RETAINER

Made from a steel circle, which allows you to install a furniture jig for drilling holes at the required distance from the edge of the processed chipboard. The movement step is ten millimeters.

Drawing

Let's say we want to install a furniture hinge:

1. We lay the template on the facade.
2.
3. We drill a hole with a diameter of three millimeters for the fixing screws of the cup to the desired depth.
4. We drill a hole with a diameter of three millimeters to the desired depth for further processing. The prepared hole will be the guide center for milling the hole for the flange of the furniture hinge with a diameter of thirty-five millimeters.
5. We lay the template on the body.
6. We drill a hole with a diameter of three millimeters to the desired depth for the fixing screws of the striker.

Let's say we want to install an eccentric coupler:

1. We lay the template on the horizontal surface of the chipboard part.
2. Install the latch in the hole.
3. We drill a hole with a diameter of three millimeters to the desired depth for further processing. The prepared hole will be the guide center for milling the hole for the eccentric of the furniture tie with a diameter of fifteen-five millimeters.
4. From the end of the chipboard, along one center line, we drill a through hole with a diameter of eight millimeters to the required depth

In the picture shown

AT different colors shows the center on the furniture conductor for various technological operations.

Sometimes at home you need to make holes in blanks for wood, metal, chipboard or other material.

Swivel

Bushings are provided on the body of the device, which regulate the axes of rotation in the horizontal, vertical and inclined planes. These models of conductors are designed for drilling cylindrical products.

sliding

The name speaks for itself, the conductor is not attached in any way, it is simply applied where a hole needs to be made.

Tiltable

Able to make holes in several planes.

Stationary

They do not have rotary elements, they are able to move the part and process the same type of workpiece.

Universal

These conductors have such a function as readjustment. This allows small enterprises to quickly and conveniently switch to the production of a new product.

Description of conductors

Let's start with the concept of conductor- this is the so-called template, the use of which allows for comfortable and ultra-precise drilling.

Moreover, drilling can be both perpendicular to the surface, and at any angle. If you use a conductor, then you do not need special qualifications, do complex calculations, make markings where there will be holes, which saves a lot of time.

Applications

As we can see, due to the versatility and simplicity of their design, conductors are widely used in different areas activities.

mechanical engineering

In the mechanical engineering industry, they are used to drill holes in various workpieces made from common materials. Conductors are used that repeat the drawing with exact observance of all dimensions. It is also used when drilling of mixed type holes is required.

Furniture manufacturing

Conductors received the most important distribution in furniture production. Furniture conductors are used to install fittings, assemble furniture and many other technological processes.

At the same time, furniture assembly is neat, accurate and fast. A large amount of furniture contains dowels, which must be installed very accurately and here without a conductor there is nowhere.

The most common jig for dowels is doweling. They mainly use overhead conductors made of lightweight materials.

Construction

Another area in which conductors are widely used for drilling holes is construction. With their help, drilling of technological holes in building structures, for example, .

Main benefits of using

You can buy a conductor or make your own.

But before choosing a model, you should decide for what tasks it will be used, and based on all this data, you should choose the type and design of the tool.

So why should you use jigs for drilling holes:

  1. Intuitive use that does not require professional skills.
  2. The low price of the device, as well as the possibility self-manufacturing.
  3. Saves a lot of time.
  4. On the surface to be treated, it is not required to apply markings with.
  5. Drilling precision.

A jig for drilling holes is an integral part of not only production, but it will also be useful in home life.

How to make a conductor with your own hands

Since there are many types of conductors, we will consider original design and analogue, respectively. So, let's begin.

Jig for perpendicular drilling

Its main purpose is to obtain holes in thick workpieces at an angle of 90. In fact, it is a set of bushings combined in one body. Usually these are overhead conductors, which are widely used in the assembly of furniture.

It is worth attaching the device to the surface and you can immediately start drilling, without punching. There is one minus, the device should be held tightly, and especially at the beginning of work. Because from vibration, the fixture can move.

This type of conductors, you can do it yourself.

  1. As a basis, you can use a wooden block, a piece of textolite, reinforcement with a square section of 10x10 mm.
  2. We process the surface well, clean it and proceed to the marking.
  3. It should be noted that the center of the holes should be located at 8 mm. from the edge of the workpiece. This is due to the fact that 8 mm. this is half the thickness of the sheet.
  4. According to the standards, there should be exactly 32 mm between the centers of the holes.
  5. After that, in these centers we make holes with a diameter of 5 mm.

A home-made jig can be used, but for more convenient use, an emphasis should be designed; for this, metal with a width of 23-25 ​​mm is used. and 1 mm thick, after which the sheet is bent at an angle of 90 and attached to the conductor. Also, bushings of different diameters can be inserted into the base of the conductor.

Jig for pipes and cylindrical blanks

Everyone knows that making a hole in a sloping surface is problematic, the end of the drill constantly jumps off. This type of conductors is fixed in a predetermined position and allows you to work with high accuracy.

This type of conductors can be done quickly and independently.

  1. To do this, we need a bar of hardwood, loosened diagonally. And we attach a piece of plywood to the edge of the bar using self-tapping screws.
  2. Then we make holes of the desired diameter in a wooden bar.

That's all the conductor is ready to go. In order for the holes to break less, they can be reinforced with metal sleeves, which are made from round pipes of different diameters.

Angle drilling jig

This type of drilling is rarely used.

It should be noted here that in metal products this type of hole is made only with a cutter. As for wooden products, there are turnkey solutions in the form of kits.

It is easy to use these conductors, we press the workpiece tightly to the base, set the given height and as a result we get even and beautiful oblique holes at an angle. Yes, if we do not need a through hole, then it is unforgettable to put a stop ring on the drill itself.

On your own this species devices are difficult and problematic to manufacture. Is there enough simple ways and variants, but they do not differ in accuracy. So, for example, a drill is placed on a prepared inclined surface and our workpiece is drilled at the angle obtained, as we understand the accuracy suffers greatly.

Jig for drilling holes for dowels

Their main purpose is to maintain the alignment of the holes, in the future, into which dowels will be installed. That is, when you apply the jig to both sides of the product, you get the perfect joint.

As you understand, this type of conductors can be made independently. If you have a stream of workpieces with the same geometry, it will be convenient for you to use an invoice template. It is desirable to use hardboard or other transparent material (plastic) as a template.

We mark and drill holes. It is advisable to hammer brass or copper tubes into the holes so that the drill does not break the calibration hole.

Universal fixture

When you use blanks various forms and sizes, you will need a universal fixture. The most interesting thing is that this device can be made from improvised materials.

  1. For this we need plywood, about 15 mm thick.
  2. We make three identical blanks.
  3. Along the edges we make holes into which dowels are installed as legs.
  4. We make one hole in the middle, which we reinforce with a metal tube.
  5. We make three metal strips with symmetrically arranged holes, they will serve as a shoulder. These shoulders are responsible for the linearity of the holes of the future conductor.
  6. We make cuts in plywood blanks and install metal shoulders, we fix everything. Our universal self-centering jig is ready.

Conclusion

Any universal hole drilling jig is made to save time and money. And you make it yourself or buy it ready-made in the store, it's up to you.

The jig for drilling holes greatly facilitates the work of furniture makers and other professionals who, by the nature of their activities, have to make precise holes in wood, chipboard, MDF, metal and other materials.

What kind of conductors are there and is it possible to make this device with your own hands - the main issues that the article is devoted to.

Basic information about conductors

Conductors - simple devices, a kind of templates that have been successfully used in mechanical engineering for a long time.

They allow you to make a hole in the right place and at a strictly defined angle. The scope of conductors is very wide, from drilling machines to diamond drilling installations.

Today, every furniture master has in his arsenal a set of these tools that allow you to assemble furniture cases, install fittings and perform other operations.

Conductors are needed in construction (for example, to make holes in the wall of a building) and various industries.

As a rule, only overhead models are used here, which are made from lightweight materials to facilitate the work of the master.

The furniture conductor can be factory-made or hand-made.

Many craftsmen have such a trained eye and precise hand that it is not at all difficult for them to drill holes at the right angle without additional tools. However, this requires vast experience and, perhaps, talent.

With the help of the tool to which this article is devoted, even a novice furniture maker will be able to make precise holes for dowels and assemble cabinet furniture without complex preliminary calculations and markings. This reduces the labor intensity and, therefore, the cost of the work and speeds up the process.

Before you buy or make a conductor, you need to decide on the varieties and purpose.

Overhead conductors are named so due to the fact that they are superimposed on the workpiece with which to work. They are either fixed on the part, or simply held by hand.

With the help of overhead tools, for example, holes are made in MDF boards.

Swivel jigs are needed if you need holes on the surface of the cylinder. Inclined, vertical and horizontal axis of rotation allow you to drill holes at different angles.

Unified conductors are especially in demand in small-scale production, where it is necessary to drill many holes in the same type of parts of various sizes.

This is possible due to the ability to readjust the tool for a different size of the part.

The scope of tilting conductors is the need to make holes in several planes.

The sliding conductor does not need to be fixed on the surface of the machine - it is attached to the specific surface in which it is necessary to drill a hole.

It is more convenient to work with fixed models, but sliding ones give the master a certain freedom of action when working on a single-spindle drilling machine, especially if several holes are needed on one surface.

Something about the scope

Drilling jig is included in the list necessary tools for furniture assembly. One of the difficulties when making any holes is that the drill can enter the drilled material at the wrong angle.

It can take a lot of effort and time to correct the situation, in addition, not all errors can be corrected.

The conductor serves not only as a template, thanks to which the master understands where to drill, but also guides the drill, preventing it from deviating from the given direction.

First of all, the tool is necessary for specialists who produce furniture, but it is not uncommon during assembly when a finished furniture set does not have the necessary holes, for example, for dowels.

The jig is indispensable for drilling thin slabs, such as chipboard, for making holes at an angle and many other operations.

Precise, simple, fast assembly of furniture always takes place with the participation of this tool. With it, you can make a hole at any distance from the edge of the part, regardless of its width.

One of the operations in which you cannot do without a conductor is the installation of dowels.

By and large, dowels are the last century, in modern furniture production they already use other types of fasteners to connect various parts of cabinet furniture. However, the connection with the help of dowels is still quite widely used.

The main difficulty in mounting them lies precisely in the accuracy of the location of the holes, and in a strictly perpendicular direction, so that you can connect the parts at an angle of 90 °.

If even one hole is in the wrong place or at the wrong angle, this will lead to errors that are quite difficult to correct. A special tool is called a jig for drilling under dowels (doweling jig).

Furniture is a common, but not the only scope for drilling tools. The second important direction is the drilling of pipes and other cylindrical blanks. Conductors allow you to drill even pipes of small diameter.

If collect different kinds templates for drilling on the same workbench, it turns out that they are very different in appearance and size.

Some are easier to buy factory-made, especially if making tools is not your hobby, others can be made by hand without much difficulty.

Multifunctional conductors from well-known manufacturers are not cheap - assembling them yourself, you can save a lot.

Conductors of own production

The simplest tools are inexpensive, so many craftsmen find it easier to buy them. However, there are enthusiasts for whom tool making is of particular interest.

In addition, with your own hands you can make a really durable tool that will faithfully last for many years.

Another reason to make your own tool is if you need a template for custom holes.

There are a large number of drawings and video instructions on the Internet for making do-it-yourself drilling jigs.

This requires a set of tools:

  • drill;
  • angle grinder (grinder);
  • standard set of locksmith tools;
  • welding machine - not necessary in all cases, but for making the most complex tools with your own hands, it may be required.

Another argument "for" the independent manufacture of conductors - each master will surely have the necessary blanks for their manufacture: wooden blocks, pieces of reinforcement, metal plates.

The jig-template for precise marking and drilling of holes on it is so simple that even a novice master can make it.

Take a rebar with a square section of 10 x 10 mm (or larger) - the required length must be cut with a hacksaw or a grinder.

Sections are preferably prepared with a file and sandpaper. This is the basis of the future conductor.

Now you need to mark the holes. One of them should be at a distance of 8 mm from the edge of the jig - at this distance is the central part of the chipboard board.

Furniture standards dictate the pitch between the holes - it is 32 mm. According to this marking, it is necessary to drill holes with a diameter of 5 mm.

The conductor is almost ready for use, but if you equip it with an emphasis, then it will be much more convenient to assemble furniture.

It is made from a metal plate 1 mm thick and 25 mm wide. The workpiece for the stop must be bent at a right angle and fixed in the clamp together with the finished part made of reinforcement.

Now you need to make holes for the thread and fasten the two parts together with bolts.

Furniture conductor can be equipped with half plastic bottle so that drilling holes is not so dusty. From the same plastic bottle, you can build a small pallet for collecting chips.

This is the simplest jig for drilling holes, thanks to which the assembly of cabinet furniture will become much easier.

With it, you don’t have to worry that the drill may enter the chipboard crookedly or drill through it.

In the process of assembling or repairing furniture, it is often necessary to perform work on precise drilling of holes for confirmation, for dowels, dowels and other furniture fasteners. In the case of wood and chipboard, it is difficult to make such holes using only an electric drill: the entrance part of the hole is broken, and it itself may not turn out at right angles to the mating surfaces. Thus, a jig is required for drilling holes.

Purpose and classification of furniture conductors

The purpose of the jig for drilling holes is to accurately direct the drill to the required point, and ensure the straightness of the tool throughout the entire depth of the hole being made. In metalworking, such devices have been known for a long time, and are often supplied with the machine. Due to the increased number of closed connections in modern furniture products, the need for such conductors for woodworking specialists is very relevant.

There are the following varieties furniture conductors:

  1. Overlays that do not require fixing before use. They are simple, mobile, but they force you to use only one hand when drilling (if the drill or grinder is not installed in a special frame). Making such a conductor with your own hands is easy and simple. They are mainly used when making holes in MDF or chipboard.
  2. Swivel, which are equipped with folding brackets, and allow you to perform drilling on two planes adjacent to each other with one go.
  3. Conductors for drilling holes at an angle. A highly specialized version of the conductor, which is designed to make holes at various angles. Often combined with the overhead design of the equipment in question.
  4. Sliding, with which you can make several holes without changing the settings (including in several rows). More necessary for professionals who often have to perform such work. Requires skill to use correctly.

With sufficient rigidity of the conductor, it can also be used for drilling holes in products that do not have a flat plane, for example, in pipes. Then the conductor is fixed with a clamp (this option is not suitable for furniture, because of the danger of surface deformation).

Jig for drilling holes with your own hands

Basically, such equipment consists of the following parts:

  1. An angular body element applied to the surfaces of products, which will subsequently be connected to each other with dowels, dowels or confirmations.
  2. Guide bushings, which includes a drill.
  3. Clamping / fixing devices, which are located at the end parts of the conductor.

For the conductor, who is supposed to be made by hand, it is important to design a fixture for the most common home master fastening options. If you need a universal conductor (for furniture makers), then it is better to spend money on an industrial version of the equipment, which is characterized by increased accuracy of fixing parts, and has a better performance. Moreover, manufacturers often offer templates, stops and other useful little things in the kit for the jig. Furniture conductor price industrial production ranges from 500 to 1200 rubles, which is determined by its functionality– length and number of guide holes.

Let's start designing a furniture jig for drilling holes by choosing a corner. More opportunities for the product, where the corner will be unequal, and with the maximum possible thickness of the shelf. According to the GOST 8510 range “Steel unequal angles”, the minimum allowable dimensions are the L63 × 40 × 8 angle: with a shelf thickness of 8 mm, a guide sleeve with an outer diameter of up to 6 mm can be placed there. The inner hole for the drill, therefore, can be no more than 3.5 ... 4 mm, but this is quite enough for most options for the holes to be obtained. In extreme cases, they can be drilled out without using the fixture, especially if the hole is deep enough.

The next step is the design of the guide bushing. It can be selected from any stainless pipe GOST 9941 (seamless) or GOST 9940 (all-welded). It is recommended that you first select the pipe according to the diameter of the inner hole. A 6×1 pipe will make it possible to obtain an internal hole for a drill with a diameter of up to 3.6 ... 3.7 mm, and a 6×1.5 pipe - for a drill up to 2.7 mm (double-sided clearance is taken taking into account the thermal expansion of the material). The length of the sleeve must be no less than twice the height of the hole made in the corner. The landing of each bushing in the hole must be carried out with an interference fit or transition. The most appropriate is the fit on the shaft system, when the already known outer diameter of the sleeve is taken as the basis, and a hole is drilled under it in the corner. It is better to use a slight interference fit, such as h9/P10.


It happens that the conductor must be calculated for drilling a deep hole. In such cases, the sleeve must be stepped (with a collar). Bushings for machine tools according to GOST 12214 have the necessary accuracy and dimensions, the inner hole in which has a constant diameter value along the entire height of the bushing.

The number of holes, and especially the distance between them, is chosen according to the specific needs of the user.

When choosing a mounting method for the conductor, choose one of the following options:

  • Spring stop, which will press the surface of the conductor to the part due to the elastic forces of the material. Any flat spring with the required clamping force is suitable as such an emphasis;
  • Fixing with self-tapping screws, which are screwed into the material of the part, and keep the jig from being displaced by friction forces. This option is convenient in that the resulting outlines can be further used as additional elements for centering the future hole. In the case of chipboard, this option should be used with caution;
  • External clamps, under which it is worth placing corrugated rubber gaskets. In this case, the weight of the conductor will increase, and the compliance of the rubber may violate the perpendicularity of the axis of the conductor bushings. Therefore, using this method of fastening, the drill is first inserted into the sleeve, the hole is marked, and only after that the clamp is used.

Drilling jig for dowels and dowels

The sequence and design of the simplest devices for accurately obtaining holes is considered in the following two examples:

  1. Multi-position conductor with clamp fastening (see Fig. 1). A thick-walled aluminum corner is adopted here as the initial body part. Due to the considerable length of the device, an intermediate fastening is provided in the middle. When turning the jig at an angle of 90º, the increased thickness of the wall of the corner, which is superimposed on the surface of the part, is successfully used. The distance between the guide bushings is selected according to the most common distances for dowels or for confirmation.

Figure 1 - Multi-position jig for drilling holes with clamp fastening

  1. Two-slider furniture jig, with which you can make holes in two mutually mating parts. The design of the device is clear from the attached drawing (see Fig. 2). It consists of two guide lines, which are connected by fasteners to the connecting bar. The presence of several holes on it allows you to install the bar on parts of various widths. Interchangeable housings with a set of guide bushings with different distances between them move along the rulers. Fixation of the conductor is carried out using connecting strip, and on the opposite side - a stroke limiter, which is pressed with a wing screw.

Figure 2 - Multi-slider furniture jig: 1 - Guide ruler; 2 - Adjusting screw; 3 - Housing; 4 - Thrust bar; 5- Movement limiter.

A jig for drilling holes with your own hands will not be a reliable solution, but it will be beneficial in financial plan. If possible, it is better to buy it in special shops for furniture making tools.

According to the statistics of furniture manufacturers, most of the time is taken by marking, harvesting and making holes. For this reason, the furniture assembly jig becomes a very important element.

The importance of using conductors

In order not to resort to manual measurements and sketches, a special device was invented - a jig for drilling holes. Its use allows you to hold the drill at an angle of 90 degrees to the furniture, which eliminates deviations from the required direction. When making deep holes, the result of using this device becomes especially noticeable.

A jig for drilling holes in high quality chipboard must have the following qualities:

  • be useful for fast furniture assembly without the use of complex tools;
  • provide the ability to simultaneously make several holes, excluding manual marking;
  • improve drilling quality.

The material for the jig for drilling holes is different. Among tools made of plastic or organic glass, the steel version stands out.

It has such advantages as:

  • less susceptibility to deformation;
  • exact direction of the drill;
  • does not heat up during operation.

Very popular among home craftsmen is the conductor for assembling furniture with their own hands. To make it at home, you need a small number of tools.

Experts recommend fixing this device with the help of dowels. In the manufacture wooden furniture only these elements are allowed to be used together with glue. In any case, a home-made jig for drilling holes is very useful in practice, and without it it will be difficult to carry out assembly work.

The process of drilling holes for conformation and dowels looks quite laborious. The quality of its implementation will depend on the reliability and appearance manufactured furniture.

A do-it-yourself furniture jig for drilling holes will help improve the quality of the holes made. Without their use, errors in manual marking cannot be avoided.

There are many different conductors from various manufacturers. Among them, there are such specialized options as a jig for drilling holes at an angle. Not less than interesting option can become a jig for drilling end holes.

All this diversity makes it possible to simplify many complex operations that may occur in the manufacture of furniture. With their use, marking and drilling holes of any complexity on doors, on tiles, when assembling furniture can become a very simple task.

However, tools of this level are quite expensive, which causes the popular question: “How to make a jig for drilling holes yourself?”. It's easy to do and almost anyone can do it.

The process of self-manufacturing conductors for drilling

In principle, the jig for the holes can be made from improvised materials. First you need to calculate the folding conductor for drilling holes with your own hands. The next step is to work on the drawing. A furniture jig template for drilling holes can help solve this problem. You can find one on the Internet or from repair specialists.

A detailed description of all stages of manufacturing furniture conductors can be found on special videos on the Internet. But still important point it remains to make the correct drawing of the conductor for assembling furniture. In each case, it can be different and you need to take into account all the features.

Do-it-yourself jig drawings for drilling holes may not have the required accuracy. For this reason, there is a need for additional verification during the manufacture itself. It is also important to be extremely accurate and accurate, otherwise the manufactured tool will not bring any benefit and can only aggravate the process of furniture production.

The variety is very large, so you can hear the following question from novice furniture makers: "How to make a jig for drilling pocket holes with your own hands." One of the secrets in the manufacture can be the use of metal bushings. This approach will extend the life of the conductor and make it a more reliable tool.
