I have been looking into making “Airsoft” guns, an interest I got from my grandson Ethan (who made an impressive gun of his own.) As I checked things out, I found guns that had bigger bore and shot darts, marbles and other “ammunition.”
It would be fun to make a little more serious PVC gun. Some are even using them to hunt small game.
The biggest problem seems to be the trigger. It must be able to contain air under high pressure, and release it very quickly. One inexpensive “trigger” uses a ball valve (show to the left.) To fire the gun, the user must move his hand up to the valve and quickly twist the valve open. This motion tends to jerk the gun, impacting the aim. I found a gun with an actual trigger that releases a spring that flips the valve. Could work.
The gun in the picture in this post uses a sprinkler valve. This approach is touted as being effective. But the added complexity to integrate it and the cost (about $30) makes it less then appealing to me.
So, how about some ideas???? Surely there is some way to make a simple, inexpensive trigger. Once we come up with it we can explore all kinds of fun air guns.
Here is the plans for the gun above: 25MM AIR GUN PLANS
