Nowadays, wooden houses, for the construction of which rounded logs are used, are very popular, because this material is environmentally friendly and safe. The buildings create a comfortable internal microclimate at any time of the day, providing natural heat exchange and constant air ventilation. A house made of rounded logs has different pros and cons, just like buildings made of other building materials, so each person decides for himself whether this option is suitable for him or not.

What are rounded logs
A rounded log is a building material that is a milled log that has undergone mechanical processing using a special technology. All logs have the same diameter along their entire length. It should be noted that they can be given the desired profile depending on the processing machine used.

When producing logs, before rounding, everything is necessarily sorted by diameter and then sent for processing. Then the material is coated with a special water-based antiseptic. The product contains substances that prevent destruction from high humidity. In addition, the antiseptic tightly clogs the capillaries of the wood, so it dries naturally and is not affected by blue stains and fungus.

Wood type
Pine is most widely used in construction due to its optimal price-quality ratio. The distinctive features of pine rounding are its beautiful structure, strength, relatively low thermal conductivity, resistance to external influences and affordable price. Arkhangelsk pine stands out because it practically does not crack.
Spruce can be considered an analogue of pine. It has fewer knots and is easier to process.
As for cedar, its spread is hampered by its high price.
The same judgment is true for larch. Which is the most suitable raw material for the production of rounded logs. Larch is resistant to temperature changes and moisture, has high density and strength. However, the cost of a rounded larch log is twice the price of a similar pine log. Such characteristics of larch logs have led to the fact that it is used as the main one when forming the lower crown of a log house.
Why do people choose houses made of rounded logs?
A log house, the pros and cons of which are determined by the characteristics of the building material used, is in quite high demand. This popularity is due to the fact that these buildings compare favorably with those constructed from other materials:
- Attractive cost. The final price of houses depends, of course, on the model of the building constructed, its decoration and other features. Indeed, in this case you can save a lot on finishing work, sound insulation, heating, hoods and many other aspects.
Preparation of necessary documents
If you plan to cooperate with government agencies, large woodworking companies or foreign companies, then it is better to issue LLC documents. In addition, a legal entity is the only option if several founders are involved in the business or you are afraid that the company will go bankrupt (the founders of an LLC do not risk their personal property in such situations).
Entrepreneurs who plan to sell products to individuals or small firms can save on registration by completing individual entrepreneur documents. But, regardless of the organizational and legal form of your business, you must choose OKVED codes that correspond to your activity. In this case, the following are suitable:
- OKVED 20.30
(production of wooden carpentry and building structures). - OKVED 20.10.1
(production of lumber whose thickness is more than 6 mm).
In addition, you need to fill out paperwork with Rospotrebnadzor and the fire inspectorate, and also receive a quality certificate confirming that your product meets established standards. No more permits or licenses are required.

Installation
For work, an old sawmill is used, on which the body is replaced with a stop and tailstocks for clamping an unbarked trunk. A tapered or other roller bearing is installed as a holder. In order for the log to easily rotate along its own axis, you will need an additional motor; manually the process will take a long time.
To move the cutter, the simplest solution is to lay a rail track. There is no need to drag heavy whips by hand. The distance between the transverse sleepers, which reinforce the structure and on which the rail is attached, is no more than 1 m; for installation, timber impregnated with special compounds or ready-made sleepers are used.
Installation of a homemade machine for rounding begins with assembling the frame. Using a welding machine, its sections are prepared separately. And during assembly, they check with a level so that the structure is in the same plane. An error of 0.5 mm per meter is allowed, since perfect evenness will still not be achieved, and a heavy log will smooth out the discrepancy in the future.
The milling unit is strengthened and assembled from lathe parts. After all, in addition to rounding, you need to cut out a cup on the barrel. This requires a special vertical cutter, which is made independently or ordered from the manufacturer’s catalog.
Now connect the motor for rotation. Immediately provide a power supply with the recommended voltage in the room intended to be a home sawmill; the power cable must go separately and be connected to an independent panel, otherwise constant knocking out of household appliances in the house cannot be avoided, which cannot affect their operation. The engine is strengthened with anchor bolts. The correct connection is indicated on the case; the movement of the power head must coincide with it. If there is a discrepancy, swap the phases.

Connection cables for various components are installed over the entire length of the finished machine with a margin. Safety of use lies in strengthening them above the machine with flexible holders. Do not let the cable sag, much less touch the work surface - cutting it is fraught with consequences.
Before putting into operation, the machine for rounded logs is checked for parallelism of the axes of the headstocks, front and rear. The moving cutter must run exactly horizontally. If this is not done, the least trouble that occurs during operation is the curvature of the barrel. Large – failure of the entire system. In addition, the error of parallel lines leads to the play of the log, especially with poor fixation.
Features of the technology of building houses from rounded logs
First of all, with the help of specialized woodworking equipment, pre-processing is carried out, during which the logs are given a round cross-section. Next, you need to adjust the building material to size, and then treat it with an antiseptic and label it.

Today, when preparing the so-called “house kit”, most manufacturers use the “moon groove” technology, which makes it possible to create the maximum tightness of the timber during the construction of the building.
Stages of construction of houses made of rounded logs
In order to minimize the disadvantages of a house made of rounded logs, it is necessary to strictly follow the construction technology recommended by experienced specialists, and also take into account all the nuances associated with working with such building materials.

Advantages and disadvantages of houses made of rounded logs
Today, various modern technologies are used that make it possible to build housing of different sizes, parameters, as well as any level of complexity. When choosing a rounded log for building a house, the pros and cons must be taken into account, regardless of the specifics of the project.

pros
Such buildings are extremely popular due to the fact that they have a fairly large number of different advantages:
- Housing made from this building material is characterized by naturalness and environmental friendliness. Experts say that the wood used contains an increased concentration of resins and phytoncides, which have a positive effect on human well-being.
- Walls made of logs have a natural and fairly soft shade, which helps create a calm and harmonious environment, as well as a good mood.
- The aesthetic appeal of the object will not leave anyone indifferent - this is one of the main aspects of the popularity of rounded logs. After all, the result is a building that maximally conveys the natural beauty and natural grain of wood.
- Another important advantage is the energy efficiency of such houses. These options are especially suitable for settlements in the middle zone, where weather conditions force the construction of houses with very good thermal insulation. It should be noted that the thermal insulation properties of wood are approximately five times higher than those of concrete or brick. Therefore, buildings made from it constantly retain heat during the cold season, and there are no drafts in the summer.
- Due to its fibrous structure, characteristic only of such material, wooden logs have the ability to “breathe”. Due to this, water vapor constantly escapes from the premises, which helps create a comfortable microclimate in the rooms.
- If logs that have been carefully processed are used to build a house, and all technology standards are followed, then it will last for quite a long time.
- Many people are concerned about the fire safety of these objects, and also about the fact that wood is a material that is often subject to destruction by fungus and blue stains. But this should not be a cause for concern, because the latest methods of processing logs significantly improve the quality and increase the durability of the tree. In addition, fire resistance is ensured through the use of fire retardants.
- Increased wall strength.
- To build a house, fairly simple technologies are used, and the process itself takes relatively little time. Using special computer techniques, you can quickly perform all calculations and check them so that all the grooves in the logs correspond to the required values.
- High quality and reliable connection of parts.
- Using round-shaped logs for construction, the owner of the site can turn almost any of his ideas into reality. For example, he has the ability to construct a building with configurations of varying complexity. This is due to the fact that the materials used are easily connected at the desired angle, which does not affect the quality of heat conservation in the premises.
- Interior finishing requires a relatively small amount of money.
- There is no need for a very powerful foundation, which also allows for great savings.

Minuses
However, residential buildings built from rounded logs also have a number of significant disadvantages:
- It is very difficult to find a supplier offering high-quality products, so there is a risk of purchasing building materials that will be processed using the wrong technology and impregnated with low-quality antiseptics and fire retardants.
- This option is best suited for creating houses in the classic Russian style, and not in the European one.

What financial investments do you need to make to open your own log rounding shop?
To open an enterprise with a capacity of 250-300 cubic meters. an amount of 80-120 thousand dollars per month is required. It includes: costs for registration and execution of all documents, rental of premises, purchase of equipment, office equipment and furniture, as well as the purchase of additional tools, carrying out repair work and installing a production line. In addition, do not forget that the enterprise will not immediately begin to make a profit. It will take at least 2-3 months until it reaches the level of self-sufficiency, and until that moment you will finance monthly expenses from your own sources.
