Pitch angle information – The top section of the miter scale shows angle settings required to
cut roof rafters to the "Pitch Angle" system. 2/2, 4/12, 6/12, etc., are all pitch angles. This system
is based on using the English "inches." A 6/12 pitch angle roof equals a ratio of 6" "rise" for every
12" "run" (see Figure 45).

Crown molding information – There are miter position settings for compound-cutting crown mold-
ing flat on the table. Crown molding with 38° "spring angle" uses the 31.6 setting (with detent)
and crown molding with 45° "spring angle" uses the 35.3 setting. NOTE: This cutting method also
requires that specific bevel angles are set – see Cutting Crown Molding on page 50.
