SECTION 6: 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 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 appropriate axis to zero and move the table 0.625". Drill the next hole and proceed as above.
Spindle Height
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
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.
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.
Depth Stop
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.
