* **Woodturning Chucks:** Chucks provide a secure and versatile way to hold the workpiece. There are various types of chucks, including jaw chucks, scroll chucks, and collet chucks.
* **Faceplates:** Faceplates are metal discs that are screwed onto the headstock spindle. They are used for mounting larger, flatter pieces of wood.

## Preparing Your Wood for Turning

Proper preparation is crucial for a successful woodturning project.

1. **Select the Right Wood:** Choose wood that is appropriate for your project. Consider the wood’s grain, density, and moisture content. Kiln-dried wood is generally preferred for turning because it is less likely to warp or crack.
2. **Cut the Wood to Size:** Cut the wood slightly larger than the finished dimensions of your project. This allows for some waste and ensures you have enough material to work with.
3. **Find the Center:** Accurately finding the center of the wood is essential for balanced turning. Use a center finder or a compass to mark the center on both ends of the wood.
4. **Mount the Wood:** There are several ways to mount wood on the lathe, depending on the project. The most common methods are:
* **Between Centers:** This method is used for turning spindles and other long, narrow pieces. The wood is held between the headstock and tailstock centers using a spur center and a live center.
* **Chuck Mounting:** This method is used for turning bowls, platters, and other hollow forms. The wood is held in a chuck that is attached to the headstock spindle.
* **Faceplate Mounting:** This method is used for turning large, flat pieces of wood. The wood is screwed directly onto a faceplate that is attached to the headstock spindle.
