My mom told me to clean my room and I found out I have a couple of QEVs, 3-ways and cylinders all around, I thought I´d make something with them and my friend had just got me some 12mm steel BBs.
So I made a simple .50 cal semi-automatic using 1/2 inch stainless steel tube as the barrel. It works like the most basic 3-way+QEV+pneumatic cylinder semi-autos, the cylinder it´s connected to the chamber of the QEV and it´s used for reload.
Any question just ask POLAND_SPUD

Thanks Jack Well as soon as they can get a air source to power this thing also if 3-way valves aren´t that difficult to find on ebay

How much did the push lever 3-way and air ram cost you? Stuff like that is so expensive here.

is that a single or double acting ram??
Posted: Thu Aug 30, 2012 5:36 am
by wyz2285
Double, but a single one would be easier to use.
Posted: Thu Aug 30, 2012 5:38 am
by CooperJS
why would a single be easier, are there any differences?

single acting rams has a spring to help it to return to it´s oringinal position while double actiong rams has another input port, you need some air to push ti back to it´s original position.
