Oh sorry, no I meant, the camera doesn't have a wide angle. Oh and btw, here is a pic of penetration at 250 psi...I just took it, my ears are still ringing
, now, each four box was placed one behind another, combining 8mm of wood. I also shot through the sides, they are 1/4" thick each, and the .25 gram BB went through two. To compare, a steel BB at 12 bars goes through three....I'll have the photo as soon as my camera is charged up!

Really nice build.
Have you considered to mod your blow gun a little bit?
The exit holes in the blow gun and the release valve are pretty tiny.
I drilled them larger at mine and gained a noticeable boost in performance.
Like the hose barb; I use them as well.

Well, for the moment, even at 17 bars, the "pressing" and the shot are almost simultaneous. I do not even have to press all the way it actuates pretty well.
Thanks for the comments guys!
it'd been a long time since i had built something i could be proud of ^^

That slow mo footage was great. It looked weird watching the ball "wobble towards that tree.
Looks like a sturdy barrel as well.
Keep up the good work.

Aye Aye Cptn!
I absolutely love the simplicity and sturdiness of this gun. Reminds me of my days with the "Mitcho's Musket"
Awesome damage vids too!

Dude great video I love the slow mo parts and the music also. Just an all together great video. Also I like your gun looks very simple, and straight to the point really cool.

Thanks a lot!!
I didn't want something overkill , just wanted it simple , high power plinker. I've done some more tests, with 1mm steel shot. You know those demineralized water jugs (5 Liters) well, at 250 psi, 3 out of four go through.
An airsoft BB goes through everytime.
I'll try to take a video of a supersonic shot, but it isn't everytime....sometimes it does it, sometimes it just won't. I think this gun will be the base for some upgrades, wooden stock, scope, green laser etc etc....

What is your piston?

The piston is hot glue with neoprene seal on top, and a screw to hold it there

Sweet, my valve with have very little pilot volume and a light piston, it will be interesting to see the difference

well, i have a very small pilot volume too...but the piston is pretty heavy, i guess yours will do better than mine
but no worry, i'll be glad to see your gun when it's finished
