Well, I first decide on the engine I wanted... I decided to go small so I chose a 6" long engine. Well I like to make my rockets about 3 times longer than my engines so thats 18" long. PVC wasn't my ideal body type because of the weight and danger of CATO but it was all I had so for this first rocket it will be ok.
A way to retain the engine served a problem at first. But then I remembered seeing somewher that a hole could be drilled diagonally acrosss the end of the engine and a pin inserted. I used a nail thats grinded down. After inserting the engine, put the pin in and the ngine won't afll out!! But now I need something to retain the other side...
That came to me later... I messed around and decided that if I cut a thin ring of PVC and cut a notch out of it I could squeeze it togethor and glue it in the engine. This worked beautifully!
Fins were simple, I just drew out a pattern and cut them out of a thin peiece of wood. Attaching them was difficult... I just glued them on with Epoxy, anyone got a better idea?
The nose cone was just lathed out of a block of wood by a Rocketry Corespondant... I'll have to ask him before I can publish his name.
A parachut recovery system still serves a problem... I just glued the string inside the rocket.... (not a good idea as I learned in my first test.
