I’ve heard some rumours about people with similar pipes making model rocket bazookas. Of course, I’d think someone doing that sort of thing would probably want to wear a motorcycle helmet with a full face shield and thick leather gloves, but of course, I’d have no way of knowing for sure.
For the ultimate fashion statement, I'd throw in a chrome leather apron.
I heard somewhere that these kids pulverized the solid rocket engines from the weaker ones (A's, B's) filled a spent CO2 cartridge with the powder, put a small piece of primer cord in it then sealed it epoxy.
They placed the cartridge in the nosecone of an Estese Alpha 3 rocket, with end of the primer going into a hole into the "parachute load" in the top of the Alpha's engine.
adjustments (to fin placement) must've been made to balance with the increased weight.
The Alpha's stabilizers were modified to fit into a length of pvc or the tube from roofing paper. A .5 V dry cell, solar igniters, breech plate and grip with a trigger were added in some manner.
Not sure what they would've have done with that thing but going on a "Goodyear Blimp Hunt" prolly wasn't it...
