Jigsaw and features of its components
Among numerous ways of decorating wood products, a significant place belongs to carving. Over time, the simple application of serifs and dots to the surface of wood has evolved into a real art with numerous varieties of execution. Although in fact experts speak of three main types of work with wood: flat carving, relief and wooden sculpture. And the varieties of each of the three are distinguished from five or more. And each requires its own special tool.
The most common are hand-held jigsaws. But there are also electric, equipped with a special working table and a spring top attachment of the nail file. Figured sawing by hand is still more common. The tool frame on the free ends has screw terminals of the file holder. Round wooden handle is strengthened under the bottom clip, quality jig saws above the upper clamp have a special tension screw. If the frame of the jigsaw is made of wood, then such a screw is required.
Poorly stretched nail file will not allow you to cut out jig saws qualitatively, and saw blade will quickly break. A special article that influences the quality of the work performed is the nail file. These narrow and thin steel strips with denticles on one side can be of ten standard sizes( numbers).The rooms differ in the thickness of the canvas, the size of the denticles. The smaller their size, the more delicate sawing can be done. The lengths vary from eleven to thirteen centimeters.
We prepare the tool and work place
The correct sawing with a jigsaw is possible with a tightly stretched nail file fixed with screw terminals. Properly inserted nail file has the direction of the teeth forward and down. This is easily checked by touching your fingers. In the process of work, in addition to the jigsaw itself, you will need an awl, a small drill( preferably a manual drill) with a set of drills, a sharp awl with a wooden handle, a set of nail files and abrasive( sandpaper) skins, a pencil. To transfer the selected pattern to the wood, a special copy paper is suitable.
Most often, carved items are cut with a jig saw from plywood( as laminated wood) or thin boards. For convenience of work, in addition to the above tool, you will need a set( 3-4 pcs.) Of clamps, a work table "dovetail" from a tablet of centimeter thickness of solid wood. The oblique cutter-knife, straight and semicircular chisels will help to fine-tune the thin elements.
Preparation of the workplace before working with a jig saw, consists in fixing the rectangular part of the table of the "swallowtail" to the edge of the table top or workbench with two clamps. In this case, the working cutout of the "tail" hangs over the edge of the table top and faces outwards. To it can be fastened( also clamps) a preparation with the transferred drawing. The sawing is done in the cutout of the "tail", the jigsaw moves up and down. The fillet is located vertically.
Learn how to saw saws
So, you need to know how to cut saws properly. If the preliminary recommendations for installing the nail file are fulfilled, then it only saws when it moves down. In this phase, you need to lightly push forward, moving it along the line of drawing. It is important to monitor the vertical movement of the nail file, do not allow slopes.
An important point, showing how to work properly with a jigsaw, is the skill of turning the workpiece, not jigsaw. This is an important feature and must be strictly observed. The steeper the pattern line, the slower and more carefully you need to cut.
Separately, tell us how to use the jigsaw, if you need to cut internal closed circuits. If there are such, the work on carving is started with these contours. To do this, a through hole is made from the inside along their edge, closer to the contour line, the edge of which does not protrude beyond the cut outline. For thin plywood, you can use an awl, for thick plywood and an array of boards it is better to use a drill and a drill of the desired diameter.
One end of the nail file is released from the clamp, threaded into the hole and clamped again, providing the desired tension. Care should be taken during this procedure to avoid breaking the cloth. When the contour is cut out, the nail file is released, a new hole is made in the new contour, the passing and fixing is repeated. Carved.
Only after all internal contours have been cut out, it is possible to start cutting out the outer contour. The whole process is well illustrated on the Internet with numerous videos, sawing with a jig saw continues to be a popular hobby for many. In conclusion, we recall that in the process of work, one should not get too involved and allow a strong heating of the nail file. This leads to a rapid failure. Periodically cool the working cloth.
