Very nice for a first effort! Chamber size is a little overkill but nothing wrong with MOAR POWER :D damage pics/videos?

Any pictures of the piston and sealing face set up? Nice work. That tennis ball looks like a tight fit, was that picture for size reference?

hey sorry for the slow replys been one of those weeks!
The piston is made out of so plastic bar that was at work with some o rings and rubber as the sealing face.

And yes this is my frist cannon it did have a ball valve on it to i made the piston for it.

here is the only vid i have of it

shooting a tennis ball from about 20 meters

Wow, haven't seen that until now. Dunno how I missed it. Looks excellent! I like the size of it. I suppose SB15 should be happy that a large bore has popped up, even if its not a hybrid or combustion.
