haha buon lavoro! simple standard parts and well put together :D

With the all-metal construction, I hope you're taking it to high pressures.

Of course it wouldn't be an Italian project without a shot at a Kinder Sorpresa type target :D

For a bolt and magazine, check out this recent tutorial: http://www.spudfiles.com/forums/how-to- ... 24038.html

Thank you!Damages shot are done at 10bar, that is the maximum pressure for qev,slide valve is rated for 16bar.

Just because it's *rated* for 10 bar, doesn't mean you can't take it to 30 bar :wink:
We routinely use small QEVs at much higher than their intended pressure with no failures. They're built for industrial use, so they usually have high safety factors.

Add a gun handle and clamp your trigger on to that slide valve, and it'll be a very comfortable gun to shoot.

Ouch, that barrel is a killer. There is often a seam down those iron pipe nipples. A nice 1/2" copper barrel (longer too) will be much better :) nice gun!

Nice! But I believ you could get away with a 1/8" paintball slide valve for your pilot. It would make a more comfortable trigger + you could then take the setup up to 500 psi with a nice safety margin.
