A Perfect Crown Molding
with your Starrett 505A-12
1) Measure the corner angle near the ceiling. Note
the Miter Cut value from the dial (inner scale).
2) Determine the spring angle (information available
where you purchase your crown molding stock).
3) Refer to the compound cut conversion table (see back).
Locate the row with the same "Miter Cut" value as your corner measurement.
4) Note the "Miter Angle" and "Bevel Angle" from the row that corresponds
to the spring angle of your work piece stock (38° or 45°).
5) Refer to the table below and carefully set the miter angle and bevel angle on
your compound miter saw, then position your work piece with reference to the
blade and fence, as indicated. Then, cut your first work piece.
6) Reset the saw and position your second work piece as indicated by the
table below. Then, cut your second work piece.
The two work pieces should align perfectly for your crown molding.
