I've heard of people doing similar things. When employing a PVC pipe, the hardest thing is keeping the rocket centered. I've found, er, heard that one way of dealing with it is to put a base plate on the tube with a slightly off-center guide rod that runs the length of the tube, and can be used with the standard launch lug on most rockets. Another technique is to spin-stabilize the rocket with fins that are at least half the length of the rocket and the diameter of the inside of your tube.

Lots of crazy people out there with too much free time to come up with some of this stuff...

A FRiend of mine and a fellow supervisor at a major Utility in the Boston Area, before I retired, made one out of PVC that did nearly the length of the Reserve Channel.

My lunatics not to be undone with some technical direction from me and some help from out Boiler makers , made one from P-22, CRMO. We fabricated an accumulator with a high pressure quick release solenoid valve.

The tube was 3" and we pumped up the accumulator to 3600 PSI from the starting air compressor on our Gas Turbine. I think we might have put one out as far as Deer Island.

funny, I've heard of both of those solutions myself...

ya' know what else I heard about - piezoelectric igniters and trying to fit them into the nosecone with the CO2 cartridge for um, "impact".

and shotgun shell + hole in side where the powder is + primer cord = grenade
