The Drill Gets Shiny

Sometimes, as a result of friction, the drill can become polished and shiny rather than charring and producing heat. The shiny polished surface produces much less friction and won’t produce an ember. The picture below shows an ivy drill and hearth which has become polished, to rectify this a new point needs to be carved onto the drill to remove the polished wood.

This may be a problem with the material you have selected, perhaps you have selected a very hard wood such as oak which will produce very little friction and polish easily, but this is not always the case. If you are sure you have a good wood for bow drill fire lighting (such as the ivy pictured on the last page) but it is still polishing up and becoming shiny you need to carve off the polished point and begin drilling again. You could also try dropping a few grains of sand into the depression in the hearth to increase friction.
