7. Turn off saw, allow blade to stop, and slide jig
back. Note: Do not pass jig back over a moving
saw blade.
8. Turn workpiece around and clamp in position.
Turn on saw and make second pass.
NOTE: The illustration uses a workpiece with
pre-cut cheek lines, requiring only two passes
to complete the tenon. If cheek lines are not
precut, follow the above instructions for each
side of the workpiece with fence locked, then
loosen fence lock knob (Figure 11) and move
fence in increments away from the blade, to
make multiple passes to clear away the excess
wood.
Tighten fence lock knob
before each pass.
9. Fit the tenon to your mortise.
•
If test tenon is too loose, stop #1 is too far
back; that is, fence is too close to blade.
•
If test tenon is too tight, stop #1 is too far
forward; that is, fence is too far from blade.
If adjustment is needed, it will generally be very
slight, perhaps a few thousandths of an inch. There
are two methods by which to adjust, as follows.
10.2 Adjustment method 1 (zero point
recalibration)
1. Determine amount of adjustment needed. (Use
calipers, micrometer, or similar tool for greater
accuracy.)
2. Place a shim, such as a sheet of paper of the
required thickness, between blade and fence,
and re-establish fence to blade contact, as
explained in sect. 9.4.
3. Follow the setup procedures for chisel and
workpiece, as explained in sect. 9.4 and 9.5.
10.3 Adjustment method 2 (fine adjust)
1. Determine amount of adjustment needed. (Use
calipers, micrometer, or similar tool for greater
accuracy.)
2. Slide the jig clear of the saw blade.
3. Use micro adjust knob (Figure 14) to move
fence, as determined by the following:
If test tenon was too loose (i.e. stop #1 too far back):
4. Loosen fence lock knob and stop #2.
5. Slide fence handle and stop #2 until they are
firmly against stop #1.
6. Tighten fence locking lever.
7. Rotate micro adjust knob counterclockwise (as
viewed from front of jig) to achieve desired
distance on scale. Watch for a space to appear
between fence handle and stop #2.
8. Tighten fence lock knob.
9. Loosen stop #1 and stop #2 and slide them
together until they contact fence handle.
10. Tighten stop #1. Stop #1 has now been reset for
its zero reference to blade.
11. Loosen fence locking lever.
12. Follow the setup procedures for chisel and
workpiece, as explained in sect. 9.4 and 9.5.
13. Cut another test tenon and check for fit.
If test tenon was too tight (i.e. stop #1 too far
forward):
4. Loosen fence lock knob and stop #2.
5. Slide fence handle and stop #2 until they are
firmly against stop #1.
6. Tighten fence locking lever.
7. Loosen stop #1, making sure it does not shift
position while doing so.
8. Rotate micro adjust knob clockwise (as viewed
from front of jig) to push fence toward back of
jig, pushing the stops with it. Watch for slight
movement by checking micro adjust scale.
9. Tighten stop #1. Stop #1 has now been reset for
its zero reference to blade.
10. Loosen fence locking lever.
11. Follow the setup procedures for chisel and
workpiece, as explained in sect. 9.4 and 9.5.
12. Cut another test tenon and check for fit.
