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" (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
See Table 3-2. The quarter scale contains 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.
To choose which scale to use, determine what finished thickness you want to end up with.
The Grade Hardwood Quarter Scale provides thicker finished boards usually required by
commercial buyers. The Standard Quarter Scale allows for kerf and shrinkage of finished boards
suitable for most custom applications. Always check with your customer before you saw to
determine what actual finished thickness is required.
To use the quarter scale, look at the blade height indicator. Example: You want to cut 1" (25 mm)
(4/4) random width boards from a log. Position the blade for the first cut. Make a trim cut. Return
the carriage for the second cut. Now, instead of having to measure down 1 1/8" (29 mm) on the
inch scale, you can simply lower the blade so the indicator is aligned with the next 4/4 mark on the
quarter scale. Turn the log 90 degrees and repeat.
