1. Prepare and measure

Like other projects, you should always start with accurate measurements. To estimate a total length of a quarter round, you will need room to work by measuring the walls’ base to which you will attach the molding. Use a tape measure to get the correct length and move that measurement on the top of a quarter round and mark it with a carpenter’s pencil. Leave an extra foot if you find any error, and you may always use these scraps to get the best angles.

You have to be very careful when measuring the pieces, which assemble at the corners. They must be incised to the right direction, angle, and length so that they fit perfectly. Constantly double and also triple the measurements. The outcome of the cutting is directly related to the correct size. Keeping that in mind, you need to be as cautious and precise as possible so that the cut is accurate.

Here are the easy measurement steps to direct you through preparing a measurement.

  • Measure every piece of a quarter round and then mark the lengths on the back.
  • Start in the corner of a room.
  • When marking the materials, straighten them with a triangle or a square.
  • Draw a line on an additional piece of wood to get which way the line will be cut.
  • Mark as well as to measure the whole room this way.

Extra tips for measuring the quarter round

These are just some tips to implement and consider through the quarter round measurement process.

  • The recommended way of marking each piece is utilizing a tri triangle and a straight line.
  • Mark the vertical side line to separate the additional piece of wood. This lets you know precisely which side of a line to cut.

 2. Determine the direction and angle of cuts

Because a quarter round ends at a keystone, door jamb, or corner, it is almost acut at an angle. In most cases, this angle is around 45 degrees. For the joints, cut both parts at a 45-degree angle in the direction, which is the same. These pieces fit jointly to form the straight line on a wall.

In the corners, most are 90 degrees. In this case, cut the edges at 45 degrees but opposite. One is angled to the right and the other one to the left. It would be best to use the protractor to measure all angles that aren’t 90 degrees. After that, divide that number by two to determine the accurate angle for the cuts. If the molding ends at the doorjamb, use a 45-degree miter cut and restart a quarter round.

As important as getting the right measurement, setting the blade to the correct angle is essential. To do this, you need to place the end of a quarter round piece in the miter box.

Then it would be best if you created an end cap.

In doing this, take another scrap or small piece of quarter round and then place it in a miter box. Create the cut at a 45-degree angle, in the other direction to what you just made. Then move the angle of the miter saw to the side and make the straight cut of about 0.25 inches from the previous angle cut. Essentially, this will provide you with the end cap that fits snugly with a long piece of a quarter round.

Safety precautions to keep in mind

Because you’re using the power tool, you must be vigilant and take extra care throughout the activity.
