Rock A Chute Mark I
 

Using (mostly) Original Parts, I was able to build this MARK I, which will go to Seattle Museum of Flight. Cool! Danny

Very nice, Danny!

Thanks,,, Since I've done most everything in rocketry, collecting wise, the Hard Core Stuff , like this, are the items I never got around to. So hopefully in my next chapter in rocketry I can find and learn more about these. ALL help appreciated! Danny.

Didn't the Rock-a-chute engine use cannon fuse?

Darned tootin' they used CANNON FUSE.
Still should be a perfectly legitimate ignition method EVEN AT SANCTIONED EVENTS.

I have yet to see a rocket engine fail to ignite when using cannon fuse.
When I was in the 8th grade back in 1983, my best friend and I showed my 8th grade science teacher this method; he hated the rate at which electric igniters 'fizzled' and failed to ignite motors. When PROPERLY used, I have had a very low igniter failure rate, but for the average 8th grader the fail rate is high and expensive even back then for school programs.
My teacher switched to FUSE for every rocketry class segment until he retired.
We did advise him it was against the mamby-pamby safety code, which he cared about as much as we did...very little.
