I already have a CO² kit, the regulator was to act as a secondary one for finer adjustment :) Its this one: https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSOffC5eXxeVk0BXG2R6etX8wPqxtZIm3FtL6BasWxy0Gm4MZtG The coil hose was removed for a straight 6mm line which lead to the secondary reg, the ...

So it's basically a tap? I've already called the shop and i can bring it back within a few days. I really just need a small regulator. The final product is a small CO² rig for a converted airsoft gas sniper rifle ;) Only problem is that i tapped the inside of one of the 1/4 exits for 1/8... So no ch...

So i bought this thing at a specialized store, its supposed to act as a secondary regulator for a mini CO² rig. But here's the ting, it wont regulate... When i hook it up to the setup and turn the knob only SLIGHTLY the needle literally JUMPS to 7 Bar, and when i turn it all the way open it still si...

Just a little update on this, i recently removed the entire pilot valve "assembly" and replaced it with a solenoid valve to act as the pilot valve. So yes, it is now electronically triggered :wink: It is still in a prototype status, but it works! I wanted to post some pictures but it looks kinda mes...

Regulate compressor to desired psi, muzzle load projectile, attach quick connect, open tap until chamber is full, close tap, disconnect air line... point and depress tyre chuck to fire. Also inside the 1/4 T-piece i have stuffed it with 2 short lengths of nylon tubing to drop the pilot volume, foun...

That's the pressure you are using? because I'm trying to find a regulator that's possible to get a output of +-10bar. I could mod a standard paintball regulator, but I would prefer a factory made one. I simply use a Palmers regulator, which i use for powering a few airsoft guns, and for now this ca...

In order to avoid breaking my pressure gauge on my HPA rig, i removed the gauge and screwed in a 1/8 plug. Therefore i had to rely solely on the mini gauge which was on the extinguisher valve :roll: http://i703.photobucket.com/albums/ww32/alex45569/DSC01184.jpg I filled it until the needle went past...

Bush the pilot side of the qev down to 1/4 and use a simple tyre chuck to pilot the valve. My wife was having problems firing mine so i simply used a bit of leccy tape to stick a larger ball bearing so it is resting against the chuck valves nipple. made the inny an outy trigger :lol: edit.. ps.. ni...

Nope, unless i keep the HPA rig connected between shots because it will keep supplying air

Well like i said, when i open the valve it just goes boom I can't seem to hear any noticeable delay when shooting it, unless i open it slowly. Its pretty much like pulling the trigger on a rifle. Not squeezing it of course

Hmm i can't really guess the size of the port just by looking at it, but maybe this pic will help to make an estimate:

Thanks for all the nice replies! I have a picture of the CO² cartridge compared to a normal 12g cartridge: http://i703.photobucket.com/albums/ww32/alex45569/DSC01189.jpg http://i703.photobucket.com/albums/ww32/alex45569/DSC01190.jpg As you can see, its a nice fit :) And i found a damage pic for you ...

Hi there. Although this is not the first cannon i ever built, the other two were the manual chamber-ballvalve-barrel type. Which was fun for a while, but this is my first more "advanced" attempt at this :D And English is not my native language, so i hope my writing isn't too bad :D http://i703.photo...

Haha what a coincidence! Well i just ordered myself a 3/4 QEV (European type) For my latest project. If it turns out nice I'll post it

Thats it alright, no doubt about it! Bummer, that means it has little to no use for me now

Thanks anyways guys!
