Position the Stop Collar
a. Place the step bit (G) in the setup gauge
on the jig base, aligning the step shoulder
with the dimension mark that matches
the thickness of your workpiece. Slide the
stop collar (H) onto the end of the bit and
position it against the end of the stop-collar
recess. Tighten the stop-collar set screw
with the hex wrench (I).
4
Adjust the Clamp Pad
a. Advance the toggle clamp (C) to the fully-clamped
position. Loosen the jam nut by rotating it on the
threaded clamp rod. Place your workpiece against
the drill guide. Rotate the clamp pad (D) until it is
pressing against the workpiece. Move the toggle
clamp handle to the unclamped position. Rotate
the clamp pad (D) another 1-1/2 to 2 turns to
advance it closer to the workpiece. Advance the
toggle clamp (C) to the fully-clamped position to
test that adequate clamping pressure prevents the
workpiece from moving.
