DIY coffee grinder

Coffee is the most delicious and aromatic invigorating drink. In most cases, lovers prefer ground coffee brewed in a Turk - this way you can feel all the splendor of the taste of this drink. But to grind the beans, you need a coffee grinder. In this article we will look at how to assemble this device yourself.

Design and principle of operation of a coffee grinder

A coffee grinder is designed to grind coffee beans into powder. Let's look at the principle of its operation:

• beans are poured into the upper part of the coffee grinder;
• the millstones located inside grind the grains to the desired size using a handle that is located outside and, using the movement of the hand, causes the movements of the millstone mechanism;
• The ground coffee goes into a specially built-in collection container and is ready for preparation.

IMPORTANT! The best choice would be a coffee grinder with a handle located on top.

DIY coffee grinder

We offer two options for assembling this device with your own hands: manual and mechanical.

Assembling a manual coffee grinder

For manufacturing, you need to prepare the following materials:

• thick cardboard;
• sheet of plywood or particle board;
• gun with silicone glue;
• knife;
• handles from furniture drawers;
• small spatula;
• wine corks;
• a small glass of sour cream;
• stainless steel cover;
• coffee beans;
• acrylic paint.

To make a stand for a homemade coffee grinder, we will prepare a sheet of chipboard or plywood measuring 14 cm by 14 cm and four sheets of cardboard measuring 13 cm by 13 cm. Then we glue three cardboard sheets together and take measurements of the shelf, which is installed at a distance of 4 cm from the bottom of the structure. Glue the last sheet of square cardboard and cut a hole for the box above the shelf. We cut out and assemble the box according to the appropriate dimensions of its parts so that it fits into the prepared hole, then we attach a handle to it. We glue a square of chipboard and a square-shaped board on top in the form of a stand for the unit itself.

To make the grain grinding device itself, we will take: a sour cream glass, an ice cream stick, a furniture handle, a bottle cap, a board in the shape of a circle with a diameter of 2 cm and a cardboard circle.

We glue a stainless lid to the stand, fasten the cup on top, and on top of it we install two circles of different diameters, the first from cardboard to cover the entire surface of the cup, the other from a board. We fix the furniture handle to the stick, and then to the board. We glue a cork to the other end of the stick for convenience.

To decorate, we paint our device with acrylic paint, the color you like, let it dry and glue the grains or other decorative elements. This DIY device will be an excellent kitchen decor.

How to assemble a mechanical coffee grinder

To make a mechanical device you will need the following tools:

• Electrical engine;
• sheet of tin of medium thickness;
• drilling machine;
• Grinder;
• sandpaper;
• metal processing tools;
• vice;
• file;
• bolts;
• wooden blocks and boards.

Having prepared all the materials, we begin to assemble our device:

1. We take an unnecessary electric motor, the power of which is from 300 W to 700 W, and disconnect its parts. Disconnect the rotor from the stator.
2. Using a drilling machine, we make holes inside the rotor with d = 10 cm and a depth of 0.7 cm, at a distance of up to 1.5 cm from each other. We place the holes along the length of its rod from top to bottom, along the lines that are located at an angle.
3. We connect the prepared holes with grooves, 0.4 cm wide and 0.5 cm deep. The grooves are well secured in a vice and made with a corner grinder. Very carefully process the grooves that are located at the bottom of the rotor.
4. Using sandpaper, chamfer the top of the rotor so that the height is about 1.5 cm and the depth is 0.8 cm.
5. We insert the rotor into the stator and make small holes for the grains in its covers.
6. We will make the loading container from a sheet of tin, the dimensions of which will depend on the size of the engine.
7. We attach a handle to the top of the motor shaft, which will give the rotor a rotational movement. We secure the handle in the rotor with a bolt.
8. We screw the resulting device to a board, inside of which you first need to make a hole - ground coffee will come out through it. We place a small container under the coffee grinder into which the final product will be poured.
9. When this device is ready, you need to make several turns in one direction and the other.

The mechanical coffee grinder is ready.
