I'd say more Tie-Fighter, less X-wing. But what do I know? *Drools on Star Wars Collectors edition*

Nice cannon by the way.

yeah, i tested it last night.

it goes through 8mm ply with ease, using a 3 gram potato slug

went straight through a 160 page magazine with a loud cack, it compleatly ripped the last 80 pages in half

through both sides of a tin can, really impressive, video coming soon

ripped the bark of an old oak tree

has a hang time of about 9 seconds with a potato

thanks for the comments,

When I read this post originally I didnt think that it would have this much power but appertly if a potato is able to rip through a tin can :!: Overall looks nice. Ill defently be looking forward to seeing the damage video. I know that hangtime has been a way of measuring power but I always forget to use it. It gives you a good idea of the power of the cannon not the power or density of your slug. Good job on somewhat varying from the normal copper pneumatic style.

Thanks Pimpmann, i wanted to have a launcher that had a large chamber volube but without the large size, so having 2 additional chambers added on to the traditional the 2 under the barrel helped tro achieve this. i think it may improove the air flow as well, but im not sure.

Iwas suprised with how powerfull it is, blew my mind after i shot through the tin can.

One this i can't stress enough is the improovment made by having all fittings larger than that of the barrel, 9in my case 22mm chamber, 15mm barrel), its really helps with the flow.

My old cannon, "the leech", has a 15mm connection between the 22mm chamber and the piston-T, its easy to see the performance lost due to this.

Thanks for the comments,
