Re: Automatic semi - full pneumatic system

I'm impressed with what these soft air balls can do .... 850 fps !! A significant amount of pressure. Very didactic animations. Truthfully, I've never had one of these to pry. A charm of construction and precision, although these designs, would be impossible to build by me. That is why I have to des...

Re: Automatic semi - full pneumatic system

Great shots!!!! :bounce: Does it work with air? Or co2? In the case of my experiment, there is no problem with reducing the number of shots per second. The system has to regulate this. Actually debría to use air soft ammunition of 6mm, should work equally, but the problem is that I do not like hahah...

Re: [WIP] Triggered Ball Valve Musket

Good job. It looks old enough that is what I like about the appearance, and will surely fire with enough energy, when the weapon is finished.
On the other hand, the small manometers of which you have this super good! I pay to see his gun firing. regards

Re: Automatic semi - full pneumatic system

Another fantastic project, bravo! That rate of fire control is genius. The fact that it's all achieved with home made parts and basic tooling makes such a sophisticated project all the more impressive, well done! Thank you Jack ! I forgot to mention that the tube where the ammunition lodges, enter ...

Automatic semi - full pneumatic system

V4CcwST.jpeg 6C8kvWU.jpeg Hello everyone ! I have built this basic model of a system for a future weapon. It works at this present time, with compressed air at 4 bar, but it would be possible to feed a definitive version with CO2. It is not really a weapon, just the test system, but functional. The...

Re: BFG #7

A weapon's beauty! Does it work with Co2? I have in mind to make something similar semi-self. I have a "mockup" although the system I'm using is different. Great job, congratulations !! :bounce:

Re: Small Hybrid.

Ok. I will try with photo paper, for rupture disc and to use the simulator that I already recommended to use previously. Greetings and thanks.

Dico ruptura cartucho.jpeg Wow, much more ingenious than I initially understood. I hadn't realized you were using burst disks on you "cartridges"! Once again, excellent work! Hello ! Thanks again! Yes it is. I thought I had mentioned it sometime. I'm using thin aluminum foil as a rupture disk, the ...

Re: Small Hybrid.

Looks nice. Do do you have any details on how the pump connects to the chamber, like is there an isolation valve (besides the check valve in the pump) between them? You posted the other pictures again but none of the diagrams. :D PD: Saludos desde la isla de plátanos y béisbol. When I go home, afte...

Re: Small Hybrid.

Thank you very much. I am very amused to build and shoot these things. I have devised, for the next prototype 2, several improvements. The future weapon will have a magazine and will expel used cartridges, and the gas charge is fully automatic. I will publish the diagrams here to give you their opin...

Re: Small Hybrid.

I uploaded the videos of the small hybrid rifle. I recorded them in the very small space I had available at home. I had to encourage to go to the store to shop for my people :shock: and "nothing has happened here" :roll: Greetings [youtube]https://youtu.be/Bk-cSgIoXHk[/youtube] [youtube]https://yout...
