My friend has long been interested in medium and high pressure pneumatics. Just like me, she does it with the help of plumbing and simple tools. For example, here is one of his guns. This is a coaxial circuit, caliber 20 millimeters, pressure 40 atm. Homemade fully in the style of this site.

Strange, it is impossible to attach a video, only the link.

[youtube][/youtube] And what can you say about such a gun?)) The pressure is 120 atm, the barrel is smooth, the accuracy is 20 cm by 20 meters. A balanced valve is used.

Years ago I was close to marrying a woman from Siberia, this is like a glimpse into an alternative universe of what my life would have looked like :D

But what I did. A pistol with a balanced valve as in the picture. I pumped up and 100 atm, but the best bullet speed starts from 70 to 50 atm, from 160m / s to 130 m / s. The number of shots is 30.

Impressive the two weapons. Really very inspiring for me :bounce: . The simple and effective construction, and with limited means, is the best. Excellent post regards :)
You can use a neodymium magnet so that the ammunition does not fall.

Very nice! The vertical valve reminds me of the Weihrauch HW40/Beeman P17:

My friend made another gun. It is made of a fire extinguisher, the valve is balanced. He made her keak toy for his younger brother.

That looks like it could be a very dangerous "toy" at higher pressure... still, looks well made!
