I recently spent about $100 on making a simple combustion cannon(10 in. chamber...36 in. barrel)...but it wont work!..I think it has something to do with the ignition...I tried BBQ and camera flash ignition.both BBQ and camera ignitions always make a spark when i test the cannon without fuel inside..but i dont think it makes a spark when there is fuel in the chamber, Then i thought it had to do with the air/fuel mix, so i installed a fan.....guess what?!..it still doesnt work. I spray about 3 seconds of right guard into the chamber, turn the fan on for 3 seconds...charge the camera.....and ignite....but nothing happens...ive been trying to make my spudgun work for about a month...and im about to give up.... ......or make a pneumatic cannon..... .......I would EXTREMELY appriciate it if someone could help me out.
It sounds to me like your fuel is not combustable like PCGUY mentioned. Without being able to see the gun and try to ignite it, that is all I can think of other than the possibility of the fuel/air mix. Best of luck man, and don't give up.
I guess I'll go out to CVS and buy some new fuel, thanks guys.
guess what, i found the best spud gun fuel, it contains propane, hexane, butane,and acetone....the only problem is that is is spray adhesive
dont you think if i spray a lil in my chamber, ignite, and then wipe it all off itll b ok?
you can modify your posts, they hate it when people double post. and just becuase it has alot of flammable fuels, doesnt mean that the quantity of them add up to as much as just one or two in another fuel
i followed the how to on this sight but the valve is letting air through it.
anything i can do to dertimine why?
btw its the same valve as in the...
