▶ Miter Cuts
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
molding 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.
