Abstract: A method of fabricating a wooden perch which is affordable, has a reduced chance of infection or infestation, and provides increased comfort for animals. The method of fabricating a wooden perch generally includes the steps of providing a piece of wood and using a wood crafting assembly to create natural, randomized contours along the exterior of the piece of wood to complete the wooden perch. The piece of wood is rotated along its length across a wood crafting assembly in two opposite directions to create an interwoven sine-wave pattern along its length. Random parts of the wood are then applied to the wood crafting assembly at random angles with random pressure levels to create a natural contour along the length of the perch. Mounting hardware may be included to aid in securing the perch to various surfaces, such as an indoor bird cage or an outdoor bird feeder.

The combination is configured and disposed on a tool rest so that, when the tip of the blade engages a downwardly moving surface of a workpiece, a vibration or chatter of the blade results and produces a three dimensional textured pattern on the workpiece. Pattern and texture may be selectively varied by adjusting the unsupported length of the blade (to control its frequency of vibration), by changing speed of rotation of the workpiece, by changing pressure of the tool blade on the workpiece, and by lateral and rotational manipulation of the tool.

Abstract: A method and apparatus for forming solid bodies by removing material from solid workpieces. A workpiece is situated between oppositely rotating tools which remove material from the workpiece, these tools having hollow interiors facing each other and each conforming to the configuration of one half of the finished body. The hollow interiors of the tools have teeth for removing material from the workpiece, and while the tools are rotated oppositely the distance therebetween is due so that from the workpiece a body is gradually formed, this body finally becoming almost completely enclosed within the hollow interiors of the tools, whereupon the latter have the distance therebetween increased so that the body formed thereby can be removed. These tools are adapted to form from a workpiece bodies of full circular or ring-shaped configuration, and the hollow interiors of the tools are provided with raised teeth similar to file teeth, for removing material from a workpiece.
