The method below is better described as a medical glove instead of a rubber glove - similar to the link from Mike Riss at http://www.wimpyrockets.com/page16.html

Our SLI team used a cut off rubber (medical) glove finger to hold the black powder,twisted around the e-match wire and wrapped well and sealed wtih masking tape. That worked well across 15 launches in a 2.6" and 4" Mad Cow Black Brant to 5,000 ft and a 3" and 5" scratch built to 3,000 ft.

My avionics experience is also with the Public Missiles designthat includes their own BP holders. I am planning now to build a Madcow Rocketry fiberglass kit and need some advice on the deployment. I have both a Missile Works and Perfectflite computer than I can use but am not sure of a design for holding and igniting the BP. I've seen online the Blastcap http://www.blastcaprocketry.com/index.html and Pratt Hobbies ejection canisters http://www.pratthobbies.com/ejection_canisters.htm Any advice about these or other systems would be appreciated . Hope you all had some successful launches at Roc Stock.
