Step 2Building the fuser
This project uses the fuser to hold the 2 spools, coat the strings with black powder, and combine them to form a fuse. The steps do not need to be followed exactly, as long as you end up with something that looks like what is in the picture, and its sturdy, it will work.
Steps:
1. Take the scrap wood and cut it so you have a one piece about a foot in length, and another about 7" in length.
2. Hammer the 7 in piece perpendicularly on top of the foot long piece with 3 nails. (Refer to the photos because they will probably help more then my worded instructions)
3. Drill (2) 1/4" holes through the 7" piece of wood a few inches from the center. However, do not drill all the way through the wood, drill 3/4ths of the way down, the dowels will be sturdier this way.
4. Cut the dowel into three segments, 2 of those segments will be the same lenght and should be at least 4 inches long (to hold the cotton spools) The third segment will be inserted in the tupperware container (To hold the cotton string under the gunpowder)
5. Drip some weldit glue (wood glue could be used instead here) into each of the 2 holes and on the bases of the 2 equally lengthed dowel segments, then push each segment into their holes (if you cant push them in all the way try using a rubber mallet to gently hammer them farther in)
6. Use the 1/4" drill bit to drill 2 holes in the tupperware container. These holes should be no more then a two centimeters from the bottom and on exact opposite sides of the container. A method I used was I drilled a hole on one side, then pushed the 3rd segment of dowel into the container. I then marked off the other side where the dowel hit, and then drilled through there. Push the dowel through the second hole and seal off around both holes with the all purpose glue (Both of the holes need to be waterproof)
7. Take this container and line it up on the foot long piece of wood so that the dowel running through it is parallel to the 7 in. piece. Take a magic marker and dot off two holes near the top of the container (this is where the cotton string from each separate spool will enter), and mark one hole on the exact opposite of the container (this is where the fuse will exit).
8. Find a drill bit about the size of a piece of string and use it to drill through the 2 marker dots on the side where the cotton string will enter. Take a drill bit the next size up from the one you just used, and drill one hole on the other side of the container where you marked off. The hole where the fuse will exit is the important one, if it is too big then it will not clean and even off the fuse, and if it is too small it will not be big enough to fit 2 strings through it.
9. Using the weldit glue fix the tupperware container at the end of the 2x4, so the two holes face the side where the cotton spools will go. Wait for it to dry and you are finished.
