A do-it-yourself rig for drilling wells is made according to the free drawings presented below. Taking into account the purchase of all components, the cost price of a home-made mini drilling rig for water will be 15-20% of a similar finished unit.
This diagram shows the main working units of the MGBU, which you can manufacture according to our drawings.
Racks for the frame on the drilling rig are made of DU40 pipe, wall thickness 4mm. "Wings" for the slide carriage - made of DU50, thickness 4mm. If not with 4mm wall, use 3.5mm. Download do-it-yourself drawings for a water drilling rig:
At first, it is recommended to purchase the drilling swivel and drill rods ready-made. In the manufacture of these parts, machining accuracy is very important, since the load on these nodes is large. We do not recommend making a swivel from available tools. One slightest inaccuracy - and it will fail.
If you decide to order a swivel from a turner, you will need to find a qualified specialist, and preferably with modern CNC machines. Swivels and locks require very specific types of steel. For locks - 45 steel. For the swivel - 40X. Download a drawing of a homemade drilling swivel:
Attention! Private traders will not do high-quality hardening! Grinding is required after hardening. Use HDTV hardening, but this is an expensive procedure.
You can save on buying ready-made units, but it will take a lot of time to find a suitable master. But it's worth it - homemade parts are much cheaper than purchased ones. To get started, purchase parts for samples. Turners work better when they have drawings and templates in their hands.
If you have factory samples, it will be much easier to check the quality of work. For example, if a turner made drill rods (locks), then you take factory and home-made parts and screw them to each other - check the quality of the thread. The match must be 100%!
Do not buy parts on delivery. This is necessary in order not to buy a marriage - this, unfortunately, happens. And most importantly, if you order delivery from afar, then you can wait more than one month.
We advise you to make the thread on the drill rods a trapezoid - it is not worse than the tapered one, but if you then order the turners, then it is more difficult to make the tapered thread.
If you make or buy locks for drill rods separately, then take simple suture pipes for the rods, if you drill no deeper than 30 meters (3.5 mm thick and the inner diameter is at least 40 mm). But a professional welder should weld the locks to the pipes! In vertical drilling, the loads are large.
For drilling deeper than 30 meters, you need to take only thick-walled pipes (with a wall of 5-6 mm). Thin rods are not suitable for great depths - they will break. Download drawing of drill rod locks:
It's easy to make a simple drill yourself. A drill is made from ordinary steel. If you decide to make it from alloyed, then keep in mind - it's difficult to weld! We need a welder. If there are a lot of stones at the drilling site, then buy special drills from firms, adapted for strong soils. The higher the price, the harder the alloys on the drills and the stronger the drills themselves.

VIDEO In the manufacture of a mini drilling rig, a "RA-1000" winch is used. You can take another one, but preferably, with a carrying capacity of at least 1 ton (or better, more). Some drillers install two winches, one electric and the other mechanical. In the case of a drill string wedge, it helps a lot.
To facilitate the work, it is advisable to buy and connect two consoles: one is the reverse and the engine stroke, the other is for the winch. This will save a lot of effort.
A gear motor for a self-made mini drilling rig will be required for 60-70 rpm, with a power of 2.2 kW. Weaker will not work. If you use a more powerful one, you will need a generator, since you will not be able to connect to a voltage of 220 volts. Recommended for hydrodrilling geared motor models: 3MP 31.5 / 3MP 40 / 3MP 50.
1. Purchase of drill rods and swivel (note that the parts have the same thread, or use an adapter). To get started, you don't need to buy a lot, focus on a depth of 30 meters.
2. Purchase of a motor-reducer. These purchases are time consuming and often have delays that are beyond your control, so it is best to buy in advance.
3. Manufacturing of a frame and a drill. When making a frame, it is advisable to have a motor, a swivel and a winch on hand, since all this must be attached to the frame. It is also problematic to make a carriage without a motor on your own, since the fastenings for different motors may differ.
4. We buy the remaining components of the mini drilling rig after installing the main units on the frame.

It is recommended to start water drilling from shallow depths in order to gain at least a little experience. Experience in vertical drilling is the most important thing! You can only learn how to drill water wells in practice. Learn to avoid the wedge of the drill string. Newbies out of inexperience often “catch the wedge” and lose their drill rods. Sometimes the drill jams so much that it is impossible to pull it out even with a crane, the structure simply comes off (usually at the welding points).
Mistakes come at a cost - an expensive tool is lost. Therefore, in hydraulic drilling, it is impossible to force events and immediately make deep wells. Approach this matter responsibly and carefully. Read literature and books about water wells. This work requires a lot of knowledge that cannot be conveyed in a nutshell, so self-education is a must.
When performing water wells, as with any production process, performers strive to increase productivity as well as process efficiency. Regarding the mentioned process, it is an increase in the rate of drilling a hole and optimization of unproductive losses in auxiliary operations. The first factor can be improved by softening the rocks by supplying water to the work area.It will also help to increase the survivability of the drilling tool as a result of its intensive cooling and lubrication, especially if the fluid is a clay mud with antifriction additives. Here, a contradiction arises between the rotary motion of the drill string and the stationary position of the fluid delivery device. It is solvable if a swivel is used for a small-sized drilling rig.
Fig. 1. Drilling swivels for MGBU, on the right - homemade, on the left - in an industrial version
As you can see from Fig. 1 (left), this product consists of several simple parts:
top and bottom flanges;
internal partitions with grooves for sealing rings in the amount of 2 pieces;
a body made from scraps of thick-walled pipe;
metal bar;
of the standard parts, the following are applied:
Obviously, such a unit can be made with your own hands if you have access to turning work, you just need to make a drawing or sketch of each detail.
Various design solutions are possible using stuffing box seals, other types of bearings, etc., providing the main purpose of the unit - interrupting the rotational movement of the drill string and supplying it with water, air or mud.
This unit is an intermediate link between a translational hoist, a hose for supplying liquid or gas, and a rotary drill string. The supply hose is connected with the second end to a pump or column for supplying the working composition.
Fig. 2. Various modifications of swivels for drilling with flushing fluids
The body of an industrial swivel is made of cast iron or steel, depending on the design dynamic and static loads on the unit. It provides filling and drain holes, as well as a viewing window to control the oil level in it - at high loads, a large amount of heat is generated in the mechanism. A mandatory element is a breather to relieve pressure when the swivel becomes very hot during operation. The bearing is selected based on the working conditions in the thrust design, since the loads from the drill string are very significant, they increase as its height increases.
A general idea of the designs and modifications of swivels for drilling water wells is shown in the drawing in Fig. 2. Of course, they are unsuitable for do-it-yourself execution, but the drawing gives an idea of the applied principles of designing products for this purpose.
Fig. 3. DIY Drilling Swivel Diagram
The schematic drawing in Fig. 3, for the simplicity of execution, makes it possible to make a unit with your own hands, you may have to agree on the dimensions according to the dimensions of the installation and the drilling tool.
Mini-rigs for water drilling, made by hand, have a design feature, consisting in the transfer of all axial loads precisely through the swivel. This happens both during drilling and when lifting the working tool. In addition, this unit is actively exposed to abrasive materials when pumping the flushing solution.
Given the difficult operating conditions of the unit, materials for making it with your own hands should be selected with great care, based on the following considerations:
manufacturing in a home workshop is impossible without the use of welding, therefore, it is necessary to select metal of steel grades with high or normal weldability, which implies the use of low-carbon materials;
the swivel of a mini-drilling rig works in direct contact with a compound with strong abrasive properties, which implies rapid wear of the contact surfaces, which determines the use of a material with the ability to resist wear;
in the process of drilling, this unit experiences significant mechanical loads, since it is a transmission link for them, therefore, materials are needed that can carry them.
Based on the set of requirements, it is possible to propose the use of steel grades 13GS, 17GS or 17G1S-U. With this carbon content, these materials weld well. The presence of manganese (G) in the composition of the metal determines its property such as increased wear resistance and the ability to self-strengthen under the influence of abrasive media. And in combination with an alloying addition in the form of silicon (C), it determines the sufficient strength characteristics of the material. These grades of steel were developed as a multi-purpose structural material and it should not be difficult to find it for the manufacture of parts.
The part drawing must contain all details of the required tolerances and treatments that will ensure long-term performance of the assembly, taking into account the performance of purchased items, including seals and bearings. The best way to avoid mistakes is to coordinate the drawing with an experienced designer.
A drill rig made with your own hands, and even more so with the possibility of high-quality flushing of the wellbore, can not only facilitate the resolution of issues at your site. This is a direct way to organize your own business based on the investments made in the equipment.
Based on the information obtained from this article, having shown accuracy and ingenuity, it is likely that a mini-drilling rig made with your own hands, including a swivel, will work for a long time and reliably. I wish you success!

In order to install the installation for drilling water wells, you can use the services of qualified specialists, but, unfortunately, not everyone can spend a round amount of money on this. In some cases, installation by professionals is not possible due to certain site conditions. Then all that remains is to assemble the equipment with your own hands, and then if you have knowledge in this area and at least a little experience.
To have an idea of what a drilling rig is, you should consider some of its types:
Small-sized equipment of small dimensions of the shock-rope type;
Auger machine that performs work without flushing wells;
Rotary drill, additionally flushing wells with the removal of rocks to the surface of the soil.
Such equipment is used most often, and in the conditions of small private territories, mini-installations are common in which a shock-rope system is used.
Typically, MGBUs are made up of drills of standard diameters. Such equipment is controlled by means of a load control unit, as well as including different modes of engine operation.To lift the bar, a winch is used, which makes it possible to withstand loads up to 4 tons.
The small, highly sought-after models drill up to 70 meters deep. Very often, manufacturers can manufacture equipment for the required customer order.
At the same time, drilling equipment is capable of working not only vertically, but also drilling at a certain angle.
Different types of structures can work with:
Electricity;
Diesel fuel;
Pneumatic equipment;
Hydraulics.
Small dimensions allow using minimal human resources and convenient transportation of the unit. This explains the popularity of this type of drilling equipment.
This technique is in demand and is often used in the personal household. Its convenience and portability make the model popular among summer residents and owners of private houses.
This is not surprising, because it has its own advantages:
The drilling equipment is easily transported, its installation is characterized by simple preparation and easy installation;
Equipment and materials at hand can be purchased at any time, due to the wide range and availability;
At the same time, the technique can be used to create a foundation and other construction work;
The construction does not require a large number of maintenance personnel;
The equipment is mobile and has compact dimensions, therefore it is suitable even for a small area;
The system can be powered by a generator. With all its positive qualities, the building, moreover, is affordable. If desired, the drill for the installation pillars, like other parts, can be made on your own.
The drilling rig consists of an above-ground and an underground part, connected to each other.
The aboveground part includes:
Oil rig;
Onshore drilling equipment;
Equipment to ensure the descent and ascent;
Drive unit;
Drilling fluid system.
Towers are mast and tower and are made of rolled steel or pipes. The tower tower includes: a balcony, gates, trestles, platform, ties, stairs, belts.
In turn, the mast tower is single-support and the most common - two-support.
The main elements of the mast: sections, a fire ladder, installation trestles, ladders (tunnel and marching), stretch marks, a balcony, a safety belt, an under-crown block frame.
The main characteristics of the tower are its height, carrying capacity, capacity to install pipes of different sizes, as well as the dimensions of the base, weight and size of the candle. The higher the setting, the deeper the drilling is possible.
As a rule, any installation includes the main units. Drilling mechanisms include: auger, winch and hoist, hydraulic rotator - drilling gear. Energy technology can consist of internal combustion engines, it can be any motor - electric or hydraulic motor.
Appliances with gas, liquid or mixed cleaning agents - swivel, pipes, mud pump, hoses.
In addition, the plant is equipped with a control and measuring system consisting of various sensors, a control system and equipment designed to contain water emissions. In MCBU, as a rule, elements of smaller diameters are used.
Manual assembly of the UKB uses precise drawings and detailed instructions.
For work you will need:
Chuck suspension rope;
Base for mounting in the form of a frame;
Winch and motor.
The scheme is implemented in the following way:
First, a collapsible bed is assembled. In a separate order, the parts of the percussion chuck and the thief are connected in order to remove the soil.
To make the soil loosening more productive, the jagged protrusions at the bottom of the glass are used. In the upper part it is necessary to make holes for fastening the rope.
The thief is necessary for cleaning the face. It can be homemade.
The electric drive device, in turn, will help to significantly save time, and the work, at the same time, will be more efficient. In general, the structure is a hollow square shape.
Its main elements are:
Frame;
Winch;
Boer;
Special drilling hoses;
Reducer;
Swivel that rotates the drill string.
All parts, the rack and the support are connected by welding, after which the electric motor and the platform are fixed, which will simultaneously move along the tunnel of the iron constructor. If it is decided that a hydraulic piling machine will be used for drilling, you can make a hydraulic gearbox yourself.
The swivel provides the rotary motion that keeps the drill running.
By its structure, it consists of simple elements:
A body that can be made from thick-walled pipe scraps;
Metal rod;
2 baffles for O-rings;
Flanges - top and bottom.
The fixture uses an O-ring and ball bearings.
If you know how to use a lathe and you have a diagram, you can make a unit for the MCBU yourself.
For do-it-yourself manufacturing, some features of the operation of the mechanism should be taken into account:
Materials, including steel for homemade execution, must be selected with high weldability;
Since the device is subject to rapid wear, materials with resistance to mechanical and abrasion should be used for the housing.
Otherwise, you must strictly follow the installation diagram.
VIDEO Drilling equipment for various needs is used everywhere, but as the most demanded models for autonomous operation, compact modifications of the MCBU continue to be in the first place. This is understandable - they are mobile, convenient for use, do not require the involvement of a large number of service personnel, and, moreover, are highly efficient.
Drilling rigs differ in their design due to the choice of different methods for creating a well. For example, a percussion drill destroys the soil with a special weight tied to a pyramidal support frame. But a rotating drill is a much more complex structure, but it is much easier to make a deepening of the required size in the soil with its help. By type of construction, it can be divided into several categories:
Shock rope installations. The design is represented by a frame with a pyramidal base, to which a cable with a projectile (bailer) is securely attached. The principle of operation of such an installation is simple to the banal: the load is lowered and raised as many times as it takes to create a hole of the required depth in the soil.
Auger installations. Drilling is carried out using a screw that breaks through the ground according to the principle of rotation. In this case, the recess dug during the drilling process is not washed out.
Attention! Keep in mind that drilling rigs of this type are too complex to be created with your own hands: most of its functional elements are almost impossible to create in the absence of the appropriate skills and tools.
Rotors. Rotary structures work on the principle of hydraulics.
Rotary-type hand constructions. These installations are considered to be the simplest to a greater extent for the reason that they do not have an engine in their design. Accordingly, the process of creating a well in the soil is carried out manually, which requires considerable physical costs. That is why such manual designs are very rarely used.
Undoubtedly, a water well drilling rig has a number of advantages. These include:
Acceptable cost. It is noted that the factory design for drilling a water well in most cases is much more expensive than the one that was made by hand.
Compactness and low weight of the structure.
The technical characteristics of the hand-made drill, as it turned out, are in no way inferior to the factory-made units.
Ease of installation. Homemade drilling rigs are very easy to mount and dismantle.
In general, the assembly technology for various drilling rigs is practically the same (and this will be discussed a little later), but the working tool for different types of structures is fundamentally different. Therefore, first you should consider the technology of manufacturing the main mechanism (drill) for different structures and only after that proceed directly to creating the main frame and the working elements attached to it.
So, let us consider in detail the most frequently used drilling rigs (installation with a "glass" and auger installation).
Drilling rig with "chuck" uses the so-called "cartridge" ("glass") as the main working mechanism. If you want to make it yourself, then you only need a piece of pipe with a diameter of about 1 m. When creating a suitable base frame for such a drilling rig, the dimensions of the "cartridge" are taken into account without fail. The "cartridge" itself must have not only impressive dimensions, but also considerable weight for effective soil drilling.
If you do not want to make the edges of the "chuck" triangular, make sure that they are sharp (sharpen them if necessary).
We will fix the "glass" with a cable, so it is necessary to make several holes on the load (in the upper part). We attach the cable and then hook it to the previously prepared frame. Please note that the length of the cable must be such that the "cartridge" can fall down and rise up completely freely.
Auger installation uses a drill as an operating mechanism. An ordinary metal pipe is also quite suitable for its manufacture. Make a screw thread on the top of the pipe, and a screw-type auger on the bottom (the most convenient drill length is about 2 m).
Advice. 2-3 turns on the drill will be enough to create a water well of medium depth.
A pair of knives must be attached to the ends of the drill using a welding machine: they must be positioned so that during the drilling process they plunge into the soil at a certain angle.
To make the structure easy to use, weld a part of a metal pipe (about 1.5-2 m long) to the tee. The tee itself must be equipped with a screw thread inside.
Separately, it should be said about the swivel, which is used in drilling rigs as a compensator for the opposition of the moving part of the rig (drill) and the fixed part that supplies water.The device of this part is quite simple: a pair of flanges, partitions with rubber sealing rings, the body itself (made from a piece of metal pipe) and a metal bar.
It should be noted that you can make this part yourself only if you have turning experience and the ability to make technical drawings.
So, the working mechanism of the drilling rig is ready, now you can proceed directly to the assembly of the entire structure. Please note that you will need some tools for work: an electric drill, a grinder, a welding machine, as well as a galvanized pipe, a squeegee and a plumbing cross. Consider the process of assembling a structure step by step:
Preparing pipe sections to create the base of the drilling rig. They will need to be fastened to the squeegee and cross. At the ends of the pipe sections, cut the threads a couple of centimeters deep.
Weld pre-sharpened metal plates to the ends of the metal segments (such an installation will allow a continuous supply of water).
To supply water to the installation, connect a pump hose to one of the cross sections.
We connect the prepared parts to the threaded connections. We weld a metal segment with a tip to the bottom of the main pipe.
We are starting to assemble the base of the installation from a square profile. We connect metal supports to the main post by welding.
We attach the engine and platform to the profile. The profile itself must be attached to the main post in such a way that it moves freely along it.
The motor power will be regulated by means of a gearbox, to the shaft of which a flange must be attached. We attach another one to it, and between the flanges we lay a rubber washer.
The last step is to check the water supply. It should run smoothly.
This concludes our review of the technology for creating a home drilling rig for water supply. Good luck!
