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. Line up the horizontal red line on the
indicator with the nearest mark on the scale you want to use. Make a trim cut. When you return the
carriage for a second cut, lower the carriage to the next mark on the scale. This mark shows where
the blade should be positioned to cut a certain thickness of lumber, 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. Adjust the quarter scale so a 4/4 mark is aligned with the red line on the indicator. 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.
