I am hoping to get some first-hand information into the wiki Bow-drill article about different wood combinations. I have added a couple of new sections to the article under Tips/Wood Choices – one for “successful wood combinations” and one for “difficult wood combinations”.
So far, the only data I have is from my own experience and from the pictures Urban Scout added to the wiki article.
If you have experimented with fire-drills and would like to share what kind of wood combinations worked for you, just reply to this post with what you used for the spindle and fireboard, and I’ll add it to the wiki article. (Or if you feel comfortable adding to the article yourself, feel free.)
