Modify pop off valve

Hey guys long time, so I decided to use a pop off valve from Amazon https://www.amazon.com/Compressor-Safety-Relief-Pressure-Valve/dp/B01I57DCCM/ref=mp_s_a_1_1_sspa?dchild=1&keywords=air+compressor+pop+off+valve&qid=1596234487&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExRThCN0hIVjVTVjBVJmVuY...

Re: QEV blowback mod?

it is much better to make the drummer cock up with air that leaves the pilot valve. That works too and is especially useful if one were making a big-bore repeater where too much air would be wasted cocking a direct hammer valve.

Re: QEV blowback mod?

What exactly do you mean by "blowback action"? Do you want the QEV to also operate a self-loading mechanism? What I mean is I want it to kinda operate like Wen's for example https://www.youtube.com/watch?v=z9dmmX9Krfk as you see at the end of his Qev he has a tube with a plunger and spring and if y...

Re: Help with making a diy blowback system

Here's a quick sketch at what I'm aiming for. I also went ahead and drew the custom airtank( modeled after a commercial one) that I made out of a soda bottle ( the large ones), a ball valve , an air tube, and a threaded end with an o ring attached for the Blowgun. So essentially its like how I descr...

Re: Help with making a diy blowback system

HMMM The second link might work I think i'll experiment on that one, also on the second link there is a pipe in the center of both the airtank and the barrel with the blowback, if i just put a straight tube going all the way to the blowback syatem would it still work? Also some of the images aren't ...
