What is lathe dog?

A lathe dog, also known as a lathe carrier or a lathe driver, is a mechanical device used in metalworking and woodworking to secure and drive a workpiece on a lathe machine. It is typically a metal clamp that attaches to the workpiece through slots or holes and connects to the lathe spindle to rotate the workpiece during machining operations.

Lathe dogs come in various shapes and sizes to accommodate different types of workpieces and lathe machines. They are essential tools for holding and rotating irregularly shaped or oversized workpieces that cannot be held securely by a chuck or collet.

When using a lathe dog, it is important to ensure proper alignment and secure clamping to prevent slippage or damage to the workpiece. Additionally, care should be taken to avoid over tightening the lathe dog, as this can cause deformation or distortion of the workpiece.

Overall, lathe dogs are versatile tools that provide a safe and efficient way to hold and rotate workpieces on a lathe machine, making them essential for a wide range of turning and machining operations.
