Jig for drilling holes in wood. Jig for drilling holes with your own hands. Purchased or homemade: which is better

25.10.2019

Precise drilling used to connect wooden, metal and other elements to each other is a guarantee that the product will be of high quality, without backlash, durable and will be effectively used for a long time. In the case of 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 bar. It has several holes, inside of which there are special bushings - sleeves.

Templates can be made in different options, but the task is the same for everyone - marking for drilling

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

determine the place of drilling;
we apply a conductor to it;
fix the fixture convenient way;
put sleeves in the holes;
drill in the indicated places.

Marker classification

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

Overhead jig for drilling holes

Attachment jig with turret is suitable for drilling standard holes for dowels of any size

The group is called this way because of the way they operate. It is customary to install the product on top of the intended workpiece and fix it with screw clamps. Less often at home, it is based on an emphasis on any plane. So you can mark the holes for furniture screws.

Swivel jig for drilling holes

Use such a jig for drilling at an angle. Comfortable processing is obtained due to the guide bushings.

Tiltable jig for drilling holes

Tilting to work on multiple surfaces

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

Sliding jig for drilling holes

Demanded in those areas where it is not possible to fix the marker. The guide bushings are attached to the folding strips.

Not only conductors are widely used for drilling holes for confirming, but templates are also used in mechanical engineering when you need to make many drills of the same type in blanks.

This device has many advantages:

achieve maximum accuracy in finished goods;
ease of operation;
the ability to repeat the center distance on any surfaces at a convenient time;
affordable cost of the finished product;
you can make a homemade jig for any workpiece and different center distances.

Scope of application

During the furniture assembly process, some drawings indicate the places for drilling holes, inside which the pins will be located. In such a situation, you can not do without a precise tool. It will not be possible to combine the interfaces on the parts to be joined as clearly as possible with a simple marking, so a furniture jig for drilling holes is useful.

Even a simple fixture in the form of a bar with an emphasis greatly facilitates and speeds up the process of making holes of the same type.

In addition, the template engine contributes to the rapid detection of the desired points after the marker is based. In addition to holes for dowels, recesses are needed for mounting door hinges. They can also be done with a hard stencil.

Marking and drilling many holes at an angle or perpendicular, 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. It will also be possible to save time and get the desired result thanks to the conductor. You can supplement the set of accessories with an installation that ensures the 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. Someone chooses to do it with my own hands so that the product has the necessary functionality and is suitable for a specific job. Other specialists strive to choose the most comfortable product from the products offered in online stores.

When buying, 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 items, and for daily operations it is worth getting a professional product.

Do-it-yourself production does not take much time. Also suitable materials always at hand.

Homemade device

It must be borne in mind that this device includes a certain number of parts:

body corner element, which must be applied alternately to blanks 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 workpieces due to screw or cam connections.

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

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

Designing begins with the choice of a corner, which will serve as the base blank. It is preferable to choose a base with different sides, as well as the greatest possible thickness of the metal. According to GOST 8510, products with side parameters of 63x40 mm and 8 mm thick will be the most acceptable. With such overall values, it will be possible to use bushings 6 mm long, and there remains an internal space for a drill of no more than 4 mm in diameter.

In most cases, these values \u200b\u200bare 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.

It is worth starting the choice with the selection of a tube according to the internal section. The 6x1 mm format is usually used, which makes it easy to use a drill with a diameter of 3.6-3.7 mm. It is important to observe the rule that the minimum length of the sleeve can be twice the outer diameter of the tube.

The landing of the sleeve is performed with a slight interference fit or in a transitional format. It is reasonable to perform it in the shaft system, because the stable outer diameter of the tube will serve as the basis. It is under it that voids are drilled in the corner. It is worth using h9/P10 fit.

In some cases, a marker is required to make sufficiently deep holes. This technique implies the presence of a stepped sleeve with collars. Strict GOST 12214 defines the parameters for machine conductors.

How many sockets to drill and how to arrange them, the owner of the tool determines 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 due to the elastic material;
on self-tapping screws, you can firmly fix the conductor, but when working with chipboard and similar materials, you should refrain from this method;
external clamps, under which for safety reasons there are rubberized gaskets.

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

With the help of a conductor, production is greatly accelerated, the work of the worker is facilitated.

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

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

With this equipment, the manufacturer is relieved of the following problems:

Markup.
Punching (point recesses in the material for the drill).
Drilling with observance of perpendicularity.

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

Some operations, such as dowel drilling (short wooden rods designed for concealed joining of parts), require very precise marking, and no less precise 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

Overhead. They do not need fixing before their intended use. Structurally simple, mobile, but they need to be kept free from the drill by hand, since often the equipment is not fixed in a special device, which is not very convenient. Given the simplicity of the design, making it yourself is quite simple. It is used when drilling chipboard and MDF.

Conductors for drilling holes at an angle. The design is easy to imagine as the name speaks for itself. Such equipment can also be consignment note. In the production of high-quality furniture, there is also drilling at an angle, which is not the easiest operation in manufacturing process- it takes skill. Although in this case, the desired angle is sometimes violated, the assembly as a result will no longer be of such high quality and suffer appearance furniture, especially if it is not made of chipboard, but of wood - here you can’t putty on ugly drilling. The equipment of the 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, without reinstallation, you can drill several holes. To work with such equipment, however, the necessary skills are required.

Device for drilling holes for dowels and confirmations

Despite the fact that today a lot of new fittings have appeared in the furniture industry, the good old dowel is still used. This is due to the fact that the joints are not visible through this piece of fittings, and this is especially valuable in the production of natural wood furniture.

As already mentioned, dowel drilling creates a lot of problems for furniture makers, especially those who are not qualified enough.

In order for the furniture planes to be perfectly joined, accurate marking is necessary, and this equipment allows you to speed up the work and bring the quality to the desired level.

Working with confirmations - special furniture screws - although less troublesome, but also requires certain skills. And given how many holes you need to mark and drill before screwing the confirmation in one piece of furniture, such a device will greatly speed up the work, and its quality too.

The simplest devices

The conductor is two-slider. It allows you to drill holes in two adjacent (mating) parts. The fixture is constructed from two rulers that serve as guides and are connected to the mounting plate. The holes made in it make it possible to install a bar on parts of different widths. Housings moved along the 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, on the opposite side there is a travel limiter, which is pressed with a thumb screw.
The conductor is multiposition. Attaches with clamps. The design allows for vertical drilling. It is made from thick-walled aluminium. Since the fixture has a significant length, it is equipped with an intermediate mount in the center of the structure. The thick wall of the corner was very successfully applied, which cannot be overestimated at the moment of applying the fixture to the surface of the part and when reinstalling the conductor by 90 °. The selection of the distance between the bushings is carried out according to the most common values \u200b\u200bfor the installation of dowels or confirmations.

How to work with a conductor:

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

Do-it-yourself furniture conductor: drawings with dimensions to help

Principle of this equipment:

Corner case. It is superimposed on the plane of the parts, which will then be connected to each other.
Guide bushings. A drill will enter through them.
Clamping devices. They fix the conductor and are made from the end part.

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

Important! If you need a universal assistant - this applies to professional furniture makers, then it would be better to purchase industrial equipment, which is made more accurately and efficiently. It is such a 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 a lot of different templates, stops and other little things that are also necessary in the work. They are much cheaper than buying at retail.

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

Such equipment, perhaps, is needed not so often in a particular production, and even more so for a home master. So for many users, doing it yourself will be much more profitable.

If the design of such remains relevant, then it is necessary to prepare materials for the manufacture homemade conductor for drilling under confirmation:

Corner. You should stop your choice on the unequal type of this rental - its possibilities are wider. The corner shelf must be chosen with the greatest thickness, which can reach up to 8 mm. This is well justified, since then guide bushings with an outer diameter of up to 6 mm can be inserted. Based on this, drills from 3.5 to 4 mm can be used. Even if that diameter is not enough, then the material is drilled with a large drill, without using any other devices.
Guide bushings. Here it will be preferable to use stainless steel pipes, which are selected, first of all, according to the inner diameter. Example: a 6×1.5 pipe is suitable for a drill no larger than 2.7 in diameter. Explanation: its inner hole will be 3 mm, and a small gap along the entire inner diameter is taken into account due to the thermal expansion of the material. The sleeve length 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 - such are available, for example, in mechanical engineering. Such parts (even used ones) will come in handy: they are made of alloyed steels and have an almost unlimited service life.

Choice of 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.
The emphasis is spring. It will securely fix the conductor on the part. For such an emphasis, a flat spring with an appropriate clamping force is suitable.
Clamps external. Under them it is necessary to lay rubber gaskets. Corrugated rubber is ideal as a material. This, of course, slightly increases the weight of the tool, and the elasticity of the pads can negatively affect the squareness of the bushings. To prevent this from happening, the drill is inserted into the sleeve in order to mark the hole, and only then the clamps are clamped.

For drilling pipes and cylindrical parts

AT modern furniture not only chipboard, fiberboard, MDF and wood are used. As additional elements may apply steel pipes different diameter. Covered with chrome or stainless steel, they perfectly complement the overall furniture ensemble.

It is very difficult to drill a spherical surface - the drill strives to slip to the side. Yes, and marking is not so easy when there are a lot of holes and they are arranged in several rows.

In order for the notorious colander to turn out of the pipe, but the correct part with precisely made holes, you will need a jig - this is the ideal solution in this situation.

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

Without being able to make such a device, you can use waste materials, making an even simpler device using a bar and a strip of plywood. So, a bar cut diagonally lengthwise into circular saw, can be nailed or screwed with screws at an angle of 90 ° to plywood. The resulting device is superimposed on top of the pipe, and a strip of plywood, resting against a table or workbench, does not allow the specified angle to be violated. Holes of the required diameter pre-drilled in the bar are 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.

Do-it-yourself furniture conductors and templates

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

Not only conductors, but also templates are necessary in furniture production. The simplest template will sometimes save a lot of time and enable no less accurate drilling 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 interconnected by screws in the upper part of the structure - this is how they are attached to the square. The square is drilled under 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 at all. And the price of this equipment is below any idea of \u200b\u200bsavings.

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

Materials:

Plywood.
Textolite or fiberglass - preferably thick.
Hard wood.
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 summarizing what has been said. Making a jig or a template yourself or buying it in a store is up to each individual. If a home craftsman needs to make some kind of furniture in a single copy and there is material for the conductor, as well as the possibility of manufacturing it, you can use this. It is possible that such equipment will never be useful to the master again.

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

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

Good luck in your work!

A jig for drilling holes is a device used in mechanical engineering to simplify the process of processing a part. In fact, it is a template that serves to guide or position the workpiece. It can be used on various equipment, such as, for example, or a diamond drilling machine.

AT engineering production conductors are fairly accurate fixtures (up to 0.05 mm (depending on the requirements for the manufactured part)). They come in two main types: overhead (in the form of plates) and box-shaped, which are three-dimensional structures. There are also conductors for drilling of mixed type. These devices are used to reduce labor intensity: from technological process machining of the part, the marking operation is removed, in addition, it becomes possible to drill several holes at the same time.

The drilling jig is used only in serial and mass production. This is due to the fact that for a small batch of parts it is impractical to manufacture a separate fixture, which, moreover, will have to be installed and configured separately.

A drilling jig is usually used to process several holes that lie in the same plane. It is best if the parts are unified in terms of standard sizes, this will allow the device to be used for a wide range of products.

The drilling jig is also used in light industry and construction. Such devices are only of the overhead type, made of or lighter materials, such as wood or plexiglass. These products are not designed for high accuracy, the positioning error is only ±0.5 mm. But this is more than enough to make holes for fittings in furniture or drill a series of holes in the wall of the house. Used as equipment conventional drill or a benchtop drilling machine.

You can make your own conductor for household needs. It will be needed during repairs, when you need to make a lot of holes of the same type and there is no desire to spend time on preliminary marking. For its manufacture, you can use any materials at hand: on a sheet of metal or a wooden board, outline and drill all the necessary holes that will serve as guides. If necessary, a plumb line is additionally made so that chips or concrete chips do not fall to the floor. It is possible to make a dust-free jig when the template is covered with a specially fitted half of a plastic bottle.

The main advantages of these devices are high accuracy positioning holes without pre-marking, high labor productivity and reduced perpendicularity deviation (due to guide bushings). However, the use of a drilling jig is not always economically justified, especially with small batches of parts in production.

When creating furniture, almost all the details have to be joined end-to-end. This is done with the help of dowels in which holes are made. This is where a special detail is needed. You can buy it or make a furniture conductor with your own hands.

What is a furniture conductor

The conductor is a bar that has several holes and sleeves. It is applied to the desired part, the drill is inserted into the sleeve and a hole is made. To fix two parts, you will need the help of one conductor, while the parts are fixed as securely as possible.

Conductor Benefits:

precise drilling;
simple and fast creation of holes.

At the same time, conductors are used not only during construction, but also in mechanical engineering. Also, this device allows you to drill cylindrical blanks and pipes.

Different types of conductors

Depending on the industry, conductors are divided as follows:

Overhead. They got their name because of the scope. This device is superimposed on the workpiece and fixed, with the help of which holes are made.
Swivel. They are used to drill cylindrical holes. In this case, the rotary axes can be located both horizontally and vertically, and at an angle. The housing here is equipped with swivel bushings.
Overturned. They are used when holes are created in several planes.
Sliding. Used to make each individual hole. In this case, this model is not fixed on the surface, which means that it is not the most convenient.

Do-it-yourself furniture conductor

As we wrote above, this product is needed when assembling furniture. Someone prefers to buy it, and someone to make furniture holes with their own hands. Such products are sold in any hardware stores, it is important to choose finished products for a specific purpose. The cost of a furniture conductor will depend on its size, purpose and manufacturer.

The simplest option is inexpensive, but professional equipment with various additional functions costs a lot. Therefore, today they are increasingly doing furniture conductors and handmade templates.

They are produced using a metal sheet or wooden board. They make holes that will serve as guides. This job is easy and anyone can do it.

How to create a conductor

So, creating a furniture conductor with your own hands is not difficult. To get started you will need:

welding machine;
Bulgarian;
drill and some locksmith tools;
you also need to prepare reinforcement 10 x 10 mm in advance.

First, the workpiece is cleaned with sandpaper and marking is performed. The distance from center to center is approximately 32 mm. Next, each template hole is drilled. After that, an emphasis is created - for this you can take a metal plate 1 mm thick. It needs to be bent and a place for carving prepared. The last step is the connection of these parts.

The product must be made as accurately and accurately as possible, otherwise there will be no benefit from it, and in an unfavorable situation, it can even damage furniture. You can learn more about how to make a conductor by watching various video tutorials. The easiest way to make it is according to a furniture template, which can also be peeped from specialists.

In order for drilling not to cause complications, a conductor is needed. This device is really needed when assembling furniture. Of course, you can buy everything today, but it’s better to make a furniture conductor with your own hands, because then such equipment is exactly right for each specific purpose.

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