From time to time there is a problem of sharpening a knife for a meat grinder. With a dull knife, she begins not to chop meat, but simply wind it on a knife. For sharpening a knife, one simple device will help, which is easy to do yourself.
How to make a sharpener
In order to make a device for sharpening a knife, you will need several square sheets of cardboard, glue, sandpaper, a hacksaw, a file and a drill. Square sheets of cardboard are glued together with a height of 5 or 6 millimeters. It is best to use Moment glue for gluing cardboard, rather than paper glue. After the cardboard sheets are coated with glue, they must be put under the press. A small stack of books or magazines will burn the press.
Next, we take out the grill from the meat grinder. We put the lattice on top of the cardboard and draw it with a pencil on the cardboard. We cut off the unnecessary parts of the cardboard with a hacksaw for metal or with a regular clerical knife, as shown in the figure, until a polygon is obtained. The sharp corners of the polygon are smoothed with a file until an even circle is obtained. In the resulting circle, cut a small groove 3 mm wide. He will keep our device from rotating. You can make such a groove with a file edge or a tetrahedral file. In the center of the resulting workpiece, drill a hole the size of which is similar to the diameter of the shaft of the screw of the meat grinder.
On the upper side of the circle, glue sandpaper with a grain size of at least 200 units. The hole in the sandpaper must be pierced with a clerical knife.
