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.

[@pcpairgunschannel]

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

[@charlessilva6365]

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.

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.

..good design on the trigger.. nice work!

[@pcpairgunschannel]

Thanks! Hopefully I will also increase the air consumption with valve mods.

[@benoitdudzik8010]

super nice job as usual !! never stop

[@baosaka6518]

You have done a good job, I want to get one like this, but no tools.

Your a brave man using that angle grinder like that

[@zartansniper5529]

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?

[@pcpairgunschannel]

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

I waiting next part bro!!

[@pcpairgunschannel]

will take some time :( As I said in the video the valve releases too little air, so I will make a new valve

[@Bangsoljirak]

Amazing..🎉

Very cool and beautiful.... Is it possible to make a air rifle afc?

[@pcpairgunschannel]

I will keep it in my ideas, it's possible I will make it.

[@gordondunn3694]

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

[@pcpairgunschannel]

@@gordondunn3694 sorry, i don’t have any global link for it. It is a bernardo KF 20 L milling machine

[@gordondunn3694]

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.

[@pcpairgunschannel]

@@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. www.youtube.com/@artisanmakes 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.

[@gordondunn3694]

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

[@pcpairgunschannel]

@@gordondunn3694 sorry I didnt understand, do you want to use A crosman grip for a semi auto

[@jimsun2486]

Can you make aluminum or brass barrel with rifling? Nice work by the way. 😀

[@pcpairgunschannel]

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.

[@jimsun2486]

[@karlalton3170]

Great job bro , but i am still having trouble following exactly how it all really works 🙁🤘🤘

[@pcpairgunschannel]

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

[@steevevender606]

Thank you very much i got a new ideas from your invention brother. You are extra ordinary mechanical minded. Salute 🙏

[@cintaamirasyifa221]

How to apply it to bullet plunger? Please 🙏

[@pcpairgunschannel]

do you mean the receiver? The thing which holds the barrel, bolt etc? I will make a video on that way later. I have another semi auto project

[@fadelangamingtech9297]

[@pcpairgunschannel]

@@fadelangamingtech9297 you need some small parts to switch the trigger from normal and semi auto and a say to block the valve vent hole

Part 3 Upper Receiver block and pellet pusher. How to install?

[@pcpairgunschannel]

I will make a video of making them soon, but first it needs valve modifications to function properly

[@edgardutradefaria3775]

Could it be that you can't just send the parts for the semi-automatic system, disassembled, and I can buy the rest here?

[@pcpairgunschannel]

I can't ship any parts, pcp parts are forbidden to ship. I cant even ship toy guns... ridiculous rules

[@edgardutradefaria3775]

Do you have a project like this pcp that you sell, so I can ask a turner here to do it for me?

Can you give me a drawing of your trigger design tnx😊

[@pcpairgunschannel]

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

[@BernyAV]

Please sir, don't wear those gloves. Those could get caught on the lathe. I use Nitrile gloves when turning brass. Nitrile gives ample protection from the brass swarf embedding into your skin, but would easily tear when caught in the lathe.

[@pcpairgunschannel]

Yeah, I don't wear gloves while operating a lathe anymore.

[@BernyAV]

@@pcpairgunschannel That's good to hear sir. Every time I saw you touching the material while the it's still turning gave me the shivers. I made the same mistake early on my hobby machining. Got may gloved hand caught while putting a polish the Aluminum I just turned. Luckily, I was quick enough to hit the emergency button and stop the chuck with my other hand before my caught arm could get pulled off from the shoulder.
