Quite often, many of us have to deal with paper, making all kinds of crafts from 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.
Let's see how to make a cylinder. In the future, this may come in handy if you suddenly need to make a cylinder hat or any other craft that has a cylindrical shape. We won't find anything like it in stores. It remains only to rely on your head and hands.
How to make a paper cylinder?
Nothing complicated here. For this work, we need some materials and tools. They are in every home. These are paper, pencil, compasses, ruler, scissors, triangle and paper glue. All this is already laid out on the table.
The cylinder consists of two identical bases and a surface called the side. The base is two symmetrical circles, we cut them out first. Before you make a cylinder, you need to decidewith its diameter. Dividing it by two, we get the radius, the numerical value of which is set on the compass, using the ruler for this.
Cut out the first circle with scissors. In the same way, mark and cut out the second circle.
Then it will be a little easier.
Before you make a cylinder out of paper, you need to determine its height, it will also be one of the sides of the rectangle. From this rectangle we will make the side surface of the cylinder.
To the height of the cylinder, add 10 millimeters on both sides, and draw lines. This is the allowance for gluing the bases.
On the allowance cut out triangles. Their height will be equal to ten millimeters. To determine the parameters of the second side of the rectangle, it is necessary to multiply the diameter of the base by 3, 14. This will be the circumference (DO), which is calculated by the formula
l=πD=2πr
l - BEFORE; d is the BS diameter; r is the BS radius; π - mathematical constant ≈ 3, 14.
The numerical value of the diameter we chose earlier and we know it. Substituting these values into 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 gluing. We smear the allowance with glue, fold 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.
Here it isall. 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's easy to figure out how to make a cylinder out of cardboard. The algorithm of actions will not differ from the one described above.
Difficulty will cause only the rigidity of the cardboard. More effort will have to be applied when cutting out parts and bending allowances for gluing. 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 should be created only in a good mood, because "paper" creations store a particle of the human soul and give its energy to the addressee.
