I check the diagonal roof. As I have tried to do it as accurately as possible, and what eventually happened?

Some operations require the availability of good tools that are only professionals. And if you samostroyschik, and all that you do not need?

Last ❗ control point before the installation of metal. And that depends on how much I'll tinker with it, during installation.

During the construction of his house, I have had to make such measurements.

For example, I checked the geometry of its foundation, you can read in this article: "The geometry of my foundation. Is it possible to enter the tolerances without special equipment? "

And making these measurements, I always visited doubt. More specifically, only one:

On exactly how much everything can be measured by one, and by conventional means, or rather a tape measure?

✅ Of course, I understand that in most cases, the errors plus or minus a centimeter, no special role to play. But what becomes real value when imposed errors in performing the work, and when it is checking?

And here once again, with all the doubts in my head, I began to check. This time it comes to roofing.

What is it for?

Metal, which I will cover the roof, is a material which is relatively simple to operate. But he does not tolerate mistakes.

Do not get correct mounting material for all the irregularities and shortcomings base. And if the coating metal tile must, ultimately, be of a perfect rectangle, the same should be the base, ie the contour lathing.

❗ And the main parameters to be checked are the part of the roof slope, and its diagonals.

And as I tried to make it as accurate as possible.

🔹Otrezaem too much in place.

In one of his articles ("Under the metal crate. Valuable tips that I tried on myself. ") I wrote that I crate crepe whole boards, no measuring out the exact size.

Here at this stage I do bring the most benefit.

In fact, I had not checked the diagonal, and mark the crate so as to obtain the desired size. And then saw off the excess.

The little things will not go, not great it is a science. Hto tell about the main point.

In all of these measurements, it is necessary to control not only the equality of the diagonals, which is spoken by all.

✅It is necessary to monitor and size of the partiesWhich should also be the same. Then get a rectangle and not a trapezoid.

🔹No here emerges the question of measuring instruments.

Of course maximum precision will give a modern, electronic devices, such as laser roulette.

But I have always been convinced that such tools should be in the arsenal of professionals who constantly use it. And this samostroyschiku as I spent on it, for once, does not make sense (though, and I'm on the same construction site, something often need to become such a device).

Be that as it may, the only tape was in the hands, and the band (no metal).

But this helped me a crate.

Of course to make changes such tape in the air - this is a bad idea. Too much is uncertainty due to belt stretching.

But when she lies on the plane of the crates can expect a more or less normal measurement.

Eventually, indications on the rouletteThe parties were equal, and diagonal, too ...

But is it really??? Of course errors will, there is no doubt. But it is not critical, lists only laying of metal. But this already in the following articles.
