Making 4000 PSI BIG GAME PCP Hammer Valve

Part 2 of making my 4000 PSI BIG GAME PCP. In this video I built the hammer system, I estimate there will be 1 or 2 more parts, depending on how much footage I get. This functions great at 3500 PSI, although it would withstand 4000 PSI. At 3500 PSI the hammer functions better. In the next part I will be making the chamber, transfer port... etc

This is starting to look like a mix of Beeman chief and Smk B2 haha _And I love it._

[@pcpairgunschannel]

Maybe 🤔 I regret not getting a milling machine as I got a lathe, though. The slots on the tube for example arent quite precise, but in the end I will still have a very powerful small bore PCP. My next project is actually a regulated semi-auto PCP, and for that I am gonna use a mill and not just a lathe with a sloppy mill attachment. Stay tuned bro :)

@@pcpairgunschannel Cool stuff!

[@hunteranglin3750]

Can someone please get this man a tool sponsor

[@robertsimpson6324]

Thank you .have my new lathe coming to build this

[@pcpairgunschannel]

Keep me updated brother

[@adityasalunkhe1288]

Incredible build, good job 🐣

[@pcpairgunschannel]

thanks bhai

[@huazhong208]

Really beautiful.👍

[@sniperkota428]

Very Nice

[@airsight2753]

150psi/shot, wow! That's a powerful airgun bro.

[@pcpairgunschannel]

Yep! At 166cc. Expecting maybe about 50-60 ftlbs using 15 grain slugs. The valve throat is huge at 8mm and 5mm transfer port is pretty big for just 177

[@SuperFirewords]

Very Good Job but i wanna know what is length of a stainless steel tube in centimeters ?

[@pcpairgunschannel]

59.5cm, 595mm

[@SuperFirewords]

@@pcpairgunschannel Thanks bro you are the best keep going making the complete project 👍💪

How to do multishot chamber bro. Like rectangular

[@pcpairgunschannel]

multishot? sorry bro i am not sure what you mean. semi auto?

[@HamzaBendelladj-cb4np]

@@pcpairgunschannel yes bro semi auto

[@pcpairgunschannel]

@@HamzaBendelladj-cb4np You have to release air from the valve to the himmet chamber and not only to the barrel. Then the trigger needs to be so that when You press it down it releases the hammer but immediately goes back in place while the trigger is still held down. I actually plan to make a semi auto next. Stay patient, I’ll begin it in about a month

Pcp jawa

[@QILA_SLINGSHOT]

Mekanisme seperti buatan lokalan indo

[@pcpairgunschannel]

iya mas, saya mengambil inspirasi dari PCP buatan indonesia. Mereka sangat kuat dan memiliki bentuk yang lebih sederhana

[@whoami5228]

Seperti pcp jawa👍

[@VietHoang-sb2qg]

Áp 4000 thua sức công phá thua Cây tao áp 70kg/cm2

[@pcpairgunschannel]

xin lỗi, tôi không hiểu. 4000 PSI = 280 kg/cm2
