The main parts of a wood lathe are the headstock (which holds the powered spindle), the tailstock (which supports the other end of the work), the bed that joins them, and the banjo and tool rest that support your turning tools. Around those sit the motor, the speed controls and accessories such as centers, faceplates and chucks.
Knowing each part's job makes it easier to set up safely, read a spec sheet and talk to other turners. This guide follows the labeled lathe drawing in the American Association of Woodturners (AAW) Safety Guidebook for Woodturners and the feature lists in current manufacturer manuals.

Before you switch on (AAW safety habits)
- Wear a full face shield whenever the lathe is on. Safety glasses or goggles with side protection are the minimum, and only for small items.
- Use sound wood: no cracks, splits, checks or ring shake.
- Keep the tool rest close to the work, switch off before moving the rest or banjo, and rotate the work by hand after every adjustment.
- Remove chuck keys, wrenches and knockout bars before every start.
- Start at a low speed. If you are wondering whether the speed is too high, it probably is.
- Step out of the firing line, the zone in line with the spinning work, when you switch on.
- Tie back long hair; no gloves, loose sleeves or jewelry.
- Remove the tool rest before sanding or finishing.

The headstock
The headstock is the powered end, on the left as you face the lathe. It holds the spindle in bearings and, on most lathes, the belt and pulleys that connect it to the motor.
Spindle nose thread
The spindle's threaded nose is where faceplates and chucks screw on. The AAW lists the common threads as 1 in. x 8 TPI, 1-1/4 in. x 8 TPI and M33 x 3.5. Most midi lathes use 1 in. x 8 TPI; most full-size lathes use 1-1/4 in. x 8 TPI. This is the first spec to check before you buy a chuck. See our wood lathe chuck guide for insert systems.
Morse taper
Inside the spindle is a tapered socket, the Morse taper, which holds drive centers by friction. The AAW notes that the #2 Morse taper (MT2) is the most common on woodturning lathes. Some smaller lathes use MT1, so check before ordering centers or a pen mandrel. Clean the taper before inserting anything; the AAW's alignment tips say to remove burrs from male tapers and keep female tapers clean.
Spindle bore
Many lathes have a hollow spindle. The bore lets you push a knockout bar through to eject centers and, on some lathes, run a vacuum chuck. Powermatic, for example, lists a 5/8-inch spindle bore on its 3520C and a 3/8-inch bore on its PM2014B benchtop lathe.
Handwheel
The handwheel on the outboard end lets you turn the work by hand. That is how you check clearance before every start. The AAW's guidebook says a handwheel "simplifies" spinning the work by hand before you switch on.
Indexing and spindle lock
An indexing system locks the spindle at evenly spaced positions, for fluting, layout or carving. Lathes list the number of positions: 24 is common on midi lathes, and larger machines offer more (Powermatic lists 48 on the 3520C). A spindle lock holds the spindle still while you loosen a chuck or faceplate.
Sliding or rotating headstock
On some lathes the headstock slides along the bed or rotates, so you can turn larger bowls outboard or at the end of the bed. Powermatic's 3520C and PM2014B both have sliding headstocks.
Motor, drive and speed control
Drive types
The AAW's lathe-buying guide describes three variable-speed systems:
- Reeves drive: two variable V-pulleys and a belt. The AAW says it typically will not go below about 400 RPM and must be running to adjust.
- DC variable speed: a DC motor and a dial controller. Common on midi lathes.
- AC inverter (VFD): a three-phase motor run through an inverter. It covers a wide range with strong torque but costs more.
Many midi lathes combine a variable-speed motor with two or three belt ranges, so you move the belt for big changes and use the dial for fine control.
Control box and switches
Speed dial, on/off switch and forward/reverse switch usually sit on the headstock or in a separate box. On many current lathes the box has a magnetic back so you can place it where you can reach it quickly, ideally out of the line of fire. A digital readout shows the actual RPM.
Reverse
Reverse helps when sanding. The AAW warns that a chuck or faceplate can unscrew in reverse unless it is locked with spindle set screws, and says to start reverse at slow speeds.
The bed (ways)
The bed connects the headstock and tailstock. The tailstock and banjo slide along it and clamp to it. Its length sets the maximum distance between centers, and its height above the spindle sets the swing over the bed. Many lathes accept bed extensions, which the AAW notes are inexpensive compared with buying a lathe with a long one-piece bed.
Keep the ways clean and free of rust and debris; the AAW says binding surfaces are a safety problem as well as an annoyance.
The banjo and tool rest
Banjo (tool rest base)
The banjo clamps to the bed with a lever and can slide along and across it. Its clamp should lock firmly and release easily. Some manufacturers use pinch-style or cam clamps that do not mark the bed.
Tool rest
The tool rest post drops into the banjo and locks with its own handle. The top edge of the rest supports your tool. Rests come in different lengths and shapes, from short straight rests for small spindles to curved bowl rests. Common post diameters include 5/8 inch on small lathes and 1 inch on many midi and full-size lathes, so check yours before buying a replacement. Our wood lathe accessories guide covers aftermarket rests.
The AAW's tool rest rules: keep it close to the work, always turn the lathe off before moving the rest or banjo, rotate the work by hand after each adjustment, and remove the rest before sanding or finishing.
The tailstock
Tailstock body and lock
The tailstock slides along the bed and locks with a lever. It supports the free end of spindle work and, during bowl roughing, can push a live center into the blank for extra security.
Quill (ram) and handwheel
The quill slides in and out of the tailstock when you turn the tailstock handwheel. It holds a live center, drill chuck or pen mandrel support in its own Morse taper. Many quills are hollow and self-ejecting, so winding the quill all the way back pops the center out. The AAW's checklist says not to extend the quill too far and to lock it before turning.
Quill lock
A small lever or knob locks the quill so it cannot creep back under pressure.
Live center
The live center has bearings, so its point spins with the work. Most come with interchangeable points or cones; some are hollow so you can drill through them. The AAW's alignment tips note that cheap live centers and worn bearings are a common cause of out-of-round work.
Work-holding accessories
These mount on the headstock spindle:
- Spur or drive center: grips the end of a spindle blank. Fits the Morse taper.
- Faceplate: a threaded steel or cast iron disk you screw the work to. The AAW recommends #10 or #12 sheet metal screws at minimum.
- Four-jaw scroll chuck: grips a tenon or recess on bowls and boxes.
- Pen mandrel: holds pen blanks on bushings, supported by the tailstock.
Specs that describe a lathe

| Distance between centers | Maximum spindle length |
| Motor HP and voltage | Power and the circuit you need |
| Speed range | The low end matters most for unbalanced blanks |
| Spindle thread | Which chucks and faceplates fit |
| Morse taper | Which centers and drill chucks fit |
| Weight | Mass that dampens vibration |

Lathe height and setup
The AAW's rule of thumb is that the spindle should be around the height of your heart and no lower than your elbow when you stand relaxed. Benchtop lathes need a rigid stand or bench to reach that height. Mount the lathe firmly and keep the area around it clear; the AAW recommends good overhead light plus a movable lamp aimed at the work.
FAQ
What are the main parts of a wood lathe?
The headstock (with the motor-driven spindle), the tailstock (with a sliding quill that holds a live center), the bed or ways that connect them, the banjo (tool rest base) and tool rest, and the speed and power controls. The AAW's lathe diagram also labels the legs or stand, tailstock handwheel, quill lock and internal Morse taper.
What is the banjo on a wood lathe?
The banjo is the tool rest base. It slides along the bed and clamps in place, and the tool rest post locks into it. You move the banjo and rest to keep the rest close to the work, always with the lathe switched off, per the AAW.
What is a Morse taper on a lathe?
A Morse taper is a standardized cone-shaped socket in the headstock spindle and tailstock quill that holds centers, drill chucks and mandrels by friction. The AAW notes that the #2 Morse taper (MT2) is the most common on woodturning lathes.
What is the difference between a live center and a dead center?
A live center has bearings, so its point spins with the work. A dead center is a fixed point that the work rubs against. Live centers are standard in the tailstock of modern wood lathes because they do not burn or need lubrication.
