How to Remove Piston from Cylinder

I used to just glue balsa fins and nose right onto the rocket engine.
I also made a hand held launcher for non-vertical deployment
I Wish I had of thought of using the engine to light firecrackers a
cherry bomb would make a great finish to a flight.

Back when I was a kid, model rocket engines were hard to come by, now
they can be mail ordered. It's the firecrackers that are hard to come
by these days or at least in socialist Oregon.

Hello Walter,

Thank you for that link. I wasn't aware that it is on the web. My friend
didn't have the parts manual. He does have the 6 cylinder model, so that
information should be very useful to us.

Also, it looks like your posting did appear in the newsgroup. I think
some newsgroup servers don't update very quickly.

It looks like the messages on the newsgroup have migrated to a
discussion about explosives now :-)

You say that like it's a bad thing. Explosives can come in handy.
Example your starter dies, hand propping isn't working and you want to
crank the engine, just remove a spark plug, put a handful of black
powder in the cylinder, insert fuse and rag to act as a plug, light fuse
and hop in. Explosives can also be used for emergency tire inflation.

Why can't you put in cylinder and use plug to light off????

I'm assuming the think won't turn over in the first place. If it can
be turned enough to obtain a spark one can add saltpeter, sulfur,
aluminum powder and confectioner's sugar in the proper proportions if
one is out of black powder. Not that I know anything about the
particulars, you understand.

As a teenager I used potasum clorate and sulpher.

Poured a spot on cement and kicked with heel plate and went off.

Also put in a CO2 cartridge and set off with home made fuse. Made a
powerful rocket (half a city block).

How I ever survived growing up I don't know looking back.

Big John

Looking back I can see several occasions where I should have been
injured or killed with some things I did. I proved launching a plastic
model Saturn V is possible with off the shelf C engines. I also proved
that didn't include going in the intended direction.

There was also the day the WAC Corporal got it's engine inserted
_backwards_. Hit the igniter, and "fffttt!!" the spurt from the
ejection charge _was_ enough to lift it off the launcher, and it
coasted straight up to about 15-20 ft in the air on the delay.

*Then* the main part of the engine lit off. Stopped dead in the
air and simply _shriveled_ into this oblong charcoal ash, that sort
of fell/drifted back to the ground.

After one got through the crying over the destruction, the memory was
good for some (bittersweet) laughs.
