= Woodturning Safety

- Use a full face shield (Safety glasses at a minimum) whenever the lathe is turned on.
- Tie back long hair, do not wear gloves, and avoid loose clothing or objects that may catch on rotating parts or accessories.
- Always check the speed of the lathe before turning it on. Use slower speeds for larger diameter or rough pieces, and higher speeds for smaller diameter and pieces that are balanced. Always start a piece at a slower speed until the work piece is balanced. If the lathe is shaking or vibrating, lower the speed. If the work piece vibrates, always stop the machine to check the reason.
- Check that all locking devices on the tailstock and tool rest assembly (rest and base) are tight before operating the lathe.
- Position the tool rest close to work, about one inch away from the material. Check tool rest position often and as wood is removed, turn off the lathe and re-position the rest.
- Rotate your work piece by hand to make sure it clears the tool rest and bed before turning the lathe's motor on. Be certain that the work piece turns freely and is firmly mounted. A handwheel on the outboard side of the headstock simplifies this process of spinning the lathe by hand before turning on the switch.
- Be aware of what the turners call the _red zone_ or _firing zone._ This is the area directly behind and in front of the work piece - the areas most likely for a piece to travel as it comes off the lathe. A good safety habit is to step out of this zone when turning on the lathe. When observing others turn stay out of the area.
- Hold turning tools securely on the tool rest, holding the tool in a controlled and comfortable manner. Always contact the tool rest with the tool before contacting the wood.
- Turn the lathe off before adjusting the tool rest or tool rest base (banjo). 
- Remove the tool rest before sanding or polishing operations.
- Never leave the lathe running unattended. Turn the power off. Do not leave the lathe until it comes to a complete stop.

= Introduction

== Learning Objectives


== Woodturning Terminology

When you read about woodturning or talk with woodturners, these are some terms you're likely to encounter.

/ Bevel: The area beneath the cutting edge of a scraper or gouge. The bevel on a gouge is always held in contact with the wood.

/ Blank: A piece of wood rounded smooth or cut into a section for lathe use.

/ Burl: An unusual growth on a tree, producing swirls and other interesting grain patterns.

/ Heartwood: The fully developed wood surrounding the core, usually darker than sapwood (see below) and really dense.

/ Moisture content: Percentage of water weight to total weight. Moisture content is usually 30 to 40 percent or more when wood is freshly cut (aka "green"). Dry wood typically has moisture content of less than seven to eight percent.

/ Sapwood: This surrounds heartwood and is usually softer. It transports sap from roots to leaves. It's a different color than the heartwood. 

/ Spalted wood: Wood in the process of fungal decay that shows as black lines in the grain. Woodturners prize spalted wood because the black lines add an artistic element to the turning.
