Using the Four-Jaw

Chuck

To install the four-jaw chuck:

Refer to the Mounting the Chuck and Faceplate procedures on Page 17 to mount the four-jaw chuck.

To load a workpiece in the four-jaw chuck:

1.DISCONNECT POWER TO THE LATHE/ MILL!

2.Using the chuck key, open each jaw so the workpiece will lay flat against the chuck face.

3.Support the workpiece.

4.Lock the tailstock and then turn the tailstock quill so the dead center makes contact or is close to the center point of your workpiece (see Figure 14).

Figure 14. Clamping workpiece.

5.Turn each jaw until it just makes contact with the workpiece.

6.In an opposing pattern, tighten each jaw in small increments. After you have adjusted the first jaw, continue tightening the opposing jaw. Check the dead center alignment fre- quently to make sure you have not wandered off your index point due to applying too much pressure to a single jaw.

7.After the workpiece is held in place, back the tailstock away and rotate the chuck by hand. The center point will move if the workpiece is out of center.

8.Make fine adjustments by slightly loosening one jaw and tightening the opposing jaw until the workpiece is precisely aligned. Use a dial indicator for fine tuning adjustments in align- ment (see Figure 15).

Figure 15. Centering workpiece.

9.Use a lower RPM when machining heavy eccentric workpieces.

Securely clamp your workpiece and remove the chuck key! Thrown objects from a lathe/ mill can cause serious injury or death to the operator and to bystanders many feet away.

Another noteworthy characteristic of the Grizzly G0492 is its user-friendly design. The machine includes a built-in digital thickness gauge that allows for precise adjustments, ensuring consistent thickness throughout the sanding process. This not only saves time but also minimizes the risk of damaging the workpiece.

Additionally, the G0492 is equipped with a dust collection system that efficiently captures sanding debris, promoting a cleaner workspace and enhancing air quality. This feature is essential in maintaining a safe and comfortable working environment, which is often overlooked in woodworking.

Durability is a hallmark of Grizzly tools, and the G0492 is no exception. Constructed with heavy-duty steel frames and components, this dual-drum sander is designed to withstand the rigors of daily use.
