Miter Cuts With The Chop Saw

The process is known, after the new laminate or parquet was laid on the floor or in the party room, the ceiling area was given a panel cladding.
Now you are faced with the task of ensuring a clean cut of the skirting boards. Miter cuts are essential. How are they carried out correctly?
It’s easier than expected if you have the perfect tool and take a few steps into the making.


Cutting ceiling and floor moldings

Skirting boards provide a bridge from the floor to the wall. In most cases, the strips are attached to the wall. For the assimilation of the baseboards on the butt edge, a miter cut is usually made . The corners normally have an angle of 90 degrees . That is why the miter cut is made at a 45 degree angle.
The upright formation of the strips on the wall is characteristic. As a rule, the miter can be formed by a miter cut, however, due to the vertical position of the strips, only a limited cutting height is possible.
The miter can be formed more effectively by means of an incline cut. During this process, the bar is just on the saw table . You can clamp the bar more easily, the width of the cut is more voluminous and the quality of the cut a little better.

Creation of diagonal ceiling and floor moldings

Often in old buildings you will find ceiling and floor moldings that have been attached diagonally as a transition to the wall ceiling or wall floor. A combination of a miter and bevel cut is necessary to create the edges. It is known as a double miter or shift cut .

Step 1: Selection of the last angle

As the basic basis for the precise miter cuts diagonally existing ceiling and floor moldings are strip angles . These determine the change from the strip to the wall, to the ceiling and to the floor.

Step 2: measuring the corner angle

The following significant measure is the corner angle. This can represent an inside angle or an outside angle. According to claims, the “right” angle on the building is between 80 degrees and 100 percent . You always have to be prepared for the fact that corner angles can actually achieve a deviation of 90 degrees. At these right angles, other corner angles in the form of attractive wall cladding, built-in furniture or balcony projections can also occur.
The same procedure requires the trim of decorative strips on furnishings. Ideally, you should use a digital protractor for measurements. The device delivers the most precise results for the miter cuts and reading errors are excluded. In this example, a corner angle of 92 degrees was selected in a practice-oriented manner.

Step 3: Determine the miter and inclination angle

For the true-to-profile transfer of the cut edges, you have to cut the strips with a miter and also with an incline. The miter angle and the inclination angle are determined on a mathematical basis. However, the expenditure is too high and it is more comfortable if you use a table. The Internet offers help immediately.
The work is simplified if you use an experienced Bosch protractor. In its microprocessor you will find the storage of the miter and inclination angles. After the corner angle has been measured, the required values are automatically shown at the push of a button. With an existing corner angle of 92 degrees, the protractor calculates a miter angle of 34.3 degrees and an angle of inclination of 29.4 degrees at a last angle of 45 degrees / 45 degrees. You can continue your work with the knowledge of the miter and inclination angle.

Step 4: adjust the saw table

After determining the miter and tilt angle, the two data are aligned and fixed to the left by scaling the turntable and scaling the tilt setting. The precision of the transition depends on the exact setting and must be handled very carefully. Adjustments after the decimal point are very difficult. You have to take the measures as precisely as possible in order to make a few attempts at cutting before finally cutting the last with a sample in order to be able to make any changes.

Step 5: the capping

The first thing you do is cut the bar. Place them on the saw table from the left with the decorated surface facing up. After putting on, cut the bar. Then the same calibrations from step 4 are carried out, but with the miter and inclination to the right. Then place the second bar from the right and with the decorated side up on the saw table and cut the bar.


Due to the necessary precision, the adjustment of the miter angle and inclination is very demanding. For each new adjustment, you have to complete a few control cuts as a test. You can exclude the expense if you do not change the left setting according to step 4 and create the second bar from the left again. In this case, the decor side is at the bottom.
