Mini cannon.

I found this one 20+ years ago. Thinking it was a signal canon off some kinda ship and someone put the carriage under it back in the 40's?


 
I had one of those Calcium Carbide Cannons when I was a kid. I should go dig through my parents house for it. Haven't seen the thing for 35 years. They are phukin louddd!!!!!!!!!!!!
 
I remember my dads cousin had a whole collection of brass cannons in poland,. I shoul'd ask him about it. Apparently some used to fire with match heads. I will look into it.
 
Here's one I made:

And I can't forget a video...

Here's one from my iPhone.. Shows some "Aftermath"
 
No worries...mine arrived today. Now, if only I could find some fuse material...

1) Go to gun shop
2) Buy some FFFFG black powder (or other grade as long as it's black powder)
3) Disolve black powder in water to a wet paste consistancy
4) Cut up some 2" X 1" strips of thin tissue from a shoe box
5) Soak tissue in black powder/water slurry
6) Twist wet black tissue into tight thin strings
7) Dry them on some old rags

= Fuse

Test a few to confirm consistant burn rate. If it's too fast, twist them tighter when wet. If it burns too slow, untwist just a bit. Only make as much of the mud as you need as it will go bad if left out too long. You will see the KNO3 crystalize and rise to the top.
 
Thanks, AWOL. The timing is funny...right after I posted, I started to think about whether black powder was water soluble, since I knew the fouling was. I mixed up some of the slurry, then soaked some sewing thread in it and spread it out on a paper towel in the kitchen. My wife casually asked what I was up to...when I answered that I was experimenting with making cannon fuses, I though she was going to have a stroke. When she saw the actual cannon, she started laughing, and hasn't stopped yet.

Then I found your helpful post above. I now have some tissue fuses drying as well. I have only FFg powder on hand, but I'm going to give it a try tomorrow. With any luck...BOOM!!! :)
