Thread: legaly speaking....... mini canons?

Youtube has excellent oxygen bottle ( welding type) cannons that fire bowling balls.

High pressure pipe used in hydraulic rams are probably strong enough , you can shrink reinforcing pipe over the breach area if needed . If you can get some , railway waggon axles are supurb steel , bore them out for a morter

Yes, it was bugging me.

To save me looking it up, how do they define an antique firearm?

That would be nice and smooth and round and constant diameter being ground.
Shed 80 pipe could be another option.

It will split.

Shed pipe is seamless. Used in high pressure steam,flammable,toxic etc.

Yep shed pipe is seamless, I use shed 40 for mine but I only get to a max of about 1500 psi

oooh I might have a length of stainless pipe came off a sonar, wonder if that would be strong enough.

@spanners think I read somewhere anything over 20mm is a canon...cant remember where off hand.

So my tiger tank's 88mm is fine then....

Yes I know, some people reading this may not and may end up using any old pipe.

Plug Welding the chamber when using Seamless pipe is critical and will create a weak pont in your cannon ...

One thing you dont want is your cannon going at both ends at once.

you guys are insane....

antique firearm means—

(a) any firearm that—

(i) is held in the possession of any person solely as an antique (but not as a copy or replica of an antique); and

(ii) is not designed for firing, and is not capable of firing, rimfire or centrefire cartridge ammunition; or

(b) any firearm declared by regulations made under this Act to be an antique firearm for the purposes of this Act

There you are Gimp , It used to be an antique if it was an old gun that ammo wasnt currently being manufactured for . Lots of us had 455 pistols , then Fiocchi started making ammo for obsolete firearms and the 455s etc went on ticket . Then an idiot got a pistol for home defence , it was an old French prototype revolver , and even though there was no ammo available it shot with 450 corto ammo , which expanded into the cylinder but still worked , there was a court case when he treatened his girlfriends husband with this gun , and as the jury couldnt understand how a gun could fire ammo that wasnt made for it he got off , so when the law changed they lumped everything that takes a cartridge except pinfires , onto an appropriate licence . If you have a muzzle loading antique rifle or shotgun you dont need any licence unless you are going to shoot then an A applies .
