How to make an original shelf for a house with your own hands? Step-by-step description of the stages of work, diagrams and photographs

Making a semicircular shelf is not as difficult as it seems. Attentiveness, accuracy, some knowledge of geometry and you will succeed.

Necessary tools and materials

• multilayer plywood or flat boards;
• ruler, pencil, gon, compasses;
• electric jigsaw;
• surface grinding machine;
• sheet of paper or paperboard (such as packaging from the refrigerator);
• grinding skins of different granularity;
• putty;
• glue and primer;
• aerosol paint.

The best material for a shelf is multilayer plywood. For large shelves, thicker - 18 - 20 mm, for small ones (up to 50 cm in diameter), thinner - 10 - 12 mm.

Stages of work

As an example, let's consider making a small semicircular shelf.As we can see, the shelf consists of vertical andhorizontal elements. We will call the vertical ones uprights, and the horizontal ones - shelves. In the plan, the shelf fits into a circle. We will call this circle the base of the shelf. We draw the base (preferably in full size), mark the location of the uprights and shelves on it, taking into account the thickness of the material.We select the width of the shelves and racks. We draw a template.Its base is equal to the diameter of the circle -base of the shelf, from the middle of the base we put aside upwards a little more (approximately 5 - 10%, depending on the size of the shelf) than the selected width of the shelves. This will be the height of the arc. We draw an arc, the radius is found by the formula, where a is the height of the arc and, accordingly, the width of the racks and shelves, b is the length of the base of the element, R is the radius of the circle that meets the requirements of a and b. We make a template in natural size. Based on the template, we mark the middle. Each element has two sides; the side closest to the center of the circle-base we will call the inner, the farthest - the outer. From the middle of the template base we markdistance to the inner side of the rack (or shelf) (P), at this point we draw a perpendicular from the base to the arc, the size of the perpendicular is the height of the arc of the rack (or shelf) (a). The length of the base of the rack (b) is determined according to the drawing of the arrangement of the elements (therefore it must be made in full size).Moreover, we measure the size on the inner side. Having all the necessary dimensions - a and b - we calculate the radius R and draw the markings on the workpiece. To make marking easier, you can usethe simplest device: a flat board, draw a line along the long side in the middle, attach a stop perpendicular to the line, mark the middle line on the stop. On the workpiece, mark the length of the base, the middle of the base, place the workpiece on the device, rest it against the stop, align the middle marks. Mark the value R from the ends of the base on the middle line. Place the compass needle at this point and draw an arc on the workpiece.If the value R is large and there is no suitable compass, then you can make a temporary compass from a flat strip (the design is shown in the figure).We mark all the others in the same way.elements. After marking, we cut out the elements with a jigsaw. On the racks and shelves, we mark the intersection points according to the markings on the base of the shelf.We make samples for connecting elements in half-timber. On the racks from the arc side, on the shelves - from the base side. Let's connect.If all the elements are in their "right" places, we assemble the structure with glue. We pay attention that the elements are perpendicular. After assembly, the structure looks like the one in the picture.Let's start finishing. We bevel the outer edge of the elements with a grinder or manually so that they have a spherical appearance.We smooth out the sharp edges evenly with a sander.sandpaper. Prime. Putty. Clean. If necessary, repeat the process until smooth surfaces are obtained. Next, prime for painting and paint with spray paint. Important note. If no other type of fastening is provided, then at the fitting and assembly stage, it is necessary to drill two holes in the second shelf from the top for hooks - dowels. Choose a place for the holes that is inconspicuous, closer to the racks. Step back from the rear edge and the rack by 1 - 1.5 cm. We screw the hooks into the wall and hang the shelf on them. Bonus. It is very convenient to use a homemade device for sanding.
