In this article, the author of YouTube channel "izzy swan" will tell you some secrets of using ordinary roulette.
Materials
- plywood sheet
- Neodymium magnet.
Instruments, used by the author.
- tape measure, pencil
- Square.
As often happens, we climb a ladder and, being on top, drop a tool - a hammer, a wrench, etc. The very idea that you need to go all the way down and back up again brings a lot of unpleasant experiences.
But if you accidentally got roulette nearby, consider the problem solved. The author has long attached a neodymium magnet to the end of the roulette just in case. All you need to do is pull the tape to the desired length and hook the tool with a magnet. It will certainly be taken if it has at least some metal on it and if it is not too heavy. Although almost all roulettes are equipped with a magnet on the trailer.
The following technical trick has many names, but the author calls it the "carpentry rectangle" or spirit level. Usually, in this case, the calculations are carried out in centimeters, but in this case the author will count in inches. If you need to measure the plane at an angle of 90 degrees, put a mark in the place from which you need to postpone the plane, mark 6 inches.
And then measure eight inches from the original mark.
Set aside 10 inches from these two marks, and at the point where the line measuring 10 inches intersects the line indicating 6 inches, it will be exactly 90 degrees from your primary mark. This is the "carpentry rectangle."
The following trick, for sure, many know. But for those who are not in the know, it will be very useful. If you need to find the center mark of any measurement, simply fold the tape measure in half. Attach the upper part to this measurement and on the top of the rounding, where the fold is, there will be exactly half the distance.
If you need to find the circumference, approximate length, say, when cutting an edge of a certain length, all you need to do is measure the diameter of the circle with a tape measure, add one centimeter, and fold the tape measure three times, totaling 49 centimeters. And here is how it works: the diameter of the circle is 15 and 1/4 cm, multiplied by three is 47.8 cm. The error is a little more than a couple of centimeters.
The next trick will come in handy rather for fun. If you want to know how old a person is, and you know the year of his birth, find the mark of 100 cm on the tape measure and add the number for this year.For example, now 2015, we reach the 100 cm mark, and plus 15, we block the tape in this place, and attach its end here. Now we return to the year when the person was born. Suppose, 1973, we turn the tape over and ... he is 42 years old.
And it works along the entire length of the tape! If you were born in 1990, we turn over - you are 23 years old.
