SECTION 5: ADJUSTMENTS
Graduated Dials
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 set-
screw or thumbscrew 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 appropriate axis to zero while
holding the handwheel. Move the table 0.625".
Drill the next hole and proceed as above.
You have two options for spindle height adjust-
ment - a drill press style, levered downfeed and a
micro adjustment handwheel. The three levers
are located on the right, forward portion of the
head. The micro adjustment handwheel is on the
front right hand side of the head.
To operate the feed lever:
There are 3 levers with knobs located on the right
side of the headstock. Pull the lever nearest 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 locking knob located on the
center of the hub for the down-feed levers.
2. Locking out the levered downfeed will
transfer control to the handwheel. The
handwheel will not function if the locking
knob is loose.
3. Loosen the setscrew on the rim surface of
Spindle Height
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 lever on the for-
ward, left hand portion of the head.
The depth stop is used to control the range of
downward movement by the drill bit or cutter.
Maximum depth is 5".
To calibrate the depth stop:
1. Make sure the spindle is drawn all the way
up into the head. Place a piece of paper on
the workpiece. Loosen the headstock bolts
and lower the head until the drill bit or cut-
ter just contacts the paper. Tighten the
headstock bolts.
2. Turn the depth stop leadscrew until the top
of the indicator plate is level with your
desired depth as listed on the scale to the
left or right. The depth stop leadscrew is
controlled by the knurled knob under the
front of the headstock.
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
Graduated Dials above.
