Aligning the Blade to the Tilt Axis

When making bevel cuts, the blade is tilted on an axis that runs along the surface of the table between the
front and rear trunnion brackets (see Fig. 105). If the blade is not parallel to this axis, the blade will move out of
parallel with the miter slots when it is tilted away from 0º (this assumes the table has been aligned to be parallel
to the blade at 0º tilt angle). SawStop
the parallelism of the blade to the tilt axis.
NOTICE! This alignment procedure is not intuitive. Make sure you read this
entire procedure before beginning and follow each step precisely. Any deviation
from this procedure may create a substantial misalignment in your saw.
The geometry involved in this alignment procedure is tricky. That is because there is no way to easily measure
the parallelism between the blade and the tilt axis. Instead, you must measure the alignment between the
blade and the table at both 0º tilt and 45º tilt. The difference in those measurements is proportional to the
misalignment between the blade and the tilt axis. To ensure accurate alignment, follow the procedure described
below exactly.
To align the blade to the tilt axis, you will need a dial test indicator with a resolution and accuracy of at least
0.0005 inches, and a mount for the indicator that will slide smoothly in the miter slots. An example of a suitable
mount is shown in Fig.
coated with paint or similar materials that may affect the measurement. Attempting to align the blade to the tilt
axis using a blade that is not very fl at will cause similar inaccuracy in the alignment.
First, align the table as described on page 63, using the precision alignment procedure.
