Re: Valves
Welcome to the forum! Are you regulating the CO2 or using it at full pressure? If you want something off-the-shelf that is reasonably priced, a Quick Exhaust Valve is your best bet. some eBay links: https://www.ebay.com/itm/New-SMC-NAQ5000-N06-3-4-Quick-Exhaust-Valve/184577915583?epid=1111890803&has...

Re: 2 Stage Pressure Release During Firing
Welcome to the forum! Are you thinking of an air powered version of the Vergeltungswaffe 3 ? https://i.imgur.com/b6axwmYl.jpg If so, I think it's an unnecessary complication. Apart from the difficulty of triggering the second valve at the right time, if you want sustained pressure in the barrel you ...

These hybrid-pneumatic circuits you manage to make work never cease to amaze me!

Re: 4,2 mm pipe for 4.5 ammo
They have some good effect because of their sheer volume, same as a 2 liter soda bottle, but are definitely impractical compared to a proper series of well designed baffles.

Re: Agitator for a BBMG
It's something I've often pondered but never actually made. Here are some very old (2004!) concept drawings, at the time I was interested not only in reliable feed but also having a way top control the rate of fire as well as reducing wasted air. https://i.imgur.com/OhGHs9R.jpg https://i.imgur.com/m...

Re: High pressure air pump
Very nice!
Does that mean we will be seeing some ultra-high mix hybrids in the near future

Re: is this a hq hand pump ?
I've never seen one in the flesh but most people seem to think it's pretty good.

Re: 4,2 mm pipe for 4.5 ammo
damn, I never thought to look
I wonder if it would prompt a visit from the powers that be as it goes through customs...
The same has been happening locally with so-called "fuel filters" that have become widely available.

Re: 3D printing?
Yes i was going for a coaxial design the small groves were to allow the chamber to be filled past the piston or an equalization channels as there is none on the piston itself and a spring would also be used to aid in the sealing of the piston You don't need them, in fact they are too much and it wi...

Re: 3D printing?
Welcome back! The material advances in 3D printing in the past few years have been amazing, what previously I thought would have been impractical for structural parts is now feasible. Regarding your piston, doesn't it need to be cylindrical in order to fit in a tube and remain airtight? If air can f...

Re: I got some questions.
I was even debating placing a "silicon desiccant pouch" in the chamber to absorb excess moisture.. I figured it would end up fired out the barrel so I have not messed with that yet. There are commercially available solutions that you can attach to your pump: https://www.pyramydair.com/s/a/Hill_Scre...
