Yeah wtf about starting fluid, that stuff is great. I use it all the time. DON'T DRILL A HOLE IN YOUR ENDCAP!!!! Get a chamber fan to vent the chamber between each shot and to mix the aerosol and air in the chamber. You most likley have way too much fuel in the chamber, but a chamber fan will preven...

that foam is soooo sticky it won't come off your hands, so don't get it anywhere that you don't mind having foam on.

There are no pictures anyone would be willing to give. It would take a real craftsman to build one with access to a lathe. Joels workmanship is amazing and its machined with great precision. Most people will spend more money making it then spending the 100 dollars

its a piezo from a walmart brand long nose grill ignitor.

I would recomend making one that works off a compressor to test, most people enjoy clouds becuase of their simplicity to make and operate. Vortex's have a different look not as "clean" and inline, they are usually based around a t fitting. The Vortex's will work very nicly if machined well out of a ...

What about ether or metered propane...

Do you know how to solder? It's probably pretty wise to do so, becuase it will make it alot stronger. Its not too hard. i would practice a wee bit before doing it on a cannon.
Its not that expensive (i don't know about france) to start up all you need is some solder a propane torch and some flux

Not if it has a wee chamber

I bike pump works great, You can get a mini bike pump and mount it onboard so you have a self suffeciant pnuematic.

IF you have it in the endcap you can't have it vent the chamber. It also wouldn't really circulate the air well.

Theres always www.spudtech.com to get most of it.

WOw, cool gun. Kill those steel cans and plywood...
Seems like a real fun cannon. Cool damage shots

The gas needs to be moving pretty fast to suck air in. I've made big propane torches with a burner tube of 3/4" pipe, and to get it to actually suck air from the back requires the air to be moving pretty well. Look up venturi. I think that a mini vac would work but you would need to have it on a tim...

same concept as a propane torch there is a venuri that sucks air in from the holes, but you would still need a way to vent the spent fuels. I don't think that the butane will be forced through a large hole fast enough to suck enough air in. You can fill your mini off a propane torch just have the li...

sometimes its not, its kinda sticky on the outside. And it would make it so that it wouldn't stick so the pressure wouldn't just shoot though it instead of pushing it.
