Black Friday sales soon, got to be some deals on 3D printers. I got my Ender 3 1/2 price in a sale. Started with PLA, now printing stuff with PETG.

I remade it again into semi auto airsoft, no moving parts, it just blows the BBs up the ammo tube.

I wonder if the solenoid valve also needs pilot air to operate and as it starts to dump theres not enough pressure to open it. I have blocked and redrilled pilot ports before so the solenoid part always has full pressure. If the valve has a manual actuation button on it have you tried firing with th...

Some build pictures and parts. Trigger valve, 3/2, is threaded straight into chamber, 1" stainless steel Sch40 tube, and piped to air pilot valve. 20220429_065634.jpg Grip is made from old kitchen table top.

Watch this first

I stripped the rubber off and soldered to a NPT fitting, or you can buy them

There is a downloadable PDF for it

I like both of them, I would like to see exactly how that airsoft works, 477 fps on the chrono seems ok to me for what is.
OK, so apparently it's a 0.25 steel BB gun.

Running at upto 600fps @150psi, stainless steel barrel and chamber, 1/2" pilot air valve triggered by miniature 3/2 button valve, all hand made except the scope, PVC pipe for muzzle break. 7 shot gravity fed magazine tube, single shot bolt action.

I like it, what's the magazine capacity ? That's why I made my vortex hold 2000 bb's

I use those little button valves for triggers as well to power air pilot valves.

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
