CHAPTER X.
WIRE WINDING APPARATUS.
127. Winder. Fig. 68. In case you do not have any means of making a smooth hole for the "bearings" of the winders of [App. 93] and [94], you can use a spool for the purpose. B is the end of a piece of board about 1 in. thick, 3 in. wide, and 6 in. long. The spool, A, is laid upon this, a band of tin, T, being used to hold it down firmly upon the end of B. Screws, S, hold T down. A stove-bolt axle ([See App. 93]) is shown, and by using a nut, as explained, bolt magnets may be wound. By using the handle of [App. 92], this arrangement can be used to wind almost anything, when used together with the attachment of [App. 95].

128. Crank for Winders, etc. Fig. 69. This form of crank or handle will be found easier to make than the one in which a wire is expanded in the slot of a stove bolt, and it can be used for many purposes, especially where dowels serve as axles. Wrap a little paper around the end of the ¼ in. dowel, D, and push it part way into the spool, A, then put in a set-screw, S, to keep A from twisting upon D. The straight end of the wire, H, should be put into a hole, B, and another set-screw used to fasten it into the spool.
