Transcript of movie: To build a home or other building the builder first needs to turn trees into timbers. After chopping down a tree and removing branches, the builder chops notches along the length of the tree on four sides using his axe. Next, using a broad axe, he chips and pries the bark and wood away between the notches to flatten the surface of the tree to make it square. Then he uses an adze to smooth off each side.
