Introduction: Casing Cannon
!WARNING: I AM NOT RESPONSIBLE FOR YOU BEING DUMB. BE SAFE AND EXERCISE CAUTION
I will not show you how to make the stand for the cannon because I don't think most of you have a pair of skis lying around. I also dont believe you have a trumpet you can take the keys off of. I WILL encourage you to make your own stand. I Just happend to live near a junk yard full of this stuff.
Step 1: Finding a Bullet Casing (or Two)
First of all you will need a bullet casing. I used a .303 but that was because I had lots of them. I suggest EXTREMeLY that you shoot the bullet (at a rifle range) to get the casing. In fact I could not advise it more. My great uncle (my father's uncle) once tried to get a bullet out of its casing by smashing it with a hammer, in doing this he succeeded but also shot himself in the leg...
I say find a bullet casing or two because you might mess up and need to try again.
Step 2: Getting the Gun Powder
There are many ways of getting gunpowder. You can make it (there are instructables on that), you can buy it, and you can take it out of a shotgun shell (thats what I did). If you decide to take it out of a shotgun shell, which is what I would expect most of you to do because I am pretty sure many of you who have a gun also have a shotgun, and therefore you probably have shotgun shells.
Step 3: Other Things You Will Need
Of course you need a bullet casing and gunpowder, but there are other things you will need...
~ A drill
~ A 1/8 inch metal drill bit (or around that size)
~ A Toothpick
~ "strike anywhere matches"
~ Saftey glasses
~ Fuse (optional)
Step 4: Drilling a Hole
For this step all you need to do is drill a hole. But this is a little more complicated the it might seem.
First of all you will want the hole as close to the back of the case as possible but if too close you will drill into the primer cap. The metal is thick here and it will take a long time to get through. And if you do get through bash out the primer cap. Then you will want drill through the metal where the cap was making it posible for the gunpowder to light. After you have done this carefully bash the cap back in.
The second picture is where i did it wrong and had to fix it 'cause it was to close to the back. The first picture, however, is perfect, the hole is right before the cap
Step 5: The Final Stand
You are probably going to want a stand. Although it is not entirely necessary that you have one, it does add effect and can change the performance of the cannon. A stand that holds the cannon at the ideal angle will be hard to find. A stand that holds the cannon on its side might not be easy to light. A stand the holds the cannon pointing straight up lets gunpowder pour out. And a stand that holds the cannon diagonal is hard to find. And as I said, you don't need a stand, just placing the cannon upright is good enough.
Step 6: The Toothpick
After you fire your cannon there will be gunpowder cloging up the lighting hole, simply scrape it away with the toothpick
Step 7: Adding Gunpowder and Lighting
Before you light the cannnon you should get a small peice of cotton ball and use you match like a ram-rod. this will make a little blast and make it more realistic.
To light it is not excactly easy. I have not yet found a way to light one nicely. Actualy we needed to add powder around the hole so we could get the stuff burning. That is why a fuse would be nice, but is difficult to find a good fuse.
OH Ya this has not been tested with ammo in it, it could be dangerous!
here are my shots
We have a be nice policy.
