Air Cannon - Pfft!

[Devilgate]

Hi All - I made myself a brilliant air cannon with 32mm PVC pipe.

It easily fires a 340g bag 25-30 metres into the air with only around 35-45psi. Refills with a standard car valve.

The actuating valve is also a full-bore 32mm, which cost a bit more to get, but well worth it.

I'm so chuffed with it, that now I'm wondering if maybe there's a market to make these - or perhaps put together a kit that includes everything for you to construct it yourself.

It's not just a straight pipe design like you normally see. It's a bit fancier than that.

My first question is - what would you be willing to pay for one?

Hmm about 75 foot pounds of muzzle energy

Thought they were made illegal because you could fire anything, potato, tin can of soup etc ?.

Do you need an FAC for that ?

What's the legal position of those air blaster things down the tyre shop?.

 

As one would presume you could just pop a section of drain pipe on it and bang goes the Duracell bunny.

Its been done . Any workshop with a compressor and an air line . Done it my self back in the day . Brazed the screw on tip from an air line gun onto a bit of stainless tube . Made a dart out of a small paint brush handle with a spike on the fat end . Two rolls of insulation tape around the shank to form a seal . One squeeze of the trigger for half a second and you got a very fast projectile sticking in a plaster board wall . I was only 16 years old in my defense .
