Thought I had it all figured out. Bought the wire, bought the black powder and acetone. Bought the ping pong balls. I made a batch of ignitors per the formula I found on this web ring (www.sparksrocketry.com/ignitors.htm) only to be told by one of the old hands that a black powder based ignitor was only good for igniting a black powder motor. He said the ignitors used on Aerotech reloads and the like need a pyrogen in order to ignite the composite motors. I haven't had the courage to try to light one of those expensive reloads since I was told that. He said that APCP lights due to pressure rather than the flame that my ignitors yield. I'd really like to pursue this since I found it rather enjoyable making the ignitors, but I don't know where to go next with this. Thanks for the help.
