[quotemore properly be called a volley gun rather than a machine gun?][/quote]
Of course you are correct, we "sexed it up" a bit in the title of the YT video to get more people to look at it.
"Volley gun" goes over the heads of a lot of folks who do know what a machine gun is, but yes, technically we're incorrect.
Here are all still pix I have, with the nice powder can for scale. You should be able to duplicate it pretty accurately if you want. I think I'd just tap and thread the rear ends of the tubes, and put a bolt in each one, instead of welding them up.
The thing weighs about 80 lbs. and doesn't seem to recoil at all, but next time out we're upping the powder charge and using bullets that will be a bit heavier. This time we only loaded one 9mm cartridge case full of 3FG powder in each barrel. I have a powder scale but haven't weighed the charge yet.
I didn't build it at all, I bought it at a gun show in MD about 25 years ago. I've had it out shooting I think three times since then. Next time I'll have bullets that fit better so we can do some real damage.
