Internal diameter 23mm. 11.5x11.5x3,14=415 mm2 (4,15cm2) 1 bar=10N/cm2 4000psi = 276 bar. So… you hold back 276x 10x 4,15 N =11454 N with a couple of little screws. Reckon with only one; they don’t bear equally and when the first snaps, then the second may well go too. Mind that the screw itself M6 has a core surface of 2.38 x 2.38 x3.14 mm =17,8mm2. If the quality is 8.8, the tensile strength is 800 N per mm2, starting to yield at 80% or 640N. For a shearing load as the screw experiences here, we take 80% of that value. We are then left at 512N/mm2 x17.8 mm2 or a load of 9113N at which the screw will probably fail. With 11454N … you are a lucky bastard. And please, dont grease O rings on a cloth full of chips.
@@lukmankhakim5568 the tube is 304 stainless steel, 27mm OD 2mm wall thickness. Using barlow's formula the burst pressure is 10958 PSI, and therefore the safe pressure would be 3652 PSI if we use 1:3 safety factor which is commonly used for air gun tanks.
@@lukmankhakim5568 Depends on the od, if you used a 27mm 304 SS tube like me, then 2700 PSI. 25 OD is more common for 1.5mm wall thickness tubes, for those it's 2958 PSI
When you use the centre drill bit and go to a bigger drill bit use the 3 points on the chuck instead of using one it will line the bit more accurate when drilling that's why there is 3 points to tighten it accurately
It's good to have the new toolsأ. Congratulations... great job. The best thing in the video is visualizing the sizes and dimensions.. Great work, keep it up and we are waiting for the rest of the manufacture of the air rifle from the reciger, the gun, and all the parts of all sizes and dimensions.. Greetings from Egypt
Many successful airguns do not use a thread. But they do not use Teflon, they use stronger plastics such as acetal, or PEEK for more strength. If the valve stem is very thin, a larger diameter metal insert can be pressed into the plastic, it does not need to be threaded.
Great work brother. I am also trying to make one but instead of gulb screws i want to make threads. So how much long the threads need to be to hold that much pressure and is 2 mm wall thickness ok or should I get 3 mm one.
2mm is good as long as its stainless steel Threads should be 2-3 cm long if they are 1.5mm pitch, make sure those threads dont see air by placing the o ring after them
my dad has a super nice bridge port mill and a ton of nice tooling I just started to learn how to use. I can make square parts and you can make round parts 😆
Lo siento en mi país el calibre legal es de hasta 6,35mm. Puede aumentar la potencia aumentando el tamaño de los orificios de transferencia de aire en la válvula.
Max psi per shot with the spring i use is about 10 shots from 4000 PSI to 3200 PSI, so 80 PSI per shot. 80 PSI per shot gives me about 70 joule, or 1250 fps using 15.4 grain. However I don't know what higher consumptions would give, I don't have a spring that strong to test. I think if you just try to bring the usage to like 500 PSI per shot you are gonna get at least 100 joule.
@@jandeeg152 yes, oils can combust under high pressure oxygen. But this is not pure oxygen I am using, its just air. Therefore combustion of the oil isn't likely
yes bro, patiently wait for the rest of the building videos. Next I will make a trigger and a hammer to open the valve, then later on i will continue with chamber making etc....
Very cool.. We are waiting for the rest of the parts: the Hummer, the receiver chamber, the Trigger trigger, the Hummer zipper spring, and the construction planters with sizes and dimensions.. Well done
that was just the unpressurized air bubbling away from the threads/what was between the valve and the tube. It's not from the tank. I have stored this for maybe a week at most while pressurized at 3000 PSI, a week later still at 3000 PSI.
I will, i can open it by hitting it with a steel rod like this, and it releases a good amount of air already (it may not seem like that in the video because the sound echoed all around). The hammer I will make definitely will hit at least as hard as I did with a steel rod

this is a very common way to do it. the grub screws arent the only thing holding it but the inlet valve too, which is a lot thicker

If possible, the valve shaft must use a thread to enter the Tevlon. Prone to breaking often hit by a hammer.
It's ok, this will work

You finally got a lathe, how much did you pay for that and what brand?
It is a vevor 7x16 mini lathe, it was 730$. Now lets see when I am getting a milling machine.
@@pcpairgunschannel same price here, make a mini lathe review, i am planning to buy soon.
@@airsight2753 let's see! 👍I'll be waiting to see what you'll make with a lathe!
So far, that will only blow away snow. Where is the rest of the 4000psi Big Game pcp rifle? LOL
Sir this is part 1, I will still build the chamber, Stock, trigger hammer etc
Di Indonesia This 2mm Monel material is made with 6 bolts and a pressure of 4500psi. 180cc cal32mm 8shoot 1100fps can be produced.
@@Pierchinggun i think 4500 psi is a bit too much. The burst pressure is 10800 PSI. depending on the steel alloy, of course.
Part 2 next please
in about 1 week it'll be done, still waiting for some materials to arrive.
thanks you br

You need a vacuum cleaner and a blow gun to clean up the chips. The amount of chips in your assembly area is frightening.
What kind of oil do you use for O-rings?
Silicone oil, or any synthetic oil. Petrolum based oils will destroy the rubber.
s.click.aliexpress.com/e/_Dl3RL1z
@@pcpairgunschannel Mind you, oil together with highpressure oxygen can be dangerous, you’d better use lithium grease.
BUT……., your video is great!
@@jandeeg152 yes, oils can combust under high pressure oxygen. But this is not pure oxygen I am using, its just air. Therefore combustion of the oil isn't likely
You asking for trouble using them little grub screws.
Next time maybe hydro-test the tank before you put air into it: if it ruptures when full of water it's not as .dangerous as when full of air
I hope you can translate it into Arabic because it is not available in the video settings. Thank you for your wonderful effort
I’ll look for time to add captions.
Good video but I'm not sure I'd trust that with 4000 PSI

You probably won't be able to get a hammer to open your poppet valve. It has too much surface area and pressure pushing against it.
I will, i can open it by hitting it with a steel rod like this, and it releases a good amount of air already (it may not seem like that in the video because the sound echoed all around). The hammer I will make definitely will hit at least as hard as I did with a steel rod
