Wasn't it easier to make a piston valve cannon? .-.

Can you send me the schematic of the coaxial?
Thanks

I meant like 1/2" thick plate

Yeah something like that, the only problem is that where i live i can't get any aluminum or brass

Is it possible to make the design i posted with a palm rest so i can keep my fingers in one piece made out of aluminum with steel inserts on the spikes?

I wanna get rid of terminator .how did you knew it?
Nah i just want something that i can use to hit wood, walls, maybe someone that attacks me without leaving any mark on the knuckles

Hey
Can someone help me please
I was wondering if someone could make one of this http://www.bladehq.com/item--Brous-Blad ... eel--17342 out of d2 tool steel or sk5 tool steel
Thanks
