As for your HPA paintball tank, do you know if it's configured for what's called a "high pressure" (usually 750-800 psi) or "low pressure" (usually ~450 psi) marker? Because you are unsure if it has a regulator I assume you do not have an external or adjustable regulator. Paintball HPA tanks much of...

I've been working on a new golfball gun and in an effort to ergonomize I've been trying to figure out the best way to reduce (hopefully eliminate) the distance between the chamber and the barrel while maintaining the pressure bearing capability/functionality of the valve. The valve will be used at 6...

it could be achieved using pressure area differential but I think there is a spring there... in the vid you can see that it returns to original position even when not under pressure so there must be a spring But if all the portings (nipple inner diameters) are the same then there is no pressure dif...

How exactly is the pushbutton (spring return) effect achieved without a spring? Are the diameters of the exhaust porting and the front seal not the same? ie. is the valve not balanced?

I use lithium grease as well. From what I've read and seen it plays nicely with all of the most common construction materials used in spudding; pvc, cpvc, abs, metals, o-rings of various material

Does it still shoot nerf darts?

How did you modify the co2 bottle for the 1" porting? Is that welded? I've been wanting to use a repurposed high pressure tank as the chamber on my next build, but the tanks most easily available to me have threads smaller than I'd like and I'm not sure I have the resources for metal work. I know ot...

Any links clemsonguy? I've seen some that use aluminum tanks or other repurposed aluminum, but not any like this. Somebody even posted a link to a "light air tank" I think they called it that someone had constructed out of aluminum soda cans and some sort of epoxy. If I recall correctly he took it u...

I'm sure many of you have seen these aluminum water bottles around. http://parsonspr.files.wordpress.com/2009/08/aluminum_water_bottle.jpg I was wondering what your thoughts are on the use of one of these as an air chamber in a pneumatic. What kind of pressure do you think it could hold? I looked ar...

Thanks for the help everyone.

Clippard also makes and sells a number of pneumatic valves, particularly small ones it looked like to me.

I think this is the right place for this, but if it's not then sorry, please move. Has anyone had experience with the sleeve valves Mcmaster sells? (ex. part # 4622K55). I think I saw one on somebody's gun a while back and there was a video but I can't find it now. Anyone know how the flow of a 3/8"...

Looks like I'll just buy a bunch of parts that I may or may not need ,to see what works and what doesn't and spend a lot more money on this project than what I had planned. Basically how my cheap weekend project has turned into a year-long more than $350 investment. Sometimes it's fun to reinvent t...

I've used threaded plugs in the past, which work, but I've had trouble with them leaking, especially after screwing and unscrewing several times. I'm looking for something more consistent and more easily detachable, so the back can be taken off for storage.

I'm trying to figure out if I could use camlock fittings on a tee piston valve to make the valve serviceable. I'm not very familiar with camlock fittings and would just order some and see if it works but I don't have the money just to see if it works. Would it be possible to thread a camlock fitting...

One reason I think DCVs aren't more widely used is their lack of availability to many. I know McMaster has a selection, ebay has been hit or miss for me, and googling hasn't really yielded any good results. Do you know somewhere where you can order DCVs online?
