i know there have been posts before but can someone show me how to make a not real expensive, but yet still good flamethrower??

~sigh~
Look at the other posts on flamethrowers and look at the one that i suggested and that is the cheapest flamethrower you can make (unless you go with a cheap disposable supersoaker flamethrower).

no im not looking for a bitch flamethrower im talking about a flamethrower that has a long range and lots of fire

get a pesticide sprayer and make some mods... just a thought.. I havent tried it.

metal fire extinguisher + liquid fuel + pressurise with CO2.

can someone give me a step by step on how to do this because i have no clue on how to do this

If you can't figure it out yourself then you're too dumb to use one responsibly.

how the fuck do you use a flamethrower responsibly? use it to light a match?

If you use it responsibly, you will use it in a manner that will not pose a danger to yourself or anyone around you and will not damage anyone's property (including state/government owned property).

Well wheres the fun in that???
