Help with first combustion

[Marffy]

i was thinking of making a combustion but i need some input on what to use.

I was thinking:
ABS chamber and barrel
PVC or wood stock
4inch chamber
Fan
camera sparker
mapp, propane, or hairspray for fuel
over-n-under design
6 screws to create 3 sparks


give me a list on what to use

sounds like you've already got a good list started .except try to get sch.40 parts . and try to stay away from bell reducers ( not sch 40) . there is lots of great builds on spudfiles to get ideas from. hair spray isn't the best fuel to use . but do try to meter your fuel.. starman has a great metering setup & i use it too . cant wait to see your finished cannon

thanks! now i know i got a good plan. i quess it all started when i found a 4inch fan up in my attic. so i had to make somthing out of it. But starting this project will need me to get off my ass and finish my pneumatic cannon. ill also need some money...
