Dipped igniters
Today I finally had all of the elements come together. I dipped the Estes starters in the acetone/ping pong ball mixture, then in the black powder that I finally found at Wal Mart yesterday. I'd hoped to sneak up to B6-4 Field to try them out, but as I type this it has started raining. There's always tomorrow.

You can always test-fire a couple in the garage or even a fireplace.

I've been using Chris Michielssen's method with great success. Fabri-tac and 4F BP.

I have been dipping Estes starters in the acetone/ping pong ball mixture, too. Recently I have added some Quickdip mix to the goo and it has worked well. DARS does a lot of outreaches with scouts and other groups. Always have some of these igni...starters on hand. Went though almost 20 at one launch. I dip them far enough in the mix to coat the two parallel sections of the "item" to help insulate them.

I just use dope and black powder. Seems to work OK.

As long as it is NITRATE (Nitrocellulose) dope. Regular Butyrate Dope when dry is actually a retarder to combustion, not an enhancer.
