I recently demonstrated how to make a bow drill friction fire. This video shows the technique from start to finish with my explanation of the process. The parts of the set include the spindle, hearth board, bearing block, bow, ember catch, and tinder bundle. For this example, the spindle and hearth were made of basswood. The bow is made of oak and paracord. The ember catch is a small, thick piece of birch bark. The tinder bundle is largely grass with some goldenrod flowers and cedar bark.
