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 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
The magnetic quarter scale has four sets of marks. Each set represents a specific lumber thick-
ness. Saw kerf and shrinkage allowance are included, but actual board thickness will vary slightly
depending on blade thickness and tooth set.
See Table 5-1.
To use the quarter scale, look at the blade height indicator.
Position the magnetic quarter scale over the inch scale. Align one of the quarter scale marks with
the horizontal line on the indicator.
