Making Adjustments to 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 0° tilt and 45° tilt. The difference in those measurements is proportional to the non-
parallelism 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. 47. You will also need a 6 mm hex L-wrench (a “stubby” hex L-wrench works best).
First, align the table as described on page 46, using the precision alignment procedure. Make sure the non-
parallelism between the miter slot and the blade is as close to zero as possible. If the final parallelism is not
zero, write down the misalignment, including whether it is positive or negative. This is the first measurement
for this procedure.
Next, move the dial indicator measurement arm off the blade and tilt the blade to approximately 45°. Make sure
not to tighten the tilt hand wheel against the 45° limit stop. Now reposition the dial indicator measurement arm
against the right side of the blade and about 1 /
4
inch directly above the arbor flange. Slide the dial indicator
mount toward the front of the saw until the measurement arm is about 1 /
2
inch inside the front edge of the
blade. See Fig. 58. Set the dial indicator readout to zero.
Slide the dial test indicator mount smoothly
toward the back of the saw until the
measurement arm is about 1 /
2
inch inside
the rear edge of the blade. Note the reading
of the dial indicator as the mount moves
across the blade. Write down the final
number, including whether it is positive or
negative. This is the second measurement
for this procedure.
Now take the difference between the
first measurement and the second
measurement. If one measurement is
positive and the other negative, make sure
to take the full difference. For example, if the
first measurement is +0.002 inch and the
second measurement is -0.004 inch, then
the difference is 0.006 inch. Write down the
difference between the two measurements.
This number is proportional to the non-
parallelism between the blade and the tilt
axis.
If the difference is 0.002 inch or less, then
the blade is parallel to the tilt axis within the margin of error for this procedure and no further alignment
is necessary. For differences larger than 0.002 inch, you can adjust the angle of the blade to improve the
parallelism between the blade and the tilt axis. The adjustment must be made at a 0° tilt angle.
