The Quarter Scale
See Table 2-2. The quarter scale has four sets of marks. Each set represents a specific
lumber thickness. Saw kerf and shrinkage allowance are included, but actual board thick-
ness will vary slightly depending on blade thickness and tooth set.
An optional Grade Hardwood Quarter Scale is also available. 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 upper blade height indicator. It has two red dots.
Loosen the wing nut and angle the indicator until one of the red dots is on the nearest
mark of the desired lumber thickness scale.
When you return the carriage for a second cut, you can lower the carriage to the next
mark on the lumber thickness scale you chose, without having to measure on the inch
scale.
Example: You want to cut 1" (25 mm) (4/4) random width boards from a log. Position the
blade for the first cut. Loosen the wing nut on the left end of the indicator. Move the indi-
cator until one of the red dots is on the nearest 4/4 mark. Make a trim cut. Return the car-
riage 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.
