a quick way to make a professional looking lead wire to attach to a glow plug. replaces the butt splice on Kipkay's design, or your rc car's damaged lead wire.
for those making the fireball shooter, keep reading at the end for a little bit of inside glow plug information.
Step 1: First things first
first of all, thank you very much to MAKE magazine (http://www.makezine.com/) and Kipkay (http://www.instructables.com/member/Kipkay/) for the original versions of the flame shooter instructable.
i am not redoing Kipkay's instructable, but merely taking the open-source horse by the reigns and going to town. i've got a quick upgrade and some information that might help with glow plugs. hope you enjoy.
now go get this stuff:
some stiff bus wire (around 22g)
some hookup wire (whatever gauge you want)
a small bolt slightly smaller than your glow plug's lead
heat shrink tubing
Step 2: Wind your coil
pull about two inches of the bus wire out without cutting it off. begin winding it tightly around the bolt as shown in the pictures. once it is approximately 1/8" to 3/16" you can remove the bolt. if you've done this correctly, it will be too tight to simply pull it off. grab a screwdriver or whatever is applicable and unscrew it. this is a good thing. if your coil doesn't hold tightly, you need stiffer wire.
if you are making a lead wire for your rc car, continue the coil until you have about a 3/4" coil.
Step 3: Cut the cord
take a nice sharp pair of snips and cut off the umbilical cord to the mother coil. do it at a nice angle toward the coil so as to leave no sharp corners and cut in a spot that is contiguous with the coil. we don't want anything sticking out.
for an rc car lead wire, just snip the coil at both ends in the same fashion. make sure you remove the screw before you snip the wires. skip step 4
