on the end, fit a piezoelectric bbq (or similar) lighter through the side of the poly pipe just up from the cap.
Now the fun begins...push an orange or tennis ball or something (SOFT) that is a not an overly tight fit down the main tube. Open the small nozzle on the end and spray in a small quantity of Aerostart or similar...you can adjust the quantity after each "shot" till you find the best amount. Reseal the small nozzle, aim and press the piezoelectric igniter. WHOOMP...the aforementioned orange or tennis ball is on its way. In effect, this is a small mortar. A damn lot of fun if used sensibly.
One of the bikie gangs here in Australia actually built a small "howitzer" on wheels using heavy duty water pipe about the diameter of a coke can. Coke cans filled with concrete were the projectiles. Not sure what they used as a propellant though. Suffice to say there is no way I would want to be within a thousand yards of that thing when being fired. Most bikie clubs only have maybe a dozen brain cells to share between them all.
Cheers, Vince

You are going to get me in trouble, Vince, if you keep posting ideas like this in the "cabin fever" months of winter up here in the frozen north.
I'm kind of glad that I left the cannon my friends and I made back in the wide open spaces of central Vermont. We used to lob #10 cans filled with flour using that one. I guess anything that goes boom is a lot of fun.
Cheers & beers

Better figure out what your going to do. Looks like you have another storm ready to dump on you! You could change your hair color instead.

You're a big boy Marty...you can handle the heat mate.
Good thing about the "poly pipe mortar" is that it doesn't make a lot of noise and it is difficult to aim it directly at something...that is where you can have a lot of fun with an orange...they tend to splatter on impact.
Cheers, Vince

The first tennis ball "mortar that I built used a tennis bal for a projectile and the heads off paper matches for propellant. Unfortunately the pipe I used was made of lead... I learned how NOT to make a hand grenade! The ball did launch but there was a lot of lead pieces all over.
At least I had the presence of mind to be under cover when it went off.
since then I have successfully made better mortars - shoulder mounted rocket launchers, and even an infrared guided rocket. I don't have any of them any more but it was fun doing it when I was younger - yoday you would be arrested for building stuff like that.

you must fit in the "older than dirt" category if you used pipes with lead in them!

That orange hair was for a few weeks in 2005. It's mostly gray now.
Still have to find an avatar builder to reduce files to allowable size so that I can change it.
