Step: Measure and Mark

The initial step is to measure the square you want to cut out using a tape measure and marking out these dimensions on the wood you want to cut. Precision is vital if you want to finish a good project. Consequently, you need to capture accurate measurements so that you locate the square hole exactly where you desire it to be. You want to map out the dimensions for the square, to identify how large you need to make the square holes. If the square sits on a particular position on the wood, you need to consider these measurements as well. Now use a pencil and a square to trace the outline of the square on the wood. You want to make dark, thick lines to guide your cutting –make several passes with a carpenter’s pencil. A pencil is preferable because you can easily erase erroneous markings.

Step: Create the Pilot Hole

Before you can commence cutting with a jigsaw, you need to drill out a pilot hole to serve as the starting point for your cut. The drill bit you use should be large enough such that the jigsaw fits through the pilot hole. Once you have your outline complete, take a drill, and position it in the inner side of the square in one corner. You need to drill a hole large enough to touch two sides of the marked square. The hole you drill must not project outside the boundary lines you traced for your square.

Step: Cut Out the Square

With the pilot hole drilled in place, you are ready to commence cutting out the square. Take your jigsaw and place the cutting blade inside the pilot hole. Switch on the jigsaw and hold it firmly while you move it along the lines you traced for the square. Do not cut outside the square. It is good that you cut inside the square markings so that you do not ruin the wood in case you stray from the marking. Do not worry if the square is smaller than expected – you can widen the square using a file or sandpaper (an oscillating tool will also do the job). If you cut outside the marking and get a large square, there is no remedy other than pick another wood and start again.

Step: Smooth Finish

Once you cut out your square, it is now time to clean your work. The jigsaw will probably leave some marks and rough edges. If you are highly skilled in using the jigsaw, you may have minimal finishing work to do. However, it is common to have some uneven surfaces that require some final touches.

Use a file to clear away any rugged surfaces in the square you have just cut. You can also use a sanding wheel or an oscillating tool to remove the rough areas. Work off these imperfections slowly and keenly to avoid sanding out too much wood. This would enlarge your square, meaning you will waste your timber and end up redoing the entire process. Once the square looks smoother, proceed to finish the cleaning with sandpaper to make the square fine and smooth. Start with smooth grit sandpaper and repeat the process several times. Each time use higher grit paper until the square is perfectly flat.

Your safety

Any woodwork processes, including the use of power tools, are potentially risky and can cause injuries. It is good that you avoid small accidents such as cuts or splinters flying into your eye. Loud noises from the power tools can harm your ear. To stay safe, consider the following precautions:

Wear eye and ear protective gears before you can start your woodwork projects.

Wear fitting clothing always, avoid loose clothing – they can get entangled in a rotating machine and cause serious injuries
