Sherline Resettable Handwheel Instructions

• Sherline Resettable Handwheel Instructions
• Upgrade handwheels to reset to zero easily
• Replace 1⅝” wheels with 2" adjustable ones
• Avoid using 2½” wheels on lathe leadscrew and tailstock
• Choose inch or metric versions for precision
• Install 2½” wheels with ball thrust for Z-axis

The Sherline Resettable Handwheel Instructions provide guidance on upgrading miniature machine tools with the capability to reset the handwheel to "zero" or any desired setting during machining operations. This feature, commonly found in full-size machine tools, is now accessible for Sherline's compact models. The installation process is straightforward, requiring only the release of a set screw to replace the standard handwheels. The operation involves releasing a locking nut, adjusting the red handwheel collar to "zero," and retightening the nut, allowing precise control over the feed amount without complex calculations.

The instructions detail the compatibility of various handwheel sizes, noting that standard 1⅝” handwheels can be upgraded to 2” adjustable versions. However, caution is advised against using larger 2½” handwheels on both the lathe leadscrew and tailstock simultaneously due to potential interference, though they are suitable for other applications. Both inch and metric versions are available to accommodate different measurement preferences.

Additionally, a specialized 2½” diameter handwheel is designed for the Z-axis of the mill or vertical milling column, featuring a ball thrust bearing set to alleviate stress from the vertical lifting action. This component is standard on newer machines, while older models can be retrofitted with this upgrade. The engraved numbers on the collars are oriented for optimal readability depending on the axis of installation, ensuring ease of use across different machine configurations.
