Using the Manual Feed Handwheels

You can manually move the cutting tool around the lathe/mill with the three handwheels shown in Figure 30.

Longitudinal Handwheel

The longitudinal handwheel moves the carriage left or right along the bed. This control is help- ful when setting up the machine for turning or when manual movement is desired during turning operations.

Cross Slide Handwheel

The cross slide handwheel moves the top slide toward and away from the work. Turning the dial clockwise moves the slide toward the workpiece.

Compound Rest Handwheel

The compound rest handwheel controls the position of the cutting tool relative to the workpiece. The graduated dial is adjustable using the same method as the dial on the cross slide. Angle adjustment is held by two hex nuts on the base of the compound rest.

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.
