How To Make Straight Line Cuts Using a Jig Saw

Making somewhat of an involved cut, jigsaws can be a bit intimidating when faced with cutting a straight line. A material’s density can affect the type of blade one uses, and thus, the ease with which the cut can be made.

Step 1: As you already know that you intend to make a straight cut, your first step will be to determine what type of blade you plan to use. As was mentioned previously, much of this decision depends on the type and density of material you will use. The components of the cut vary directly, meaning that a slighter object requires a blade with finer teeth.

Step 2: After a blade is chosen and you have your materials set up, it is critical that you use a pair of safety goggles or something comparable. Trying to make a straight cut for the first few times can be nerve-racking enough without worrying about bits of scrap metal or wood colliding with your eyeball.

Step 3: Visible cut lines can be very helpful in determining where to guide (or at least start out) the blade. The “shoe,” or the base of the jigsaw, should be placed at the beginning of the cut mark. You may want to position the shoe slightly to the side of the cut line for a practice run.

Step 4: Making sure you have the jigsaw firmly in hand, flick the power on and begin cutting. If you are uncomfortable or unsure of yourself, stop cutting and readjust either the materials or your position. Place the shoe of the jigsaw at its initial angle and start your cut again. If you are still having problems, a straight edge guide may be helpful in serving the exact purpose it states in its name.

Step 5: Be careful not to bear down on the jigsaw or material when you are making your cut. An application of pressure can be detrimental, in that it may cause the blade to break off. To an extent, it is necessary to let the jigsaw guide your hand.

When making straight line cuts with a jigsaw, it can also be helpful to keep in mind several tips. The depth of the material being used should be taken into consideration. A measurement of 1 ½ inches deep is the maximum amount that the jigsaw can easily cut through, for most materials. A sharp blade is also beneficial, in that it will prevent excess work on your part and will provide swift, smooth cuts. If you are not already familiar with jigsaws, practicing a few cuts will get you to the point where you are comfortable with them. Keeping these steps in mind, you are ready to use your jigsaw to make a straight line cut.
