Haha just put a barrel port on jsr's design and you've got yourself an engine with a built in pneumatic machine gun :lol: Maybe you could build a pneumatic tank!

OMG just get an air cylinder and hook it up to a 3 way valve
(or a double acting cylinder & 5 way valve)


If you're uberambitious then convert a 2 stroke chainsaw engine to LPG or something like that :D

I still say that a hammer valve would be infinitely better. (barring rotary valves of course). :D

That would be sick :D

Poland, a cylinder and a three way would be expensive!

Cheaper than a custom machined compressed air engine. If you're such a cheap skate then get a ready made one from some air powered tool

I'm not custom machining one, I'm using brass tubing from the hardware store that is like 2 dollars a stick.

I've said it for a long time, such a motor with high pressure and a narrow cylinder to prevent pressure loss coupled with a set of rotating barrels driven by the crank and fed by the motor exhaust = self powered pneumatic gatling :D

JSR, how would a narrow cylinder prevent pressure loss? Unless, you have an enlarged area above the cylinder to increase the air used per stroke, a narrower cylinder is going to start with less air than a wider one, and result in the same pressure loss...

I wonder how much deeper the ocean would be without sponges.
Right now I'm having amnesia and deja vu at the same time. I think I've forgotten this before.

Fair point, what we need to reduce pressure loss is a separate reservoir...

not bad but you'd still need a starting motor or some sort of mechanism that does that
