Is it possible to drill holes in various materials with a brush cutter? Today we will look at one of the options for this possibility.
The idea is to make a rigid frame in which the trimmer will be placed and equip the spindle with a standard chuck.
Will need
A small quantity of round and profile pipes, sheet metal, fasteners (bolts, nuts, washers, screws) and a regular cartridge will be required.
Tools you will need:
- grinder with cutting disc;
- welding equipment;
- bench vice;
- drill with drill bit;
- hammer;
- hand screwdriver;
- screwdriver and wrenches.
Technology for converting a trimmer into a brush cutter
It can be divided into 2 stages: manufacturing a rigid frame and installing the lawn mower engine into the frame.
Making a rigid frame
We begin the work by making a base - a rectangular plate of appropriate dimensions, with mounts for the engine.
We weld a square pipe from the bottom to the short side in the center, which should partially protrude outward.
We weld a “leg” vertically to its protruding edge - an oblique adapter with an overlapping plate welded to it with a cylindrical lower part and two holes at the ends.
We turn the base over and to the front side, on the edge opposite the “leg”, parallel to the short edge, we weld a rectangular pipe flat across the entire width of the base.
We vertically weld a support stand with a cylindrical cutout and two holes at the cutout level to the outer side of the profile pipe in the center - this will be the mount for the fuel tank.
Opposite the first post, on the other side of the plate, we weld a second one with a rectangular cutout. The cutouts on the stands and the distance between them are made taking into account the shape of the trimmer body in the support areas.
We vertically weld a round pipe to the front part of the profile pipe protruding from under the base plate, closer to the outer edge - this will be the mount for the control handle.
Using a grinder, we cut a piece from a pipe with a large rectangular cross-section that is 2 times longer than the width of the base plate.
We lay it flat on the base from the back side symmetrically to its center and under the profile pipe from the front side. In this position, we weld the pipe to the base.
We take two pipes of the same diameter and length and, in parts, closer to one edge, we make notches with a grinder in order to smoothly bend them in this place, hitting with a hammer the upper end of the pipes, the bottom of which is clamped in a vice.
We install the bent blanks with the long part on the front side of the profile pipe so that their upper ends meet. We brew them in this position at the bases and at the junction.
We grind all the welds, the edges of the holes and the edges of the parts of the resulting structure using a grinder with a disc. The rigid frame is completely ready.
We mount the motor of the brush cutter into the frame
We place the motor in the frame so that the clutch housing rests on a stand with a cylindrical cutout, and the starter on a rectangular one.
We secure the engine to the stands with two screws at the front and rear.
We fix the control handle on the vertical pipe in a position convenient for the hand.
We connect the fuel supply and drain pipes between the gas tank and the engine carburetor. We secure the gas tank with two screws to a plate with a cylindrical bottom surface and two holes.
We turn the engine fixed in the frame over and weld two legs to the profile pipe, which, together with the gas tank, ensure a horizontal position of the engine on a flat surface.
We weld the cartridge to the engine shaft, maintaining alignment. We clean and grind the joint with a grinder. The trimmer motor is completely ready for drilling.
Reality check
Fill the tank with gasoline and tighten the gas tank cap tightly. Insert and secure the drill in the chuck.
We start the engine and let it run without load. Drilling into solid wood. The unit copes with this task with ease.
The plastered brick wall gave way without difficulty. The drill, even at medium engine speeds, easily overcame the resistance of the brick.
The most serious test is drilling holes in a profile steel pipe. We punch a number of points and start drilling. Metal also did not become an obstacle to our homemade product.
