To cut small parts or crafts from wood, you need a jigsaw machine. He easily copes with different thicknesses of wooden blanks and easily cuts wood with a treated surface.
As a rule, a jigsaw machine does its job well, while the hands can be free from control of the workpiece and you can cut a variety of bends and curves. Therefore, when working, it is safe, which is important.
A tree 5 cm thick can also be sawn with a small machine, and in order to saw the wood thicker, you need a jigsaw machine with more power. The jigsaw desktop can be made of various materials, for example, extruded metal. The main thing is that the surface of the table is smooth, flat and rigid. To cut oblique cuts, you need to tilt the table, so in many models the jigsaw tables are tilted. And in some models they even rise and fall so that it is possible to use different parts of the saw blade, as it will wear out over time.
The machines are equipped with electric motors, even a 100-watt engine develops a jigsaw blade speed of up to 1,600 strokes per minute. Some models have the ability to adjust the speed. Despite the fact that the jigsaw machine can saw different thicknesses of the workpiece, the stroke of the saw blade remains short. And if you constantly saw only thin workpieces, then that part of the file that is located above the table will become dull. Therefore, in order to rationally use the saw blade, you need to periodically put on the table, for example, plywood of small thickness.
The jigsaw file must be tensioned so that it does not bend during work during loading, since its blade is very thin. Some models have a mechanism for adjusting the tension of different sizes. On jigsaw machines there is a fence, it is necessary in order to prevent contact of the fingers with the file. Usually this is a simple transparent plastic screen, but if the workpiece feeds correctly, then a guard may not be necessary. In addition, when working, you must have a clamping device with you - it is required to prevent vibrations, since the workpiece can be lifted from the movement of the canvas. In good and high-quality machines, a tube is provided for cleaning sawdust from the back of the blade. Air flows through this tube under pressure, which blows off all the debris along the marking line.
A home-made jigsaw machine can be used for some homework, for example, for the manufacture of home-made furniture, decorations of various buildings and interiors, sawing patterns from wood, etc. In order to make the machine at home, you can use different materials: wood, metal, caprolon, etc. A bed with a motor and a rocking chair with a file are the main components of the machine. The motor of the sewing machine can also serve as an electric drive. To make a jigsaw machine with your own hands, you need to take into account all the components of the machine, perform assembly and fastening, check the safety of its operation.
