Jig for drilling holes: how to use and how to make it yourself? Drilling jig: application Device for drilling holes in chipboard

Make maximum and accurate holes in products based on natural wood, metal, MDF or chipboard can be done using a special conductor. This is an indispensable thing for those who produce furniture; such a device is also needed in other areas.

Such a conductor can be purchased ready-made, or you can make it yourself.

Features of application in the furniture industry

Conductors and templates are needed when assembling furniture. With these things, you will prevent a common problem that occurs during drilling - the drill hitting the part at the wrong angle. Correcting such an error will take an extremely long time, in some cases it will even be impossible.

A jig for making holes will not only allow you to correctly orient the working tool, but will also prevent it from straying from the desired trajectory.

In the furniture industry, conductors and templates are used in the following cases:

When using such a device, the assembly process will be much easier and faster, required holes you can do this no matter how far they need to be from the edge of the part or how wide it is.

At self-assembly Furniture often has to be joined end-to-end using dowels. Holes for dowels are best made using a special jig. The peculiarity of dowels is that despite the fact that such fasteners, although outdated, are still relevant in furniture production.

The difficulty in their use lies in the fact that the axes of the holes that are made in the parts when connecting must have a right angle with each other. Accordingly, they must be placed strictly perpendicular to each other. It is difficult to do this without a special device. Therefore, if you want to achieve high quality execution, it is recommended to buy a dowel jig.

Other uses

Hole jigs are used not only in furniture production. Quite often they are used when you need to make a hole in a pipe or other part. cylindrical. Thanks to them, you can make a high-quality hole even in a pipe with a small diameter.

Such devices are universal and easy to use, so they are also used in the following industries:

• mechanical engineering - drilling holes in different-sized workpieces based on different materials;
• construction - drilling holes in building structures;
• home communications - as already mentioned, pipe drilling and more.

Modern drilling jigs can be different sizes and have different operating principles. Some of them are complex, so they are easier to buy. And some modifications can be made independently, especially since some serial furniture models, especially those with universal purposes, are expensive.

Benefits of use

Essentially, such a jig acts as a template for making holes so that they are made as accurately as possible. They can be used for those holes whose axis is perpendicular to the surface workpiece, and also for working at an angle.

This tool - great alternative sketches and manual measurements. You can place the drill strictly at the desired angle in relation to the workpiece and will not allow any deviation. The result will be especially noticeable when it comes to making deep holes.

If you use such a high-quality device for working with chipboard, then it should have the following characteristics:

• promote quick assembly furniture without the need to use complex instruments;
• make it possible to make several holes simultaneously without manual marking;
• significantly improve the quality of work with the drill.

Conductors are made from different materials; there are models based on plastic or organic glass. However, the best option is considered to be steel., which has such advantages as:

• minimal likelihood of deformation;
• the drill is directed as clearly as possible;
• no heating during operation.

Very often, overhead models based on lightweight materials that are easy to manipulate are used as furniture jigs. Many people use factory or homemade tools.

And most qualified and experienced craftsmen They no longer use a jig because they can easily make a hole in structures on their own as accurately as possible. But not everyone can do this.

The key advantage of such a device is that the work can be performed as accurately and efficiently as possible, even by a person who does not have the proper experience. You don't have to do markings and complex preliminary calculations. You will save a lot of time and produce furniture much faster.

Classification of tools

Before you buy a ready-made conductor or make it yourself, you need to decide what problems you will solve with its help and only then you need to select suitable option in design and function.

DIY jig for drilling holes

As already mentioned, depending on the scope of use and design, you can make some options yourself, thanks to which you will save a significant amount.

Before work, find the required device drawing and make everything strictly according to it.

Tools required for work:

• welding machine;
• Bulgarian;
• drill;
• locksmith supplies.

To make the simplest version of the conductor with your own hands, we perform the following steps:

As you can see, such a device is very simple to make yourself, but it will greatly simplify your work if you are making furniture. If you are doing this purely as an amateur, then this option will be sufficient. If you can't make it yourself, buy ready-made option, perhaps the simplest and most inexpensive.

But professional equipment will cost much more, the feasibility of purchasing it already exists when we are talking about at least small-scale mass production. But with its help you can easily and quickly connect pieces of furniture or repair it.

So, you have learned what a hole-punching jig is and how it helps in furniture production. This device can be purchased at finished form, do it yourself.

This allows you to accurately and efficiently make holes in products made from natural wood, chipboard, MDF, metal and other materials. convenient device as a conductor. This device, in particular, is actively used by specialists involved in the production of furniture. At the same time, the conductor can either be purchased in a serial version or made with your own hands.

Design features and types

A jig, in essence, is a template for drilling holes, allowing you to make them as accurately as possible. It is used both to create holes, the axis of which is perpendicular to the surface of the part, and for drilling at an angle.

Due to their versatility and simplicity, drilling jigs are widely used in various fields. In particular, in the mechanical engineering industry they have long been used to successfully drill holes in workpieces of various configurations and made of different materials. You cannot work without a conductor and in furniture production, where such a device is actively used when assembling furniture, installing fittings on it and performing a number of other technological operations. Construction is another area where conductors find wide application. They are used, in particular, to drill holes in building structures. Conductors are also needed for drilling pipes and solving other tasks.

As furniture jigs, overhead models made of lightweight materials are most often used to make them easier to manipulate. You can purchase such devices factory-made or make them furniture conductor with your own hands. Qualified furniture makers may not use a jig to accurately and accurately drill holes in furniture structural elements, but to do this they must have extensive experience in their field.

The most significant advantage of the conductor is that with its help high-quality and precision drilling both perpendicular to the surface of the part and inclined hole Even a person who is not highly qualified can perform it. The use of conductors eliminates the need for complex preliminary calculations and marking the locations of future holes, which reduces the labor intensity of assembling a furniture structure and allows such work to be completed in a shorter period of time. Even a novice specialist can understand the use of a jig for drilling for dowels and solving other technological problems.

Before purchasing or making your own homemade jig, determine what tasks you need to use it for, and based on this data, select its type and design.

Among the jigs for drilling holes, according to the type of design and functionality, we can distinguish a whole series categories.

Invoices

These jigs are so called because they are placed on the workpiece and secured to it or simply fixed by hand. Using jigs of this type, in particular, they drill holes in chipboards, MDF boards and other flat parts.

Rotary

Such templates can be used to make holes on cylindrical parts. Conductors of this type are equipped with vertical and horizontal axes of rotation, which makes it possible to make holes at different angles with their help.

Universal

These are devices that are especially relevant for small batch production, where the ability to quickly change over the equipment used is important. This type of conductor is endowed with just such functions.

Tiltable

These devices for drilling holes are required in cases where such a technological operation has to be performed in several planes.

Sliding and pinning

The sliding jig, in full accordance with its name, does not require fastening: it is simply applied to the area of ​​the surface of the part where the hole needs to be drilled. Fixed jig devices, although more convenient, somewhat limit the freedom of action of the specialist, which is especially critical when performing drilling work on machines equipped with only one spindle.

Areas of use

Furniture jigs and templates are devices that are practically indispensable during assembly. furniture designs. The use of jigs allows you to avoid the main problem that arises when drilling holes - the drill entering the workpiece at the wrong angle. Correcting this error takes a lot of time and effort, and it is not always possible to fix it at all. The jig used for drilling holes not only allows you to correctly orient the drill at the processing site, but also prevents the tool from straying from the specified trajectory.

Devices such as furniture jigs and templates are used both in the production and assembly of furniture, when holes must be made in the elements being connected to accommodate fasteners. In such cases, a jig for dowels or a jig for drilling for confirmation is often used, without which quality holes for fastening is not possible. Such a device is indispensable in cases where it is necessary to make holes, including at an angle, in thin slabs (in particular, when making holes in chipboard or MDF).

When using a jig to drill holes, the process of assembling furniture is simple and fast. Using such a device, holes can be drilled at any distance from the edge of the part, regardless of its width.

IN modern furniture Dowels are actively used, which at the same time are a rather outdated fastening element. That is why the doweling jig is used in the production of furniture structures. The main difficulty when using such fasteners is that the axes of the holes made in the parts being connected have a right angle to each other. Accordingly, such holes should be located strictly perpendicular to each other. Without the use of such a device as a dowel jig, it is difficult to perform them.

Furniture production is not the only area in which jigs designed for drilling holes are used. Templates are no less often used to drill a hole in a pipe and other cylindrical parts. Conductors allow you to make high-quality holes even in small-diameter pipes.

The size and operating principle of modern conductors may vary. Some of the models of such devices are much easier to buy, and some are easy to make with your own hands. The fact that serial devices, especially those for universal use, are not cheap, also speaks in favor of making a furniture jig for drilling holes with your own hands.

Homemade conductor devices

Conductors simplest design, for example, those that are used for drilling holes for confirmation are relatively inexpensive, so many craftsmen do not bother making them themselves and purchase serial models. Meanwhile, there are those who are even like this simple devices trying to do it with his own hands. The question of how to make a jig for drilling with your own hands often arises and, if necessary, drill non-standard holes.

To make your own jig for dowels or a simpler design jig for confirmations, you can use drawings and videos on the Internet.

To manufacture such a device, naturally, you will need a drawing of it. Also needed minimum set tools and equipment:

• electric or hand drill;
• a set of locksmith tools;
• Bulgarian;
• welding machine (for the manufacture of jig devices of a more complex design).

The simplest homemade conductor can be made from available tools and materials that are available in abundance in most home workshops or garages. The use of such materials, which include pieces of metal reinforcement, wooden blocks, metal plates, etc., allows you to significantly save on the purchase production model devices.

Manufacturing self-made conductor for a drill or single-spindle machine takes place in several stages.

1. Square reinforcement with a cross section of 10 by 10 mm, using a hacksaw or grinder, must be cut into pieces of the required length.
2. The centers of the holes through which drilling will be performed should be at a distance of 8 mm from the edge of the conductor plate. It is at this distance that the center is located chipboards or MDF in which a hole is drilled.
3. The pitch between the holes on the jig, in accordance with generally accepted furniture standards, is 32 mm, while the diameter of such holes should be 5 mm.
4. If you equip a homemade conductor with a stop, then using such a device will be much more convenient. To create such a stop, you need a metal plate 1 mm thick and 25 mm wide, which is bent at a right angle and fixed to a ready-made jig device made from reinforcement.
5. After structural elements homemade conductor are fixed with a clamp, they must be securely connected to each other using threaded fasteners.

Precision drilling, used to connect wooden, metal and other elements to each other, is the key to the fact that the product will be of high quality, without backlash, durable and will be used effectively long time. When processing chipboard, OSB, MDF and other materials, it is recommended to use a drilling jig to achieve successful results.

Need for an assistive device

A do-it-yourself drilling jig helps both at home and during industrial processing. This product is a thick metal strip. It has several holes, inside of which there are special bushings - sleeves.

Template makers can be manufactured in different options, but everyone has the same task - marking for drilling

A step-by-step algorithm that involves using a jig to drill holes in workpieces consists of the following steps:

• determine the drilling location;
• apply a conductor to it;
• fix the device in a convenient way;
• We put sleeves in the holes;
• drill in the indicated places.

Classification of markers

A jig for drilling holes with your own hands is used in different areas production activities. Based on similar characteristics, similar auxiliary devices are usually divided into several groups:

Jig for drilling holes

An overhead jig with a turret head is suitable for drilling standard holes for dowels of any size

The group is called this way because of the way it is operated. The product is usually installed on top of the intended workpiece and fixed using screw clamps. Less often, at home, it is based on an emphasis on any plane. This way you can mark holes for furniture screws.

Rotary jig for drilling holes

This jig is used for drilling at an angle. Comfortable processing is achieved due to guide bushings.

Tilting jig for drilling holes

Tiltable for use on multiple surfaces

The group is involved in drilling on several surfaces located at an angle to each other.

Sliding jig for drilling holes

They are in demand in areas where it is not possible to fix the marker. The guide bushings are mounted on folding bars.

Not only jigs are widely used for drilling holes for confirmation, but templates are also used in mechanical engineering, when it is necessary to make many of the same type of drills in workpieces.

This device has many advantages:

• achieves maximum accuracy in finished products;
• ease of operation;
• the ability to repeat the center distance on any surface at a convenient time;
• affordable cost of the finished product;
• You can make a homemade jig for any workpieces and different center distances.

Scope of application

During the furniture assembly process, some drawings indicate where to drill holes where the pins will be located inside. In such a situation, you cannot do without an accurate tool. It will not be possible to align the mates on the parts being connected as clearly as possible with simple markings, so a furniture jig will be useful for drilling holes.

Even a simple device in the form of a strip with a stop greatly facilitates and speeds up the process of making holes of the same type

In addition, the templating engine facilitates quick detection of the required points after the marker is located. In addition to holes for dowels, cavities for installation are also needed door hinges. They can also be made using a rigid stencil.

Marking and drilling multiple holes at an angle or perpendicularly, at the end or on the main surface in a pipe without help is always problematic. This is due to the special geometry of the workpiece. You can also save time and get the desired result thanks to the conductor. The set of auxiliary devices can be supplemented with an installation that ensures perpendicularity of the drill entry.

The difference between store-bought and homemade

The importance of this equipment, which performs an auxiliary function, cannot be overestimated. Some people prefer to do it with my own hands so that the product has the necessary functionality and is suitable for a specific job. Other experts strive to choose the most comfortable product from the products offered in online stores.

When purchasing, you need to pay attention to the manufacturer. The final price tag depends on the capabilities of the template. At home, it is enough to use household units, but for daily operations it is worth acquiring a professional product.

Making it yourself doesn't take much time. Also suitable materials always at hand.

Homemade device

It must be taken into account that this device includes a certain number of parts:

• body corner element, which must be applied one by one to the workpieces intended for connection with dowels or self-tapping screws;
• guide bushings-sleeves through which the drill will pass during the drilling process;
• clamps that provide a strong connection between the tool and the workpiece through a screw or cam connection.

A homemade template should include drawings and markings that are most often found at home on furniture and other areas. You will need to stock up on special stops to help with the work. The average cost of finished samples will be about 500-1000 rubles. The difference between them is the dimensions, functionality and the number of guide bushings.

Assembly drawing of a homemade marker

How to make a jig for drilling holes with your own hands

Design begins with choosing a corner that will serve as a base blank. It is preferable to choose a base with different sides, as well as the greatest possible metal thickness. According to GOST 8510, the most acceptable products will be those with side parameters of 63x40 mm and 8 mm thick. With such overall dimensions, it will be possible to use bushings 6 mm long, but all that remains is interior space for a drill no more than 4 mm in diameter.

In most cases, these values ​​are enough to make your own template with your own hands. Additionally, you will need bushings, which at home are usually cut from stainless steel, corresponding to GOST 9941 or GOST 9940 for seamless and all-welded pipes, respectively.

The choice should begin by selecting the tube according to its internal cross-section. Usually the 6x1 mm format is used, which makes it easy to use a drill of 3.6-3.7 mm in diameter. It is important to follow the rule that the minimum sleeve length can be doubled O.D. tubes.

The liner is seated with a slight interference fit or in a transitional format. It makes sense to do it in a shaft system, because the basis will be a stable outer diameter of the tube. It is for this that the voids in the corner are drilled. It is worth using the h9/P10 fit.

In some cases, a scriber is required to make sufficiently deep holes. This technique involves the presence of a stepped sleeve with collars. Strict GOST 12214 determines the parameters for machine jigs.

How many sockets to drill and how to position them is determined by the owner of the tool independently according to his needs. Traditionally, one of the following mounting options is chosen:

• using a spring-loaded stop that presses the jig to the part thanks to the elastic material;
• You can firmly fix the conductor using self-tapping screws, but when working with chipboard and similar materials you should refrain from this method;
• external clamps, under which there are rubberized gaskets for safety reasons.

If you make furniture with your own hands, then you know that all products must be butt-joined. In this regard, there is a need to drill many holes. To do this, all craftsmen use a special tool. It's about about the jig for drilling holes.

What is it?

The jig is a plate on which holes and sleeves are located. Even a beginner can use such equipment. It only takes a few steps:

• the equipment is fixed in the right place;
• a drill is inserted into the sleeve;
• a hole is carefully made.

To fasten two parts you only need one jig.

Advantages

This device is used not only in the manufacture of furniture and construction, but also in mechanical engineering. It can be used to drill holes on any surface. There are several other advantages:

• highest accuracy;
• ease of use.

Variety

All models, regardless of their application, are to one degree or another divided into several main groups. Let's look at them in more detail:

• Invoices. They received this name due to their special use. Equipment is applied to the selected workpiece. Fixed or left without clamping. Ideal for use in materials such as chipboard.
• Rotary. If you need to make a passage on a cylindrical surface, then you should definitely use this type of equipment. This type has several rotation axes: vertical, horizontal, inclined. For the latter, the housing has a guide sleeve.
• Tiltable. If you need to drill simultaneously on several planes, then you should use this type of jigs.
• Sliding. The last group is not in demand, as it is considered the most inconvenient. Before drilling, it is necessary to bring the device into working position. This type cannot be fixed to the surface.

Application

Drilling jigs are used in many fields of activity. Most often in construction. But besides this, there are several other important industries.

Furniture

During assembly, many craftsmen are faced with a problem such as a lack of holes. In this case, you have to make new ones yourself. To do this easily, it is recommended to use a jig. With its help, all work will be done quickly, efficiently and accurately. Craftsmen who do not have a special machine should also resort to the help of such a device.

Modern assembly features a wide selection furniture fittings and various fasteners. All this requires precise installation without displacement. This is where the conductor will help.

Pipes

Make holes correct form on cylindrical surfaces quite difficult. Using a drill in this case is useless. It will constantly slide off, which means they will all turn out to be of irregular shape. For this, it is recommended to use a conductor.

Additionally, you can use devices with it that help you do perpendicular holes. It will also help to process rounded elements and edges.

Purchased or homemade: which is better?

When assembling furniture, the use of such a device is mandatory. Some people prefer to buy a ready-made version in a store, while many make them themselves.

As for sale, they can be found in almost every hardware store. However, it may turn out that the purchased equipment may not suit your needs.

The cost of products is influenced by the following factors:

• method of use;
• size range;
• manufacturer.

Simple equipment has a low cost, but products with additional functions will cost more.

Having a little idea about the conductor and some tools, you can make it yourself.

Self-production

To work you need to prepare following materials and tools:

• metal sheet or wooden board;
• welding machine;
• angle grinder;
• drill;
• screwdrivers;
• wire cutters;
• sandpaper;
• pliers;
• reinforcement measuring 10*10 mm.

• Make a preparation. It must be cleaned with sandpaper. Mark future holes. There is a standard for this that says the distance between centers should be 32mm.
• We carry out drilling.
• The next step is to make a support from a metal plate. Its thickness should be 1 mm. It needs to be bent and the place for the thread marked.
• Connect the two parts together.

Technical side

It is worth familiarizing yourself with several drilling techniques in detail.

Under confirmation

At self-production Confirmats are often used in furniture. For such drilling use special drills with a size of 4.5 mm. It is easily recognized by its additional head.

Face drill

This is the most difficult technique. The drill should be perpendicular to the end. In this case, the drill must be held firmly and level. It is very convenient to use special equipment.

Drilling in two parts at the same time

This is the most accurate and quick way. For this method, it is necessary to prepare special clamps (clamps). The fixation must be of high quality so that the parts do not wobble.

Drilling for dowels

To do this, use a drill approximately 8 mm in size. To prevent through holes on the part, it is necessary to install a special depth limiter. It is recommended to use the same drill for the end, and the depth should not exceed 20 mm.

Video

From the video you will learn how to properly use a jig for drilling holes in chipboard.

A drilling jig is an indispensable attribute in large-scale production, no matter what kind. Where there is a lot of drilling, it is really necessary, especially when production is serial or mass.

With the help of the conductor to a large extent production is accelerating, the worker’s work is made easier.

A drilling jig, as a rule, is a bar (plate) with holes and bushings (sleeves). Using a jig it is much easier, for example, to drill pipes.

As for furniture production, they are also used here, although relatively recently.

With the help of such equipment, the manufacturer is relieved of the following problems:

• Marking.
• Punching (point depressions in the material for a drill).
• Drilling while maintaining perpendicularity.

The latter is especially difficult to achieve, since it requires serious skills acquired only over the years.

Some operations, for example, drilling for dowels (short wooden rods designed for hidden joining of parts), require very precise markings, and no less precision drilling at an angle of 90°.

With such a device as a conductor, these tasks are solved easily and simply.

Types: choose the one you need

Invoices. They do not require fixation before being used for their intended purpose. Structurally simple, mobile, but they need to be held with a hand free from the drill, since often the equipment is not secured in a special device, which is not very convenient. Considering simplicity of design making it yourself is quite simple. Used when drilling chipboard and MDF.

Jigs for drilling holes at an angle. The design is easy to imagine, since the name speaks for itself. Such equipment can also be an overhead one. In production quality furniture There is also drilling at an angle, which is not the most simple operation V production process- this requires skill. Although in this case the required angle is sometimes violated, as a result the assembly will not be of such high quality and will suffer appearance furniture, especially if it is not made of chipboard, but of wood - here you won’t be able to fill in an unsightly drill. The equipment desired design completely eliminates unnecessary problems.

Rotary conductors. They have folding brackets, and this allows drilling on two adjacent planes.

Sliding gearboxes. With their help, you can drill several holes without reinstallation. To work with such equipment, the necessary skills are still required.

Device for drilling holes for dowels and confirmations

Despite the fact that today in the furniture industry there are many new fittings, the good old dowel is still used today. This is explained by the fact that the connections are not visible through this piece of fittings, and this is especially valuable in the production of furniture made from natural wood.

As already mentioned, drilling for dowels creates many problems for furniture makers, especially those who are not sufficiently qualified.

In order to furniture planes were perfectly joined, precise marking is necessary, and this equipment allows you to speed up the work and bring the quality to the required level.

Working with confirmats - special furniture screws - although less troublesome, also requires certain skills. And considering how many holes need to be marked and drilled before screwing the confirmation into one piece of furniture, such a device will significantly speed up the work, and its quality too.

The simplest devices

1. The conductor is two-slider. It allows you to drill holes in two adjacent (mating) parts. The device is constructed of two rulers, which serve as guides and are connected to a mounting strip. The holes made in it make it possible to install a bar on the parts different widths. Housings moved along rulers (replaceable) have a set of guide bushings, where the distances between them are different. The conductor is fixed by means of a connecting strip, with opposite side There is also a travel limiter, pressed by a thumbscrew.
2. The conductor is multi-position. Fastened with clamps. The design allows you to produce vertical drilling. It is made of thick-walled aluminum angle. Since the device is of considerable length, it is equipped intermediate fastening in the center of the structure. The thick wall of the angle was used very successfully, which cannot be overestimated at the moment of placing the device on the surface of the part and when reinstalling the jig to 90°. The selection of the distance between the bushings is carried out according to the most common values ​​​​provided for installing dowels or confirmations.

Procedure for working with a conductor:

• The device is fixed on the workpiece.
• The sleeve is inserted into the hole.
• Drill through the sleeve.

DIY furniture jig: drawings with dimensions to help

The principle of this equipment:

1. Angle type housing. It is superimposed on the planes of the parts, which will then be connected to each other.
2. Guide bushings. The drill will go through them.
3. Clamping devices. They fix the jig and are made from the end part.

Designing your own jig should be based on the fact that with the help of this equipment it is possible to do most of the work performed related to various types of fasteners.

Important! If you need a universal assistant - this applies to professional furniture makers, then it would be better to purchase industrial equipment that is made more accurately and with high quality. It is this kind of device that will be preferable and will quickly pay for itself, especially if you also take into account the fact that this device often comes with many different templates, stops and other little things that are also necessary in the work. They are much cheaper than when purchased at retail.

And yet this device, if necessary, can be made with your own hands.

Such equipment may not be needed very often in a given production, let alone home handyman- especially. So for many users it will be much more profitable to do it themselves.

If the design of such remains relevant, then you need to prepare materials for the manufacture of a homemade conductor for drilling for confirmation:

• Corner. Your choice should be made on the unequal type of this rental - its possibilities are wider. The corner shelf should be chosen with the greatest thickness, which can reach up to 8 mm. This is quite justified, since then it is possible to insert guide bushings with an outer diameter of up to 6 mm. Based on this, you can use drills from 3.5 to 4 mm. Even if that diameter is not enough, then the material is drilled out with a large drill, without using any other devices.
• Guide bushings. Here pipes from stainless steel, which are selected primarily according to internal diameter. Example: a 6x1.5 pipe is suitable for a drill no larger than 2.7 in diameter. Explanation: internal hole it will be 3 mm, and a small gap along the entire internal diameter is taken into account due to thermal expansion material. The length of the sleeve is the depth of the hole in the corner, multiplied by two or more. The fit of the bushings is either transitional, or with an interference fit, or according to the shaft system. The latter is the most appropriate.

Instead of pipes, of course, you can use ready-made bushings used in wire drawing machines - these are available, for example, in mechanical engineering. Such parts (even used ones) come in handy: they are made of alloy steel and have an almost unlimited service life.

Choosing a mounting method

Options:

• Fixation with self-tapping screws. They are screwed into the part, which prevents the device from moving due to friction. This is convenient because these marks will be needed for subsequent drilling of other holes.
• Spring stop. It will securely fix the jig to the part. For such a stop, a flat spring with an appropriate clamping force is suitable.
• External clamps. Rubber pads must be placed under them. Corrugated rubber is ideal as a material. This, of course, slightly increases the weight of the equipment, and the elasticity of the pads can negatively affect the perpendicularity of the bushings. To prevent this from happening, the drill is inserted into the sleeve to mark the hole, and only then the clamps are clamped.

For drilling pipes and cylindrical parts

Modern furniture uses not only chipboard, fibreboard, MDF and wood. As additional elements may be applied steel pipes various diameters. Covered with chrome or stainless steel, they perfectly complement the overall furniture ensemble.

It is very difficult to drill into a spherical surface - the drill tends to slide to the side. And it’s not so easy to mark when there are a lot of holes and they are located in several rows.

In order to ensure that the pipe does not turn out to be the notorious colander, but the correct part with precisely made holes, you will need a jig - this perfect solution in the current situation.

There are steel conductors made in the form of an adjustable clamp. This design feature allows pipes to be clamped into them different diameters and drill holes in them with high precision.

Not being able to make such a device, you can use waste materials, making an even simpler device using a block and a strip of plywood. Thus, a block cut diagonally lengthwise into circular saw, can be nailed or screwed with screws at an angle of 90° to the plywood. The resulting device is placed on top of the pipe, and a strip of plywood, resting against a table or workbench, prevents the specified angle from being violated. Pre-drilled holes in the bar required diameter placed taking into account the required distances between future holes, which will allow you to quickly and accurately drill the pipe exactly according to the drawings.

DIY furniture conductors and templates

How conductors are made is now clear, as is their necessity for furniture production.

Not only conductors, but also templates are needed in furniture production. The simplest template will sometimes save a lot of time and allow drilling to be no less accurate than a jig.

For example, the simplest metal prefabricated invoice template, consisting of two sheet blanks measuring 130×70 mm and a steel square with a cross-section of 20 mm. They are connected to each other with screws at the top of the structure - this is how they are attached to the square. The square is drilled for the bushings, where the latter are pressed. Such a device for drilling holes in the end of a part made of chipboard will make it possible to drill without thinking about marking and perpendicular drilling. And the price of this equipment is below any idea of ​​savings.

Instead of metal, you can and should use those materials that are inexpensive and easy to process.

Materials:

• Plywood.
• Textolite or fiberglass - preferably thick.
• Hardwood.
• Hardboard or its equivalent.

It must be borne in mind that these materials are short-lived, and so that the devices do not have to be made every day, it is quite reasonable to press metal tubes into them.

In conclusion, it is worth summing up what has been said. Making a conductor or template yourself or buying it in a store is a matter for everyone individually. If a home craftsman needs to make some furniture in a single copy and there is material for a conductor, as well as the possibility of making it, you can use this. It is possible that such equipment will never be useful to the master again.

But if even a small furniture workshop is engaged in the production of serial furniture, and enough people work in it, it is probably easier to purchase something ready-made, especially since these irreplaceable helpers They will need masters in several copies.

In the latter case, it makes sense to purchase more expensive, accurate and wear-resistant jigs instead of making homemade ones, which are less accurate and durable.

Good luck in your work!
