Add what was missing to get the valve closed automatically. It works correctly, luckily. The valve closes when you let in compressed air and the pilot depressurizes immediately after firing. The dosing system that I am testing needs to be able to decompress to measure the right amount of butane, it ...

:) Seriously speaking, thank you. There is really no weapon that makes holes at the moment, but I am going to put all this together and another weapon will be born to play a bit. I already had this design of dispenser, but the present work was to adapt it to any piston valve with pilot, in this case...

Yes, the butane tank is always open, and the compressed air tank is always open. Tomorrow I draw a gif so that we can talk and understand each other better.

Válvula colizante.jpg válvula coolizante desarmada.jpg This is the three-way valve, with exhaust, that I use to activate the system, with each shot. It is bistable, but I have added a spring to make it normally closed. I used this one because I had it on hand, but you can use a commercial, three-wa...

The three wise men stopped by my house and gave me a bomb for nationally manufactured pcp weapons. It is a "Spartan 300" from AIRTEC. It's for 300 bar but in this video, they tested it up to 600 bar and it still works fine. It is simple, solid and not very hot ... I don't know how they did that. In ...

I want to show a test of the system for my new hybrid to repeat. I finished building it today, and it works fine. I have to sort a little all the elements that are currently scattered on the work table. I'm working at 5X for testing, and it will be at 8X when the gun is finished. The valve I use is ...

Sistema dosificador para arma híbrida con depósito de aire.png This is the drawing of the system that I am testing in the video. It can be operated with an HPA reservoir or with a manual air pump, with the addition of a valve to depressurize after manually pumping air. It can work with any hybrid p...

I leave the GIF here, to better explain the design. You have to open the image to see it as a GIF. Feel free to ask me what I want, if I can't be clear. Slowly, I will describe each component, those that are commercial and those that I built. 8-) The references are: A- Loading mixture into the combu...

Dosificador volumétrico regulable.png This is the dispenser. It is possible to vary the volume of gas, rotating the knob that has a threaded rod, to move the piston. I use it when I install the system, because being so small the amount of butane that I must measure, a little more or less hose, nece...

Project update. 8-) I built the hybrid's wooden stock, I think it looked nice. I also finished everything about the machine itself. In the photos you can see the parts, the .25 caliber barrel, the bolt system, the piston valve with automatic pilot opening and closing of the pilot, which I described ...

Time to admit that I've harvested enough Crosman donors for all the projects I have in mind and I ought to get started on one of them

Oh yeah! many weapons before everything is over, that's the slogan. What is this project about? I am curious...

In my country, these hobby weapons are considered directly as firearms. I investigated and asked acquaintances who work in the regulation of weapons, and they tell me that I cannot carry them, nor shoot outside an officially authorized shooting range and with a psychophysical examination ... Stupid,...

What is this project about? I am curious... 8-) I like the Crosman style grip, very convenient and I have used it before on the "Caselboy" . There are several pneumatic projects I have on my list for which this collection is intended to provide parts, along with an assortment of rifled barrels and ...

Bounce a short distance, against the concrete wall, about 50 cm. I was about to point the gun at the target, a cardboard box with a lot of newspaper inside, and I accidentally pressed the spark gap before aiming exactly at the target, when the wall was just ahead ... Calaculo, if you shoot me at 10 ...

Damn, that was lucky. I had a similar experience many years ago with an 8mm ball bearing that bounced back on a steel plate - though I was not struck, it did make a nice clean hole in what was then my bedroom window: https://www.spudfiles.com/download/file.php?id=4643&mode=view A foot or so to the ...
