CAT Length Adj – This adjustment is for the unique
circumstance of single bevels on both ends that are
parallel to each other that occurs when cutting CATS
(ller members at the pitch break between step down
hip trusses).
Adjustments with LEADING and TRAILING Data - A
“90 Deg Bevel” refers to a bevel on a square cut end on
one end (like the bottom chord of a hip jack). A “Non-90
Deg Bevel” refers to a bevel on one end with a plumb
cut (like the top chord of a hip jack).
These adjustments only apply to pieces with a bevel
(single or double) on them. The length adjustments
control the overall length of the piece and the centerline
(CL) adjustments control the bevel centerline on the
thickness of the lumber for double bevels. LEADING
and TRAILING are for bevels on the front or back ends of
the board as it goes through the saw. Positive/negative
numbers make the length longer/shorter and the CL
higher/lower. The location of the CL is measured from
the bottom of the board as it goes through the saw.
Sngl Bev Back Face Len Adj – An adjustment for the
length of a piece with a single bevel where the bevel
face is on the back (or bottom) as the piece goes
through the saw. “Front Face” is the same adjustment for
a front (or top) bevel.
Rip Valley Length Adj – Adjusts the length of a piece
with a bevel rip along the long side dimension. It would
be best to check this length using a ripped valley
piece with a butt cut on both ends – even if you don’t
normally cut these pieces with butt cuts. Feather cuts
are very dicult to measure accurately.
Rip Valley Oset – Allows you to control how deep the
rip is set on the piece. Normally, the saw will rip these
pieces so that the eased edge of the lumber is still on
the piece after the rip. If you want it to rip deeper or
shallower than that, use this adjustment.
SAVE – Make sure you save all data before exiting this
screen.
CANCEL – Exit without saving any data.

3.6.9 Bevel Options (9)
These values
allow you to make
adjustments to bevel
cutting. Begin bevel
cutting with all these
values set to 0 and
adjust only if you are
having trouble with
bevel centerlines
or overall length
of bevel pieces.
Always cut three
or four like pieces
before deciding
about the amount of
adjustment. Warped
lumber can signicantly aect both centerlines and
overall length of bevel pieces. Be very careful that you
select the adjustment you need to make, and that you
keep track of the bottom and top of the board. It’s
easy to get confused with this process. Get help if you
need it.
Bevel Spacing – Controls the amount of space between
pieces when they are laid out on the stock where at
least one of the pieces has a bevel condition. Leave this
value at 0 unless you are having trouble with bevel cuts
that encroach on adjacent pieces.
Floor Web Length Adj – These adjust the overall length
of a member that has a double bevel on both ends. The
“plunge” adjustments are for members that are long
enough that all four bevel cuts use the plunge cutting
process. Shorter pieces will require one of the bevels to
use the “sweep” cutting process.
