Jigsaw making technology
Choice file for jigsaw.
The main elements that make up the jigsaw (thermo jigsaw) are:
- frame (as the main structure);
- heating thread;
- push-button elements for on and off;
- clamps (screw);
- insulation washer;
- electricity supply cord.
To make a frame, take a pipe (preferably from duralumin) with a diameter of not more than 0.12 cm. If you cannot pick it up, you can use thick plywood or textolite, the thickness of which is not less than 1 cm. Your task is to make the lightest frame to use jigsaw was easy. When making the frame do not forget about the channel in which the cable will be laid. The best form of the frame is a frame in the shape of the letter “P” with a tilt angle of 45 ° C on one side.
The earring is made of copper, the thickness of which is 0.1 cm. It is fastened with screws, where the handle and the frame are connected. The heating thread is fixed with a wing nut and a screw, which are a kind of clamp. Using duraluminium not more than 0.8 mm thick, make clamping cheeks. There set the elements off.
Scheme homemade jigsaw.
The heating thread can serve as a regular nichrome spiral from an old iron. It should be fastened between the ends of the frame with a slight tension. The operating voltage should be no more than 14 V. It is necessary to control the operation mode of the jigsaw using a rheostat.
The current consumption depends on the length and thickness of the yarn from nichrome. The current should be from 3 to 5 A, because it determines the degree of heating of the thread. Before you start working with jigsaw, be sure to adjust the amperage to avoid overheating and ignition. If the current is insufficient, the cut will not, the thread may ignite.
Such a homemade jigsaw will allow you to cut complex shapes from various materials, while applying minimal effort.Back to table of contents
