    This program illustrates the six steps of preparing a piece of lumber for use in a woodwork project. It employs the acronym, FEWTEL, as a way of remembering the sequence of these steps: F: Face side; E: Face Edge; W: Width; T: Thickness; E: End; L: Length. A student using hand tools demonstrates each stage in the process, but mention is also made of the use of machine tools.
