i am new to pneumatics guns and i am thinking of builfding a cheap gun. but any way here i s my theory. i am thinking of having 2 chambers separated by a ball valve. you fill one chamber then the other then you realse the blall valve in the middle to have a lot of air pressure. look at the picture a...

well it turned out that i was not using enough fuel. so i added like 5 seconds now and it is going 100 feet i am pretty pleased with the results since it is a first cannon with such a small c:b ratio. but over the next couple of months or so i will be making another one with a chamber fan and all th...

so i am done sleeving my cannon. i have redisged the sparker position and where the sparker arks and everything all i have to do now is just touch it up cosmetically. but besides that it just dosnt fire very far it will fire about 20 or so feet. i am just a little concerned about the distance of it....

so i just sleved it wiht 4 inch schedule 40 and it fits perfectly. i am going to but a bolt or something on the hole then epoxy it. then i am going to put 2 drywall screws next to the pvc clenout valve. so it will go thourgh 3 layers of pvc.

alright so i should bury it and never let it see the light again

oh and also this is kinda my idea for a new cannon

i want to sleve it to be on the safe side. thank you for your help every body

i was just a little worried couse i heard it will killl you with fragments.

it finally works i used a cheap generic body spray for a dollar. it works really nice. thank for all your help and also i know that my ignnitor is un safe but it holds in really well.

well my cannon will fire betaine a a lighter but wont fire any thing else icave tried aqua net and raid .is there any other aerosol out there i can use with a really good rate of succsess.

i would like to know what youi think the best fuel is for a basic cannon.

i am just a little worried about the chamber it is mad0e of Cresline coextruded cellular pvc but the dude at ace said it would be strong enough. so i would just like you guys opinions about it. also thankyou very much about the fuel.
