Help with a combustion mortar please
Posted: Thu Oct 06, 2016 2:05 pm
hey all.
im in a pickle i have a big airsoft game next sat. and thought hey ill build a potato gun mortar. I believe i underestimated these boom tubes. Because i cant for the life of me get it to fire. Here is the design for a combustion chamber i have 1 foot 6 inchs of 2in pvc run into a ruducer that runs into 3 feet of 1-1/2in pvc. ive tried axe, spray paints and carb cleaner and all light up like a flame thrower when sprayed in to a flame. for spark i have the sparker out of a bbq lighter. I originally had it very close to the end cap so that if i needed to i could easily work on the leads. after not being able to get it to fire (it sparks but i cant fire the gun) i thought maybe its too close to the end and fuel isnt getiting to it so i moved it more towards the middle. still i get spark but no igntion. I have tried all fuels at 1/2, 1, 2, 3 ,4 ,& 5 secs of fuel with no luck. if i introduce a flame it the fuel lights but i cant get it to light via spark in the sealed chamber
I would really be thankful for yalls help here i'm stumped
