How to wield roulette with the skill of a professional

When repairing or manufacturing any crafts, the master must measure everything several times. For this, measuring roulette is ideal. It does not take up much space in your pocket, and if necessary, you can measure values up to 5 m with roulette. But not everyone knows that metal roulette actually has several functions.

So that you can get the most out of using a measuring instrument, we'll tell you, How to use roulette And what are its advantages over the usual ruler.



The advantage of roulette is that it can measure an object without additional help. To do this, there is a special hook on roulette, which is fixed on the edge of the wall, table and so on.
If you notice that the hook is mobile, it does not mean that the roulette is defective. This nuance manufacturers thought out specifically to ensure maximum accuracy of measurement.

When you fix the roulette on an object, the hook shifts and the zero point coincides with the edge of the object being measured. Therefore, always make sure that the hook is exactly located when moving.



When measuring with roulette, you can encounter the fact that the edge of the object will be located between the divisions. Therefore, it is always better to round the resulting value to a larger size. In case of an error, you can always cut the object again. But to spend materials for the manufacture of virtually the same part, but a couple of millimeters more, will be a waste of money and time.



For measurements in openings, use the roulette body instead of bending the metal tape. For example, if you want to measure the inner width of a bookshelf, place the roulette on one side of the object, pull the hook and measure the width of the shelf. After removing the reading from the tape, add to them the length of the roulette body (usually the size is indicated on the back of the roulette), and you will get the exact size of the width of the shelf. The advantage of this method is that the tape does not wear out prematurely and will be in good condition longer.



If you always wanted to know why the roulette line is concave inward, here is the answer. This is necessary to increase when using measuring roulette its rigidity. This ensures accurate measurements.



Why on the edge of the roulette hook there are dents for a reason. They can be used instead of the writing subject. If the master does not have a pencil or marker at hand, he can mark the beginning of the measuring object with serrated marks at the end of the roulette to mark the place where you need to cut the excess.



Why on the hook hole A still in the hook there is a small hole, which is located above the geared edge of the roulette. This hole is necessary in order to be able to catch the edge of the roulette screw or nail and measure the flat surface without the help of a partner.



The same hole can be used as a compass. If you need to draw the perfect circle, twist the screw in the middle of the material. Then trailer to the head of the screw hook, stretch the ruler to the desired radius and fix the line with a retainer. Now it remains to turn the ruler 360 degrees - and the ideal circle of the desired diameter is ready.



Roulette can be used to divide an object into equal parts without computation. For example, if you want to divide an object into three equal parts, choose a number on a ruler multiple of three. It's three parts of 10 cm. Just put the ruler on the part so that the zero point was on top of the part, and at the bottom there was a mark of 30 cm on the ruler, and make marks of 10 cm on the details.



We hope that the planned repair will become a little easier after you have learned how to use roulette effectively and easily. What facts were not obvious to you?
