everything’s better with fireballs, part II
Tuesday, 27 October 2009
Three days left till Crushtoberfest, and I prepared a total of ten fireball launchers for the Hi-Striker. They’re used in pairs, so that gives us five “wins” worth of awesomeness. Here they are:
First I cut the copper tubes to length, drilled each end cap and JB-Welded 1/4″ phono plugs into each one. Then I soldered model rocket ignitors to the phono plugs’ contacts inside the caps. The gray boxes are aluminum project boxes with phono jacks installed in one side. These will be mounted to the back of the Selleck head, but for now they were a good way to hold each cap as I was soldering. I then assembled the tubes to the caps and used a little electrical tape to hold them together.
I cut each 8″ x 9″ sheet of flash paper into strips (across the short length),
folded all the strips in half together and twisted them loosely,
then stuffed the whole thing into the end of the tube.
