The equipment is not easy to use. You need to constantly adjust the cutter head instead of adjusting the steel bar. This is also something that can't be helped.
This is more troublesome and requires experience, but Qin Jun has experience and is not afraid of trouble.
Next he needs a smaller spring, which requires more subtle operations.
Fortunately, he had a good feel and rich experience, and he quickly produced two qualified small springs.
After testing it, it turned out that his operation was second to none. The main reason was that the quality of the steel was too good.
Otherwise, with his crude equipment, he would never be able to produce a very good spring.
I put the two steel pipes together again and tested it, and it was just right.
The next step was the technical work. Qin Jun directly took out a set of lead-acid batteries from a small wooden box on the bedside.
Naturally, this thing was borrowed from Qin Xia, otherwise where would he find the battery?
Since I borrowed the battery pack, naturally there will be no shortage of other things.
For example, wires, pliers and a few 2.5 welding rods.
Connect the pliers to the wire, then connect it to the battery, and connect the other wire to an iron piece, so that the positive and negative poles are complete.
Place the iron piece on the steel pipe, clamp the welding rod with pliers, and then a simple welding machine is completed.
The welding machine is actually very simple.
It uses a large current short-circuited the positive and negative poles to form a high-temperature arc at the contact point to melt the solder on the welding rod and the material to be welded.
Finally, the materials to be welded are fused to achieve the purpose of welding.
Welding machines are generally divided into two types according to the type of output power supply, one is AC welding machine and the other is DC welding machine.
Both types of welding machines use the principle of short-circuit high current to melt the metal at the contact point.
When the positive and negative poles are short-circuited, the large current is used to form an arc to melt the solder on the welding rod and combine them at the atomic level.
Now the two power cords are connected to the positive and negative poles of the battery. As long as the welding rod contacts the steel pipe, a short circuit will be formed.
Now look at the inside of the battery to see if the stored current is sufficient.
If it is not enough to melt the 2.5 welding rod smoothly, it cannot be used.
If it is enough, it will naturally melt the welding rod and steel pipe, so that you can weld anything.
Qin Jun took out a small iron piece and attached it to the steel pipe.
Then use pliers to clamp the welding rod at the junction of the steel pipe and the iron sheet.
Sparks flew and it felt like the welding rod in his hand was sticking to the steel pipe.
This is a good sign, indicating that the welding rod has melted.
Determined to be usable, Qin Jun directly came to use a fish scale weld this time.
The welding rod quickly and evenly circled the steel pipe and iron piece, making a quick circle.
At this time, the iron piece is welded to the steel pipe.
After the welding was completed, I tried it and it felt pretty solid.
After knocking carefully, I felt that there were no welds and the welding was very strong.
However, it's not over yet.
Qin Jun took out another slightly thicker and slightly longer steel pipe and welded two small ears on it.
Then replace the drill bit to drill holes in it. After completion, drill holes in the iron sheet that has just been welded to the thin steel pipe.
There are four holes for hanging two springs.
At this time, the main body of what he wanted to do was almost completed.
Take off the drill bit and replace it with a cutting piece that has a diameter of more than fifteen centimeters.
Needless to say, this thing is cast again.
But it was then forged, filed, and serrated.
The circular saw blade produced in this way can only rely on the strength of the steel itself to cut other metals.
He made a lot of blades, saw blades and other tools like this, bits and pieces, and they were all untested.
This time I made a small gadget, and I just wanted to test it out.
For example, the previous large and small drill bits can easily deal with some ordinary steel.
The high-carbon steel saw blade rotates quickly, and the thin saw teeth quickly cut the steel pipe.
This kind of steel pipe is just low carbon steel, which is more flexible but not hard enough.
So even with a foot-operated transmission system, it can cut long sparks smoothly.
Qin Jun had better clamp the steel pipe on another clamp, otherwise, he would really not be able to hold on to the power.
Soon, a small crack appeared on the steel pipe.
By this time, the main body of the small toy he made, with a large tube inside a small tube, was completed.
With two springs pulling it, the thin steel tube inside can easily bounce back as long as it is pulled out.
"We don't need the wheels, just weld a gun mount directly."
Using a simple welding gun again, after a few swings, a few thin steel bars were welded to the barrel.
Yes, the Qin army made this the simplest artillery.
Of course, the shots were definitely not cannonballs, but firecrackers.
He also learned this stuff on the Douyin platform.
Just put the two barrels together, pull out the inner barrel, and put in a small firecracker.
The gap in the thin steel pipe allows the firecracker fuse to be exposed, making it easy to ignite.
After being ignited, the firecracker explodes within the barrel, and then the remains are ejected from the muzzle.
This thing is just for fooling children, it is considered a small toy.
However, this thing should be able to capture the public's attention in this era.
Part of the reason for making this thing must be to make the two nephews happy.
The other is to experiment and hone in on the homemade tools in your hands.
“My hands haven’t even grown yet, but I’m still so powerful!”
Qin Jun found out the little red whip bought by his second brother and tried it and found it ok.
A small red whip two to three centimeters long with a hundred rings on it has been very popular in recent years.
This thing is now only 20 cents, or 30 cents a piece, but that’s how much money it is anyway.
I definitely don’t buy them in normal times. Only during the Chinese New Year will parents buy one or two hangings for their children.
After all, it's the Chinese New Year, so let's celebrate.
After testing it, it seems to be the case.
Just light the little red whip and push into the barrel.
As the firecrackers exploded, there was only a bang, and something sprayed out from the barrel. It really looked like a cannon.
After firing a few shots, I checked the barrel, the spring and the small iron pieces welded on. There were no problems, and there was no sign of desoldering.
Qin Jun directly placed the cannon on the windowsill.
His two nephews and a niece will not go home until the Chinese New Year is approaching, and this thing will be useful at that time.
However, only one small cannon is not enough, there must be at least three.
Anyway, the materials are ready-made, and Qin Jun doesn't mind making a few more, after all, it can be regarded as a running-in tool.
Of course, the reason why Qin Jun prepared so many tools was not to make this small cannon, but to make a more refined pistol.
The reason why he wanted to make a pistol was because Qin Jun wanted to go out, and to a far distance.
It’s not too far, so I’ll go to the county seat.
However, Qin Jun wanted to visit the largest black market in the county.
After all, who would be reborn in this era and not want to visit the black market?
When Qin Jun read novels in his previous life, they usually wrote about the pigeon market in the city.
In principle, it is not a black market, not even a real ghost market.
The real black market is really black!
Anyway, after returning to 1979, Qin Jun never thought of visiting the black market around the commune.
The current black market trades either grain or other precious metals and other contraband.
This is absolutely illegal, and it is a behavior that the country focuses on cracking down on. There is absolutely no way to turn a blind eye.
In fact, attacks by violent agencies are not the most important threat.
The biggest threat when going to the black market is gangsters and gangsters.
During this period, or in the next ten or twenty years, there were whole villages who were thieves, and there were whole villages who participated in robberies.
Otherwise, why would there be a unique term for this period, "Fare Road Fighter"!
Anyway, traveling far away is not easy now, it can even be said to be dangerous.
Of course, if the poor bones are clear, there is not much danger.
However, as long as you enter and exit the black market, others will definitely know that you either have money or something.
If you don’t rob such a fat sheep, who can?
If Qin Jun went to the black market alone, he would naturally be unwilling to do so.
However, if the second brother Qin Feng and Zhao Erwa are added, Qin Jun will not have any burden.
However, even if he has bodyguards, he still needs to prepare something of his own.
For example, the famous Continental Luzi was imitated because he got a lot of 9x20mm pistol bullets from Qin Zheng.
The number is quite large, hundreds of rounds.
This stuff has been piled up in the warehouse for who knows how many years.
I don’t even know why there are such bullets in their village.
Because there is no pistol at all in the village's gun library, let alone the Horse Brand Luzi.
