Compression fittings are two 1/2 extensions and I was only having 1/2 rubber washers that have 6 mm ID and the nail diameter is 5mm. I want use that valve for 100-150 bars , maybe less. Yesterday I putted 2 rubber washers in compresion fitting and air was not leaking but it wont move without lubrica...

Hi , i liked pcp airguns and decided to build one but i dont like style of normal hammer valves. I decided to try build a hammer valve where I can put the barrel in front of the valve. I builded something like this on the picture. Air is escaping like sieve from the back where is the squished rubber...

What if i will remove magnet detent and I will make ball detent?

I have tried similar and it will always happen like that, there is too much air just to launch one BB, it will try to launch the next one or two at a reduced velocity, so they just roll down the barrel. If you want semi auto you need to block the magazine tube somehow between each shot, that's the ...

Hi guys , Happy New Year :D . As always i have problem... I just started building a 4,5 mm BB Semi auto Airgun , but the magazine doesnt work that i wanted. QEV is piloted by 1/8, 5/2 solenoid valve converted into 3/2 NO. Magazine is gravity feed (with spring the same happens) and detent is a magnet...

Hi , short questions Can I connect this two 4,5 mm barrels in one longer like this? I have short barrel and I want now it little longer. I will just put this two OD 6mm tubes in one 6 ID tube. Will it work? Will it ruin accuracy? Can the power decrease?

Hah, I watched all his videos last time even liked them all. This guy is doing great job , I'm curious what is the highest pressure that he put in this tank. I also want to know more about this side lever.

I have paintball bottle which has PH 300 bar and there is on bottle tap about thread size. It say 5/8 18 UNF. I tried 5/8 thread and it's too big for it. bottle only fits 3/8 but for 2 tooths.

Thanks. I don't see on bottle any words about mix.

Hi everyone. I want show you my Potato gun, what I made. For me it is little ugly. I need to clean it but it works and it is fueled via 100 ml syringe :D btw sorry for my bad english. I fuel the gun from syringe using 100 ml of propane-butane and cannon never almost failed. Is it good ratio of fuel?...

Nevermind i think i will not use ball valve. I just found a pcp one way filling valve for 10$. Something like this

Ok thanks for info

You're right. I think i will buy high pressure rated fittings because i dont want risk. I even found that 250+ bar rated tee costs less than this 25 bar rated tee... How about 3000 psi rated aluminum paintball tank Can i take it to 300 bar?

So it wont be able to hold that? I found that Joerg Sprave was using ball valve rated to 150 psi and it was able to hold 200 bar.

I have another question. Will this steel tee and ball valve hold 200 bar pressure? Steel Tee has pressure rating to 25 bar. Brass ball valve has 30 bar rating.
