Quarter round is a piece of finish lumber that is generally thin with one 90-degree angle and a rounded side the length of it. It is used in a variety of finish construction such as doorways, counter kickboards and cabinets as well as furniture and other wood crafts. Quarter round has also been used for framing artwork and prints. Quarter round can be easily and accurately cut with a miter saw.
Place your piece of quarter round on your miter saw table so that it is on one of the two flat sides with the round side facing you.
Measure the length you need your quarter round to be along the rounded side from left to right. Mark it with your pencil on the top edge where the round side meets the flat edge.
Put on your safety goggles and insert your ear plugs.
Slide your piece of quarter round up against the saw fence, still with the rounded side facing you.
Lower the blade so that it almost touches the quarter round (do not start the saw).
Move your quarter round until the right side of your pencil mark just touches the teeth of the blade facing more to the left.
Raise the saw blade back up. Place a C clamp on the quarter round on each side of the saw to secure it (quarter round has a tendency to flap when being cut) and tighten it. Make sure you keep the handle of the clamps behind the fence and do not over tighten the clamp or you will mar the surface of the quarter round.
Start the saw and pull the blade down all the way through the quarter round. Raise the blade back up and release the trigger on the saw to stop it.
