Step 3Preparing the cannon
This is the hardest step, because it has the most opportunities to screw up, and you wont even know you made a mistake until you do the countdown and it dosent fire. I use a lot of tape in this step, not only to hold the parts down, but to make sure that a bridge between two of the wires cant occur.
Steps:
1. Take a plastic drinking straw and cut off about 3 inches. Put a piece of the homemade fuse into the longer section of the straw.
2. Insert the straw through the hole on the side of the cannon, pushing it down far enough so it will reach into the end cap, however making sure there is still at least an inch on the side.
2a. Take the gallon sized plastic bag and something thinner then the pipe, like a broom handle, and put the bag on the end of the handle making sure not to puncture the bag. Then push the broom handle into the end of the cannon (not the side with the end cap), stopping when there is only a few inches of the bag left on the outside of the pipe. Fold over the remaining parts of the bag around the rim of the cannon and use the duct tape to hold them down to the sides. The bag will be used to hold the flammable liquid that you will be shooting, so it cant have any holes in it, or else it will drip onto the gunpowder.
3. Take the end cap, fill it with gunpowder, and level it off.
4. Screw the end cap on, while holding the pipe vertical. As you screw it on make sure fuse inside remains in contact with the gunpowder. (From this point on try to keep the pipe verticle as much as possible, to avoid spilling the gunpowder)
(WARNING: FROM THIS POINT ON THE CANNON IS LIVE AND FOR NO REASON SHOULD YOU OR ANY PART OF YOUR BODY EVER CROSS IN FRONT OF THE BARREL)
5. Give one push on the straw and fuse on the outside, to make sure it is as far down as it will go, and then secure the straw to the side of the pipe with a piece of electrical tape.
6. This step is hard to describe so check the picture, it should make sense of things. The diagram shows the view as if you were looking in the hole in the top of the straw. Using the scissors cut down about a centimeter on opposite ends of the straw. Split the 2 strands of the fuse down to where the the cuts on the cuts on the straw end. Put a piece of nichrome wire between the two strands and pull it down, once you reach the straw pull the ends of the nichrome wire through the two cuts you made on the straw.
7. Put a piece of electrical tape over the straw, covering the straw, nichrome wire, and end of the fuse. Make sure the contacts for the nichrome wire are still visible.
8. (Warning: do not have the power supply connected to the ignitor when you do this) Attatch the alligator clips from the electrical detonator to the pieces of nichrome wire. The wires off the alligator clips should run UP the side of the tube.
9. Make sure the alligator clips, or wires arent touching and wrap a piece of duct tape over everything and around the tube. To ensure the clips dont shift I press down the duct tape between them, holding them in place.

While this cool it is also illegal. Be careful where you do this stuff the ATF dosen't have a sense of humor about it. There are also local laws that could cause you a world of problems. I've read your other posts here and all are quite good, well researched, and well documented. If, however, the alphabet soup guys start showing up because your neighbor complained they would say that you have a bomb making factory. In this day and age they will..not maybe...charge you federally. That is bad, trust me.
