Blade Height Scale
See Figure 4-9.
The blade height scale is attached to the carriage head frame. It
includes:
a blade height indicator
an inch scale
a magnetic quarter scale (after 3/99)
The Inch Scale
The horizontal line on the blade height indicator shows how many inches the bottom of
the blade is above the bed of the mill. If you know the height of your blade at each cut,
you can determine the thickness of lumber you are sawing.
Example:
You want to cut 1" (25 mm) random width boards from a log. Position the blade
for the first cut. Move the carriage to an even measurement on the inch scale. Make a
trim cut. Return the carriage for the second cut and lower it 1 1/8" (29 mm) below the orig-
inal measurement. (The extra 1/8" (3 mm) allows for saw kerf and shrinkage of the lum-
ber.)
The yellow area on the scale identifies where the blade could encounter a side support or
log clamp. Check that these items are below the blade level before sawing.
