Quite often, many of us have to deal with paper, making all kinds of crafts out of it. The main initiators of this exciting activity are children. This is not surprising: paper is a very grateful and pliable material, it is easy to work with it.
Let's see how to make a cylinder. In the future, this can be useful to us if you suddenly need to make a cylinder hat or any other craft that has a cylindrical shape. We will not find anything like this in stores. It remains only to rely on your head and hands.
How to make a cylinder out of paper?
Nothing complicated here. For this work, we need some materials and tools. They are in any home. These are paper, pencil, compass, ruler, scissors, triangle and glue for paper. All this is already laid out on the table.
The cylinder consists of two identical bases and a surface called the side. The basis is two symmetrical circles, we cut them first. Before you make a cylinder, you need to determine its diameter. Dividing it into two, we get the radius, the numerical value of which is set on the compass, using the ruler for this.
Scissors cut the first circle. In the same way we mark and cut out the second circle.
Further it will be a little easier.
Before you make a cylinder of paper, you must determine its height, it will also be one of the sides of the rectangle. From this rectangle we will make the lateral surface of the cylinder.
To the size of the height of the cylinder, you need to add 10 millimeters on both one and the other side, and draw lines. This is an allowance for bonding substrates.
On the allowance, cut out the triangles. Their height will be equal to ten millimeters. To determine the parameters of the second side of the rectangle, multiply the diameter of the base by 3.14. This will be the circumference (DO), which is calculated by the formula
l = ΟD = 2Οr
l - DO; d is the diameter of DO; r is the radius of DO; Ο is the mathematical constant β 3.14.
We have chosen the numerical value of the diameter earlier and we know it. Substituting these values ββin the formula, we get the size of the second side of the rectangle. We add another 10 mm to it and draw a line with a pencil. This strip is an allowance for bonding. We smear the allowance with glue, turn the rectangle into a pipe and glue it along the mark. Let the glue dry. We bend the teeth of the pipe inward, grease their outer part with glue and glue the bases to them.
That's all. We not only answered the question of how to make a cylinder, but also made it out of paper.
Holding it in your hands, it is easy to realize how to make a cylinder out of cardboard. The algorithm of actions will not be different from that described above.
The difficulty will cause only the rigidity of the cardboard. More efforts will have to be made by cutting out parts and bending bonding allowances. If necessary, a cylinder made of paper or cardboard can be painted with paint of the desired color or varnished.
Craftsmen say that paper crafts need to be created only in a good mood, because "paper" creations store a particle of the human soul and give its energy to the addressee.
