- Use a square to keep lines straight
Making Straight Cuts
Set the miter saw blade at 0 degrees for straight cuts. Keep the trim firmly against the fence.
Cut slowly to avoid splintering the wood. Use a sharp blade for cleaner edges.
- Align the blade with the pencil mark
- Hold the trim tight to prevent movement
- Cut at a steady speed
Executing Compound Cuts
Compound cuts combine miter and bevel angles. These cuts fit trim around corners and angled walls.
Adjust the miter and bevel settings on the saw. Test cuts on scrap wood help avoid errors.
- Set miter angle for horizontal tilt
- Set bevel angle for vertical tilt
- Check angles with a protractor if needed
- Practice on scrap before cutting trim
Handling Crown Molding
Crown molding requires special care. It sits at an angle between the wall and ceiling.
Place the molding upside down on the saw. Match the molding’s spring angle to saw settings.
- Identify the spring angle of the molding
- Use the saw’s crown molding setting
- Hold the molding tight and steady
- Make test cuts on scrap pieces
Common Mistakes To Avoid
Using a miter saw for trim work needs care and attention. Small mistakes can cause big problems with your cuts.
Learn about common errors to keep your trim cuts clean and precise every time.
