- If you already have a Sherline Linux PC or 4-axis driver box, configure the controller
with:
- Spindle Control Isolator Board
- External Encoder kit for your headstock (Standard or 3C)
- Wants a complete Sherline system: CNC-ready machine, 24 V stepper motors, 4-axis driver box, spindle control isolator board, and external encoder.
- The Sherline/Acorn Controller is designed to support all of these configurations.
- To control spindle speed via G-code, you must have a motor drive or the Spindle Control Isolator Board and an external encoder installed.
- These components work together to accurately acquire and control spindle RPM.
- If you do not include the Spindle Control Isolator Board at the time of purchase, adding it later will require returning the controller to Sherline for installation. Email orders@sherline.com for return instructions.

Jeweler Point Carver System
Our Jeweler Point Carver System was developed in response to a request from Everett Walker Jewels. You can view Everett’s exceptional craftsmanship on Instagram at @everettwalkerjewels
Designed primarily for lapidary applications, this system provides jewelers with a precise and secure method for carving, shaping, and detailing stones and other small components.
The system is built around our P/N 3306 headstock, which features a Morse #1 spindle taper. It can be purchased as a complete, standalone system or the point carver holders can be purchased as an accessory for any Sherline lathe equipped with a Morse #1 headstock.
At the core of the system is the headstock, paired with a motor and electronic speed control to deliver smooth, variable-speed operation.
The system offers four interchangeable holder options. Each holder features a Morse #1 taper mount that fits directly into the headstock spindle. The taper mount provides a highly secure and concentric connection, making it one of the most reliable methods for mounting accessories on a rotating axis.
Each holder includes our P/N 30880 ¼-20 drawbolt and washer, ensuring the holder is securely retained within the spindle’s Morse #1 taper during operation.
The Point Carver System also includes our P/N 1156 #1 Morse Taper Remover, allowing holders to be safely and easily released from the spindle taper when changing setups.

13″ Lathe Crosslide Assembly – DRO
13″ Lathe Crosslide Assembly – Manual
This 13" crosslide is designed for users who want to convert their Sherline lathe into a Chucker Lathe or gang-tooling lathe. Its extended length allows for mounting multiple gang-tooling tool posts along the crosslide.
The 13" crosslide measures .870" thick, compared to .625" for the standard 6" crosslide. Due to its increased thickness, this crosslide is not recommended as a direct replacement for standard lathe use. To bring the tooling on center with the headstock, a Headstock Riser Plate is required.
When using this setup, note that:
The 13" crosslide includes a leadscrew and a standard 1-5/8" handwheel, saddle not included.
Indexing Attachment
Machining operations often require cutting features in a radial pattern rather than in a straight line. Common examples include gear teeth, splines, and flats on nuts. The Sherline Indexing Attachment provides an economical and highly accurate way to rotate and position a workpiece for machining these types of features.
Features & Benefits
Included Components
Spindle Compatibility
The indexing head uses a spindle with a #1 Morse taper and 3/4"-16 male thread, identical to Sherline lathe and mill spindles. This allows the use of common Sherline accessories, including:
Precision Indexing Capability
For positions beyond the standard 5° detents, the rack gear converts spindle rotation into measurable linear travel. This movement can be measured with the depth rod of a Vernier caliper, allowing extremely accurate indexing to an infinite number of positions.
Mounting & Use
The indexing attachment can be mounted directly to the table of a Sherline milling machine. The indexing head may also be used independently in a horizontal position similar to a rotary table.
Note: Use on a Sherline lathe with the vertical milling column is not recommended. However, it may be possible with shims installed to raise the unit high enough to clear the crosslide handwheel.
18″ Extended Mill Table
By popular demand, particularly in the CNC market, Sherline now offers an extended mill table that is 18″ long, extending the X-axis travel to 12.38″. It is the same width and thickness as the standard 13″ table and the T-slots … Continued
