meters
I was told by my friends that 1.5:1 Was a good ratio but I want distance not sound. I just thought the web site I listed earlier was good to use. What would be a good ratio for distance be? If I got people confused that is what I get for listening to my friends in my town, sorry

The way I made my cannon was using metered propane/mapp, The meter pipe is 9" long and a 3/4" ID, I use 35 to 40 PSI in it at 5% of propane or mapp. The chamber is an exact 19 3/4" long at 4" ID the Barrel is 50" long and a 2" ID, all of which is all sch-40/NSF-PW, with an exact 1.50:1 C:B Ratio. A chamber fan and a 650kv stun gun for ignition. I know it is long but like I said I wanted distance. I was going to use duck tape for a burst disk to hold these little nerf balls and small plastic balls, calking tubes work to. like you said that dependent opon the chambers potential energy I thought this setup would work but any ideas can help to make it better

I never thought of making an over/under design. It sound's cool to try being that my cannon is not put together yet, I can still do this. So if I got you right using the over/under design can't I just cut the chamber down to 10" and if I am right the elbow's would still be considered barrel length (I could be wrong) but doing what you said and cutting the barrel down would bring me to a C:B ratio of .67:1 with a barrel length of 57" (it is still 60" long haven't cut it yet and nothing is glued together yet or drilled for that matter) wold that work? Yes I know I'm sounding like a newbie but studying is diffrent then making it. LOL
