If you are the owner of the land, then at least once you have encountered the need to dig holes for supports and poles when decorating the appearance of the territory. Sometimes it also happens that a hole is required in a not very convenient place. With a simple shovel, this task is quite difficult to cope with. You can, of course, borrow a hand drill from your friends or call a specialist who manages the appropriate tool. But if you plan to carry out such work from time to time, then a garden drill for poles with your own hands can be made from improvised materials.
The tool will be convenient to use and compact, which is very convenient for storage. Usually hard metal is used for such work. With it, you can split the rhizomes of plants and small stones into pieces. Such a device will allow you to dig a hole by rotating the equipment around an axis like a corkscrew.
Cutting part selection
Basicthe purpose of the drill is to dig holes. Wells are made by the cutting part, which can have different shapes, namely:
- half-disc shape;
- screw type;
- two-bladed;
- helical;
- removable;
- tiered;
- whole.
If you want to make a drill for poles with your own hands, you must determine the design features of the device. Some models have small blades at the bottom, while they increase to large sizes at the top. By purchasing a factory drill, you will receive an effective and functional tool for use. But it is not always possible to introduce it into the soil to the desired depth, in addition, the nozzles of such devices may not have the diameter that is needed.
Why you should make your own drill
Although the cost of a factory drill is affordable, you can make it yourself, getting a tool that will meet all the requirements. The technology of the work is very simple, and the cost will be much lower. It is only necessary to decide what parameters the product will have.
What size to choose for the drill
The most common garden auger sizes, in terms of diameter, range from 100mm to 300mm. The height of the working part should be approximately 400 mm. The angle between the discs is limited to 25 to 28 ˚. You must choose the height individually, because it will depend on your height.
Recommendations for making individual parts
Beforeto start making a drill for poles with your own hands, you must deal with the components of this tool, among them should be highlighted:
- baking powder;
- soil receiver;
- shaper plow;
- auger.
The baking powder consists of two planes or an auger. The latter looks like a spiral, in this knot the knife is located on the bar. There is also a soil receiver in the storm. Soil is collected here, which makes drilling holes up to 35 cm in diameter easier. This node allows you to strengthen the column foundation, which is required when erecting large buildings.
Recommendations for making auger
There is a drill and an auger. It must be fixed to the handle with bolts. The length of the finished product, which can be used in work, is a meter, which allows making holes up to 70 cm deep. If the hole should have a more impressive depth, the structure can be built up with a half-meter tube. This element is a part with a bolt and nut, which are located at the ends of the pipes.
Preparation of materials
If you decide to make a drill for poles with your own hands, then at the first stage you need to start preparing everything you need. Among the details to highlight:
- nut;
- drill;
- vices;
- pieces of metal pipe.
You will also need an M 20 bolt. You need to take 2 disks,diameter from 100 to 150 mm. As for the drill, it must have a tip, while the diameter is 20 mm. The metal pipe will underlie. You will need two pieces of 500 mm and one - for 400 mm. It is better to take a pipe with a wall thickness of 3.5 mm and an outer diameter of 40 mm. With these parameters, the finished product will be durable and will be able to withstand hard ground.
Preparation of tools
You can borrow discs from a regular circular or make them yourself. To do this, you should find 3mm sheets of metal. Among the tools that will be needed in the work, it should be highlighted:
- angle grinder;
- welding machine;
- metal drills;
- hammer;
- drill.
If you do not have a tip with a drill, you can replace it with a drill with a shank that looks like a cone. Its diameter must match the screw. In order to avoid injuries, you should use soft bike handles.
Step-by-step work
If you decide to make a hand drill for poles with your own hands, draw a circle with a center on a metal sheet. This part will be the blade. The circle is cut out by a grinder, after which a cut line should be drawn along the diameter line. At the next stage, you need to draw a cutout line that will correspond to the circumference of the collar. The disk is divided into two parts, after which a hole for the collar should be cut. At the end of the pipe that will perform the functioncrank, with an angle grinder it is necessary to make four longitudinal lines. A point is formed from them with a hammer. At the same time, cuts must be made at the very center of the pipe.
The tip is processed by welding. The collar during operation should not be clogged with soil. When making a drill for fence posts with your own hands, in the next step you will need to connect the disc to the wrench using a weld. This is done at a distance of 5 cm between them. It is necessary to observe the angle of the plane of rotation, which is 20 ˚.
Working on the extension pipe
Next, you can start working with the extension pipe. It must be equipped with a handle. This part is welded in the form of the letter T. An amplifier in the form of a scarf is attached to it. The workpiece should be threaded into the collar, making a hole between these parts. This will allow you to fasten the parts with a hairpin. There should be several holes so that the length of the product can be adjusted. You can complete the work process by sharpening the blades. The edge of the cutter is machined so that the point is pointing down when rotated.
Protective coating application
Having made a drill from a pipe for poles with your own hands, you must protect it from external influences and premature aging of the material. This will prevent the occurrence of rust. Details of a homemade drill are processed with sandpaper and coated with a primer. A phosphating solution is applied on top. The finished product after such processing can be painted.
When using the tool after eachapplications, it is usually disassembled and cleaned from dirt and dust. Particular attention should be paid to connections. They are coated with a special lubricant that helps repel water. Do not miss this moment, because proper care will be an excellent prevention of jamming bolts and allow the equipment to work smoothly for a long time.
How to improve the tool
When you make your own DIY garden post drill, you might want to consider upgrading it. When drilling holes, you may encounter large rhizomes that are densely embedded in the ground. Sharp edges make work easier. The sloping area of the blade should be serrated or rounded for ease of use.
The design can be improved with the addition of removable cutters. They will allow you to drill holes of any diameter. In addition to the manufacture of spare parts, it is necessary to provide for their attachment to the collar. They are connected by two plates of iron, fixed by welding. Two bolt holes are drilled in the mounting plates and blades. The cutters are fixed with M 6 bolts. During operation, the bolts can interfere. To eliminate such a problem, they are screwed in with the thread up.
If you want to make the best do-it-yourself pole drill, you can improve it using another method. To do this, a narrow metal plate is cut out, which is machined in the form of a cone using a grinder. This will increase the efficiency of the lower end of the crank. Plate dimensions -10 x 2 cm. As a result, you should get a kind of point. It is not necessary to make incisions in the collar. Metal plates are inserted into the end, which are fastened by welding. They are flattened, which will allow you to get a pike.
If you want to use a pike, you can use a different method of making it as a basis. For this, a 17-centimeter metal plate is taken, from which an auger is cut, similar to a corkscrew. The algorithm of actions will be the same as in the first option.
If you decide to make a drill for poles with your own hands, photos of such designs will allow you to understand which design to give preference to. If an auger is provided, a drill can act as its role. It should handle wood and metal. Such a tool will be easier to enter the soil and will drill holes of the desired depth.
If you work with dense deep soil layers, you can weld a small flat cutter between the cutter and the peak. This design will loosen the earth and center when drilling. For such a part, two metal plates 3 x 8 cm are needed. A trick of this kind will speed up the work with the tool.
When making a drill for installing pillars with your own hands, you can supplement it with cutters from disks that are designed to work with stone. Circles are cut along the radius, and in the center the hole expands. It should correspond to the diameter of the collar. Disk bendallows you to get a semblance of a screw or a corkscrew. This part will only need to be welded using the algorithm described above.
Cutter can be made from a circular saw blade. The tines will handle rhizomes and hard soil. You can upgrade the tool as you wish. But no matter how high-quality it is, it is better to loosen the soil with a shovel before drilling, then the device will enter the soil well, and the work will go faster.
In conclusion
Garden drill can also be bought at the store. But such tools are not always suitable for working with difficult soil, which may be in your area. With just a little time, you can make your own tool that will fit in all respects. We hope our advice will help you with this.
