For sawing small parts or wood crafts, you need a jigsaw. It easily handles different thicknesses of wood and easily saws wood with a finished surface.
As a rule, a jigsaw does its job well, while the hands can be free from controlling the workpiece and you can cut out a variety of bends and roundings. Therefore, when working, it is safe, which is important.
A 5 cm thick tree can be sawn with a small machine, but in order to cut thicker wood, a jigsaw with more power is needed. The desktop of a jigsaw can be made from different materials, such as pressed metal. The main thing is that the surface of the table is even, flat and rigid. To cut bevel cuts, you need to tilt the table, so in many models the jigsaw tables tilt. And in some models, they even rise and fall so that you can use a different part of the saw blade, as it will wear out over time.
Machines are equipped with electric motors, even a 100 watt motor develops web speedjigsaw in operation up to 1600 strokes per minute. Some models have the ability to adjust the speed. Despite the fact that the jigsaw can cut different thicknesses of the workpiece, the saw blade stroke remains short. And if you constantly cut 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, since its blade is very thin. Some models have a different size tension adjustment mechanism. There is a guard on jigsaws, it is necessary in order to prevent contact of fingers with the file. This is usually a simple transparent plastic screen, but if the workpiece feed is correct, the guard may not be needed. In addition, when working, you must have a clamping device with you - it is required to prevent vibrations, since the workpiece can rise from the movement of the web. In good and high-quality machines, a tube for cleaning from sawdust is provided at the back of the blade. Air is supplied under pressure through this tube, which blows away all the debris along the marking line.
A homemade jigsaw can be used for some homework, for example, for making homemade furniture, decorating various buildings and interiors, cutting wood patterns, etc. In order to make a machine at home, you canuse 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 sewing machine motor 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, assemble and mount it, and check the safety of its operation.
