Precision Miter Gauge
Setting the miter gauge angle
Referring to Figure 19:
The precision miter gauge has a rack and pinion
adjustment for setting the angle. To operate:
1. Slide the miter gauge into one of the slots on
the table top.
2. Loosen lock handle (A).
To adjust the body (B) of the miter gauge to the
desired angle:
3. Pull the spring-loaded knob (C) out and turn
until the body (B) of the miter gauge is at the
desired angle as indicated on the scale.
4. Tighten the lock handle (A).
Indent settings
There are indents at the 0º, 30º and 45º right and
left positions. At these settings, release the
knob (C) to engage the stop rod. Then tighten the
lock handle (A).
Note: Do not rely solely on the indents for an
accurate setting. After the stop rod engages at the
0º, 30º and 45º positions, make a fine adjustment
with the knob (C), if necessary, setting it against
the scale indicator.
Extension plate
The extension plate (D) can be adjusted by sliding
to the right or left or removed entirely.
To adjust – loosen two lock handles (E), position
the extension plate and tighten the lock handles.
To remove – slide the extension plate completely
off and remove the lock handles (E) and mounting
hardware.
Calibrating the miter gauge
1. Place the miter gauge in one of the slots (H) on
the table top.
2. Set the miter gauge to 90º (0º setting on the
scale) by loosening the lock handle (A), then
pulling the spring-loaded knob (C) out and
turning the body (B) until 0º is indicated on the
scale (F).
3. Measure the accuracy of the gauge against the
slot with a combination square.
If adjustment is necessary:
4. Adjust the body (B) until it is perfectly square
(90º) to the miter slot (H).
Figure 19
5. Tighten the lock handle (A).
Verify that the scale indicator (G) reads 0º. If further
adjustment is necessary:
6. Loosen the screw (F) and adjust the
indicator (G) until it reads 0º
7. Tighten the screw (F).
The miter gauge should fit snugly within the miter
slot while still sliding easily. The bar of the miter
gauge has two slots, each with a set screw. Rotate
one or both of these set screws with a hex wrench
as needed to eliminate any play between the miter
gauge bar and miter slot.
