Figure 282.—Drill (auvili).

The drill of average size consists of an upright stick about 17 inches long and barely 0.5 inch in diameter. The stick (1) also receives the name of vili. A wooden disc (2) about 4 inches in diameter, perforated with a central hole, is run up on the stick to about 6 inches from its lower end and kept in position if necessary with wooden wedges. The lower end of the upright supports the boring point (3) which may consist of a stone flake and in some cases of a spine of the vana (Echinus). The point is thus called mata (point) or matavana or simply vana from the Echinus spine. The point is lashed to the upright with fine cord. The handle ('au) consists of a crossbar (4) of about the same thickness as the upright and about 7 inches long. A piece of sennit braid or twisted cord is tied by its middle round the upper end of the upright with a clove hitch (5). The two ends are then tied to the ends of the crossbar handle so that when the handle hangs down it is about an inch above the balance disc.
