About Miter Saw Protractor?

How To Use?

To cut crown molding bevel angles without installing a jig on a miter saw table, with the protractor held in place (by turning the nut), turn it over to see the reverse side and check the measurements indicated by the arrow. In the case of a 140° angle, the arrow points to 14.4° and 14.0°.

In this case, adjust the miter saw table angle to 14.4° and the bevel angle to 14.0°. Place the crown molding flat on the table (after double-checking whether this is to be a right- or left-side cut) and make your cut.
