Hi im new to this and i was wondering about if a fan would work well for me. i have a simple combustion cannon with an electric BBQ starter fuled by walmart hairspray and was wondering
1) what does a fan help do?
2) should i have one?
3) were can i get one?
4) how much will a small one cost?
Note: the duct tape is only a fassion statment, it is in fact held together with glue!

if there is anything else i should do with it tell me cuz i have no idea, it use to be set off with matches so even the BBQ lighter is a huge step in technology for me. if you have any comments about it (please give negative comments i need the criticism) anything i can do to it short of throwing it out would be most exelent!!!

a fan helps vent the exaust gas after firing, thus makes loading faster, also mixes fuel for u, so it fires more often. a computer store should sell them for a cheap price.

1) Mixes fuel, and exausts combustion results. A more even fuel-air mix gives better combustion, and therefore, more power. Having it to exaust combustion results is mainly conveinence.
2)
if (Preformance_increase >= Pocketbook_drain)
buy_fan();
3) Any decent computer store should have them. Just ask for a "case fan", they will ask what size you want - respond 'No particular size'.
4) It'll probably cost you 10-15$.

A 9v battery there made to run off 12v but 9v works. Just hook the leads from the fan to the battery.

hmm...seems risky. couldn't the current in the fan ignite the fuel?

No, it couldn't. Computer fans are brushless - there are no sparks, unlike a normal (brushed) motor. And people have tried ignighting mixtures with a brushed motor, and failed.

I succesfully ignited right guard using a brushed fan with a higher voltage
and exposed moter it was in a gun for a freind to shoot antennas for a ham radio and it dosent used a igniter.

I got my fan for free. It came out of an old power supply, one for an old P1 system.
There are a few different things you could do besides a single 9volt, which would be kinda slow. You could wire up 6 AAs in series for longer life (or more for more voltage=faster mixing/venting), or 2 9volts with a 15volt voltage regulator. Or even more cool is a fan controller like I built. They have the plans on burntlatke.com if you are interested. If you feel like building the simpler version without relays, send me an email or something and I will draw up the plans for ya. This is probably beyond the ability of a novice though.
Or, maybe I would be willing to make the whole fan controller for you and ship it since I have all the parts and some experience.
