—[Fig. 82] illustrates the position to be taken in horizontal boring. The head of the brace is held steady by bracing the body against the hand which holds it.

To tell whether a bit is boring a hole in the direction which is wanted, it is necessary to sight the bit and brace from two directions at right angles to each other. In horizontal boring, the first sight should be made while in the position shown in the illustration. The second position for sighting would be obtained by inclining the upper part of the body until the eye is on a level with the bit. In vertical boring, [Fig. 83], the sighting of the bit would be done across the piece, then along it.
Changing from one position to the other can be done easily and without interfering with the boring and should be done quite often, until the bit has entered well within the wood.
[Fig. 84] illustrates a position which is frequently taken when boring in hard wood, or when using the screwdriver bit on large screws. The chin, resting upon the left hand, steadies the tool in the first case, and can be made to give additional pressure in the second.
