SETUP & OPERATION
3.13 Blade Height Scale
See Figure 3-16.
The blade height scale is attached to the cutting head frame. It includes:
a blade height indicator
an inch scale.
Blade Height Indicator
The blade height indicator has two horizontal, red lines on both sides. Readings should be taken with
eyes level with the indicator, when the two red lines are in line. This will allow to avoid the parallax
error (different scale readings depending on the angle of vision).
The Inch Scale
The horizontal red 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” (28 mm) below the original measurement. (The extra
1/8” (3 mm) allows for saw kerf and shrinkage of the lumber.)
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.
The Quarter Scale
See Table 3-2.
Two quarter scales are provided with four sets of marks. Each set represents a
specific lumber thickness. Saw kerf and shrinkage allowance are included, but actual board
thickness will vary slightly depending on blade thickness and tooth set.
