2. Loosen lock handle, rotate indexing guide to
desired bore spacing shown on scale, then
tighten lock handle to secure setting (see
Figure 24).
Note: Indexing guide clicks into position on
each row of indexing holes.
3. Attach workpiece to table, then adjust table
stops for boring operation (refer to
Adjusting
Table on Page 22).
4. Rotate lock pin clockwise and move table
to seat pin in desired indexing hole (see
Figure 24) to lock table in position for drilling
operation.
5. Move table and workpiece away from bit,
then turn machine
ON.
6. Use feed handle to slowly move table and
workpiece into bit to drill first hole, then move
table and workpiece away from bit.
7. Pull lock pin out, then move table sideways
until lock pin seats in next indexing hole.
Repeat
Steps 6–7 until index drilling opera-
tion is complete.
8. When complete, disconnect machine from
power and remove workpiece.
3. Pull lock pin out and rotate it 90° clockwise to
disengage indexing guide (see
Figure 25).
5. Repeat Step 4, moving workpiece into bit in
1

" increments until all material is removed to
measured depth.
6. When complete, disconnect machine from
power and remove workpiece.
Boring Workpiece
Freehand
When the indexing guide is disengaged, this
machine can be used "freehand" by the operator
to perform a wide range of slotting and boring
operations, making it ideal for slot mortises and
other loose tenon joinery.
To bore a workpiece freehand:
1. Measure and mark workpiece, then install
selected boring bit into chuck.
2. Clamp workpiece to table and adjust table as
necessary for workpiece operation (refer to
Adjusting Table on Page 22).
4. Use feed handle to align bit with one outer
reference mark and feed workpiece no more
than
1
⁄
16
" into bit, then move workpiece across
bit to remove material between reference
marks (see
Figure 26).
