What is a Lathe? How a Wood Lathe Can Transform Your Woodwork Skills

What is a lathe? It is a versatile power tool for shaping wood or metal pieces. With a wood lathe, the woodworking machine holds the wooden piece in place, turning at an incredible speed around an axis. The woodworker or wood-turner then uses special gouges, chisels, and scrapers to shape the wood. In addition to shaping wood and metal pieces, lathes are often used for finishing and polishing wooden furniture parts.

Many joiners, carpenters, and woodworking hobbyists view lathes as a crucial tool in a workshop. Only by using a wood lathe it is possible to shape wood into decorative, functional items by spinning it. However, you can also use a lathe to sand, drill, cut, and manipulate wood into various shapes.

Typical uses of a Lathe Include:

• making decorative table legs
• bed posts
• lamps
• furniture parts
• candlesticks
• chess pieces
• baseball bats
• wheels.

This article is a comprehensive guide to working with a lathe in the workshop. In addition to helpful tips for getting started using a lathe, you will find useful information on what you can use a wood lathe for.

What Is a Lathe?

A wood lathe is a workshop machine tool used to create symmetrical shapes from wooden pieces. The woodworking lathe holds the piece of wood horizontally at each end. The lathe spins the item at speeds up to 1,400 revolutions per minute. Then the woodworker can use special tools or sandpaper to achieve the desired results.

In a woodworking workshop,  a typical lathe is a large, heavy-duty machine tool that usually stands on the floor. However, if space is limited in your home workshop, you could invest in a mini lathe or bench lathe. This wood-turning tool is usually fixed to a workbench, and it is ideal if you want to turn wood but don’t have much space.

What Is the Main Purpose of a Wood Lathe?

A lathe is used for removing unwanted parts of wooden objects to create cylindrical, spherical, or otherwise round objects. The components of the lathe are designed to rotate a piece of wood. The raw material is held between the spindle and drive center and revolves at the required speed.  

What Does a Lathe Do?

Woodworkers use lathes to create shaped wooden objects that would otherwise be impossible. The lathe creates speeds of between 200 and 1,400 RPM, spinning the wood item on its axis. This piece of wood is typically held lengthwise, and the user removes unwanted parts of wood to create the desired shape.

What Are the Basic Parts of Lathe?

A wood lathe has four essential parts — the headstock, tailstock, tool rest, and the bed. Other essential elements of the lathe include the spindles to hold the wood, a motor to provide the power, and handwheels to make adjustments. Some lathes have additional accessories like lights, faceplates, and a knockout bar.

What do all the essential parts of a lathe do?

Headstock of a Lathe

The headstock is the powerhouse of the lathe. At this end of the lathe, you will find the lathe motor, drive belt, and tension pulleys. Depending on the type of lathe, the headstock may be adjustable. For example, some can turn 360°, and others can move in a lateral direction along the length of the lathe.

Essential lathe parts of the headstock include the handwheel, drive belt, and spindle.

Wood Lathe Spindle

The headstock spindle and tailstock spindle are the two essential parts of a lathe that hold the wood in place. Pulleys and belts drive the headstock spindle. You’ll notice that this spindle has an external thread to accept various attachments. Two critical measurements to know are the spinning thread diameter and the thread count.

Bed of the Lathe

The bed is the base part of the structure upon which all the lathe parts are mounted. Typically, the bed consists of two flat horizontal rails. These allow the tailstock and tool rest to move in a longitudinal direction, depending on the length of the wooden item being turned.

The lathe’s swing is an essential specification regarding the headstock, spindle, and bed. This measurement is the distance from the spindle to the bed. For example, if the spindle is 6” above the bed, the lathe swing is 12”. Therefore, you can turn a bowl up to 12” in diameter.

Tool rest

As its name suggests, the lathe tool rest is designed for the woodworker to hold shaping tools and chisels steady and shape in a straight line.

The tool rest consists of a flat metal horizontal top edge connected to the lathe bed. The tool rest is adjustable and can be turned, raised, angled, or lowered using the lathe banjo to hold it in place.

How should you position the tool rest?

Ideally, you should place the tool rest as close to the turning wood as possible without touching it. This gives you better control over the shape of the wooden item you are turning. It also helps you identify high or low spots on the wood.

Wood Lathe Tailstock

The tailstock is the part of the lathe at the opposite end of the headstock. This part is movable and adjustable to suit the length of the wooden item. It is also removable if you are making wooden bowls. The tailstock consists of the spindle, locking mechanism, and the tailstock handwheel.

Typically, the tailstock has a hollow Morse Taper hole so that you can attach accessories, like a live center, taper, or chuck adapter.

You will also notice that the tailstock has a hand wheel. This is a precision threaded screw drive used to move the tailstock spindle closer or further away from the wooden item.

Additional Wood lathe accessories

Several accessories for working with a lathe can help you do intricate work. For example, chucks, catch plates, face plates, and mandrels are just some accessories for a lathe you can attach to the spindle. You can use these to hold the workpiece in place and create threads, chamfers, knurls, and much more.

Here are brief explanations of how you can use accessories on the lathe.

• Centers: Centers are the most common lathe accessories and are used to hold different types of workpieces in place at either end.
• Chucks: The lathe chuck is used to clamp the workpiece to the lathe securely. This is mounted on the headstock and can be used with or without attaching the workpiece to the tailstock.
• Faceplate: If you are turning wooden bowls, then a faceplate is an essential lathe accessory. You attached the faceplate to the wooden item using wood screws.
• Mandrels: Using a mandrel on a wood lathe is essential if you want to turn cylindrical, hollow wood workpieces.

What Operations Can Be Done on Wood Lathe?

Turning, facing, and boring are the three most common types of operations you can use a lathe for. However, the wide range of lathe tools and accessories means it’s a versatile workshop tool capable of carrying out different operations to create stunning wooden objects.

Here are six operations that can be done on a lathe

1. Turning

Turning describes the lathe process of removing materials from the outer surface of a rotating work piece. This reduces the work-piece diameter to its required dimensions. There are various shapes you can achieve by turning wooden items. These include the following:

• Step turning: This lathe operation creates an abrupt diameter change that resembles a step.
• Taper turning: You can use the turning tool to create a gradual transition between the two surfaces using an angled transition. This is sometimes called a ramp transition.
• Contour turning: Cutting tools are used to create curved and contoured three-dimensional shapes on a work-piece.
• Chamfer turning: This is similar to the step turning process but creates a small, angled transition between two surfaces.

2. Facing

Facing is a type of turning operation on a lathe that refers to removing a thin layer of material from the end of a work-piece to achieve its desired length.

3. Boring

As the name suggests, boring a work piece on a lathe means removing material from the internal part of the item. You can use boring to create a hole or enlarge an existing hole.

4. Grooving

Grooving is a type of turning operation that makes a groove in the work piece. Depending on the groove size, you may need to make several passes to achieve the desired width.

5. Threading

You can use a lathe to create threads on the other surface of the work piece. To do this, you would use a special turning tool that makes threads at the correct width and pitch.

6. Knurling

You can knurl wood on a lathe to add decorative angled, straight, or crossed lines to the surface of a work-piece. The knurling tool is a small wheel with a pattern cut on it. Typically, knurling wood is only suitable for high-density, hard woods. You can also use a checkering process to create a knurling effect.

How Do You Cut on a Lathe?

The cutting process on a wood lathe is typically relatively straightforward. First, the lathe rotates the work-piece around its axis.

Then, to cut on the lathe, you use a cutting tool to remove thin layers of material by moving the tool parallel to the main cutting axis. This way, you can cut the wooden item into a cylindrical shape.

The type of cutting you can perform on a lathe depends on the cutting tool and how you move it.

For example, you can cut ornate three-dimensional curved shapes, make threads in wooden cylinders, machine tapered ends on wooden poles, or create grooves.

What Wood Is Best for a Lathe?

The best varieties of hardwood for use in a lathe are maple, walnut, and cherry. These wood types are relatively easy to work with and have attractive grains. However, because these woods are dense and hard, you’ll need to keep tools sharp and use a higher lathe speed than for softwoods like pine or cypress.

Here is a list of the ten best types of wood for a lathe and how to use them.

• Maple: This is easy to work with and has an attractive closed grain. Ideal for turning bowls.
• Walnut: Another easy hardwood for a lathe that can produce an excellent finish with relative ease.
• Cherry: This is one of the most popular woods for turning in a lathe and makes attractive bowls.
• Birch: This easy-to-work-with wood is popular because it’s dense, hard wearing, and creates a nice finish. However, turned items can be somewhat bland because of a lack of grain.
• Rosewood: This type of compact wood is naturally beautiful, and it doesn’t take much work to get a great finish.
• Hickory: If you are creating heavy-duty items, then hickory is the “go-to” choice of carpenters. It has an attractive grain and is relatively easy to handle.
• Boxelder: This hardwood has medium difficulty when turning it on a wood lathe. However, it’s worth the effort because it is easy to sand and creates a stunning finish.
• Poplar: If you are new to using a wood lathe, then poplar is an excellent wood to start with. Because it is relatively soft, it’s easy to work with.
• Cypress: This softwood is easy to turn on a wood lathe and is better than pine.
• Olive tree: Although it is one of the toughest woods to turn on a lathe, olive wood has impressive textures and finishes. Always turn olive tree wood using the sharpest tools and spinning at high speeds.

What Is the Easiest Wood to Turn on a Lathe?

Without a doubt, the easiest wood for turning on a lathe is maple and cherry. The beauty of these woods is that they don’t tear out quickly because of their density. In addition, you can achieve fantastic finishes with relative ease. They are the wood of choice for turning out bowls.

What’s the easiest wood to turn if you’re a beginner?

In that case, try a softwood from a coniferous variety of trees. Many woodworker newbies go for pine because it’s cheap and available. However, other suitable softwoods for beginners are beach, poplar, elm, and cypress.

Is Using a Lathe Hard?

Learning the basic techniques for turning wood isn’t hard. You can start with the four types of essential cutting tools to create fillets, coves, square cuts, and V-shaped grooves. Then you only need to practice on different types of wood. After learning the wood turning basics, you will start producing excellent and attractive pieces of carved or turned wood

How Long Should Wood Dry Before Turning?

Generally, wood takes one year of drying per inch of thickness before it is ready for turning in a lathe machine. However, you can speed up the process by drying wood in a kiln. Alternatively, you can purchase pre-dried wood. Working with dry wood prevents the wood from warping, cracking, or splitting.

There is another reason why using green wood isn’t a great idea. Because the wood is “wet,” your tools will easily get clogged, and it will take more time to turn wood. It is also common that a turned bowl made from green wood eventually cracks as it dries out naturally.

What Is a Lathe-Conclusion

A wood lathe is an essential machining tool if you want to create ornate three-dimensional spherical or cylindrical objects from timber. After learning the basics of how to use a lathe, it’s easy to develop your skills to become an expert wood turner. In no time, you will start turning out decorative bowls, table legs, handles, candlesticks, chess pieces, and even baseball bats.
