Very nice!!! Btw, try using PEEK instead of Delrin for the valve poppet next time. It’s harder to get a good seal (use the same method you do now) but you can crack the valve open much easier as PEEK doesn’t deform like Delrin against the seat, which also allows you to use a larger valve throat.
@ yes, for the same amount of force from the hammer the PEEK valve will open more compared to Delrin (specially with higher pressures). I use around 80% of bore size for all ports, except the throat where the equivalent area (stem area - throat area) is about 90% of bore size. Anything above a .30 caliber it gets harder to open the valve (heavy hammer + heavy long spring), so I’ve been making balanced valves instead where you reduce the closing force on the poppet by having an internal “piston” exposed to outside pressure. It gets fun from there… there’s a lot of info online.

Pretty slick. Why water? To “my mind”, now gotta get moisture out. Why not use nitrogen and getting any moisture out from atmosphere at same time. No finding fault, simple curious from my experience of “ things”. 😁🫵👍 Lathes are cool
I had to fill it with water so that there is very little volume left for air. It's for hydrotesting, to see if the tank can withstand it. The water is easy to dry out, I had to disassemble it anyways for continuing the project.
wow pcp air gun boi back :0
Benjamin Marauder based?
@@BernyAV yes I am copying the marauder design for a semi auto
@@pcpairgunschannel Very nice.
Hope you could do a video on how the semi auto function works.

@@pcpairgunschannel Yes sir, I have watched this video and I must say, you do impressive work sir.
amazing like always !
Good stuff man😁👌
The video just popped up for me🤔 I better turn on notifications!

So its easier to open? Sounds good!

@@RJ-re4lj I am actually planning a 80-100 ftlb .25cal. I will definitely use a balanced valve for that, otherwise it would need crazy hammer tension
Gut gemacht 👍🏽
Please make a video making of 4500 psi air rifle tank
maybe
Higher pressure isn't always better but if you balance it it is fine.
Trabalho excelente
👍👍👍👍

Hola que marca o que referencia de torno utilizas, gracias
Vevor 7x16, the link is in the description
@pcpairgunschannel gracias,eres muy amable
Hey man what Mill you use
Bernardo KF 20 L
@ oh wow i just orderd the Bernardo kf25D.Bernardo realy makes some good machines
Why rotate spindle by hand for making thread
I need slow speed, on A mini lathe low speed has too little torque And wont cut
@pcpairgunschannel thank you for your information. Your design pcp seems like pcp in my country indonesia
@@USLUGHUNTER Yes, I think there are many Mouser type air guns in indonesia. This is like the benjamin marauder
Mantap
Is This cylinder not in danger of bursting?
No, I calculated what it can withstand
👍👍👍👍👍👍👍👍👍👍
👏👏👏👏👏👏👏👏👏👏
Wie lang ist die rohre ?
60cm
@pcpairgunschannel Und wie ist die länge von dem eingang der luft bis das druckventil ?
@@MarouaneLM 41.5cm, 220cc
@@pcpairgunschannel danke für die informationen 🙏🏽
Noch eine frage : Ich machte eine, aber das Geräusch der Explosion ist laut. Deines Erachtens warum ?
Full stenlis or duralumin
Stainless, valve brass and aluminium
How to make to order with you sir that airgun valve and cylinder…
Its not for sale, sorry
用的钛金属管，还是不锈钢304管
Se daño al final 😂😂😂
no damage
@@pcpairgunschannel no quedó en 0 psi
Can i buy ur item
sorry, it's not for sale and i cannot ship it due to courier policies. it is just for entertainment

漏水了吗，这个结构全靠密封圈承压，不会太可靠
@@haichen7693 no leaking
it`s normal to test with water because if the pipe burst it`s less energy. no ¨explotin¨, because u cannot compress water
