Do you work with tree, drywall or metal - everywhere you need a construction tape measure. Everyone has this measuring tool, but not everyone knows what it is capable of. Let's fill this gap - reveals the secrets of the measuring tape.
Everyone knows that a tape measure is needed for measuring and marking, what else, it would seem? The design of this tool is simple: a body, a pair of clamps, a measuring tape and a hook on the last one. Not everything is so simple and obvious.

Secret #1
Let's start with the hook. Everyone who encounters a tape measure for the first time noticed that the hook, the one at the end of the measuring tape, is poorly fixed, that it dangles. And he probably thought it was a marriage. However, it is not.
This backlash is not accidental, and is made on purpose - it is equal to the thickness of the metal from which it is made. This eliminates the appearance of a measurement error.
When measuring from the object, the hook moves to the measuring tape and becomes the zero point of measurement.
If the measurement is made with the capture of the object, then the hook is displaced by the thickness of the material from which it is made, and this value is thereby compensated.

Secret #2
Having bought a tape measure, few people study the inscriptions on its case, but in vain. On most specimens, there is some numerical value (the length of the tape measure body), which helps to measure the distance between two surfaces.
To do this, you need to put it against the wall, take a measurement and add to the last numerical value indicated on the roulette body.

Secret #3
There are cases when the length of the tape measure is not enough, then they resort to this method. Measurements are made in opposite directions - a point is selected where the length of the measuring tape is enough in both directions, and these two quantities are measured, which are then added.
For accuracy and convenience of measurement, masking tape is glued in that place, and an intermediate mark is marked on it (preferably in the form of a checkmark). In this case, you will be sure that the calculation will be accurate to 1 mm.

Secret #4
Using a tape measure, you can quickly and accurately divide the distance in half. The measuring tape is folded in half, the hook (beginning) is aligned with the value of the divisible length, and the upper point on the fold of the tape will correspond to the desired value.

Secret #5
There is a technical hole on the hook of the roulette. It is designed to measure large values - made specifically to fix the beginning of measurements on the head of a nail or self-tapping screw.The measurement error in this way is small - the center of the screw head almost coincides with the zero point, the error can be 1-2 mm, which is easy to take into account in the calculations.
Using this hole, you can not only measure large lengths, but also draw circles.

Secret #6
The next thing you can do with a roulette wheel is refine it. Attachment for a pencil is added to the case.
By inserting a pencil, we get a convenient device for applying marking marks.
Also, this device can be used as a thickness gauge, i.e. draw parallel lines at any distance.
And if you use a technical hole and a screw, then a full-fledged compass will come out.

Secret #7
Have you used a tape measure as a notebook yet? And in vain, it is very convenient. You just need to stick a piece of masking tape on the body.
Don't have duct tape handy? You can also write on the body — Pencil marks are easy to erase later.

Secret #8
If the work is done with soft surfaces: wood, GVL or GKL, then you can not use a pencil at all.
On the hook of the roulette with a file, we make notches and the scriber is ready.

Secret #9
And finally, bonus secret #10 - division of a segment of any length into any number of equal parts.
For example, you need to dissolve a board 27 cm wide into four equal parts. Nothing needs to be calculated. Any numerical value is chosen that is a multiple of the number of parts needed, i.e. four, - the main thing is that it be greater than the width of the board being unraveled - say, 40.
We apply the measuring tape to the board so that the zero and 40 cm marks are aligned with the board. We make marks according to the tape measure every 10 cm, and we get the desired marks without any calculations.
