Graduated Dials
SECTION 6: ADJUSTMENTS
The graduated dials on the handwheels for the
table and fine feed can be indexed or “zeroed” to
help make accurate and convenient movements.
Each dial can be reset or locked with the
setscrew or thumb screw provided.
Example:
Suppose you want to drill a series of holes
in a workpiece at 0.625" centers. After
locating the first hole’s placement and
drilling, you can set the dial of the appropri-
ate axis to zero and move the table 0.625".
Drill the next hole and proceed as above.
3. Loosen the setscrew on the knurled surface
of the handwheel dial. Turn the dial until the
“0” lines up with the index line. Tighten the
setscrew.
4. Turn the handwheel according to the dis-
tance you want to move downward. Each
complete revolution equals 0.100".
Locking:
For milling operations, the spindle height
can be locked in by tightening the black
lever on the forward, right hand portion of
the head.
You have two options for spindle height adjust-
ment: a drill press style, levered downfeed and a
micro adjustment handwheel. The lever is located
on the right, forward portion of the head. The
micro adjustment handwheel is to the left.
To operate the feed lever:
Pull the lever toward you. The spindle will go
down until you stop pulling or until it hits the depth
stop.
To operate the micro-adjustment handwheel:
1. Tighten the knurled locking knob located on
the left side of the headstock and just
behind the fine downfeed handwheel.
2. Locking out the levered downfeed will
transfer control to the handwheel. The
handwheel will not function if the knurled
locking knob is loose.
Spindle Height
To calibrate the depth stop:
1. Roll the quill down using the lever handle
until you reach the desired depth shown on
the scale. Lock the quill with the lever lock
handle. Turn the depth stop nut until it
meets the bottom of the depth stop block.
Tighten the jam nut against the bottom of
the stop nut.
2. Roll the spindle up into the head. Place a
piece of paper on the workpiece. Loosen
the knee lock handle and raise the knee
until the drill bit or cutter just touches the
paper. Tighten the knee lock.
3. Begin drilling or milling. Note for precision
depth: set the depth stop shallow of the
desired depth by
1
⁄16''. Drill the hole and
measure. Finish to depth using the fine
downfeed handwheel with its graduated
dial and use the procedure laid out in the
section above titled: Graduated Dials.
