Although it was not the on-board inverter that he found awkwardly, as he expected, after installing the air nail gun on the air pump, it did play its due role.

It's just that the woodworking air pump has a pressure tank, which can store a part of the compressed air, and when the air pressure is insufficient, it can be turned on, while the vehicle-mounted air pump has no such function at all, and it must be turned on all the time when it is used.

However, this little flaw does not affect the use at all, but it is a pity that the carpentry chainsaw is useless after being connected to the battery, which makes He Jun very disappointed.

But no one can do anything if you can't find an inverter, and the air nail gun can be used, which is much better than guarding a bunch of tools, but you can't use it at all.

From this day on, He Jun and the gangster trio devoted themselves to the experiment of making crossbows in addition to eating and sleeping.

With the decoration materials prepared in the 901 home, the crossbow body no longer uses smashed chairs, but uses ready-made wooden squares.

There was no suitable material for making crossbow arms, so He Jun found Uncle Liu and dismantled his leather band chair.

If you don't have the ability to cut out a straight arrow path on the wooden square, you will nail two straight thin planks to the wooden square, and use the gap in the middle as the arrow path.

If there is no suitable arrow shaft, several chopsticks are connected together with scotch tape from head to end.

If there is no arrow, sharpen the tip of the chopsticks and burn them with fire, or tie a steel nail to the head of the chopsticks; Wangshan is two pieces of wood nailed to the tail of the crossbow body with an air nail gun.

The crosshair was a nail head nailed to the body of the crossbow, and the arrow feather simply broke a thick triangular piece of paper between the chopsticks.

All in all, on the premise of ensuring that the arrow can be shot smoothly, it can be replaced if it can be topped, and whether the final product can be called a crossbow is not in the consideration of He Jun and others at all.

The four of them experienced a dozen failures, and it took two full days to figure out the first crossbow that could be fired, and another day to improve it as best they could.

The improvement is mainly in two aspects, one is to test the optimal ratio between the length of the rubber band and the length of the crossbow body, so as to avoid the phenomenon of weak firing force or damage to the rubber band; The second is to nail a palm-length horizontal wooden strip on the crossbow head, which looks a bit like a crossbow arm, but in fact it is just a substitute for the pedal, in order to step on it with the foot to facilitate the winding.

It took three and a half days to make a nearly practical crossbow, and the final product did not look like a crossbow at all, but like a large slingshot mounted on the crossbow.

Anyway, the thing was made, and several people immediately ran to the rooftop to test the crossbow, and in order to accurately determine the range of the crossbow, Douzi also found a dartboard from home as a target.

He Jun was the candidate to test the crossbow, stepped on the crossbar on the crossbow head, tightened the loose leather band, and hung it into the groove of the crossbow tail without much cost.

Awkwardly hurriedly handed over an arrow made of two chopsticks, He Jun picked up the results of three days of hard work, pressed the arrow on the arrow path with a lot of poor specifications, thought about the essentials of shooting during military training in college, and aimed at the target more than ten meters away.

There is no crossbow machine under the crossbow, you must use your fingers to press down the small wooden strip above the crossbow body, you can't aim like a gun at all, He Jun tried a few postures, and felt that the posture of using his left hand to support the front of the crossbow, his right hand to support the tail of the crossbow, and the index finger to press the hair is the most appropriate.

It was taken into account that the finger press might block the lookout, so the lookout on the crossbow was not in the center, but to the left.

This method was not devised by any of the four people, but He Jun imitated the ruler position of the Czech light machine gun.

When He Jun said the Czech-style machine gun, none of the gangster trio knew what it was, until he explained that it was the kind of machine gun with a magazine on it in the Anti-Japanese War movies and television, and the gangster trio suddenly realized it together.

The range of the anti-work DIY crossbow is definitely not far, even if it is equipped with a high-powered scope for a large-caliber sniper rifle, it can't shoot that far, and a little deviation has no effect.

He Jun recalled the shooting essentials he had learned back then, squinted his left eye to slow down his breathing, and pressed his finger downward, but he couldn't pop the crossbow string out of the groove!

The simple crossbow machine solution provided by Uncle Liu only solves the problem of having and not having it, and it is completely impossible to say what the ergonomics are, but then again, as long as the crossbow machine is a little more complicated, they can't make it with simple tools.

What horse wears what saddle, what foot wears what boots.

He Jun rolled his eyes helplessly, let go of the rough crossbow and exhaled, and re-aimed at the target according to the clear essentials of the blurred crosshair.

This time, he was well prepared, and pressed the "crossbow machine" of the rocker hard, and the rubber band popped out of the groove with a slight sound, and successfully launched the arrow made of two chopsticks.

With a soft sound, the arrow hit the lower left edge of the target and bounced out again, at most it looked like nine rings and ten rings.

The awkward one didn't hold back, and laughed out; Douzi wanted to laugh but was embarrassed, and his expression was very strange; Only Ryoko was expressionless, and there was no joke at all.

He Jun grinned, not caring at all about the awkwardness and the performance of the beans.

It was so close and so far off, it was definitely not that he couldn't aim accurately, but that the simple crosshair on the crossbow was too bad.

He picked up his axe and lightly smashed it on the nail that served as a crosshair: "Beans, give me another arrow, a chopstick." ”

No one knows whether an arrow made from one chopstick will suffice, or if two chopsticks must be connected before they can be used, so there are some arrows for both types.

If you must use a long arrow, attach a chopstick to the short arrow, and if not, remove the scotch tape.

Beanzi agreed, and quickly handed the arrow over.

He Jun tried again, and this time the arrow was shot on the fourth ring, the height was uneven with the fifteenth, and it was basically on the same vertical line as the first arrow.

The crosshair still needs to be adjusted again, but the height is just right, just a little to the left, and then using the axe to move the nail will definitely affect the height of the crosshair, so He Jun took out his dagger this time and cut off the right side of the gap in the wooden lookout mountain behind the crossbow a little.

At this time, Awkward had already picked up two arrows, looked at the nails that had almost fallen off the arrows, and said: "Both arrows have pierced the target, and the marks left on the wall are similar, I think that the length has no effect on the power." ”

"Then I'll use a chopstick." He Jun tightened the rubber band again.

Douzi said slanderously: "Brother He, let me try it too!" ”

"And me, and me!" Awkward and can't wait to say.

Although Ryoko didn't speak, the desire in his eyes couldn't be stopped, and he couldn't pull it out if he stuck to the crossbow!

He Jun said patiently: "Take your time and make peace, everyone has a chance, but you must first let me adjust the crosshairs." ”
