- Tactical Pen | Air Operated For Self-Defense
To pressurize the tube, a high pressure pump or bicycle pump is attached to the car tyre valve. This pushes the piston up against the barrel (piston function is to seal the barrel at the time of air filling), preventing any of the air from escaping. The piston doesn’t make a perfect seal agaist brass tube (piston can easily slide forward and backwards), so air leaks around it and pressurizes the main brass tube. The car tyre valve also prevents the air from leaking out of the pen body. When the car tyre valve stem is pressed, the air escapes, the sudden pressure imbalance causes the piston to shoot backwards(at the time of filling air the piston will be pressed against the barrel), opening up a path for the air to escape through the barrel. This escaping air propels the projectile.

Unfortunately, when you search for "tactical pen diy", instead of something as good as this, you're shown garbage where people are glueing stones and other pieces onto pens. This is actually good quality stuff
Man you deserve millions of subscribers
You are doing really great job
It's all about talent
Thanks a lot
You are amazing as always.
This is Soooo Perfect
This is awesome dude. Damn i love it
I used to build this long time ago. I never know that soldered wire could withstand such pressure! I used epoxy
Is epoxy also that tough ?
Thank for sharing your idea, i'll try to make my own as did,.
OMG nice bro
Incredible my friend. I'd like to see other ways this could be used.

How many psi can this thing withstand?
Todos los que publicas está muy bueno,si sería tan amable de mandarme los plano y medida del pcp m4
Can 2 tyre valves be used, one as entry to charge the cylinder and the other as an exit (propellant) near hammer to shoot projectiles out? (To avoid using all the air at one shot) Or a tyre valve is not good to pump up the pressure in crown fast enough? ❤
By the way you're great 👍👍

I got it from a hardware shop
the mechanism is confusing
牛逼
А как она работает я чë тот не понял🤔
Ствол находится в резервуаре.
в нем же, за стволом, вставлен поршень(между стенками и поршнем есть небольшой зазор)
За поршнем герметично вставлен клапан, через который в ручку заканчивается воздух
Через зазор между стенками и поршнем воздух попадает в основную камеру(вокруг ствола)
При нажатии на клапан, давление за поршнем понижается, из-за этого он отходит назад. В ствол выходит основной объем воздуха, выталкивая снаряд.
Не думаю, что от моего объяснения стало понятнее ;)
@@ChebuplZZa спасибо, дошло))
