My first ever pneumatic rifle!
Materials:
- BB rifle barrel, 6,03 mm ID encased in a 1 cm brass tube
- green gas container
- schrader valve
- piston valve inside a 1/2 T
- ball valve
- blowgun
- wood

It's still a work in progress as I only have time during the weekends.



As you can see, at the moment the barrel assembly is taped to the gas container until I manage to figure out how to improve my wood carving skills



Operation is quite simple: turn off the ball valve, pressure the chamber through the schrader valve, pull the barrel, insert the BB



push the barrel back in place



turn on the ball valve and ready to fire.
I hope to finish the loading mechanism this weekend (that is attach a pin to the barrel so I could manipulate it easier) and the buttstock





and then I can sight it properly and show some damage.
At 7 bar a 0,25 g plastic BB almost penetrated a 3 mm solid aluminium plate from 10 m.
Feel free to help me improve the BBinator

OK, some damage pics:
7 bar, 0.25g BB plastic, distance 2 m

The dent in the upper part is from a miss (yeah, I wear glasses )

Looks good, how did you attach the green gas container to the ball valve?
By 3mm aluminium foil do you mean kitchen foil or solid aluminium plate?
If you want to make a simple barrel support you can have a look at the cannon in my signature, the barrel support was just made with a pice of wood and two holesaws.

nice but

Oops, my mistake for not being clear.
I drilled the gas container, screwed the ball valve and the schrader valve and used a lot of epoxy to make sure there are no leaks.
As for the aluminium foil, you have to excuse me, English is not my native language, I mean solid aluminium plate.

Well done on the gas container, I gave up on trying to attach something on to one of mine
Aluminium plate Nice!

nice , where did you get that blowgun ? i want one exactly like it haha

The blowgun is from Praktier, a local DIY store. It's a cheap model, rated for 10 bar max.

"BBinator" good name ,
remind me about Phineas and Ferb
i love it

I have a 7 yo daughter, where do you think I got the name from?

3mm solid aluminium plate? at 7bar with a 0.25g bb? I need to see it but as that big chamber only delivers one shot, I guess it´s possible...

I hope to upload some pics and maybe a video this weekend so stay tuned.

I like it! Very cool. But I doubt the 3mm aluminum plate penetration

It didn't penetrate. I said almost penetrated.

What does almost penetrated mean?
