Yes, Clide made a very powerful one a long time ago. Besides him, many other people have done it as well. Just make sure to sleeve your golfball barrel in 2" SCH 80, because 1.5" SDR-21 will implode when used as a barrel in a coaxial situation.

i like the whole innertube idea, but it doesnt work on anything more than about 2'' pipe if the tube is from a bike. if you truely have your heart set of using an inner tube, you need one from tractor or a lawnmower.
"physics, gravity, and law enforcement are the only things that prevent me from operating at my full potential" - not sure, but i like the quote

you know you are not an engineer if you have to remind yourself "left loosy righty tighty"

If you are planning on a full size and fully contained coaxial, that thing will be one heavy mother f'er. Good luck with this thing.
