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 2-24.
The quarter scale hasTwo 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.
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.
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. Loosen the wing nut on the left end of the indicator. Move the indicator until one of the
red dots is on the nearest 4/4 mark. 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.
