The engineering is ingenious on a bowsaw, and J. Crate Larkin explains in this article how to make and use this tool, which despite its primitive look serves many useful needs. He describes how to find, sharpen, and tension the blades and build your own wooden parts. A template is included in the article, as well as descriptions on building the brackets, stretcher, handle, knob, and key, and where to find a cord. Assembly directions are straightforward.
