I noticed a delay and an occasional misfire using the newer Estes "Starter" Igniters. My schoolyard launch controller is a typical 6 volt Estes system. Ignition was slower, almost like using bare nichrome wire when I started launching rockets in 1969. Press the launch button and hold it down until ignition of the engine.
I had tried using an available dip kit but became frustrated when the mixture continually dried out. Sure you can add acetone and stir (very messy), I wanted a simpler solution.
I wrote a short article for the NAR Sport Rocketry magazine and was surprised when it was published in the 2017 September/October issue. This post explains what was in that article.

I have not used this technique in engine clustering. I cannot guarantee this method will work with clusters.
I'm fortunate to have a black powder gun supply store here in Orlando.
I bought some Goex FFFF (4F) gun powder. The 4F is finer and faster burning.
The Beacon Fabri-tac glue is used to bond the powder grains to the clear igniter tip.
Shake a small amount of the black powder into the bottle cap.
It doesn't take much. Be careful, the black powder grains can and will go everywhere.
Squeeze a small amount of the Beacon glue onto the clear "Starter" tip. Go light, it doesn't take much glue.
Hi, Chris,
ReplyDeleteCool technique. I notice you've got a little yin and yang going on in the bottle cap in the photo!
Hi Ed!
DeleteThe "Yin-yang" wasn't planned but it works for me! Great to meet and catch up with you at NARAM.
