I know i haven't been on the forum lately, but i am half way through my copper piston cannon, and i have just finished my first combustion. It is a spray and pray and i wanted to know what the best kind of fuel is, Keeping price in mind. I am also finally getting to posting all of my other launchers that i havnt posted. (finaly)

wd-40. I sometimes works for me, I use a combination of wd-40 and hairspray and it seems to work better than anything.

Hairspray will eventually gum up in your chamber. Carb cleaner is a favorite among dedicated spray and prayers...

A $0.99 disposable butane lighter. (linky)

For my spray-n-pray I used some kind of anti-static spray, don't remember what it was called. No gunk, worked great. Well, great considering it was a spray-n-pray anyway.

Go to Publix, kroger, wal-mart, etc. and look for some sort of generic right guard (it usually says something like "compare to right guard.") it usually contains propane, butane, and alchohol, and you don't need a lot, which is a plus.

The old can of brown rightguard used to be the best!

It contained SD Alcohol #40-B, Propane , Butane , Propylene Glycol, Fragrance, Isobutane , Triclosan. All of which being very flammable! The aerosol spray that came out was also very fine which allows for a better air-to-fuel mix. But getting it perfect with a spray-n-pray is near impossible.

Also, back to what Paaiyan was referring to is called Static Guard. This stuff is as good or better than right guard. It is very clean burning, leaves no smell or buildup.

I hope that helps Dudeman508! G'luck 8)

This stuff. Its main ingredients are propane and butane. It is by far the most powerful spay I have used. And it leaves only a baby powder smell in the chamber, no gunk.

It is found at walmart in the beauty section... or go to any other beauty supply store and find any kind of nail dryer.

Get a can of BUTANE. You know, the ones used for camping or refilling lighters. After that get a BIG ASS SYRINGE. Metered fuel!!

Let me sum up what everyone has said (save CasinoV); Go to Wal-Mart, look for any aerosol you see, grab it and look @ the ingredients and find the one with the most propane, butane and alchohol, and the least amount of other stuff.

I agree with CasinoVanart, a syringe and some butane or propane is the way to go.

A disposable butane or propane can with a spray paint nozzle attached.
I had a photo, oh well, just a spray paint can nozzle on a disposable butane can.

I tryed using some anti static spray, that i know for a fact is very flamamble, my chambre is about a foot and a half of 1in pipe and i spent about 10 minutes today trying to get the fule mix right .Is it that exact or am i doing somthing wron

The Perfect Fuel Source

Yes Yes, STHORNE.

But he said spray and pray and keep price in mind; therefore, running a metered propane system is out of question. He's better off just using aerosol cans that contain SD Alcohol #40-B, Propane , Butane , Propylene Glycol, and Isobutane. If it has all of these then you got a good propellant.

*NOTE* Don't use anything with a fragrance. This is because in fragranced products you will find a smaller proportion of explosive ingredients.
