PART 3 of making the 4000 PSI PCP, as you could see in the start, this reached a really high velocity. In this video I showed the making of the chamber, the bolt, the pusher, seals for the brrl, 1/2-20 UNF adapter... etc. However, I ran into some problems with the milling attachment, the finish was simply unacceptable, therefore I kindly ask you to support my channel so I can buy a mill and make more satisfying videos for you guys :) Fund my projects: !!!
