I have now change the gun a bit:
-I removed the secondary chamber
-Reduced the pilotvolume
-Increased the chamber volume from 340cc to 460cc
-Added a grip and a screen to the gauge.
-Paintjob
-Improved piston
Old version:
This is my first airgun which I got to work fine a few days ago. Previously I made a potato gun but started to make this airgun because of my interest but also because ive got tired of my potatogun's unreliability
The idea then was to build a gun that can used 40 bar, got a 20mm bore and can fire multiple shots without hooking it up to the compressor al the time.
The gun has a 1 1/4 tee as pistonvalve, the piston is 3 cm in diameter and the sealing face has a 20mm opening. I have fired it up to 40 bar.
As you can see in the video, I have two chambers of the gun. The secondary chamber is way too small to fill in the primary now, but in my first prototype, I had a primary chamber of approximately 80cm3. Then I could reload and lost about 4-5bar/ shot. Despite the small chamber the gun was even when the much stronger that I could imagine but i wanted som more power.
The current chamber is about 320cm3 and performing far better. However, the secondary chamber are now useless. I will probably remove it and replace it with a quick connect so that I can link the rifle to a large fire extinguisher through a hose instead.
Things i will do:
replace the secondary chamber
reduced the pilot volume
ad a stock from a old airrifle
maybe a lighter piston, at the moment the piston is made of aluminum.
Some paintjobb.
Move the stupid placed male connect.
