Ok thanks Crna.

Lab, excuse me for wanting to know...

Jhalek, I would give it a shot if I had the stuff to do it! If you have the stuff, definatly try it, it would be awesome plus the bang it would make.

Crna, if it takes 900 psi, you should use unregged co2. It would be incredibly powerful, and make a fun little toy.

sorry for dubbel post. i case hardened the blade and it worked out all right but the blade look crappy so i sanded it smooth but by then the hard case was gone lol. so i just glued it up at 12ish ill get a vid up.

i found this forum about Prohibited Weapons in nsw the, if you read the second one

(2) A ballistic knife that propels a knife-like blade of any material by any means other than an explosive.


does that mean if i make it i hybrid it would be legal in nsw?

In all honesty, you don't really need to worry about this being illegal, i very much doubt that the police are going to come knocking on your door (excluding some cases) If you use it responibly, everything will be fine.

A hybrid is a mixture of gases so that would not count as an explosive.

im not worried(hope i didn't just jinx my self), it was more for the aussies that don't want to make one because they don't wanna get caught, im sure if the cops did come id get in more crap about the semi then this anyway.

Crna, if they do come, just make a rounded off endcap for the schrader that completely covers the entire end of it, making it look like its explosive powered.

Check the how-to section, I saw something there that used jello or something for ballistics gel. Nice shots with that by the way. Which do you recommend for charging them up to high pressure, a fridge compressor, or a shock pump?

Nice. Well since my foot pumps gauge broke off, I guess I will just use the hose from it on the fridge compressor or something till I can get a better one.
