You know how most people use hot glue or epoxy to seal the schrader valve for their homemade airguns? Well has anyone ever tried using flex seal ? If so does it work?

I'd go with an old fire extinguisher if size is not an issue, I have one on my full auto vortex, I think it is rated for 450psi and there is a nice brass block on top to get a fitting in GUEST_0a7c7aa0-6c34-45b5-ace2-0a2ed00b17dd.jpg Will it work on a commercial blowback too with some modifying of ...

At a guess, that can's gonna be super thin, which would make modding it pretty difficult. I'd be more tempted to look at a discarded 60l oxygen canister or maybe a fire extinguisher CO2 recharge canister. Rather than modifying a canister, try talking to a local machinist, see if they can make up a ...

Hey guy's long time. anyways I have a question. You guys know about these gas refill cans for Gas blowbacks ? https://www.alibaba.com/product-detail/PUFF-DINO-Wholesale-1100ml-green-gas_60342662711.html Well i was wondering, if i took an empty green gas can and stuck one of these Schrader valves htt...

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...

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. I have animated it to explain the concept: https://i.imgur.com/cEQ1yC9...

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...

Hey guy's me again Ive tried a few design's and idea's for my homemade blowback uzi but they didn't work so well. So I decided to use a qev this one to be exact https://encrypted-tbn3.gstatic.com/shopping?q=tbn:ANd9GcTTE4lUtjnpS6IxJ-J2xkwNrblpyn5sxob2zCMU76pP5viKfH12k9dFP-8DaiUv9yUXF9k6qWeN4SI&usqp=...

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...

Also just a little side question if i use one of those mini pumps used for bikes how many pumps would I need to do to reach 12 bars?

You couldnt find the images? That's ok I still appreciate the links you gave I'll definately experiment with the designs a bit. Also I came across this blowback design today https://www.spudfiles.com/viewtopic.php?f=26&t=20754&p=283271&hilit=blowback+paintball+cannon#p283271 you think it would work ...

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 ...

Hi guy's I need some help. Im trying to make a fullauto replica of a micro uzi with a blowback engine and feeder. Essentially I want it to operate kinda like this commercial one https://www.youtube.com/watch?v=GokZcNx2dO8 but im trying to come up with an engine that uses no qev or electronic part's ...
