In this article, Andrey Vinnichuk will return to the topic of a blacksmith tool.
Let's see how to make firmware.
This tool is designed for flashing holes of different diameters in metal.
The tool is very necessary in the forge, and the author hopes that it will be useful to you in your business.
The material that the author will use to make this tool. Andrew will use a car spring.
Very good, strong steel, quite suitable for the manufacture of this type of tool.
To begin with, the author will heat the spring and align it.
Sharpens one of the endings of a future part.
Further it will already form a tool.
Smoothes out all faces so that the firmware is round.
This is how it heats up further, performs heat treatment. The author will harden in oil.
Now we’ll heat up, let's see.
Quenching and tempering will be done in one heat.
Hardening tool. The tempering temperature is determined by the colors of the discoloration.
Since the tool will work hot, vacation is carried out in this case to purple.
Here, we are waiting for the purple to drop to the edge.
Periodically clean off the scale with sandpaper.
As soon as it comes, we immediately cool the metal.
There is still a little left if it is necessary to heat, we can also heat from the shank, which will accelerate the process of tempering the metal.
We wait until the tool cools down.
Let's try it in action.
So our firmware is ready.
You saw how it can be done, how to harden and temper.
It is convenient to hold in your hands. You can also grab it under the ticks.
Now we will check it in business. Preheat the workpiece.
Now we break through from the reverse side.
With it, we can punch holes of both small diameter and large.
Andrei will not punch anymore. This is how it is all done.
