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!

Ironically, an off the shelf oil filter, intended to be used as such, might well do a better job.
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 :D

I've never seen one in the flesh but most people seem to think it's pretty good.

Rifling buttons are cheap on aliexpress. Just saying, like.
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...

I'm not going to say that connecting a few turns of conductive wire to the spark plug, and a small appropriate battery, is another option because you will fuck me! :o

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...
