How to use a jig saw power tool

A jig saw is made up of a saw blade and an electric motor. A stand is provided on which the material is placed, and the jig saw blade is moved up and down to cut objects. It is suitable for cutting in curves and is also used for cutting out wood.In this article, we go through the uses of a jig saw and alsodiscuss how it can be used to process materials safely.

Jig saw power tool applications

A jig saw tool is useful for cutting materials in precise curves. It can cut in the finest curves of any power tool and is used for creating smooth curves. Jig saws can easily cut delicate lines that cannot be cut with a saw. 

Jig saws have a vast number of applciations. Typical examples of products that use a jig saw are stenciled designs and letters. Other applications include smoothing the edges of woodwork.

It is also a useful tool for a variety of other applications, such as framing windows and mirrors, and inlaying different colored materials by overlapping and fitting them together. It can cut wood up to 50 mm, brass and aluminum up to 1 mm, and plastic up to 5 mm.

When the switch is turned on, the saw blade moves up and down like a sewing machine to cut the material. It is important to select a blade that matches the material to be cut. It can cut thick materials such as wood as well as thin materials such as plastic and metal. Wood saws have fewer blades, metal saws have finer blades, and plastic saws are somewhere in between. Jig saws have a larger throat, which is the distance from the saw bow to the blade, and can cut larger materials than hand saws. The size of the saw blade should be a little larger than the material to be cut.

Place the material to be cut on the board, apply the blade to the part to be cut, and feed the material out. The basic cutting method is to place the material on the board, turn on the switch, place your hands on both ends of the material, and slowly feed the material once the vertical movement of the blade is stabilized. The material will bob up and down as it is cut, so press down from above to push the material out the other side.

For cutting in the middle, use a drill or a miller to drill a preliminary hole about 2 to 3 mm in size first. Remove the blade from the arm and lift up the arm only. After passing the blade through the hole and setting it on the board, put the arm back and set the blade on the jig saw machine before cutting.

If you are right-handed, set the curve so that the material is turned to the left, and twist and turn the right hand while holding the center of the part to be cut with the left hand. If you use a two-handed operation, it is easy to get confused and you may end up with a parallel line. For a meandering line, it works well to cut a little at a time, taking a breath with each twist. For right-handed curves, hold the left hand in place and move the right hand.

If the cut surface is disturbed, sandpaper it. Sharpen the thin board along the cut edge, as it is prone to cracking when applied vertically. When cutting a thin board, it is better to pinch it with a piece of scrap wood before cutting to prevent the edges from cracking.

The cutting surface can also be slanted by tilting the board. Loosen the fixing screw about halfway and adjust the angle by aligning it with a protractor. The most precise process of inclined cutting is inlaying, which is a method of overlapping two pieces of material of different colors and cutting them at an angle to make use of the pattern on the same side. Since the board can only be tilted to the left, cut the materials in a counterclockwise direction; when the two boards are cut, fit them apart and glue them together if they fit. Finally, sand the surface with a sander or sandpaper until it is flat.

Summary

The jig saw power tool is a tool that can be used in a wide variety of situations, not only for straight cutting, but also for cutting solitary lines and cutting surfaces at an angle. If you learn how to use it correctly, you will be able to cut with smooth and precise lines, resulting in a higher degree of perfection. By understanding the basics of how to use the jig saw tool, you can cut with clean lines.
