if it does fail just get a peice of plastic or metal and cut it to size and drill a hole in the middle, thats what i have done several times so that is exactly the right size
also you might want to sand down the 2inch nipple so that is smoother for the orings to seal on
and filling twice with air might get annoying

Damn, thats a nice piece of kit. Very nice job. Well, theres no turning back now. Piston hybrids are coming of age and are set to become more common. Thanks for showing your internals. This helps me understand more about just how this design functions.
Consider incorporating a check valve attached to the piston somehow. I heard someone else mention this idea before. This would allow you to pressurize once through the pilot, pressurizing the pilot and chamber with no combustion force being able to enter the pilot area. It might not be able to be incorporated with this design, I don't know. Just thought i'd throw it out there. Very good job!

Aren't you afraid of the hit in your shoulder? I mean, first tests obviously are fired remotely, but after a while you're gonna shoot it as i is meant to.
I would be scared...
I remember of the hole punch i shot and...i took me off my feet. Might i add, my hybrid does not come close to the level of energies you're playing with...
Be carefull

Mabye start with something a bit lighter, i get a pretty big kick shooting 50g of lead at 300psi and i have a 1 1/4 inch thick wood stock.
what dia is you meter/stock?
At least get a vid of you shooting, if you get knocked over put it on Funniest home videos

well technically......you'll probably need to go heavier to obtain that recordSpudBlaster15 wrote:So long as everything works as it should, the 160g battery slug should give me ~3200ft-lbs of muzzle energy at a 5x mix. Possibly the most energy ever obtained from a shoulder fired spudgun?

Good job SB, might I ask what the "incident" was?
You should try to shoot a light projectile at a watermelon. It is damn fun!
I guess this cannon reaches higher energies, it's a hipfired cannon though.

Oh, and don't you have a worry about something causing the piston to come out of the tee and into your eye? That would be quite nasty.
