This one is kind of a joke and an experiment in just how cheap you can build a guitar. The body is dry-erase board over plywood - no finish - with Tolex side binding. Dry-erase board is Masonite covered with Melamine. The neck is 100% Radiata pine, even the fretboard. The "inlays" are glitter and CA glue. The pickguard is the other side of the dry-erase board - 'chalkboard'. The pickup mount is a 57 cent switch plate.
Sanding is one of the most important aspects of woodwork, and luthiery. In general, if there is a choice of method between sanding and something else, routing for example, sanding is much safer and preferable.
