SAFETY

For Machines Mfd. Since 10/23

Additional Wood Lathe Safety

Serious injury or death can occur from getting entangled in, crushed between, or struck by rotating parts on a lathe! Rotating workpieces can come loose and strike operator or bystanders with deadly force if they are improperly secured, rotated too fast, or are not strong enough for the rotational forces required for turning. Improper tool setup or usage can cause tool kickback or grabbing, resulting in impact injury or entanglement. To reduce the risk of operator (or bystander) injury or death, anyone operating this machine MUST completely heed the hazards and warnings below.

Verify Workpiece Integrity. Verify each workpiece

is free of knots, splits, nails, or foreign material to ensure it can safely rotate on spindle without breaking apart or causing tool kickback.

Properly Prepare Workpiece. Before mounting,

cut off waste portions to balance workpiece for safe rotation and removal of large edges that can catch on tooling.

Secure Locks. Verify tool rest, headstock, and

tailstock are secure before turning lathe ON.

Secure Workpiece. Use proven setup techniques

and always verify workpiece (and centers/ tooling holding workpiece) are well-secured before starting lathe. Only use high-quality fasteners with non-tapered heads for faceplate attachment.

Adjust Tool Support. An improperly supported

tool may be grabbed or ejected. Adjust tool rest approximately

⁄8" above workpiece center line to

and provide proper support for turning tool. Firmly hold turning tool with both hands against tool rest.

Remove Adjustment Tools. Remove all chuck

keys, wrenches, and adjustment tools before turning lathe ON. These items can become deadly projectiles when spindle is started.

Check Clearances. Before starting spindle,

verify workpiece has adequate clearance by hand-rotating it through its entire range of motion.

Test New Setups. Test each new setup by starting

spindle rotation at lowest speed and standing to side of lathe until workpiece reaches full speed and you can verify safe rotation.

⁄4" away from workpiece

Wear Proper PPE. Always wear a face shield and

safety glasses when operating lathe. Do not wear gloves, necktie or loose clothing. Keep long hair away from rotating spindle.

Use Correct Speeds. Select correct spindle

speed for workpiece size, type, shape, and condition. Use low speeds when roughing or when turning large, long, or non-concentric workpieces. Allow spindle to reach full speed before turning.

Avoid Tool Kickback. This occurs when turning

tool is grabbed or ejected from workpiece with great force. Commonly caused by poor workpiece selection/preparation, improper tool usage, or improper machine setup or tool rest adjustment.

Safely Perform Roughing. Use correct tool.

Take light cuts, use low speeds, and firmly support tool with both hands.

Use Sharp Tools. Sharp tools cut with less

resistance than dull tools. Using dull tools increases the risk of tool kickback or grabbing.

Safely Stopping Rotation. Always allow rotating

workpiece to stop on its own. Never put hands or another object on workpiece to stop it.

Safely Measure Workpiece. Only measure

mounted workpiece after it has completely stopped. Trying to measure a spinning workpiece increases entanglement risk.

Sanding/Polishing. To reduce entanglement

risk, remove tool rest before sanding. Never completely wrap sandpaper around workpiece.

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed.

To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by a or qualified service personnel in accordance with applicable electrical codes and safety standards.

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result—especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the requirements in the following section.

This machine is prewired to operate on a power supply circuit that has a verified ground and meets the following requirements:

Note: The circuit requirements in this manual are for machine will be running at a time. If this machine will be connected to a shared circuit where multiple machines will be running at the same time, consult a qualified electrician to ensure the circuit is properly sized.

A power supply circuit includes all electrical equipment between the main breaker box or fuse panel in your building and the incoming power connections inside the machine. This circuit must be safely sized to handle the full-load current that may be drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)

and a respirator when operating this machine.

To complete a typical operation, the operator does the following:

1. Examines workpiece to make sure it is

suitable for turning. No extreme bows, knots, or cracks should exist.

Prepares and trims up workpiece with a

bandsaw or table saw to make it roughly concentric.

Installs workpiece between centers, or

attaches it to faceplate or chuck.

Adjusts tool rest according to type of

operation, and sets minimum clearance between workpiece and lip of tool rest to ¼"gap.

Rotates workpiece by hand to verify spindle

and workpiece rotate freely throughout full range of motion.

Veriﬁes pulley speed range is set for type of

wood and size of workpiece installed.

Veriﬁes spindle speed dial is turned all the

way counterclockwise so spindle does not start in high speed.

OPERATION

Stock Inspection & Requirements

Some workpieces are not safe to turn or may require modiﬁcation before they are safe to turn. Before turning, inspect all workpieces for the following:

• Workpiece Type:

This machine is intended for turning natural

wood products. Never attempt to turn any composite wood materials, plastics, metal, stone, or rubber workpieces; turning these materials can lead to machine damage or severe injury.

• Foreign Objects:

Nails, staples, dirt, rocks and other foreign

objects are often embedded in wood. While cutting, these objects can become dislodged and hit the operator, cause tool grab, or break the turning tool, which might then ﬂy apart. Always visually inspect your workpiece for these items. If they can't be removed, DO NOT turn the workpiece.

Adjusting Tailstock

The Model SB1126 tailstock is equipped with a cam-action clamping system to secure it to the lathe bed. When the lever is tightened, a clamping plate lifts up underneath the bed and secures the tailstock in place. The tailstock can be positioned anywhere along the lathe bed.

If clamping plate is not tight enough for lock lever to fully secure tailstock base, it could unexpectedly slip during operation and workpiece could be ejected at high speed. Failure to heed this warning could result in serious personal injury.

To adjust tailstock:

1. Loosen tailstock lock lever and move

tailstock to desired position along bed, as shown in Figure 18.

• Large/Loose Knots:

Loose knots can become dislodged during the

turning operation. Large knots can cause a workpiece to completely break in half during turning and cause machine damage and injury. Choose workpieces that do not have large/loose knots.

• Excessive Warping:

Workpieces with excessive bowing or

twisting are unstable and unbalanced. Never turn these workpieces at high speed, or instability will be magniﬁed and the workpiece can be ejected from the lathe causing injury. Only turn concentric workpieces!

• Wet or "Green" Stock:

Turning wood with a moisture content over

20% can cause increased wear on tooling.

South Bend Tools

For Machines Mfd. Since 10/23 Model SB1126

OPERATION

Adjusting Tool Rest

The tool rest assembly consists of two components: the tool rest base (or banjo) and the tool rest. The tool rest base moves forward/ backward and along the length of the lathe bed. The tool rest rotates and moves up and down in the tool rest base. Locks for both components allow you to secure the tool rest in position after making these adjustments.

When adjusting the tool rest, position it as close as possible to the workpiece without actually touching it. This maximizes support where the cutting occurs and minimizes leverage, reducing the risk of injury if a "catch" occurs. Many woodturners typically set the height of the tool

⁄8" above or below the centerline of the

rest workpiece, depending on their height, the type of tool they are using, and the type of operation they are performing.

As a rule of thumb: For most (spindle) turning operations, the cutting tool should contact the workpiece slightly above centerline. For most inside (bowl) turning operations, the cutting tool should contact the workpiece slightly below centerline.

Keeping all these factors in mind, your main goal when adjusting the tool rest should be providing maximum support for the type of tool being used, in a position that is safe and comfortable for you.

To adjust tool rest:

1. Loosen tool rest base lock lever and move

tool rest assembly to desired position on lathe bed, as shown in Figure 24.

Note: To maximize support, tool rest base

should always be locked on both sides of bed. Never pull tool rest so far back that it is only secured on one side.

Tool RestTool Rest

Figure 24. Tool rest assembly components.

If clamping plate is not tight enough for lock lever to fully secure tool rest base, or lock handle is not tight enough to fully secure tool rest, they could unexpectedly slip during operation and draw turning tool and your hand into spinning workpiece. Failure to heed this warning could result in serious personal injury.

Lock HandleLock Handle

Tool Rest BaseTool Rest Base

Lock LeverLock Lever

Improperly supported or positioned cutting tools can "catch" on workpiece, ejecting tool from your hands with great force. To reduce this risk, always ensure tool rest is properly positioned for each type of operation, cutting tool is firmly supported against tool rest BEFORE cutting, and cutting tool is properly positioned to cut at the correct angle for tool and operation type.

2. Rotate tool rest base lock lever until it feels

tight to secure tool rest base on bed.

Note: Large clamping plate and hex nut

underneath tool rest base will require occasional adjusting to ensure proper clamping pressure of tool rest assembly to bed. Turn this hex nut in small increments to ﬁne tune clamping pressure as needed.

workpiece by hand to ensure there is safe clearance on all sides.

Keep lathe tool resting on tool rest the ENTIRE time it is in contact with workpiece or when preparing to make contact between lathe tool and workpiece. Otherwise, spinning workpiece could force lathe tool out of your hands or entangle your hands with workpiece. Failure to heed this warning could result in serious personal injury.

Spindle Turning Tips

• When turning the lathe ON, stand away

from the path of the spinning workpiece until the spindle reaches full speed and you can verify that the workpiece will not come loose.

• Use the slowest speed when starting or

stopping the lathe.

• Select the right speed for the size of the

workpiece that you are turning (refer to Changing Speed Range on Page 28).

• Keep the turning tool on the tool rest the

ENTIRE time that it is in contact with the workpiece.

• Learn the correct techniques for each tool

you will use. If you are unsure about how to use the lathe tools, read books or magazines about lathe techniques, and seek training from experienced and knowledgeable lathe users.

OPERATION

Faceplate Turning

To reduce risk of eye injury from flying chips or lung damage from breathing dust, always wear safety glasses, a face shield, and a respirator when operating this machine.

Faceplate turning is when a workpiece is mounted to the faceplate, which is then mounted to the headstock spindle, as shown in Figure 35. This type of turning is usually done with openfaced workpieces like bowls or plates.

For Machines Mfd. Since 10/23

Outboard Turning

To reduce risk of eye injury from flying chips or lung damage from breathing dust, always wear safety glasses, a face shield, and a respirator when operating this machine.

Outboard turning is a variation of faceplate turning and is accomplished by removing the bed extension and installing it on the outboard end of the lathe, allowing for a larger turning capacity. Another method would be to use a ﬂoor-mounted tool rest, which would provide the maximum possible amount of swing.

OPERATION

Selecting Turning Tools

Lathe tools come in a variety of shapes and sizes, and usually fall into ﬁve major categories:

Gouges

• Mainly used for rough cutting, detail cutting, and cove profiles. The rough gouge is a hollow, double-ground tool with a round nose, and the detail gouge is a hollow, double-ground tool with either a round or pointed nose.

Scrapers

• Typically used where access for other tools is limited, such as hollowing operations. This is a flat, double-ground tool that comes in a variety of profiles (round nose, spear point, square nose, etc.) to match many different contours.

Figure 43. Example of a round nose scraper.

Figure 41. Example of a gouge.

Skew Chisel

• A versatile tool that can be used for planing, squaring, V-cutting, beading, and parting off. The skew chisel is flat, double-ground with one side higher than the other (usually at an angle of 20°–40°).

Parting Tools

• Used for sizing and cutting off work. This is a flat tool with a sharp pointed nose that may be single- or double-ground.

Figure 44. Example of a parting tool.

Specialty Tools

• These are unique, special function tools to aid in hollowing, bowl making, cutting profiles, etc.

Maintenance Schedule

Always disconnect machine from power before performing maintenance or serious personal injury may result.

For optimum performance from your machine, follow this maintenance schedule and refer to any specific instructions given in this section.

To minimize your risk of injury and maintain proper machine operation, shut down the machine immediately if you ever observe any of the items below, and fix the problem before continuing operations:

Ongoing

• Loose faceplate or mounting bolts.

• Damaged center or tooling.

• Worn or damaged wires.

• Loose machine components.

• Any other unsafe condition.

Cleaning

Cleaning the Model SB1126 is relatively easy. Vacuum excess wood chips and sawdust, and wipe off the remaining dust with a dry cloth. If any resin has built up, use a resin dissolving cleaner to remove it. Treat all unpainted cast iron and steel with a non-staining lubricant after cleaning.

Unpainted Cast Iron

Protect the unpainted cast iron surfaces on the bed by wiping the bed clean after every use— this ensures moisture from wood dust does not remain on bare metal surfaces. Keep beds rustfree with regular applications of products like SLIPIT

Bare metal surfaces can quickly develop surface rust if not coated. Machinery stored near windows in direct sunlight or where paints, thinners, or certain gasses are open to the air can experience bleaching, discoloring of paint or yellowing of clear plastic guards.

(Page 36).

Daily

• Clean off dust buildup.

• Clean and lubricate lathe bed, spindle, and

quill.

Monthly

• Belt tension, damage, or wear.

• Clean out dust buildup from machine

interior.

Lubrication

Since all bearings on the Model SB1126 are sealed and permanently lubricated, simply leave them alone until they need to be replaced. DO NOT lubricate them.

Wipe a lightly oiled shop rag on the outside of the headstock spindle. DO NOT allow any oil to get on the inside mating surfaces of the spindle.

Use the tailstock handwheel to extend the quill out to the furthest position and apply a thin coat of white lithium grease to the outside of the quill. DO NOT allow any oil or grease to get on the inside mating surfaces of the quill.
