Making an air gun trigger for 4000 PSI BIG GAME

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

Incredible build, good job 🐣

[@pcpairgunschannel]

thanks bhai

[@LowkeyAirgunner]

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 :)

[@LowkeyAirgunner]

@@pcpairgunschannel Cool stuff!

[@robertsimpson6324]

Thank you .have my new lathe coming to build this

[@pcpairgunschannel]

Keep me updated brother

[@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

[@Docv400]

A better way to thread a part with a Die in a Lathe is to put the part in the Chuck, put the Die in a Die Holder, then use the Chuck in the Tailstock to keep it square as you turn the Lathe Chuck.

thx bro

This type of 177 air rifle is very common in indonesia. The stainless steel tubes from motorcycle front suspension is used for this rifle. They're commonly filled to 4000-4500psi and can launch 20grains 177 pellet to 1100+ fps. People use this rifle to kill wild boar 🐗 which is pest here

[@pcpairgunschannel]

yep, i also got 1262 fps 15.4 grain. PCP Jawa

[@twitchclips3502]

Why don’t you use a regulator for your guns?

[@pcpairgunschannel]

I could, and I will. However for this project the idea was to just make it as powerful as possible in small bore, therefore a regulator is better to leave out. I will make a tactical style PCP later with a bottle tank, for that I may use a regulator.

[@twitchclips3502]

@@pcpairgunschannel Also how do you determine the right material and thickness for the pressure tube you use given that you have a working pressure in mind. Like what calculation do you do or numbers that you look at?

[@pcpairgunschannel]

@@twitchclips3502 Barlow's formula. Using the tube's outer diameter, wall thickness and material tensile strength you can calculate the burst pressure. Once you have the burst pressure, you generally divide that by 3 or 4 (depending on your safety requirements) and there you have the safe working pressure.

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
