wood, just a little bit, in the grip where the piezoelectric goes because I thought it was nice that everything is in sight.
It is the simplest, easiest and fastest gas dosing system to build,
and it does not fail.
The weapon is an autonomous hybrid that shoots steel balls of 1/4 ", to 8X.
The air pump has been optimized to achieve that pressure, without much force,
with 7 pumps. The tube of the air pump has a diameter of 27 mm. The two valves
of the air pump are commercial, and support, according to the manufacturer, up to 10 bar.
The two valves of the combustion chamber are manufactured by me, and
They work very well for combustion pressures.
The firing pipe is smooth bore, built by me. It has a thin steel tube outside,
with polyester resin inside, to give the caliber of 6.35 mm.
It is light, only 1.9 kg.
I have incorporated a very effective silencer, because the noise no longer bothers me.
It is built with an aluminum tube, i have glass wool inside,
to decrease the acoustic energy of the gases.
The fuel gas tank is a simple and common small aerosol, and I use the valve
that comes incorporated from the factory, to inject gas into the dispenser.
The gas dispenser is only a plastic tube of 10 cm3 capacity, which is the
that burns this weapon. It has no piston, and is not subjected to any pressure. The gas when entering
by "A", it dislodges the air by "B", and the gas that remains inside, is then sucked
by the suction valve of the air pump, "C", and introduced into the combustion chamber.
Simple and without failures, for this type of volumetric meter for small arms.
The combustion chamber has a single hard spring, which is responsible for retaining the pressure
of mixing, and leaving the camera with zero volume after shooting, to clean it completely.
I'm using 8X, but the system can hold mix up to 12X without opening the hole
gas exhauster. The problem is that it is not safe to reach so much, because the thickness of the steel tube
recycled from a shock absorber that I am using, only 0.8 mm. I have steel tubes with burnished
inside, but this one in the Mr. of the winch, delayed there.
The red color command seen in the fifth photo is the valve to depressurise the combustion chamber after the shot. Frequently there is some burnt gas inside and it is necessary to press to completely clean the combustion chamber of burnt gases.
When I make the shooting test video, I'll cast it here. This is a totally homemade weapon,
I mean manufactured with few common things, and without any lathe, or welding. I have already fired some
80 times, and everything is still in place. We'll see how it works with more shots.
Definitely not an option for me, and I hope for no one.
Those that I use in the present are common, those of black color. I can replace them if they deteriorate but the longer they last, the better.
This is, I hope it is really like that, the solution for all this.
