If a person is often faced with the fact that he needs to make something out of wood, just likes to do it or makes things to order, then he just needs a machine. Acquiring such things is not only expensive, but they also do not always fit in size, may be uncomfortable or do not fit into the design. But a home-made do-it-yourself machine, made to the right size, will fit perfectly into the space of the room and will always be comfortable.
Engine
If it was decided to manufacture this device on our own, then it is important to choose the right components. For example, in order to design a wood milling machine, you will definitely need an electric motor. This part can be of several types.
The first type of motor that can be used in the manufacture of a do-it-yourself machine is an asynchronous one. The advantage is that it does not require maintenance and will also allow you to work with a larger cutter. Among the shortcomings, a large amount of noise can be distinguished, whichemits the engine during operation. However, this is a purely individual question.
Collector motor. This option is somewhat worse than the previous one, for the reason that over time and the work of the part, the brushes that have to be changed are worn out. The more and more intensively the engine is used, the more often the brushes will have to be changed.
Engine power
Choosing the type of engine for a homemade machine with your own hands is not all. You need to pay attention to the power of this element. This is a very important indicator.
Machines up to 0.5kW are best suited for surface finishing of material. It is worth adding that only the softest wood species can be processed on such a machine and only small cutting tools can be used.
The second type of engine power for a do-it-yourself machine is 1.2 kW. As practice shows, this indicator is the most universal and in demand. This power is quite enough for deep processing of wood. For home use, 1.2 kW is enough.
The last type of power is up to 2 kW. Most often, such machines are already semi-professional. They open up wide possibilities for wood processing, allow you to use almost any type of cutter, as well as process some types of plastic and soft metal - aluminum.
The number of revolutions and power of the workbench
If we talk about the number of revolutions for a do-it-yourself machine, then everything is quite simple and clear. Howthe higher the numerical value of this characteristic, the cleaner and more efficient the final processing of the wood part will be. However, there is another small plus. If the number of revolutions is high enough, then such wood defects as knots are not afraid of such an engine. The cutter will pass them without any problems.
Food is pretty simple too. Most often, those engines that are powered by 220/50 are selected. Installation and connection of this type of motor does not cause problems. A little more difficulty arises when connecting elements with a three-phase supply.
Workbench and machine frame
A self-made woodworking machine must have such an element as a workbench. The choice of its dimensions should be based on what parts you will have to work with in the future. The dimensions of the table on which all this will be mounted do not really matter.
The frame for the machine must be selected so that it is not only very strong, but also able to withstand dynamic loads. The main difference between an electric woodworking machine assembled by oneself and a manual one is that the device itself will not move, but the workpiece will have to be actively moved. From a practical point of view, using wood for a machine frame is not a good idea. All due to the fact that over time the tree dries out, becomes covered with cracks and loses its strength. The best option would be a metal pipe that has a square or rectangular profile.
Table top
When choosing this element, everything is exactly the same as with the frame, but vice versa. Metal would not be the best choice as a starting material for two reasons. Firstly, the countertop will turn out to be very massive and will look too rough. Secondly, you will have to use welding to secure everything.
It is best to use one of the following three materials:
- planed boards;
- chipboard, OSV;
- plywood.
The material for the countertop must be strong enough to withstand subsequent loads. For this reason, the thickness and material for the manufacture of this element must be chosen based on what work will be carried out in the future. Another important detail is the smooth surface of the table. If you do not follow this recommendation, then you will not be able to make an accurate cutter. If it is important to assemble a home-made machine with your own hands so that it can be used to produce workpieces of decent quality, then this is one of the most important conditions.
In order to ensure a perfectly flat surface, you can use methods such as: lamination, upholstery with sheet iron or precise fitting of planed boards.
How to make a machine with your own hands
The order of assembly of this device begins with the fact that it is necessary to determine the location of the engine. The best option is to install this element under the table. On the motor shaft, which must be directedvertically up, position the cutter. In order to facilitate the assembly procedure, it is best to make a drawing of the machine with your own hands, on which all the details were shown in advance.
