How not to use the Bow Drill
Here is a demonstration by Bear Grylls of how not to use the bow drill - sorry Bear! But, you only learn by your mistakes, and I made many when learning (and sometimes I still do) and I'm forever learning and experimenting and practicing. Bear's position and posture is all wrong for a start - no wonder he is struggling - he has nothing to stabilize his arm holding the bearing block so it's wobbling and he's not able to provide the pressure hence the squeaking - he needs to swap arms. The bow is a bit unwieldy , and the hearth doesn't have a notch! (hmmm not sure where that ember came from in the end....) Though I'm sure he learnt from his mistakes!
