🔍 Key Concepts

• Lathe dog purpose – how it drives the work when turning between centers • Difference between a common lathe dog and a safety lathe dog in terms of operator protection • What extra mechanical feature might reduce the chance of the workpiece or dog catching on clothing or equipment

💭 Think About

• Think about which option describes a feature specifically intended to improve safety for the operator, not just accuracy or alignment • Ask yourself: Which choice adds something that could help prevent the dog from flying off or snagging during operation? • Consider how each choice would actually change the behavior of the dog while rotating with the workpiece

✅ Before You Answer

• Identify which option clearly adds a safety-related mechanism, not just a different screw or better centering • Eliminate any choices that only describe alignment or setup convenience, rather than injury prevention • Visualize how a lathe dog attaches to the faceplate or drive plate and which feature would secure or shield that connection during rotation
