Features of choosing furniture glue

When starting to build a roof, many are interested in how to lengthen the rafters. To do this, short structural elements are usually connected to each other: rafters, beams, etc. - this is shown in the photo. It is rare to achieve bending rigidity in the places where the rafters join - usually there are plate hinges there. In order to solve this problem, the joint is made where the bending possibilities approach zero.

When using a plate hinge, the distance from it to the rafter support is calculated as 15% of the span length (rafter installation pitch), where the connection is located. Since the distance of the spans between the intermediate support and the mauerlat, ridge and intermediate supports is different, when joining the rafters, an equal, rather than equal-deflection scheme is used, which is used when joining purlins. As for how to join the rafters, it is important to ensure equal strength, and not create equal deflection. But in the ridge run, the main thing is to ensure equal deflection so that the roof ridge remains at the same height.

During construction hip roofs involve rafters directed towards the internal or external corners walls In this case, the rafter legs are called slanted rafters. They turn out to be longer than usual, and become a support for the short rafters of the slopes.

Ways to splice rafters:

• butt connection;
• oblique cut;
• lap joint.

When connecting end-to-end, in order for everything to be securely fastened, the joining ends of both rafters are cut off at right angles. To ensure that the junction of the rafters is not subject to deflection, the end of each element must be cut at an angle of exactly ninety degrees. The cut ends of the rafters are connected with a metal fastener or a board overlay and secured. In order to cover the junction of the rafters on both sides, overlays made of boards are used, for fastening which metal nails are used for the rafter system.

How to glue chipboard together?

They nail them in checkerboard pattern, in one.

If the bevel cut method is used, the touching ends of the rafters are cut at an angle of 45 degrees. Then the ends of the rafters are connected together and fastened in the middle with a bolt having a diameter of 12 or 14 millimeters.

As for how to build up rafters with an overlap, then wooden elements laid on top of each other with an overlap of a meter or more; the accuracy of the rafters’ cut is not necessary.

Then, as in the case of end-to-end rafter connections, nails are nailed over the entire area of ​​​​contact of the spliced ​​elements in a checkerboard pattern.

Instead of nails, you can also use studs, secured on both sides with washers and nuts. The elements of the rafter system must be connected in such a way that the minimum load is placed at the junction points. To connect the rafters to the Mauerlat, rafter brackets are used.

Rafter connection

Mating is a connection of parts in which they fully or partially fit into each other. The rafters are connected to the mauerlat or beams by cutting or using a tooth with a tenon, creating nodes.

The upper part of the rafter leg is laid on a ridge purlin with partial or complete connection with the other rafter leg. A simple rafter system assembled from boards turns out to be no less durable than one made using wooden beam and poles. The boards are built up or connected in a certain order, and in some cases their use turns out to be more advantageous compared to heavy timber, both in terms of versatility and economy.

The following examples can be given rafter systems from boards, as a roof structure with an attic, which can be insulated and converted into an attic. To increase the length of the legs, rafters are sometimes used, connected by two boards with a gap. The peculiarity of this design is that it is enough to attach single rafters in the lower part of the system, and paired elements in the upper part.

In this way you can save on building material, and assembling the rafters with each other and with the crossbar is easier. Liners made from scraps of legs are laid between the rafters so that the distance between them is no more than seven heights of the connected boards. In this case, the flexibility of the rafters paired between the liners is zero, and it can work as solid element. In this case, the length of the liners should be twice the height of the boards or more (read also: “What is the distance between the rafters, calculation method”).

There are two types of rafters made from boards: composite and paired.

Twin rafters

Paired rafters are made up of at least two boards, which are placed close to each other with their wide sides, leaving no gaps, and are stitched along the entire length with nails in a checkerboard pattern, one after another.

Lengthening of rafters from paired boards occurs by simultaneous joining of parts end-to-end and overlapping to the second rafter board, due to which not only the length of the element increases, but also its strength. When choosing rafters, you must pay attention to the fact that the distance between the joints of the joining boards is more than one meter and is located in a checkerboard pattern along the product. The hinge joints should not be opposite each other, and each joint should be protected by a solid board.

Sloping rafters are the longest elements of rafter systems, and the most the best material to create them is a paired rafter board.

How to splice timber along the length, watch the video:

Composite rafters

Elements such as composite rafters are never used as diagonal elements. To create them, two boards of the same length are laid on an edge and connected to each other with a liner (third board). Then three boards are nailed in two rows. The length of the liner must exceed twice the height of the board.

The installation pitch of the rafters between the liners should be less than the thickness of the boards being connected, multiplied by the number seven. The first liner should be at the beginning of the rafters - in this case rafter leg will be equal to the thickness of three boards.

The upper part of the rafter is made from one board; it is attached like a liner between the side boards with nails and mounted on a ridge beam.

There is nothing complicated about how to cut rafters. There are several ways to increase the length of the rafters. The main thing is to do everything correctly, taking into account the slightest nuances, so that the roof turns out strong and reliable, and truss structure for many years didn't need any repairs.

Recently, they have become increasingly popular in the manufacture of furniture. corner connections slab materials with a miter bevel. In this article, our friend and colleague Sergei Novikov will share the secrets of making such a non-standard joint. Unlike a joint with an acute angle, which, firstly, is quite traumatic, and secondly, it is itself susceptible to chipping and deformation with minimal impact, this option is free from the above-mentioned disadvantages.

So, first, using a tire, we file the mating edges at an angle of 45 degrees. In principle, this can be done with sawing machine, But plunge saw with a tire (2 passes) against laminated chipboard gives better results.

So, we get two parts with sharp corners, let's move on directly to connecting them.

To enhance the strength of the joint, we will need a lamellar router (I think we can get by with a regular one, but with special devices(so far there are only vague outlines in my head). These flat furniture dowels (slats) are inserted into the grooves selected by the slats.

They prevent the parts from moving during displacement, and also add strength to the final connection, significantly increasing the gluing surface.

We coat the mating surfaces with glue (any PVA-containing glue will do).

We connect the parts and clamp them with clamps until the glue dries completely. After removing the clamps, glue streaks remain on the corner - they do not need to be removed, because... Later they will fall off on their own.

The next step is to smooth the corner. It is carried out either with an angular cutter (45 degrees), or cylindrical cutter, but for this the router must have an angular base.

After cutting the corner, you get this trapezoidal profile. Now our task is to improve this corner. You can, of course, just paint it or stick on an edge, but the edge will not stick, and when painting you won’t be able to get a neat, flat surface.

The cut must be puttied. IN in this case Automotive putty with fiberglass is used (what was on hand), but it is better to use more homogeneous mixtures.

Degrease the surface to be putty. The solution for this should not contain water.

How to fix chipboard

Apply the composition with a spatula, rubbing it into the pores and leveling.

After final drying, we finally smooth the surface with a sanding block with fine sandpaper. Now let's paint it over. Cheap spray paint will work for this.

We glue to protect the surface of the cut edge masking tape and cover with paint 2-3 times. For additional durability and shine, we cover it with a layer of acrylic varnish.

Cut off any streaks of varnish remaining after it has completely dried. stationery knife. It seems nothing complicated, but the result is very interesting.

How to glue chipboard?

Viktor Kushnir (2003-04-24 11:31)

Will PVA work or do I need something stronger?

DiamondShark (2003-04-24 11:34)

Better than epoxy.
And even better in combination with mechanical fastening(screws, pins, etc.)

Pasha676 (2003-04-24 11:35)

Viktor Kushnir (2003-04-24 11:36)

Yes, it’s unfortunate, the leg of the table broke - a chipboard board, thickness - 1.8 cm. I would like to connect it so that the fastenings are not noticeable.

MsGuns (2003-04-24 12:00)

If the chipboard is “torn out” at the break point, then make an insert out of wood (preferably beech - it has a texture without knots and is quite hard), and screw the leg to it using fasteners (not glue) such as corners. Then paint both the metal and the wood or seal it with self-adhesive film “to match the texture” of the table. The insert itself can be glued to a carefully processed recess in Simple chipboard PVA is a fairly strong glue. But for chipboard, it’s generally better to use wood glue or epoxy (the latter is expensive and somewhat difficult to use without special tools)

Sha (2003-04-24 12:50)

My cabinetmaker uncle used to fill up chipboard holes like this.
I wet the pothole with water for better adhesion.
Mixed PVA with sawdust thicker than this one
covered the voids with porridge. Strength of the hardened mass
higher than the strength of the chipboard itself. So next time
It will break somewhere else.

MsGuns (2003-04-24 13:07)

>Sha © (24.04.03 12:50)

Absolutely true, but not for areas in which there is a fastener with a non-longitudinal load. For example, if a chipboard with a hinged door hinge is “worn out,” then this method is sufficient to repair it, because the load is almost longitudinal, i.e. the force acts almost perpendicularly chipboard surfaces or along the fastener (screw, bolt, nail). If, for example, a leg is attached to the slab, then the forces will be somewhat or completely in a different direction (to the sides). Here the filler will quickly “break”.
In any case, of course, first it is advisable to see the “object” itself, or at least its schematic drawing.

Agree

Viktor Kushnir (2003-04-24 14:08)

Scheme:
Given the leg!

In general, thank you! The table is already standing, as soon as it breaks I’ll write again.
Delphi craftsmen are the best carpenters! 😎

For some reason the drawing wasn’t quite successful, but I think clearly.

How to glue chipboard, or How to achieve thickness of a product part by saving on material

How to connect chipboard parts; veneering

Connecting parts made of particleboard (chipboard) causes certain difficulties. Since this material crumbles easily at the edges, carpentry tenon joints are unsuitable here, and to ensure a strong connection it is necessary to use additional parts made of wood or metal.

One of the methods for obtaining a strong and hermetically sealed non-separable connection of parts is based on the use of screws and epoxy glue.

Screws are screwed into the end of one of the parts to be connected at a distance of 30-50 mm from one another. For screws, holes are drilled in advance with a diameter 1-1.5 mm smaller than the diameter of the screw. The screw threads are lubricated before screwing epoxy glue. In the second part, holes are drilled in appropriate places of such a diameter and depth that the screw heads of the first part fit easily into them.

Now all that remains is to fill the holes in the second part with epoxy glue, liberally coat the joining surfaces with the same glue, fold and compress the parts, ensuring a right angle between them. Excess glue must be removed and the assembly should be kept for 24 hours at room temperature.

This method is convenient for making boxes (for example, for speaker systems) from polished chipboard, as well as from thick plywood or boards, since the method is simpler than the tenon method and does not violate the decorative integrity of the material.

Veneering is the gluing of a product or components of a wood product with veneer - thin slender sheets of valuable wood.

All rips, gouges, chips and dents on the plywood surface must be sealed with inserts using glue. The smallest of these defects can be filled with adhesive putty. After sealing, the surface must be leveled and sanded. To prevent cracks from forming in the veneer after gluing, it is necessary to seal (cover) all tenon joints and end surfaces while preparing the product using strips, stickers or “kerchiefs”.

For large veneered areas, choose veneer with a large pattern, for small ones - with a small one. The veneer is cut using a paper pattern using a sharpened shoemaker's knife using a metal ruler. The cut pieces are sanded on the inside with coarse sandpaper and the cracks are filled with adhesive putty. The prepared veneer, after aligning the edges, which should meet at the joints, is folded according to the dimensions of the veneered part, edge to edge, and glued with paper tape 20-25 mm wide. In order for the edges of the veneer to tighten, the paper is soaked in water before gluing, and after gluing, it is carefully smoothed.

Veneering is carried out in a room with an air temperature of 25-30°C.

The surface of the veneered part and inner side The veneer is lubricated with wood glue, and after 8-10 minutes the veneer is applied to the veneered surface and rubbed in with a smooth block or a flat carpenter's hammer. It is good to rub the veneer with an iron heated to 50-60 °C. Grinding should be done along the lines of the veneer texture from the middle to the edges. Bubbles that appear must be immediately eliminated, for which the veneer in the defective area is moistened with water, cut and glue is injected under it using a pipette or syringe, and then this area is smoothed with an iron.

Patches are applied to chips and tears, selected according to color and texture.

The dents are moistened and ironed with a hot iron until flat surface. After one and a half to two hours of drying at a temperature of 25-30 ° C, the paper strips with which the veneer pieces were connected should be removed.

Review of adhesive options for kitchen countertops

Chipboard table top

The modern furniture industry is gaining momentum. Many individual entrepreneurs try not to engage in manufacturing kitchen sets, but enter into contracts with the manufacturer and assemble ready-made modules. During the assembly process, there is a high probability of adjusting the tabletop in place and you have to resort to using glue.

In order to understand the diversity, we will conduct brief overview varieties adhesive edge and glue for various countertops.

Edge adhesive for laminated chipboard tabletops

This is the most common in furniture production material. During the cutting process, the edges of laminated chipboard require additional processing to give them an aesthetic appearance and protection from moisture. There are several types edge tape with an adhesive base, intended for finishing the ends of the tabletop:

1. PVC strips – form strong wear-resistant protection. Having an affordable price, they are resistant not only to moisture, but also to mechanical damage and aggressive environment. The material is elastic and easy to process. The disadvantages include a small temperature barrier from -5°C to +45°C, which leads to brittleness at low temperatures and melting at high temperatures.
2. Paper tape with melamine impregnation - short-lived, budget option. The outer surface of the edge is coated with varnish, the inner surface with adhesive. For gluing, just heat it with a hairdryer or iron. It has questionable protection against moisture; the edges wear out quickly during use. Advantages include flexibility and presentable appearance final product.
3. ABS plastic is a durable, reliable, strong material without any flaws. Although it is used very rarely due to its high cost, which is compensated many times over by its long service life.
4. Veneer is strips of thinly cut wood from various types of wood. Used in production. It has a high cost. Requires special equipment and operating skills. IN living conditions does not apply.
5. Acrylic edge or 3D - made of transparent acrylic with a printed pattern. The polymer layer gives the image volumetric view, which gave the film its name – “3D”. Has good performance characteristics and high cost. Used for decorative design countertops, as well as in individual orders.

Acrylic 3D edge

Laminated particle boards have different thicknesses, according to their dimensions and the edge with glue for the tabletop is selected. The most popular is PVC strip, which is available in the same colors as laminated chipboard.

Adhesive for artificial stone countertops

Gluing tabletops from artificial stone

Quartz composite is considered the most durable and strong material. From small crumbs natural stone and polymer resin, durable, wear-resistant countertops are made. They are resistant to moisture, high temperature and various aggressive substances.

Thanks to the application modern technologies the performance qualities of artificial and natural stone are equal. The beautiful appearance preserves the natural pattern of quartz. The surface is resistant to mechanical damage and ultraviolet rays. Long time retains its original shape and color.

For installation on a ready-made kitchen module, the worktops are supplied as a full-size slab, which is adjusted to the location and secured with adhesive. For reliable and high-quality gluing, use adhesive compositions based on acrylic base.

The main advantages of the acrylic component are:

Acrylic stone adhesive is widely used in restoration work. With its help, chips and small potholes are filled in stone slabs. After complete rise and polishing, these places become invisible and take on their original appearance.

Adhesive for artificial table top

Artificial countertop

Good strength and magnificent appearance of artificial stone were the reason for wide application it in the manufacture of countertops. However, they do not have sufficient strength and are susceptible to mechanical damage. To carry out restoration work, you will first need glue to repair artificial stone countertops.

Depending on the composition of the countertop, be it concrete, lime mortars or clay brick, a restoration adhesive mixture is selected. When choosing, first of all pay attention to the coloring. The color of the working surface and the glue must be identical, otherwise the restored stains will be obvious and the aesthetics of the countertop will be disrupted.

How to glue chipboard together and other materials

Diversity color palette adhesive composition will not make it difficult to choose.

Most adhesives intended for repairing artificial countertops contain white cement with polymer additives. They have good strength characteristics and high moisture resistance. White The mixture can be tinted well, therefore, you can easily select the desired tone. Restoration methods can be seen in the video.

To glue countertops made of artificial stone together, an adhesive consisting of two components is used: an acrylic-based polymer and a hardener. Before application, the components are mixed in a certain proportion indicated on the instructions for use. The main thing is that it is necessary to dilute not the entire volume, but only required quantity, since the unused mixture will quickly dry out and be unsuitable for further use.

When restoring furniture, you need to have not only high-quality parts, but also glue. The reliability of the design depends on this. Incorrectly selected products can ruin the appearance of the product and its functionality. The instructions do not always help you find out what material the glue is suitable for.

There are many types of glue, differing in color, consistency, and composition. There are suitable products for each material. If you select them correctly, the structure will be durable.

Selection rules

To purchase suitable glue for furniture, you need to consider simple rules:

• type of surface: usually it is written on the packaging what materials the product is intended for;
• type of coating base: furniture glue can hold all parts together efficiently, but the base is damaged, so you should choose a product based on synthetic elastomers;
• composition: there should not be trichloroethane, which is very harmful to human health;
• presence of solvent: the components are harmless to humans;
• color: usually the product is presented in white or yellow, so it must be selected to match your furniture;
• density of the product: you need to choose an indicator not lower than 1.1 g/cm 3, which will be enough for high-quality work.

Simple rules will help you acquire suitable remedy and quality repair of the product.

Types of glue

In addition to the rules for choosing glue, you need to pay attention to the type of product. This will allow you to do a high-quality job of fastening items. There are several types of furniture glue. PVA, or polyvinyl acetate, which is divided into 2 types: for home and repair garden furniture. The second type is moisture resistant, but since it has yellow, may leave marks.

Latex is perfect for repairing products made of different materials, for whom strength and safety are important. It has better penetrating ability, which is why it is chosen for the restoration of mechanically stressed furniture. There are no toxic substances in the composition.

For furniture it is intended for fastening plastic parts. You must work with the product carefully, since gluing occurs immediately. But since rubber is present in the composition, the glue does not harden.

To restore oily wood, you need the right furniture adhesive. Which one is better to use? Suitable for this The product is moisture resistant, therefore ideal for garden designs. After work, an invisible seam remains.

Polyurethane adhesive-sealant is used in fastening products with gaps. The product can be used to restore any furniture. The exposure duration is 1 minute. After this, the product should stand motionless for two days.

There is a two-component one used for different materials. The composition is useful for filling gaps, and the strength remains high quality. After the procedure, you can apply any film coatings and paint.

Preparing for work

In order for glue for chipboard furniture to have an excellent effect on the surface, you need to prepare everything necessary for the procedure. Parts must be clean. First you need to sand the surface, which will remove streaks of the old product.

Then you need to degrease the parts using a solvent. When the product is dry, glue for chipboard furniture is applied to it. It is advisable to decide in advance which one is better to choose. After drying, the furniture is ready for use.

What glue is suitable for wood?

If you prepare for the procedure and also choose the appropriate glue, the furniture will be repaired so that the gluing joints will not be visible. The following products are suitable:

• carpentry;
• synthetics;
• casein

Used in furniture repairs. But the product is quite susceptible to moisture. Even if you fasten the parts of a structure that will stand in the air, it will begin to collapse in frost. PVA also has the same disadvantages. The synthetic product is the most short-lived, since the surface is destroyed due to varnish.

European funds

Adhesives from foreign companies also deserve attention, since most of them are frost-resistant. Even if the structure is located in the air, you can work without problems. The composition is completely ready for use, and therefore there is no need to properly mix the components.

Such mixtures are moisture resistant, otherwise the moisture falling on the wood would not be able to dry properly. Mold gradually appears bad smell. European products are environmentally friendly, although they are not completely harmless. After drying, the parts are fastened securely.

Titebond glue

The products are manufactured by a popular American company. Furniture glue Titebond wood holds structures together perfectly. The company is constantly working to improve technology, so the range is regularly expanded.

The company produces glue on the following bases:

• alymphatic;
• polymer;
• polyurethane;
• protein;
• made of synthetic rubber;
• water.

Glue is used to create plywood, floor coverings, furniture. The manufacturer checks products for compliance with quality, strength, and moisture resistance. The carpentry product is suitable for furniture repair due to its moisture resistance and frost resistance.

The product consists of a polyaliphatic emulsion, so it is viscous and chemically resistant. He is not afraid of temperature changes, as well as other unfavorable factors. The benefits include:

• excellent adhesion to the surface;
• no long pressing required;
• high density;
• not abrasive;
• solvent resistant;
• easily removed before drying.

Caring for wooden furniture

After gluing wooden furniture needs care more than ever. Simple rules must be used. Even if high-quality glue is used, furniture should not be placed in the cold or exposed to sun rays. Humidity and temperature changes also have a negative effect.

There is no need to install structures near a balcony or window. To protect the product from sunlight, it is necessary to treat the surface varnish coating, and then wax. To prevent insects from infesting the wood, every summer you need to wipe the lower parts of the structure with a cloth with turpentine.

Furniture must be placed on a flat floor, otherwise deformation will appear over time. Cleaning should be done with a polishing cloth with a mixture of wax and antistatic agents. It will help to update the product vegetable oil, for example, burdock. You will need a few drops and a cloth.

In order for furniture to serve reliably for many years, restoration must be carried out with suitable tools and means. After this, you just need to follow simple maintenance rules, and then the structural parts will be fastened together with high quality.

Why did I bring up the topic (chipboard)? The one who does DIY furniture, wants not only to produce a high-quality product, but also to make it inexpensive. And by gluing two parts into one, you can achieve the required thickness of the part. At the same time, you can save on the cost of the stove.

Let me give you an example: there is a product that is mainly made of 16mm laminated chipboard, but several parts are 30mm thick. When ordering the cutting of such a product, we pay the cost of the entire slab, even if only a few parts are cut from it. In this case it is very uneconomical.

To save on the cost of material, you can make a part with a thickness of 30mm from 16mm laminated chipboard, gluing them together in double thickness. Please note that the part will be 32 mm, this must be taken into account. Although in some cases (if it is the lid of a chest of drawers or a cabinet), 2 mm does not play a special role.

FIRST METHOD

Task: get a 600x300 piece with a thickness of 32 or 36 mm, edged with a wide edge, by gluing two laminated chipboard details(16+16 or 18+18, etc. - the principle is the same).

To do this, you need to include two identical parts (!) in the cutting of 16mm chipboard. 620x320(i.e. increase the part from the required size by 10 cm around the perimeter).

If the thickened panel will be visible from both sides, we connect plane to plane using dowels and contact glue. The glue is applied evenly with a spatula thin layer for both parts. This must be done quickly, because contact glue dries quickly. We clamp it with clamps or under a press for at least 12 hours (I usually glue it today - tomorrow I’ll work on the part further).

If the thickened panel will only be visible from one side, you can, after gluing the parts (without dowels), fasten them with 4x30 screws along the edges and in the center. In this case, clamps or a press are not needed.

After gluing, “fit” the part into size 600x300, i.e., trim the edges around the perimeter. Do not forget to take into account the thickness of the edge in the dimensions of the part. The part must be cut on a machine, maintaining a clean cut and an angle of 90 degrees. Now you can trim it. Ready.

SECOND METHOD. Easier than the first one.

Task: get a 600x300 part with a thickness of 32 or 36 mm by gluing two edged chipboard parts (16+16 or 18+18, etc. - the principle is the same).

To do this, it is necessary to include two identical parts in the cutting of 16mm chipboard 600x300(!). Close them up.

Glue as in the previous method. Just need to align the edges more carefully! But the result is a little different - the part comes out thicker, but “double”.

Both methods of gluing chipboard are used in the project.

THIRD METHOD.

Task: obtain a part 600x300 with a thickness of 32 or 36 mm, using embedded chipboards of the appropriate thickness.

We include one part in the cutting 620x320(!) and mortgages - in this case 620x60- 2 pieces and 200x60- 2-3 pieces. The principle is to make mortgages around the perimeter and above the pillars, onto which the finished part will be attached.

We glue the part and the embedded parts contact glue and duplicate it with 4x30 screws. After complete drying, we “drive” it into size 600x300. And we edge the end.

In the case of a table top, mortgages are made around the perimeter and in the places where the legs will be attached, plus the bottom side is covered with 3mm fiberboard. We also glue fiberboard using contact adhesive and under a press. After complete drying, we “drive” it into the required size and edge the end. The result is a part with a thickness of 35 mm. Lightweight table top.

That's all I wanted to tell you. If you know other methods of gluing laminated chipboard, please share in the comments.

You've probably noticed that furniture assembled from a thicker laminate looks more solid; in addition, thicker parts are less likely to deform, which is especially important for countertops. But what if the slab of the required thickness is not on sale or you need only one part (for example, a table top) and buying a whole sheet for this is somehow unprofitable.

In such cases, they resort to fusion of laminated chipboards in thickness. The essence of the method is gluing two or more laminate sheets and subsequently covering them with a common edge.

For example, from 16 and 10 mm sheets you get 26 mm, from two 16 mm - 32. Please note that all sizes are standard (otherwise I once puzzled over why 32 and not 30)))

There are three main fusion techniques:

1. On self-tapping screws - used when one side of the resulting sheet will not be visible or the heads of the screws will be masked, for example, by shelves. With it, two sheets, previously coated with glue, are pulled together with self-tapping screws screwed into countersunk holes drilled on one side. Because in this case, a slight displacement is very likely, then the parts are sawn 3-5 mm larger than the required dimensions and, after the glue has dried, they are brought to the required dimensions and geometry with a milling cutter.

2. The second option is simple gluing blanks that are tightened with clamps. In this case, the workpieces are sawn “to size”, which means that attention should be paid special attention preventing their displacement relative to each other.

3. The third option is economical and is usually used for. With it, strips of laminate left after cutting are glued to the lower (invisible) part of the tabletop. This method, along with increasing the strength of the product, makes it possible to make maximum use of the laminated chipboard sheet.

After the glue has dried (and, if necessary, modified the geometry of the ends), select a groove for the edging, etc.
