Was that the "Fort Sill Beta" design that ran on zinc dust and sulfur?
I still have my copy of "Rocketry for Amateurs" that shows how to built that rocket.
It did use zinc and sulfur. A small amount of black powder was used to set it off. We used the wire element from a car cigarette lighter to set it he black powder off. I was not aware that it was called a Fort Siil Beta. Maybe they were using our design in the book since we and another Okla City club were the first that I am aware of firing at Fort Sill.
I would like more info from you book.
So do I. It's locked away in my safe right now. To show you how times have changed, it was a gift from my school guidance counselor when I was in junior high.
I had learned a lot through trial and error and was up to the KNO3/C6H12O6 and aluminum bodies level when I received the book.
