How to make a beam profiling machine

Profiled timber is one of the most popular building materials. It is used for the construction of residential buildings, baths and other structures. Despite the apparent complexity, you can make a machine for profiling timber with your own hands. To do this, you should familiarize yourself with the principle of operation of the equipment.

Stages of manufacturing profiled timber

Machine for the manufacture of profiled timber

In the production process, a wooden blank goes through several stages of processing. The best option is to use a ready-made square or rectangular bar. Its surface is subjected to milling - finishing and the formation of mounting grooves.

The machine for the production of profiled timber consists of a support frame on which the workpiece is placed. A processing unit is installed in the upper part of the structure. It has an electric motor that drives the working shaft. Cutting knives are installed on it - from 2 to 4 pieces. Depending on their configuration, the workpiece is finely leveled or a recess (groove) is made on one side and a spike on the other.

In order to make a profiling machine with your own hands, you should decide on the design features of the main elements of the equipment:

• processing unit - mobile or stationary. For homemade designs, it is best to make it motionless. This will simplify the manufacturing process;
• number of processing shafts. In industrial models, their number varies from one to three. In the latter case, the possibility of complex processing of the workpiece from three sides appears. For do-it-yourself machines, the scheme with one working shaft is most often used.
• the possibility of installing cutting knives of various configurations. This eliminates the need to use several types of cutters. To perform the following operation, it will be enough to install other knives on the shaft.

In self-made designs, a manual workpiece feeding system is used. Guide rollers are located on the frame, along which the beam moves to the block of the workpiece.

To remove chips in the front part of the cutting block, an enclosing screen is made with a socket for connecting a forced air circulation system. This prevents waste from entering the working parts of the machine.

Cutting blade configuration

To draw up a diagram according to which a machine for beam profiling will be made, it is recommended to take the factory model as a basis. An important point is the choice of cutters or blades. The shape of the finished timber depends on their configuration. It is problematic to make them with your own hands, so it is best to buy ready-made models.

The profiling machine is most often made of frame type. For this, a welded structure is made of profile pipes of square section. Additional stiffening ribs will ensure its stability. Additionally, it is necessary to make clamping guides, which are needed to position the workpiece of various widths in the processing zone. These can be steel strips with the function of changing the position on the frame.

• processing block. The engine must be placed separately, the transmission of torque to the working shaft is carried out using a belt mechanism. The processing unit must be height adjustable. To do this, you can use hydraulic cylinders (increase positioning accuracy) or a worm gear;
• change of cutting knives on the shaft. This process should not take much time, so it is recommended to purchase a factory model of the shaft. This will improve the quality of processing;
• additional components. These include measuring rulers with which you can adjust the height of the processing unit and protective mechanisms that prevent overloading the electric motor. The latter is an important design element.

In addition, the main technical characteristics of the machine for the production of profiled timber should be taken into account:

• maximum and minimum dimensions of a wooden blank - width and height;
• the speed of material supply to the processing zone;
• working shaft width. This indicator affects the possibility of forming groove / tenon joints of various configurations;
• motor power.

An important factor is the dimensions and weight of the machine. They affect the minimum dimensions of the working room and the installation requirements of the installation. These figures are calculated in advance.

For example, you can watch a video that shows the operation of the factory model of the machine:

How to profile a beam yourself

Profiled timber is much more expensive than non-profiled timber. Can you save money by doing the missing steps yourself?

What are the advantages of do-it-yourself timber profiling:

1. Financial savings, and quite significant.
2. The profile can be made for specific needs (in particular, either reduce or make it impossible to blow through the house).
3. There is no need for facade decoration.

How to choose the final profile and the necessary equipment

First of all, we note that profiling a beam with your own hands will require a significant amount of time from the performer. Therefore, it is worth choosing the least labor-intensive profile in manufacturing, “adjusting” the frame of the future house for it. It is recommended to make profiling either “into a bar” or “triangle”, as in the photo.

To perform any of the options, you need special equipment. In particular, you will need a mobile woodworking milling machine with an appropriate set of cutters and a power of at least 1.5-2 kW. To improve the accuracy of an already completed profile, you can not do without a grinder. The disadvantage of this option is the high cost of equipment, which will most likely have to be rented. But it is possible to profile a beam with almost any of its cross sections.

If it is necessary to make a straight groove along the entire length, a circular saw is often used, which is cheaper and more common in the household. Profiling a straight groove with a circular saw is somewhat easier, since the depth of the groove (more often a “triangular” groove) can always be controlled. True, the time for profiling the beam will increase slightly, and it will be impossible to clean the finished groove. In addition, the characteristics of the saw itself should be clarified - it should allow the possibility of cutting a groove with a depth of 65 mm or more.

Ideally, the home master should have both a milling cutter and a circular saw.

Profiling Technology

When purchasing an unprofiled timber, you need to ask if the semi-finished product has undergone preliminary antifungal impregnation. If not, then after the final readiness, the material must be treated with an antiseptic composition. The presence of cracks is also dangerous: if they are identified, then before profiling they must be covered with special mastics.

In addition, it is very important what degree of filing of the sides in the proposed source material:

• in the so-called two-edged beam, only two opposite faces are processed;
• three-edged has three processed surfaces;
• four-edged is distinguished by all pre-sawn edges.

With independent profiling, the most time-consuming will be the processing of a two-edged beam, while the following two varieties have no practical difference in profiling time. Moreover, sometimes for the external attractiveness of the house, and in the absence of the need for subsequent external finishing, they stop on a three-edged, cheaper timber.

Profiling a beam with your own hands is much more convenient as needed in the finished material, as can be seen from the video. Some dimensional distortions can be quickly corrected when profiling the beam of the next row. This eliminates any problems with inconsistencies.

The standard length of an unprofiled beam is 12 m, in which case the amount of waste will be minimal. When calculating the dimensions of the cut groove, it must be remembered that its height and width should not exceed 30-35% of the corresponding cross-sectional dimensions of the source material. Only timber with normal moisture content should be profiled - not higher than 8%, otherwise the wood processing itself becomes more complicated, and the dimensions of the finished product may not meet the requirements.

How to make a profiled beam with your own hands

Every year the assortment of lumber only increases, and the types of products for the construction of a wooden house or cottage are getting closer to the ideal. But what to do with simple non-profiled timber, which is gradually being replaced by its counterparts - glued and profiled timber. After all, using an inexpensive version of edged timber is much cheaper. Craftsmen solve this problem in their own way.

How to make a profiled beam with your own hands, saving money?

There are several options for manufacturing a profiled beam from a regular one, which allows you to save money and get better material for construction. All that is needed for this is a little patience and free time, as well as the ability to handle some tools.

Many people ask themselves questions: “Does it make sense to make a profiled timber with your own hands?”, “Maybe it’s easier to buy a ready-made one?”. Of course, buying ready-made material is much easier. However, there are many reasons why the manufacture of profiled timber is especially important:

1. The profile must be of such a geometric shape that it is not blown through. And you do it only for yourself, which means that the profile will be made with high quality.
2. By making profiled timber yourself, you will save 3-5 thousand rubles from each cube of material. Of course, much more time will be spent.
3. Walls made of this material do not need additional finishing, since the insulation will be invisible.
4. The crowns can be made more precisely, and the connecting ones will fit as tightly as possible to each other.

What is the best profile to do?

When choosing a profile, it is better to calculate your skills and strengths. Making a profile on a bar on your own - it just seems like a simple matter. It takes a lot of perseverance and time to carry out such a task more efficiently. When choosing a profile, it is worth stopping at the simplest designs. To implement them, you do not have to use many types of tools and do not have to do a lot of calculations.

Carefully read GOST 9330-76 "Basic connections of parts made of wood and wood-based materials", it will allow you to calculate everything correctly. As a rule, two types of profile are made: profiling through a triangle or profiling through a rectangle.

It is important to understand that before you make a profile, you need to calculate its height, depth and width. Moreover, for each section of the beam, it has its own and helps GOST. Be that as it may, when building a house from this timber, a heater is laid between it (at least 5 cm thick).

How to make a profiled beam with your own hands: ways

Perhaps this is the easiest way. The milling cutter must be powerful, at least from 1.5 kilowatts and have a special nozzle. In the event that the profile is simple, then the radius of the cutter used will be 4-5 cm. If it is complex, then several types of cutters are produced. If desired, this tool can even make a D-shaped side of the beam. But here you still need an electric planer and a grinder.

It all depends on what kind of manufacturing accuracy you plan to get as a result. The very concept of "profiling" implies the purity and accuracy of the surface. The advantages of this option: if you use a sharp milling nozzle, then it is quite possible to do without subsequent grinding.

But this option also has disadvantages:

• a milling machine is quite expensive (5-10 thousand rubles);
• it is not always possible to buy the right nozzle, it may not exist for the milling machine that you have available.

Good for cutting straight grooves.

1. Use of a circular saw.

A good way to make a connection on your own is to use improvised tools. For example, using a hand-held circular saw. Such a tool will cost you 3-5 thousand rubles (the price depends on the manufacturer). The main thing is that it can be sawn at the required angle and make a cut of 65 mm.

The advantages of this method:

• the ability to control the accuracy of cutting in depth;
• easy execution of a smooth and straight groove;

Flaws:

• cleaning the groove with this tool will not work;
• there may be insufficient depth of cut;
• each time you need to reconfigure the depth of cut;
• low speed at work.

It is best to resort to it for cutting a triangular groove.

In both versions, this is a painstaking and long work that requires preliminary measurements and accuracy.

Of course, you can successfully combine these tools with each other. For example, if you need to make a quarter with rounding, first cut with a saw, and then round with a router. Do not rush to throw away sawing waste, as they will be useful for joining the timber.

1. Corner connection of a bar.

It can also be made by hand. It is usually made in two types:

• connection in a warm corner;
• two-way or one-way simple connection.

All connections are made in accordance with GOST 30974 - 2002. As for the choice of cutting bowls, here you need to build on your own knowledge and skills.

Tools you will need: a milling machine or a chainsaw with a special tool, marking templates, a pencil, an ax, a tape measure and a puncher. A puncher is used to drill holes for dowels.

Two way or one way connection

With a two-sided connection, the bowl is cut out from two sides, with a one-sided connection, the bowl is cut out from one side.

At the end of the beam, it is necessary to measure a distance in width equal to the width of the beam, and in depth - half the section. Making such a connection will not be difficult. Next, the bars are stacked on top of each other. Such a connection is often called "cold". This design requires an insulation pad of at least 5 cm.

Connection in a "warm corner"

It should be said right away that it is not easy to do it. This requires precision and special skills. But a warm corner is able to keep heat better and allows you to make the corners smoother.

There are several types of connections in a “warm corner” that you can do yourself: a connection with a root tenon, a key connection.

Make templates according to which the beam will be marked. For example, you can make it from wooden slats. Next, you need to attach a template and perform 3 saws with a chainsaw to the required depth. Then the surplus is chipped off with an ax along the notch. Protect the finished groove. It is important that the cuts have a large size, namely, they are half the cross section of the source material. Thus, it compensates for them during the shrinkage of the house.

Tow tightly fit between the joints. It will be much more difficult to caulk a "warm corner" after laying. Connect the crowns using metal or wooden dowels. Wooden dowels are made from the remains. When drying the timber, the iron dowels will be visible, which will spoil the aesthetic appearance.

Wooden pins are made with a diameter of 20-30 mm, sharpening them on one side. If you make them earlier, they will dry out by the time of construction. You can also make square pins, which will be even easier to make. Moreover, its diagonal should be 4-6 mm larger than the diameter of the drill used. The length of the dowel should be equal to 1.5 times the thickness of the beam. When drilling holes, this dimension must be taken into account, but adding another 2 cm.

They should not be drilled near the corner joints, as chips may form when the dowels are driven in. Such holes must be located in increments of 1.5 m and at a distance of 250 mm from the end.

It will be difficult to make such a warm corner yourself, especially the first time. It requires skills and ability to work with timber. However, if you have time left, you can practice on a thick board or old material.

As you can see, it is possible to make a profiled beam with your own hands, but it is quite long and painstaking. If you have the patience and time, doing this work yourself can save you money. However, if you do not have sufficient skills, we recommend that you spare your strength and nerves by buying a ready-made timber with chopped bowls.

Do-it-yourself beam profiling features

• Some Features
• Advantages of self-made profiled timber
• What type of profile is best?
• Making a profiled beam with your own hands
• What is the purpose of using a circular saw
• A little about the competitor - glued beams

Every year, the lumber market expands its range. A variety of products intended for the construction of a wooden house are becoming more advanced. What to do with an ordinary bar that has not undergone profiling? After all, it is rapidly being replaced by analogues - profiled timber, the latest glued timber, etc.

Scheme of connecting profiled timber.

The use of edged timber is much cheaper. Today it has become quite possible to profile the timber with your own hands.

Some Features

Material for construction, which is made from coniferous wood, having a certain size, is called profiled timber. In most cases, it is made from pine, spruce or cedar. If you carefully examine the material, it will immediately become clear that the inner side of the beam is made very even and planed, and its outer side is made semi-oval. Sometimes it can have an even shape.

The profiled timber has a specially made groove and spike on the sides.

Methods for connecting lamellas.

This is necessary for fast and high-quality fastening of the bars with each other. The main advantage of profiled timber is environmental friendliness, as it is made without the use of glue.

In addition, profiled timber is a warm and inexpensive material. Such positive qualities attract a large number of buyers. After all, profiled timber is assembled very quickly and easily, and this is in the hands of those who are engaged in independent construction.

However, you must always remember that profiled timber is wood, and pores may remain on it. Over time, it can become moldy, fungi appear, and so on. In this regard, the wood must be treated with special protective materials.

Profiled timber never cracks. Their appearance indicates the quality of the wood. Over time, these cracks may begin to widen. At this time, care must be taken not to form a through crack.

Profiling a beam with your own hands is quite possible to carry out in several different ways. Thus, it is possible to save money and produce high-quality material for construction. Many will say that this is absolutely impossible to do.

However, we can safely say that independent profiling of a beam is quite possible, you just need to have a lot of time, be patient, and, of course, experience in handling such a tool.

Modern trends in construction make it possible to obtain more environmentally friendly and durable material every year, which cannot but include profiled timber. This product has a number of advantages:

1. High strength;
2. Excellent noise and heat insulation;
3. Ideal geometric shape;
4. Availability;
5. High productivity and fast payback;
6. The ability to eliminate defects on uneven timber;
7. Ease of installation.

Due to its advantages, profiled timber has found wide application in the construction of cottages, villas, summer cottages. In order to get a profiled beam, you need a special machine. Of course, you can buy a ready-made timber, but it is much more expensive than buying a forest to perform profiling on your own. However, what to do if it is not possible to buy an expensive machine for the production of profiled timber, the cost of which is 150-400 thousand rubles. The answer is quite simple - you can assemble a cutter for profiling a bar yourself, and now we will look at how to do it.

Do-it-yourself beam profiling machine - step by step process

Profiled timber requires high-quality assembly equipment. To know what the machine should consist of, let's look at what functions it should perform:

1. Multi-saw processing of timber;
2. Four-sided processing of timber: planing and profiling;
3. Trimming and marking of profiled timber;
4. Mezhventsovoe connection - a cup is cut out.

Previously, 4 separate machines were used for such processing, which significantly complicated and increased the cost of manufacturing technology for profiled timber. Today, however, one device can handle this.

The profiling machine consists of:

1. Bed;
2. knife drum;
3. Engine;
4. Movable frame with the ability to adjust the height of processing;
5. Fasteners and stoppers.

Step-by-step process of manufacturing a machine for profiling 150x150:

1. The first step is to choose an engine. Under our parameters of the finished timber 150X150, we can recommend a Honda brand gasoline power unit with a volume of 196 cm3. 6.5 HP - 3600 rpm.

1. then, with the help of metal plates, channels and corners, we make a frame structure for mounting the engine on top of the machine, which, with the help of pulleys, will rotate the knife drum. To do this, you can use ready-made machines and take measurements from them.
2. the profiled machine will move along the guides with the help of rollers that will be attached to the corners of each side. There should be 4 rollers in total, which we fix at the bottom of the frame structure;
3. after that, we proceed to fixing parallel to the knife drum motor, which will interact with the help of pulleys. It is worth considering that in order to regulate the height and depth of timber processing (5-10 cm), the knife drum, together with the engine, must move along the vertical axis. To do this, you can use the adjustable stops, which can be fixed.

1. then we need to make a frame (emphasis), on which the beam will be located and the profiling machine will walk:

a) it is necessary to measure the length of the beam, which will need to be processed, for example, take 6 meters;

b) now we turn to the manufacture of the bed, where the timber will be fixed. It is necessary to make two metal guides 7 meters long. Our processing engine will drive on them. The width of the guides must be selected from the account of the rollers, which you can find under the mobile machine;

6. when the guides are made, they must be fixed with the help of channels between each other. To do this, you can use an I-beam or conventional channel;

7. we set two guides to the width of the machine and begin to fix them with channels in increments of 50-80 cm, depending on the thickness of the guides and the channels themselves;

8. when all the channels are welded, we proceed to welding special square or rectangular plates on them at the same height. Our processed timber will lie on these plates. We place the plates strictly in the center of the channel, so that the knife drum during operation is located in the middle of the plates. Every 1-1.5 meters from the bottom to the channel we fix special adjustable clamps, you can use clamps that will securely hold the processed timber.

9. After the bed is fixed, you can install a frame structure with a knife drum and a motor on it. To process the timber, you can use curly, straight, semicircular knives for making grooves. To prevent the machine from moving beyond the guide frame, special stops can be welded along the edges.

Advantages of self-made profiled timber

It is much easier to purchase a ready-made profiling beam and then start construction. However, the independent production of profiled timber remains relevant today.

1. Independent production of profiled timber will provide an opportunity to save tens of thousands of rubles. True, it will take much more time.
2. You can make a profile of any geometric shape. As a result, any blowing can be avoided. Remember that you are making a profile for yourself, so the quality will be on top.
3. Walls made of this material do not require additional finishing. In this case, the insulation will be hidden from the eyes.
4. The crowns will be made with a higher quality connection, will always be the tightest, without gaps.

What type of profile is best?

When selecting a profile, you must definitely think about your manufacturing experience. Independent production of a beam profile seems to be quite an easy task. However, to obtain a high-quality timber, experience, time and perseverance will be required.

It is best to choose the profile of the simplest designs. In this case, you do not need to use a special tool, you do not need to do a lot of calculations.

On the basis of the developed standards concerning the main connections of wooden parts, profiled beams are made. This document shows the calculation algorithm. It is possible to manufacture a profile of two types:

• profiling through the bar;
• another profiling done through a triangle.

Before starting the production of a profile, you must first calculate its dimensions. Each section requires a specific calculation. The algorithm is given in the current GOST. When building a house from this beam, a heater must be laid, the thickness of which must exceed 5 cm.

Making a profiled beam with your own hands

You can perform independent profiling of a beam in a variety of ways. The easiest will be to work with a milling cutter, a tool for manual work. Its power should reach one and a half kilowatts. The work is carried out using special nozzles.

When there is a simple profile, a cutter with a diameter of 10 cm is used. When the profile has a complex shape, several different cutters are used. This tool makes it possible to independently produce the D-shaped side of an existing profiled beam. But for such an operation you will need a grinder and a special electric planer.

In this matter, the most important thing is the accuracy that you need. After all, the term "profiling" means perfect cleanliness and exact dimensions.

The advantages of this method:

• when the workpiece was made with high quality, then the most accurate result will certainly be obtained; however, during operation, it is imperative to accurately guide the milling cutter;
• if the milling head is perfectly sharpened, then no further grinding is required.

However, this method also has its downsides:

• the milling machine is expensive;
• it is difficult to buy the right nozzle: sometimes it is simply not produced by manufacturers for the machine you are using.

What is the purpose of using a circular saw

Another way to profile the timber is to use improvised tools. For example, using a circular. The cost of such a tool is about 5,000 rubles, the main role is played by the manufacturer's brand. It is very important that such a saw can create cuts at different depths.

The advantage of this method:

• it is possible to control the accuracy of the cut size;
• straight and perfectly smooth grooves are obtained quite easily.

Negative properties of a circular saw:

• sometimes the depth of cut is small;
• it is impossible to clean the groove with such a tool;
• for each new operation, a reconfiguration of the tool is required;
• work is done at low speeds.

The circular is best used to obtain a triangular groove.

Of course, these tools can work together. For example, to get a rounded quarter, you must first use a saw, all rounding will be done by a milling cutter. It is better to save the resulting waste after sawing. They will be needed to connect the bars to each other.

Profiled timber is much more expensive than non-profiled timber. Can you save money by doing the missing steps yourself?

What are the advantages of do-it-yourself timber profiling:

1. Financial savings, and quite significant.
2. The profile can be made for specific needs (in particular, either reduce or make it impossible to blow through the house).
3. There is no need for facade decoration.

How to choose the final profile and the necessary equipment

First of all, we note that profiling a beam with your own hands will require a significant amount of time from the performer. Therefore, it is worth choosing the least labor-intensive profile in manufacturing, “adjusting” the frame of the future house for it. It is recommended to make profiling either “into a bar” or “triangle”, as in the photo.

To perform any of the options, you need special equipment. In particular, you will need a mobile woodworking milling machine with an appropriate set of cutters and a power of at least 1.5-2 kW. To improve the accuracy of an already completed profile, you can not do without a grinder. The disadvantage of this option is the high cost of equipment, which will most likely have to be rented. But it is possible to profile a beam with almost any of its cross sections.

If it is necessary to make a straight groove along the entire length, a circular saw is often used, which is cheaper and more common in the household. Profiling a straight groove with a circular saw is somewhat easier, since the depth of the groove (more often a “triangular” groove) can always be controlled. True, the time for profiling the beam will increase slightly, and it will be impossible to clean the finished groove. In addition, the characteristics of the saw itself should be clarified - it should allow the possibility of cutting a groove with a depth of 65 mm or more.

Ideally, the home master should have both a milling cutter and a circular saw.

Profiling Technology

When purchasing an unprofiled timber, you need to ask if the semi-finished product has undergone preliminary antifungal impregnation. If not, then after the final readiness, the material must be treated with an antiseptic composition. The presence of cracks is also dangerous: if they are identified, then before profiling they must be covered with special mastics.

In addition, it is very important what degree of filing of the sides in the proposed source material:

• in the so-called two-edged beam, only two opposite faces are processed;
• three-edged has three processed surfaces;
• four-edged is distinguished by all pre-sawn edges.

With independent profiling, the most time-consuming will be the processing of a two-edged beam, while the following two varieties have no practical difference in profiling time. Moreover, sometimes for the external attractiveness of the house, and in the absence of the need for subsequent external finishing, they stop on a three-edged, cheaper timber.

Profiling a beam with your own hands is much more convenient as needed in the finished material, as can be seen from the video. Some dimensional distortions can be quickly corrected when profiling the beam of the next row. This eliminates any problems with inconsistencies.

The standard length of an unprofiled beam is 12 m, in which case the amount of waste will be minimal.

When calculating the dimensions of the cut groove, it must be remembered that its height and width should not exceed 30-35% of the corresponding cross-sectional dimensions of the source material. Only timber with normal moisture content should be profiled - not higher than 8%, otherwise the wood processing itself becomes more complicated, and the dimensions of the finished product may not meet the requirements.
