First find a level solid foundation on which to place your fire-board, then make a half turn with the string of the bow around the spindle, as in the diagram (Fig.16); now grasp the thimble with the left hand, put one end of the drill in the socket hole of the thimble, the other end in the socket hole on the fire-board, with your left foot holding the fire-board down. Press your left wrist firmly against your left shin. Begin work by drawing the bow slowly and horizontally back and forth until it works easily, work the bow as one does a fiddle bow when playing on a bass viol, but draw the bow its whole length each time. When it is running smoothly, speed it up.
Or when you feel that the drill is biting the wood, press harder on the thimble, not too hard, but hard enough to hold the drill firmly, so that it will not slip out of the socket but will continue to bite the wood until the "sawdust" begins to appear. At first it will show a brown color, later it will become black and begin to smoke until the thickening smoke announces that you have developed the spark. At this stage you gently fan the smoking embers with one hand. If you fan it too briskly, as often happens, the powder will be blown away.
As soon as you are satisfied that you have secured a spark, lift the powdered embers on the fire-pan and place carefully on top of it a bunch of tinder, then blow till it bursts into flame (Fig.8A). Or fold the tinder over the spark gently, take it up in your hand and swing it with a circular motion until the flame flares out.
Even to this day peasantry throughout the Carpathian and Balkan peninsulas build their fires with a "rubbing-stick." But these people not being campers have a permanent fire machine made by erecting two posts, one to represent the fire-stick and the other the socket thimble. The spindle runs horizontally between these two posts and the pressure is secured by a thong or cord tied around the two posts, which tends to pull them toward each other. The spindle is worked by a bow the same as the one already described and the fire is produced in the same manner.
