Wellspring Africa's While I have yet to finish my book on the hand powered percussion drill (and doubt that it will ever really be "done"), I have been selling drafts like hotcakes. This is a reasonably well-illustrated 80-page book provides drill designs, drilling tips and tricks, a little history, and good background information on groundwater. As well, I have prepared a 12-minute video (NTSC or PAL) that explains how the drill works. Either item costs $15 (essentially the duplication costs), including shipping in the US. (Contact us about shipping books and video overseas. It can get pretty pricy. You're usually better off purchasing the CD and printing your own copies.)
