What every man should know about working with a file. The trick of the masters

We master. Almost everything is ready. It remains a little bit to modify the file. Well, you know what I mean 😜 And this “enemy” tool spoils everything. They wanted to slightly increase the diameter, but got an oval hole instead of a round one. To make matters worse, the contour that had been perfectly flat a minute ago looked like a bumpy road.

I will share one method of working with a file. It is extremely simple. But the holes remain perfectly round. Recently I had to enlarge the mounting holes of decorative cups. Here is the result.

When metalworking, the file is always smaller than the hole. It doesn't matter if it is round or semicircular. It turns out that only the tip of the cutting edge removes the material. As a result, we make a series of grooves, trying to smooth them out in a lateral motion. Not everyone knows that the working width can be significantly increased.

Expanding the attack area is extremely simple - we set the file at an angle. As a result, it touches the workpiece along the entire edge width. This, of course, does not mean that the circle will turn out by itself. But it becomes much easier to machine the hole evenly. We go several times along the entire length and get an even circle.

I had to modify the reflectors not from a good life. He told about the pitfalls that can be encountered when installing a heated towel rail in a separate article. Thanks for reading. If the material was helpful, the best thanks - subscription and like 👍.
