Some basic fuel advice for using aerosol propellants:
Less fuel will often make
your spudgun shoot farther. Always experiment with different amounts of
fuel. It seems strange but when you combust a fuel inside of a closed
container, such as a spud gun chamber, if you have too much fuel you will not
have enough oxygen to ignite the fuel mixture.
Remember less is more!
Propane : Direct propane injection and meter
Right Guard : The choice fuel for aerosol
Chamber Fan: More fuel efficiency
"Ghetto Propane Meter": Cheap, yet
accurate fuel meter
Do not use high powered fuels such as
acetylene, hydrogen or oxygen. If
you do you will die.
nowhere capable of withstanding the extreme power of these fuels, and will
explode with much PVC shrapnel.
A list of fuels commonly used in spudgunning:
||See above link, its good stuff, clean and very
powerful! Note: Supposedly Right Guard has stopped using flammable
propellants. You can still use a generic store brand, just make sure
the propellants are flammable.
|Glade Air Freshener
||Has propane, butane, isobutane as propellants,
powerful, but has a large percentage of water and smelly stuff.
|Starting Fluid (Either)
||Very powerful, but a little difficult to measure
out, usually 1/2 a second will be enough fuel. Hard to get a small
enough amount of fuel.
|Static Guard (for static on clothes)
||This stuff rules, as good, or better than right
guard! It is very clean burning, leaves no smell or buildup.
Again, very powerful! (update, it is now "fresh scent"--not a
bad smell, similar to hairspray smell)
Butane (for refilling lighters)
||A clean reliable fuel, very powerful. The
only drawback is that it is somewhat difficult to get the right amount.
||Cheap, very powerful, EXTREMELY reliable, clean
burning. Able to be precisely metered with a propane meter.
|Oust Air Freshener
||I haven't used it personally, but it is supposed
to be powerful. Again, it has stinky stuff like glade air
fresheners. I would assume performance would be similar.
|Cologne (sd-40 alcohol kind)
||Very stinky chamber, but a good fuel.
||Terrible... it gums up your chamber, don't even mess with it. (Plus
it's weak compared to many other fuels)
| Super-Lube Dri-Film from Lowes
||I've not used it personally, but it's supposed
to be great!
|Some Airbrush Propellants
||I have not used it personally, but it would be
clean burning, as it would be a pure fuel.
||Used to work, but now the propellant is CO2,
forget it, its worthless now, wont even light...
However, if you find an old can (it wont have a blue dot around the
nozzle hole) you are in luck! Its good stuff, but does leave a film
in the cannon.
|Old Spice Deodorant (aerosol)
||Clean and powerful, similar to Right
