Setting the Power

Feed Rate

The carriage has longitudinal and cross slide power feed capabilities. All directions reverse when spindle rotation is reversed.

NOTICE

Feed rate is based on spindle RPM. Pay close attention to the feed rate you have chosen and be ready to disengage the apron. Failure to do this may cause the carriage to crash into the chuck.

To set and engage the power feed:

1.DISCONNECT THE LATHE/MILL FROM POWER!

2.Refer to the Change Gear Chart on Page 31 to determine the needed combination of gears and which spindle location to install each gear on. See Figure 33 for the gear installation locations that are referenced by the chart.

3.See Figure 34 for an example of gear com- binations that give the longitudinal and cross slide rates. For example: The chart shows that 0.0089" of longitudinal travel per revolu- tion of lead screw is needed, or 0.0019" of cross travel per revolution of lead screw is needed.

Note: All change gears are stamped with the number of teeth they have.

6.Move the lash adjuster so the gear backlash is at 0.003" to 0.008", and tighten the lock nut.

7.Use the leadscrew lever to select leadscrew rotation direction (Figure 35).

8.Loosen the apron lock bolt, and use the feed lever (Figure 35) to engage the cross slide or longitudinal feed.

G0492 specifications

The Grizzly G0492 is a versatile 12" dual-drum sander designed to enhance the woodworking experience for both hobbyists and professionals. This robust machine provides an exceptional combination of power, precision, and ease of use.

One of the standout features of the G0492 is its dual-drum design, which allows users to sand larger workpieces more efficiently than traditional single-drum models. This dual-drum configuration not only speeds up the sanding process but also ensures a more uniform finish. The machine supports a variety of sanding applications, making it suitable for different types of woodworking projects, from furniture making to cabinetry work.

Powered by a robust 3 HP motor, the G0492 delivers ample power to handle tough sanding tasks with ease. The variable speed control further enhances user flexibility, allowing for adjustments to accommodate varying wood types and grain patterns. This feature is particularly valuable when transitioning between softwoods and hardwoods, ensuring optimal sanding results.

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.

In summary, the Grizzly G0492 combines powerful performance, ease of use, and advanced features into a compact machine that meets the demands of serious woodworkers. Whether you are a professional working on large projects or a DIY enthusiast looking to enhance your craftsmanship, the G0492 will elevate your sanding experience, making it a valuable addition to any workshop.
