All QEV using air, some one have spring because the air "admition" is in front of the piston, the air want to recoil it bbut the spring holds it.

Without spring, the air come from behind the psiton and push naturaly it against the internal barrel, so we don't need spring.

For buildind, you can search ;)

Probably the same, but at least he wants to learn, even if that means making us research for him...

There is no way to tell how that one is made... just search through the showcase and you will get plenty of ideas.

All you really need is a lightweight body and a sealing face. Nothing more. Hot glue body and an inner tube sealing face secured with a screw will work just fine.
