Pneumatic Bar Feeder Activation Cylinder Assembly
We’ve separated the Bar Feeder into two components to better support customers who want to build their own custom bar feeder system.
Beyond its use in a bar feeder setup, this assembly can also function as a programmable collet control for opening and closing the collet. You can use M10 and M11 G-code commands to close and open the chuck, respectively.
The Pneumatic Bar Feeder Activation Cylinder Assembly works with our machine and 3C lever collet closer to pneumatically open and close the collet. Click the “Instructions” tab above to download setup documentation.
NOTE: This system is designed for use with the MASSO Touch controller featuring the G3 board. The older G2 board is not compatible with the required MASSO relay module. If you are using a control system other than the MASSO Touch, please consult your controller manufacturer for wiring diagrams and compatibility. Most modern CNC controllers are designed to send relay signals to control external devices.

Knurling Tool Holder
Sherline's knurling tool adds a professional touch to your parts by embossing knurls into the surface, rather than cutting them. Straight knurls are commonly used on the ends of shafts that will be pressed into other parts, while both straight and diamond knurl patterns are ideal for enhancing grip on handwheels and thumbscrews.
This tool can accommodate diameters up to 1" (25 mm) and features both right and left sides that evenly clamp down on your part as it's turned in the lathe, creating a consistent knurled pattern. It comes with one set of spiral knurls that form a diamond pattern.
Additional sizes of knurls for both diamond and straight patterns are also available in the addition knurls tab below.
Note: This knurling tool is not intended for use with riser blocks.

1/4″ Drill Chuck with #1 Morse Arbor
The Sherline Milling Machine makes an excellent precision drilling machine. Accurate positioning of both the "X" and "Y" axes provide a simple way to locate holes, and, although the Sherline does not have a quill feed, the "Z" axis feed screw does give you micrometer accuracy for depth control. The drill chuck is similar to the tailstock chuck used with the lathe in that it is a 3/32" (2.4 mm) to 1/4" (6.35 mm) drill chuck mounted on a #1 morse arbor. The difference is that this arbor has been drilled and tapped for a drawbar. The drawbar prevents the arbor from working loose during use.
NOTE: If runout of less than .003″ amount is required, collets should be used to hold the drill rather than a chuck. This chuck is NOT designed for lateral loads and should not be used for holding end mill cutters
1/4″ Drill Chuck with 2 Arbors
A drill chuck is probably the most important accessory you will need for your lathe. It will enable you to accurately centerline drill, ream, or tap any part mounted on the lathe. The part to be machined is chuck or collet mounted in the headstock. The tool is mounted in the tailstock chuck and fed into the part using the tailstock ram feed. Parts that are going to be mounted between centers can be center drilled this way. Other parts requiring a hole accurately drilled on-center can also be machined this way.
The Sherline tailstock chuck is a precision 3/32" (2.4 mm) to 1/4" (6.4 mm) 3-jaw chuck complete with key. The chuck is fitted with a #0 Morse arbor for use in the tailstock. Also included is a #1 Morse arbor and drawbolt so the chuck can be used in the lathe or mill headstock as well.
NOTE: If runout of less than .003″ amount is required, collets should be used to hold the drill rather than a chuck.
Thread-Cutting Attachment
A key advantage of owning a lathe is the ability to machine threads. While taps and dies can cut many threads, acquiring a comprehensive tap and die set to cover all non-standard thread sizes can be costly. Sherline provides a unique and versatile thread-cutting attachment for its lathe. This affordable attachment enables you to machine thirty-six different unified thread pitches (ranging from 80 to 5 threads per inch) and twenty-eight different metric thread pitches (ranging from .25 to 2.0 mm). It also allows for both left-hand and right-hand threading. A 60° carbide cutting tool is included, but you can also grind a standard high-speed steel tool to cut various thread forms at any pitch diameter. This versatility allows you to machine both standard and non-standard inside or outside threads, as long as they fall within the lathe’s size limitations.
Note: Ensure you lubricate the gears with light oil before using the threading attachment.
The attachment includes:
Thread cutting on the Sherline lathe is accomplished by gearing the spindle to the leadscrew. As the spindle is rotated using the handwheel mounted on the headstock spindle, the tool advances according to the gear ratio. Once the tool reaches the end of its movement, simply stop cranking, reverse the tool, and turn the spindle in the opposite direction until the tool passes its starting point. Reset the tool, and you’re ready for the next pass. It’s as straightforward as tapping! By using the supplied 127-tooth gear, you can cut true metric threads on an inch lathe or true inch threads on a metric lathe.
⚠️ Note: The thread-cutting attachment is not compatible with the 3C Headstock.
Adapting the Leadscrew Engagement Lever for Use with Digital Readout (DRO)
If you plan to use the leadscrew engagement lever with the Thread Cutting Attachment in conjunction with a Digital Readout (DRO), you will need to equip your lathe with the DRO sliding shaft (sold separately) for proper leadscrew engagement.Gear Selection Calculator
The Sherline Thread Attachment Calculator, created by Joo Beng Koh of Singapore, automates gear selection based on your desired thread count. Originally shared on the Sherline Lathe & Mill Facebook Group, Joo Beng graciously allowed us to feature this tool on our website. The calculator simplifies the setup process, particularly for users who frequently change their thread specifications.
For instructions, select the desired parameters in the light yellow fields, and the corresponding gear selections will appear in the green boxes. An accompanying image shows the correct gear placement along with step-by-step guidance for installation. This tool has greatly improved the process for Joo Beng and can help others as well.

2.5″ 3-Jaw Chuck – Electroless Nickel Coated
This chuck is identical to P/N 1041 except for an electroless Nickel coating that has been applied to help prevent wear and corrosion. This special coating has been applied to all external and internal surfaces of the chuck (except for chuck jaws), significantly improving the life of the chuck. This chuck also opens and closes more smoothly due to the lubrication properties of Nickel-Teflon.
Some of our customers have been wondering how to tell the difference between our standard chucks and those that have the electroless Nickel coating. Standard chucks have darker markings than the coated chucks (See Figure 1. Click on photo to view a larger image).

Figure 1—Examples: (Left) 1040 3-Jaw Chuck (3.1″), (Right) 1040C Electroless Nickel Coated 3-Jaw Chuck (3.1″).[/caption]
Here, at Sherline Products, each of our chucks is laser engraved with a company mark, chuck size, and jaw location. During the laser marking process the laser removes a bit of the surface and darkens the material below (Figure 1, left). When chucks are sent out to receive the Nickel finish the coating process changes the dark engraved markings to a noticeably lighter finish (Figure 1, right).
There is also a subtle change in the color of the chuck, but in the absence of being able to compare them side by side, the most evident way to tell whether you have a coated chuck, or not, is to check the color of the laser markings.
3.1″ 3-Jaw Chuck
This larger chuck takes up no more center-to-center space than the 2.5" chuck, but it will hold larger work. It has a clamping range of 3/32" (2 mm) up to 1-1/2" (38 mm) diameter with the jaws in the normal position. With the jaws in the reversed position, work up to 3-1/4" (82.5mm) can be gripped. The hole through the chuck is .687" (17 mm). Rotating the knurled ring closes all three jaws simultaneously to grip round or hexagonal stock quickly. Tommy bars (provided) are used in the side holes to tighten and loosen the chuck for more leverage. The chuck has a 3/4-16 thread to fit Sherline's spindle.

2.5″ 4-Jaw Chucks – Various Thread
Includes 2 tommy bars, not pictured
This chuck combines the ease-of-use advantages of the 3-jaw chuck with some of the advantages of a 4-jaw chuck. It will automatically center square or round stock. (The stock must be accurately shaped for all four jaws to grip.) It will also grip thin-wall tubing in four places rather than three, which spreads out the load and allows more grip without crushing the tubing.
Turning the knurled portion of the outer diameter of the chuck scrolls all four jaws in unison. Included with the chuck are two Tommy bars for tightening and loosening the chuck.
Centering accuracy on self-centering chucks is to within a few thousandths of an inch. If perfect centering accuracy is required, see the section on 4-jaw independent jaw chucks.
This chuck will hold parts from 3/32" in diameter up to 1-3/16" with jaws in the normal position and up to 2-1/4" with the jaws reversed.
Chucks for Sherline and Other LathesThe chuck is available in several spindle threads for use on Sherline (3/4-16) and other machines such as old Unimat lathes (12mm x 1mm and 14mm x 1mm). *Please note that chucks with a thread size other than 3/4" x 16 are made to order and have a lead time of 5-7 business days.

3/8″ Drill Chuck with #1 Morse Arbor
This chuck includes a #1 Morse arbor and drawbolt so that it can be mounted in the headstock of the lathe or mill. It will hold drills from 3/32" (2.4 mm) to 3/8" (9.5 mm) in diameter. If runout of less than .003″ amount is required, collets should be used to hold the drill rather than a chuck.
NOTE: Because of its longer length and ability to hold longer 3/8" drills, this chuck is normally recommended for use on the longer 4400-series benchtop lathes.
