Re: High pressure air pump

Do not tempt me ... :evil: I am in a super urban environment full of allergic to explosions, my possibilities of making noises are very limited. I made a semi-portable 800 psi cylinder with common commercial elements, and I didn't have to reach that pressure to fill it, but now I do. What I would li...

Re: Hybrid repeat system

That is next level stuff there. I am still trying to wrap my head around this. Clearly it works. Maybe once I have my system complete I will try my hand at autonomous function. Thanks for sharing this! I am willing to help in what you need, if you ever want to try. You can't really find a simpler w...

High pressure air pump

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 ...

Re: Hybrid repeat system

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...

Re: Hybrid repeat system

This is the valve that lets the butane pass into the dispenser when it is activated by compressed air. There are commercial ones, but I prefer to make it myself, because they are very cheap and I can repair them. It uses a car or motorcycle tire valve, which is what the small piston, (6mm), depresse...

Re: Hybrid repeat system

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...

Re: Hybrid repeat system

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...

Re: Hybrid repeat system

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.

Re: Hybrid repeat system

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...

Re: Hybrid repeat system

:) 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...

Hybrid repeat system

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 ...

Re: I'm back!

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 ...

Re: I'm back!

Yes, using a high pressure tank is more comfortable and faster than pumping, but in my city these things are very expensive. Likewise, I have a co2 reservoir, which I can fill with air up to 900 psi, and I use a reconditioned pressure regulator, which is from an oxygen tube. It admits up to 200 bar ...

Re: I'm back!

A photograph of how it was. I am building a mechanism so that it closes automatically. The small piston with two o'rings and the hole in the center is for decompressing. It is fiberglass because it only supports 6 or 7X pressure. The hard part is the one that seals the chamber. I leave here in this ...
