It happens that with fresh young vegetation trimmer easily, but there is a desire to clear the space behind the fence or along the access road, and the tall ripe grass is the technique of “not too tough”.
We offer the option of self-production of the nozzle for the trimmer from simple, almost improvised, means. You will need a metal perforated plate (100 mm x 240 mm), two hacksaw blades for metal, 4 screws and 4 nuts, 4 washers and 4 enlarged washers. From the point of view of safety, hacksaw blades should not be completely hardened.

The hardest part of the manufacture of the nozzle symmetrically to mark and carry out the holes for the knives and the shaft of the trimmer. That is why the finished perforated plate is chosen.
You must first make the base of the nozzle. This metal sheet grinder cut a square of side 100 mm. Mark it is necessary so that the exact center (at the intersection of the diagonals) there was a hole. To do this, measure the distance of 50 mm from the center of the selected hole perpendicular to the short side of the plate and plan the cut lines.
