Boys, she was running real strong just bef= ore=20 those pistons turned up in the oil pan.


Best power mixture.


I did not understand the power of an explo= sion=20 until the day we were setting off our Carbide rockets in front of Billy Oa= kley's=20 house on Waverly street. A Carbide rocket is a big juice can

with about 2=E2=80=9D of water in it. Inve= rted into the=20 first can is a second can that is just a bit taller than the first so that= about=20 1/2=E2=80=9D inch of the can sticks up out of the first can. This second= can needs a=20 touch hole

just even with its rolled lip, so the touc= h hole=20 is available above the edge of the bottom can. The touch hole is made with= just=20 the right sized nail and a hammer. All this very scientific stuff for 10= year=20 old's.


You drop a few crystals of carbide (for ca= rbide=20 miners lamps) into the bottom can with the water.The carbide water combina= tion=20 produces acetylene gas. You place the Rocket can into the launch can.You= wait=20 just the right length of time, and this is the key to success, it is a tim= e vice=20 gas production rate problem. Or too rich or too lean problem.

Looking for best power.


Too long before you light the mixture at= the touch=20 hole with a safety match, and you get a miners lamp.Just a plume of acetyl= ene=20 burning. The gas has displaced too much of the available oxygenand only bu= rns=20 outside of the can where there is adequate oxygen available. Too Rich.

Or.

Not long enough, and there is too little= gas to=20 sustain a burn and the touch hole pops and blows out the match, or you get= the=20 inner (rocket) can to hop out with just a fluffy sounding whump. Too Lean.=


But if you become an advanced Merlin at NA= SA style=20 rocketry, and wait just the correct length of time, then the mixture= is=20 just right, the rocket (inner can) leaves with an impressive (to 10 year= old's)=20 Kaboom and a cloud of water spray.  Ideal best power mixture.


There may be competition among your follow= ers to=20 catch the rocket can when it returns from its mission, but a savvy Merlin= just=20 observes lest the rocket can land on a parked car or in somebody=E2=80=99s= flower bed.=20 One must be ready to recover the launch can and retreat on ones bicycle in= a=20 direction opposite the actual direction to ones home. No need to complicat= e the=20 situation with lengthy conversations between the aggrieved home owners and= your=20 parents.

I am forever grateful to Billy Oakley's da= d, Frank=20 Oakley who apparently was some kind of genius, and for showing us how to= do this=20 kind of stuff.

Why yes I was an Ordnance man in the Navy.= How did=20 you know?
