Most suburban residents are familiar with the need to use a variety of woodworking equipment, which is often used for household purposes in the backyard. The modern market of manual and stationary construction tools abounds in various models of devices for woodworking, to the most popular of which are the sawmill. Thus such equipment is subdivided into the device of the bus, disk, frame and tape type depending on the used method of sawing wood.
What is a tire sawmill used for??
Man has long used wood of various breeds to make structures and objects, used in everyday life. At the same time, people were constantly trying to improve their woodworking equipment with their own hands. Hand saw, which was recently considered the only mechanism for sawing wood at home, slow, but confidently surrenders his position, giving way to machines, running on electricity or liquid fuel, which greatly facilitate human labor.
No construction is without significant financial costs, related to wood processing: sawing boards, construction of rafter structures or manufacture of furniture. Naturally, all these items can be purchased at any store, but this is not always financially justified. Man, who used to do everything with his own hands will be able to assemble a tire sawmill - a machine, thanks to which it is possible to make any arbor, wooden barn or garage box, bath or log house and many other wooden structures.
The main purpose of the sawmill tire design of their own hands is high-quality sawing of logs in the longitudinal direction for the manufacture of unedged and edged boards, rail, carriages and other lumber, used in construction. Homemade tire sawmills were developed for the production of small batches of wooden construction blanks of non-standard sizes and processing of various types of wood.
It does not take much space to install the tire spraying equipment, which allows you to use it on a small plot of land. Naturally, such a sawmill will not be able to fully replace a cylindrical machine or cutter, but it is quite suitable for self-cutting of a bar and production of boards. Today there is stationary equipment, powered by electricity and power saws, which can be moved through the use of a gasoline engine, which is very convenient when harvesting lumber in the woods.
Designs and types of tire sawmills
To date, you can consider two types of tire sawmills, which you can actually make with your own hands:
- with the movement of the working unit relative to the processed wood;
- with longitudinal method of feeding wooden blanks.
Thus to allocate any model, which will be better, can not, since both types of spraying equipment have advantages, and shortcomings. So, when moving the working unit along the log, the person has the opportunity, control the efforts made, thereby ensuring uniform running and sawing of wood at high speeds.
When feeding the log in the direction of the sawing mechanism significantly complicates the control of sawing. It is enough to push the tree a little harder and this will immediately lead to a sharp increase in the load on the tire and chain. This can cause the chain to jam or the motor to overheat. But in such a mechanism there are no additional wires, moving behind the main unit. Naturally, the final choice of a design of power-saw benches for manufacturing by own hands depends on individual preferences of each person.
But regardless of the chosen design, you need to take care of building a quality foundation, which will reduce vibration. Most often for the basis of self-made sawmills of bus type use metal channels or rails. The lower part of the frame is equipped with wheels to ensure free movement of sawmills or machined wood..
Making sawmills with your own hands
Before proceeding to the assembly process, you need to take care of the availability of materials and tools from the following list:
- schematic drawing of a power saw;
- channel or rails of metal;
- branch pipes of various section;
- electric motor;
- tire and sprocket from the chainsaw;
- welding unit and electrodes;
- electric bulldozer and drill;
- hammer, roulette and chalk.
Spare parts from a standard chainsaw are used to make a tire sawmill with your own hands. The working part consists of a tire, electric motor and clutch system, which are contained in a separate case.
Stages of assembly of the spray mechanism
Having assembled independently a sawmill of tire type the person, will receive an indispensable assistant to solve household problems. At the same time, there is a certain sequence of measures for its independent compilation.
- The first thing to do is make a rectangular frame. The tire is placed in the center of the base. Considering, that this element will be held, high load it is securely fastened on both sides.
- In most cases, the slave sprocket already has a hole, is intended for fastening of an element on a steel axis from a high-strength alloy. The axle avoids the movement of the tire in the horizontal direction. To prevent vertical displacement, two bearings are mounted as tightly as possible to the tire on the axle on both sides.
- The next step is to put on the sleeve, which clamps the bearings of the strip where the axis is welded to one side of the frame. On the opposite side is the electric motor and the chain tension control system. You do not need to invent anything, and you can just use ready-made spare parts for chainsaws.
- The drive drum is mounted on the shaft of the electric motor and fixed with a longitudinal key.
- At the finishing stage, the structure is centered and securely fixed in the housing.
Careful attention should be paid to mounting the engine when working with your hands, which will vibrate strongly during operation. So you need to take care, that the bed under it had sufficient rigidity.
Installation of a design on a basis
After assembling the working unit, it must be fixed on a metal frame, making which with their own hands consists of simple actions.
- Two blanks are welded from strong steel tubes, in shape reminiscent of the letter "P". The upper parts of the obtained blanks are fixed to each other by electric welding or bolts.
- In the center of a framework four branch pipes placed vertically are welded. On each element on the outside several small deepenings on distance are made 20 mm relative to each other to a depth of half the diameter of the tube.
- Four tubes are also welded on the working site, the inner cross section of which must correspond to the outer diameter of the pipes, placed on the base. Placement of elements, should be performed as follows, that branch pipes on a working site put on tubes of a bearing basis.
This design is necessary to ensure the free movement of the spray unit in a vertical position. Fixing of a working knot in necessary position on vertical is provided by means of bolts.
Stationary design of tire sawmill
Sometimes a homemade sawing device is placed on a concrete base. This allows you to ensure constant horizontality, but at the same time significantly slow down the process of sawing logs. To increase the convenience and efficiency of the tire sawmill, with your own hands you can additionally install an intermediate transmission mechanism - the clutch.
To do this, you need to mount a belt drive between the drive gear and the electric motor. Pulleys are mounted on the gears and the motor shaft, on which the belts will be stretched. Special rollers are used to press the belt product. To facilitate the work, you can borrow a ready-made design from the motoblock.
After getting acquainted with the design and principle of operation of the tire sawmill, everyone will be able to assemble such a woodworking machine with their own hands. This sawing device qualitatively dissolves logs on boards of any thickness with high enough accuracy. If a person is planning to harvest lumber or just has a lot of construction work related to wood, then self-manufacturing of the tire-type spray machine will save a lot of time, effort and money in processing, deck, boards and other wooden products.
