A wood lathe is specifically designed for working with wood, while a metal lathe is designed for working with metal. Wood lathes typically have lower speed ranges and higher torque to accommodate the softer and less dense nature of wood, while metal lathes have higher speed ranges and lower torque to handle the harder and denser nature of metal. Additionally, wood lathes often have features such as adjustable tool rests and tailstocks to accommodate the unique shapes and sizes of wood pieces, while metal lathes may have features such as coolant systems and chip trays to manage the heat and debris generated during metalworking. **

The bow wood that is typically dark in color is Pernambuco. Pernambuco is known for its rich, deep brown color, which is highly prized for its aesthetic appeal.

It's important to work slowly and carefully to achieve the desired shape and smooth finish. **

To plane frame wood cleanly, start by ensuring that the plane blade is sharp and properly adjusted. Then, work with the grain of the wood, taking light passes with the plane to avoid tear-out. It's important to maintain a consistent angle and pressure while planing to achieve a smooth and even surface. Finally, finish by sanding the wood to remove any remaining imperfections and achieve a polished look. **

Dark brown wood can be lightened by sanding it down to remove the existing finish and stain. Once the wood is sanded, a wood bleach or wood conditioner can be applied to lighten the color. After the wood has been lightened to the desired shade, a new stain or finish can be applied to protect and enhance the wood. It's important to test any products on a small, inconspicuous area of the wood before applying them to the entire surface. **

Finally, you can stain or paint the wood to match the frame or create a contrasting look. **
