If you need to work with a large volume of wood or boards, it becomes necessary to create such a device as a homemade sawmill. Someone thinks that it is better to immediately buy a factory version, but if you want to make such a device with your own hands, it will not be difficult to do serious work even at home. The main thing is to understand how much work needs to be done, what kind of wood needs to be processed, and also choose the best sawmill option to complete this task.

How to make a band sawmill?

If we talk about a band sawmill, then it can be done only if there is welding equipment, because it is impossible to build it without connections of this type. To create it, you will need to have the following elements:

• welding machine;
• concrete mixer;
• pliers;
• bolts with nuts;
• electric drill;
• grinder;
• wrenches;
• drills for metal and concrete;
• building level;
• locksmith clamps.

In addition, you will need the following materials:

• shaped and steel pipes;
• a pair of long length screws with nuts;
• 50mm metal corner;
• rollers or ball bearings;
• gasoline or electric engine;
• wheels and hubs from a passenger car;
• chain transmission;
• cement;
• crushed stone;
• sand.

You will also need to have a drawing of the device.

In principle, in order to have the simplest diagram of such a device on hand, it is enough to draw a reduced copy of it and indicate the dimensions of each constituent element.

When creating a project, the length of the device should not be shorter than 600 centimeters, and the width - 300. Only with such dimensions, it is possible to create lumber of ordinary sizes.

After that, you need to calculate how much material will be needed to create the frame, as well as the guide rails . If the sawmill is operated in a building, then the resulting drawing will be enough - you can proceed to creating the base. It is thanks to him that the frame with the saw mechanism will be able to move normally. The slab where the guide rails will be installed should be made in the same way as a simple strip-type foundation - poured onto a 15-centimeter thick pillow made using gravel and sand.

You can add a reinforcing mesh of metal before pouring concrete. After that, the concrete should be infused for 2 weeks.

Now we turn to the sawmill, which will be made using wheels from a passenger car, an engine and a belt-type transmission . A corner or channel will be in the role of guides. The material should only be laid parallel to the inner edge, which is located upward, at a pre-calculated distance. After that, sleepers are mounted between the corners, which are made from a profile-type pipe. Now you can start welding the transverse reinforcements, which must never be overheated. After that, it remains to fix the metal structure on the concrete base using anchor bolts.

At the next stage, a bed should be placed in the middle area of the canvas to fix the wood. To hold the round wood, it will be necessary to weld a stand with protrusions on the sides in the shape of the letter H to the sleepers . Next, you need to make sawmill rollers from ball bearings. For each of the frame axles, you will need 2 with a larger diameter and 4-6 smaller ones. The difference will depend on the height of the corner rib. If the corner is 5 by 5 cm, then it should be 10 centimeters with equal internal dimensions of the constituent elements.

The creation of the frame starts with the installation of a pair of guides from a pipe made of steel . They are mounted vertically, and then sliders are placed there. The inner diameter should be at least different from the diameter of the outer type of direction pipes. Now we make a carriage frame from a profile-type pipe. It should have the appearance of a rectangular-type structure, on which it will then need to be installed by welding the guides in a vertical position, and from below - an axis equipped with bearings.

After that, a screw mechanism is mounted on 2 sides of the guide-type pipes, which will be responsible for the vertical transportation of the carriage . The nut should be welded to the slider and long studs are installed in the upper area of the frame.

It would be better to mount the stud on the bearings from 2 sides.

In order for the screw-type mechanism to rotate synchronously, it is required to weld small stars from a bicycle of the same diameter to each stud. And between them it is required to make a chain transmission using a chain from a bicycle. To ensure that the chain is permanently tensioned, a roller fitted with a spring on the lever must be used.

Instead of pulleys in such a sawmill, it is permissible to use wheels and hubs from a rear-wheel drive car . For easy rotation of the drive, it is necessary to assemble the bearing assembly, which will be welded from 2 sides to the carriage cross member. A pulley is mounted on one, where the torque from the electric or gas engine will then be transmitted.

To improve the safety of using the sawmill, in the lower area of the carriage, at each wheel, a saw support assembly should be made, consisting of an axle where a certain number of ball bearings are present. From the side of the hub, where the chic is set, we install the engine. If an internal combustion engine is installed, then in order to tighten the V-belt transmission, a spring-loaded roller is required.

If it is an electric motor, then the sawmill should be placed on a small base that can move horizontally . It remains only to install a container for washing and lubricating fluid, from where the tube is supplied to the cutting unit. Above it is mounted a casing made of metal corners and sheet metal. You can start using the received device.

Making a chain model

If we talk about a chain model, then the principle of assembling such a sawmill will be similar to the device mentioned above. The only difference is that here the main operating element will be a chain saw. The design of such a sawmill model will be simpler, and its dimensions will be smaller in comparison with the belt one. But it turns out that it will be easier to make it. The chain model should be installed on a level surface to ensure full access to it.

The assembly of such a model of a sawmill starts with the need to form a frame from a metal profile. After assembling the main part, there is a need to make several technological holes with maximum accuracy . The number will depend on the step length. After that, the assembly of the racks and the subsequent installation of the bed starts. Then you create additional stiffeners. That is, a chain-type structure frame is obtained.

You will also need to create a movable cart with your own hands . Here you should prepare the base and fix the stop, gaskets, as well as fasteners and clamping plates on it, because such a model will be with an electric motor. After that, the trolley is mounted to the frame, the motor is secured with the saw, and the chain is tensioned. This completes the creation of the chain model of the sawmill.

Other options

It should be said that there are other types of sawmills that you can create yourself. Among the most popular are the following:

• corner;
• from a chainsaw;
• tire;
• frame;
• sawmill logosol.

We will focus on the first two models.

Corner

If a person has a need to saw a large number of boards, then one of the solutions that can help to carry out his plan is a disk or corner sawmill. It is multifunctional and can be used to carry out a fairly large number of different jobs . It will be advantageous to do such a design on your own due to the fact that the price of a factory sample is extremely high. For its assembly, use the appropriate drawing documentation and ensure that the required tools and materials are available.

First, you need to assemble the frame from metal pipes, as well as assemble the guides, which will have good strength indicators . All joints are required to be fastened using a welding machine. It will be most correct to use rails as guides, after which it will be necessary to assemble the carriage.

Note that in the process of creation, it is required to pay a lot of attention to the accuracy of the values of the indicators that are displayed in the drawing documentation.

Quite powerful gasoline engines are usually installed in disk or angle sawmills . Sometimes there are models with an engine from a walk-behind tractor. Installation of the engine on a frame of this design and connection to the working parts is carried out using special holes. Most often, such devices are equipped with a chain-type transmission, but in some cases such a solution can cause the drive to overheat. In addition, when assembling such a model, one should not forget about safety precautions. Everything should be double-checked before starting such a homemade device.

From a chainsaw

In everyday life, it often happens that too large a sawmill is not needed. That is, a small machine is required. There are several varieties of mini sawmills that are medium in size and can be easily transported wherever needed . These can be called models from an electric saw or from a circular. But most often the device in question is created using a chainsaw, which will be the central element of such a design.

To assemble a sawmill from a chainsaw, you need to have the following elements on hand:

• rails;
• 2 channels;
• corners.

The assembly work will start with the creation of a frame, where several technical holes should be made. After that, the installation of screeds made of a metal pipe is carried out. Their fastening is carried out using bolts of fasteners in the holes that were made earlier.

During installation, control should be made to ensure that the corners between the parts are necessarily straight.

To strengthen the frame, several stiffening ribs should be installed . Now you need to make a movable cart from a plate made of steel. A pair of corners is attached by welding from below, after which it is placed on bearings or rollers. A couple of corners are welded on top, necessary for fasteners, where the chainsaw will be attached. At the final stage of work, a special structure should be installed, where the logs that need to be processed will be attached.

Useful Tips

A hand-made sawmill is an excellent tool that can really be useful to everyone. Considering that it is a highly hazardous unit, it will not be superfluous to analyze where it will be located before its creation. Here you will need:

• garage;
• barn;
• any utility room with a concrete foundation.

The place where the sawmill will be located should be ventilated and lit, there should be a lot of space. You can place it outdoors, but you will need to put up a canopy.

If the sawmill has an electric motor, then when creating it, a lot of attention must be paid to the installation of the wiring, as well as the required machines and switches. Besides, When assembling, attention should be paid to cutting and moving elements, which are a source of increased danger . Naturally, when using such a device, all safety standards should be observed.

Another important point is that after assembling the sawmill and before starting work, the components of the device, its fastenings, and how stable the structure is on the base should be checked.

The first start-up of the device can be done only after all the required recommendations have been fulfilled. These are the following points:

• monitoring the health of cables and their connections;
• checking the integrity of the grounding;
• switching off the device in case of a short circuit, or if it is required to replace the saw;
• it is worth being far from the nozzles from where the sawdust is emitted;
• excellent fastening of the log to the rails when working with the device.

As you can see, creating a sawmill with your own hands is a process that requires attention and certain knowledge. At the same time, each person, in principle, can make the simplest sawmill. The main thing is to have the required tools, materials and drawings of the device and clearly understand what exactly is being done and for what purpose.
