It's easy to start using the full size Simple Rougher; just follow these 3 simple steps: 1. Position the tool rest as close to the work as possible so the carbide cutter is at the lathe center line. 2. Place the tool on the tool rest with the tool shaft parallel with the floor. 3. While securely holding the tool to keep the flat bottom in constant contact with the tool rest slowly plunge the carbide cutter into the work. When roughing with this tool and technique you'll notice right away most of the shock created by interrupted cuts during roughing is now absorbed in the tool rest instead of your hands and arms. As you begin to move the tool across the turning block you'll see how fast these carbide tools cut and how much simpler roughing is with the Simple Rougher.It won't be long until your block is a cylinder and you'll get your first look at what your turning will become. In addition to roughing you'll notice the Simple Rougher is a great tool for shaping the outside radius of a wood bowl and for turning beads on spindle turnings. Straight line turning is also simplified on projects such as the wishing well seen in the photos of this tool. Also it's a great tool for hollowing out the inside of a bowl. If you're making a box or other vessel that requires square inside corners and a flat bottom this is the tool of choice for that as well.
