Re: Regarding the Legality of Hybrid Spud Guns in the USA

Don't beat yourself up over it. Bad things happen. That's why we try to be careful, but bad things still happen sometimes. We all have our stories and experiences. You shouldn't feel shame for what happened. It was an accident. They happen. Maybe try lead pellets instead? Steel tends to be pretty b...

Small semi automatic hybrid project

Hello !! I was thinking about making a small, handheld semi-automatic. I will try my best to expand this idea Project of a semi-automatic hybrid, topic I planted In another post, but briefly. I have prepared some simple drawings To explain to me on this question. It works like this: 8) The propellan...

Re: Small semi automatic hybrid project

Thinking calm, about the possibility of the "automatic hybrid". The truth is, I only need to speed up the process of this semi-automatic prototype 10 or 15 times, which seems possible, although not very simple. This model, the current one, assuming that the piezoelectric spark plug is replaced by a ...

Re: Small semi automatic hybrid project

I made the video to share here. https://youtu.be/peIh7a-mK80 This is the trigger frequency I am looking for. Actually, speaking of the ignition, a commercial electronic spark plug could be used, fired at the right moment, by this same video mechanism. I used a modified model airplane servo motor and...

Re: Small semi automatic hybrid project

This is the trigger frequency I am looking for. Holy... eres un fenomeno Hector! I really like the electro-mechanical control :D Very promising! Too bad not being able to use a tank with the mixture formed, because in this way it would be firing automatically in two days, but it is not an option du...

Re: Crosman 1330 "Thumper" concept

It is an upgrade that uses a piston valve and not the hammer system, is what I understand. I really like that weapon and I had planned to buy it but they don't exist around here, at least for a long time, when I had the intention of doing so. A question that is interesting, to improve these weapons ...

Re: Electrically driven hammer valve repeater

Nice electromechanical prototype. I did something similar, is what I showed, (thinking of feeding the automatic hybrid), with an advantage and a disadvantage. The advantage is that it is simpler, and the disadvantage is that I cannot exceed 9 or 10 bar, which is the maximum that the solenoid valve s...

Re: Need help

Yes! If the amount of gas exceeds what your syringe can hold, get yourself a bigger one, or make one the size you need, with recycled materials. Example: If in the gun in the video I use 30 bar, the amount of air is 30 times 20 cm3, (which is the volume of my combustion chamber), about 600 cm3 of ai...

Re: Need help

I agree with what they tell you. For your first hybrid barrel a rupture disc system is the simplest thing to do and is VERY EFFECTIVE! :evil: You have to draw a picture of what you have in mind, hybrid barrel size, projectile type, fill pressure and all that. On the other hand, list your specific do...

Re: Need help

Simple. In my case, (this is independent of the mixture retention system that the hybrid has, rupture disc, piston with pilot, o'ring only), for a given combustion chamber volume, I measured with my pressure gauge that with 6 pumps, I have 5 bar. As long as you give 6 pumps you will have 5 bar ... S...

Simple machine gun.

I am interested in the possibility of shooting 6mm plastic pellets without any mechanism. The idea is that the tube that contains the bbs, is hermetically closed At one end, it's gravity feed. When air enters, only one bb propels through the firing barrel. All the Others are driven up into the tube ...

Re: Simple machine gun.

Yes, I have taken into account the point that you make. The charger cap has a rubber so that the bb that can stick there, is not destroyed. I reuse the same bbs many times, so I know they come out intact. Keep in mind that the balls fit quite well in the loading tube. This makes the air contained in...
