When I teach groups about basic firelighting, I always get asked about the bowdrill method.
I tell them that it is easy once you know how.
How to make the bow, the hearth,the spindle, the bearer block etc etc
It took me a good few go's to get the right bits and pieces and make them work.
It's considerably harder to teach yourself, than to be shown how to do it by someone else, so very well done indeed
