Regulated SEMI-AUTO PCP Valve Hammer Recovery system
Вставка
- Опубліковано 3 жов 2024
- Part 2 of my semi-auto PCP, this uses a 1800 PSI output regulator as well for consistency. In this video I showed the recovery system, how the vent hole releases air towards the hammer for another use. However, I had an issue, this was only consuming about 7 PSI using a 0.3L tank, which is not good enough for semi auto. I could connect the bolt with the hammer and make it an open bolt system, but that's not what I wanted. Due to this I will not jump right into making the chamber, but instead I will make a new valve. The current valve has a 6.8mm throat diameter, so it's quite hard to open. The new valve will use a 5mm throat diameter, so it will be much much easier to open, and it will likely reach 20 PSI consumption.

Every bit helps keep the creativity flowing!🔥Thanks so much for all the support lately! 🙏
Great project. Amazing execution. I made a custom semi-auto PCP with similar project too. For more air consumption you can use a softer valve seal spring, once a havier hammer&spring might lead yours semi-auto cycles to fail. 4.5 to 5.5mm transfer port will also gives you away more joules. For me the chalenge on semi-autos PCPs is get it still properly cycling even at high energy configurations.
I have to decrease the valve throat, its 6.8mm so it requires too much hammer spring tension to open enough. I will use a 5mm valve throat for the new valve, it will be much much easier to open. I am trying to get about 25-30 joules and not more because I Dont want to get that sonic boom because it causes disturbance
I got it. Mine gets 42 joules with a 7mm valve throat and 5mm port. I'm working on it to achieve ~70joules by constructing a balance valve. I don't expect to my semi-auto to be more accurated than a monoshot pcp anyway. So I'm goind for the powerful ones.
Your videos are popular here in Brazil! Even in PCP shooter groups on WhatsApp!!! Congratulations
Interesting 😅
@@pcpairgunschannel What is your country? For curiosity???
@@pcpairgunschannel No wonder, you make quality educational content. Is making own air tank any better than buying one? Or is it just for it to be cheaper?
@@arielsgood4972 its for customization, but some may do it because its cheaper.
very useful knowledge,my brother,there is not a singgle channel that discusses this,y still want to know more about semi auto and full auto mode lever,my brother,always healthy and always successfull
👍❤
finally the video I've been looking for has been made by him..Thank you for sharing your knowledge, you are a genius
👍👍
Your a brave man using that angle grinder like that
super nice job as usual !! never stop
..good design on the trigger.. nice work!
Thanks! Hopefully I will also increase the air consumption with valve mods.
Great work , thank you for the videos
Nice work
Congratulations on your channel! The best homemade pcp I've seen so far! I'm from Brazil, and PCPs are very expensive here, I liked your project, can you do one explaining the semi-automatic valve above?
Thanks!
There is a vent hole behind the valve, which flows air to the hammer reloading it.
You can see how the trigger works in this video
@@pcpairgunschannel Thank you and your channel is amazing! Like and subscribe!!!!
Hello everyone,
If you have any requests/ideas for me about what videos to make or what projects you want to see, you can give suggestions here.
Very, very wonderful work.. but I hope to activate the translation into Arabic. Activate the demos.. We are waiting for the rest of the receiver, the magazine safe, and the installation of the pipe that I manufactured some time ago.. We hope to make a one-piece side lever receiver with the hammer and valve soon.. Greetings from Egypt.. Thank you very much, well done.
@@ameenattef469 Hi, there is not much to be translated as I am giving mostly dimensions. I can try to translate but the words used in my videos can be rather unique and may not be properly translated by Google Translate.
@@pcpairgunschannel 👍👍
Thank you. my regards
Thanks a lot for this educational content, looking towards next video.
👍👍
Then, it would be interesting for you to make a video showing us how each piece works... Your video is very good, works like this only have to add.
I could make an Assambly video once its done, giving a brief idea of how everything works
😮😮😮wowwww just wowww.. bro your talent is so amazing.❤❤❤
I waiting next part bro!!
will take some time :(
As I said in the video the valve releases too little air, so I will make a new valve
Amazing..🎉
Very cool and beautiful.... Is it possible to make a air rifle afc?
I will keep it in my ideas, it's possible I will make it.
Great job bro , but i am still having trouble following exactly how it all really works 🙁🤘🤘
So the valve releases air towards the hammer after being hit, that's why it flings back. If I used an ordinary trygger for this it would be full auto because there's nothing that catches the trygger back, so you can see how this one snaps back up to be used for cocking again, while the trygger is still held down. Thats why it can become semi auto
Thank you very much i got a new ideas from your invention brother. You are extra ordinary mechanical minded. Salute 🙏
Just make a trigger mechanism for 3 modes, single shoot, semi and automatic.... now that's what's giving me a headache hahaha
@@fadelangamingtech9297 needs precision machining so that things stay in place and dont break
I want to make a PCP Airforce Condor with 3 modes single, semi and auto.... I'm confused about the blowback and trigger construction. So far I haven't found a reference
@@fadelangamingtech9297 you need some small parts to switch the trigger from normal and semi auto and a say to block the valve vent hole
Hi bro, can you supply a link for the drill milling machine as you have for the for the metal lathe great job very inspiring
@@gordondunn3694 sorry, i don’t have any global link for it. It is a bernardo KF 20 L milling machine
Hey bro, I’m located in Oz. What would you recommend off in replace of that type of brand of Alibaba express also what was the dimensions of the trigger mechanism? Will buy you a coffee thanks for the quick reply.
@@gordondunn3694 Regarding the trigger, I did not have very specific measurements in mind. I rather had the mechanism alone in mind. This was my first time building such a semi auto trigger, so I am not certain of what dimensions are the best for such a trigger. You can check the caliper measurements I did throughout the video, I showed how much I cut off from the steel bar.
About the question regarding lathes and milling machines outside of Alibaba/AliExpress, I'm a bit unsure but if you are going for machines on the cheaper end, I found this Australian site www.machines4u.com.au/
search for "mini lathe" or "milling machine" and check "price: low to high" because most of the machines on that site are bigger and therefore more expensive machines.
However, since I don't live in Australia I am not the best guy to ask about machining tools and I don't know which sites are the most reliable ones.

Here's an Australian machining channel I've followed. He has videos of his milling machine & lathe, not 100% sure where he got them but they are available in Australia.
Thanks bro. You’re being so more than helpful. One more question. The pistol grip is that offer Crossman also if not or if so what type? I
@@gordondunn3694 sorry I didnt understand, do you want to use A crosman grip for a semi auto
Can you make aluminum or brass barrel with rifling? Nice work by the way. 😀
this design will use steel brrl by crosman. aluminium is too soft, but brass is awesome as it doesn't rust and gets even better with time. However I will make a video of making one using steel, same technique can be used for brass.
@@pcpairgunschannel Thanks for the reply. will be lookin forward to it. 😀
bom trabalho Irmão...
👍
what is the milling machine ?
Bernardo KF 20 L, austrian company
Could it be that you can't just send the parts for the semi-automatic system, disassembled, and I can buy the rest here?
I can't ship any parts, pcp parts are forbidden to ship. I cant even ship toy guns... ridiculous rules
Do you have a project like this pcp that you sell, so I can ask a turner here to do it for me?
Part 3
Upper Receiver block and pellet pusher. How to install?
I will make a video of making them soon, but first it needs valve modifications to function properly
Could you please measure where the kitten box goes?
Sorry, whats the kitten box
Good evening, do you make it to sell and can you send a kit like this to Brazil.
I cant, my country had no couriers that ship air guns
完美❤
Can you make a video and show us how it works? I want to build my own. @pcpairgunschannel
You can understand it by watching the mechanism in the video, but I have a new semi auto project coming where I will show things more clearly.
Bisa pesan tabung dural od 32 buat air arm ga bang
Tidak, maaf
Can you give me a drawing of your trigger design tnx😊
Sorry, I didn't make any drawings. You can see the measurements i made with the caliper in the video and get a rough idea of how to make a drawing of it

你好，我是来自中国的一名PCP爱好者，能卖我一份图纸吗？
我沒有圖紙，抱歉
Pinchis videos tan bonitos y los pasan en puta camara rapida no aprecias nada que no los suban mejor
