One who thinks that the driving of a nail simply consists ingetting the whole length of it out of sight, has little conceptionof the real nature of the operation. A nail driven by an expert HANDY MAN S WORKSHOP AND LABORATORY 83 will often hold several times as much as one ill driven; while,too, it is often made to draw the parts into place. If you haveever watched a mechanic driving nails, you have doubtless notedthat he rarely drives one at right angles with the face of thework. There is a reason for this. Suppose that he is nailingthe sheeting on the frame of a building, and desires to drawthe board down tightly against the one below it; he points the. Fig. 95—Nailing a butt joint nail downward, and a few well-considered blows at the last pro-duce the desired effect. If the board is bent edgewise, so thatmuch force is required, probably he will start the nail in the upperedge, pointing very sharply downward. Again, two nails drivenin a board at different angles will hold it in place much morefirmly than the same nails would if they were driven in at rightangles with the face of the board. 84 HANDY MAN S WORKSHOP AND LABORATORY Did you ever notice that, in driving a nail in very hard wood,one man will do it successfully, while another succeeds only indoubling the nail up before the point has fairly entered the wood ?The difference lies in the fact that the expert strikes the nailfairly, and not too hard, coaxing it in; while the other strikestoo hard and with indirection. It may be mentioned, right here,that in driving a nail into very hard wood, it is usually profitableto dip the end into oil
