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.

Spindle Height

You have two options for spindle height adjustment - 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

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.

Depth Stop

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.
