Now your staff ought to look like [Fig. 4], and you can commence ratling it down, for which half-inch rope ought to be used.
CHAPTER XLIV.—HOW TO MAKE A POCKET COMPASS AND TIMEPIECE.
By F. Chasemore.
For this, get a wooden tooth-powder box, plain—that is, without projecting rims—take off the lid, and smooth it all over. Next make the compass-card. Cut this circular, about a quarter of an inch smaller than the inside of the box, which should be about two inches and three-quarters in diameter outside. Mark the centre of the card, and mark from this centre the thirty-two points of the compass (as [Fig. 1]). Now make the needle. This must be hard steel; you can get this at the tinman’s or ironmonger’s. Get him to cut it about two inches long and three-eighths of an inch wide in the middle, tapering to a point at each end. The steel should be about a sixteenth of an inch thick. Get him to drill a hole through the middle of this steel about an eighth of an inch in diameter. Get a small piece of brass wire a quarter of an inch in diameter and a quarter of an inch long. File a shoulder to this (as [Fig. 2]) about a sixteenth of an inch wide and an eighth of an inch from the end. Drill a hole triangular in section an eighth of an inch deep and about an eighth of an inch at the outside. Place this through the compass-card. Now magnetize your needle. This is done as follows.
