I wrote some articles for The Bushcraft Journal a few years ago on bow drilling including the component parts of a bow drill set, so take a look at and read in conjunction with this video. They’re good articles and have a lot of useful information., not just on the component parts of a bow drill set but also how to make a bow drill set, posture and technique, including variations if you can’t adopt the usual posture, and also for bow drilling as a group rather than individually.
I’ve put this video together to compliment those articles, sometimes it’s easier to see something than to read about it. In the video I describe the different parts of a bow drill set, what materials you can use to make them and also about different approaches to bow drilling.
We teach bow drilling on the IOL Bushcraft Competency Course. You can see loads of photos from this course, as well as all of our other courses, on our Facebook page.
