well i have had some experience with spud cannons in the past 7 years.. about 5 years ago i built a very large abs cannon that i still have not fired for fear i will blow my head off.. well not really its just the fact that i live in a city and just haven't had the time to go out to fire it or finish it. the original plan when i built it was to eventually hook a propane system to it.. (keep in mind at that time spudtech had just started doing the propane system and i copied his exact design, minus the propane system). anyway.. today i got bored and decided to look and see how the spud online community has grown.. and wow.. so much has changed.. fans, constant sparks, hybrid guns.. anyway i decided i wanted to build a new gun.. or convert my other one that i was describing above into a propane powered cannon.. anyway.. i have been researching and haven't learned too much due to lack of plans on the net.. i am seeing that alot of people are using the 80mm fans to mix the propane because of something to do with oxygen?.. i am very confused about the matter. but basically i want to make a cannon or convert my cannon to use propane, be able to refire in less than a minute, and be as loud/quiet as a classic combustion gun.. now as far as loudness goes.. i'll take what i can get, quiter is better (i live in california) but if its a problem, then no worries..
i just need to find a website with some real plans that are thurough to build what i want or i need to find someone that knows what they are doing that could explain some things to me..
anyway, i thank you guys for reading this so much and i hope to hear from ya soon!
ps. my current 5 year old unused cannon i was talking about was based off the size of the 3 cannons pictured here:
