hole. When the hole has been partially filled, allow the wax to harden a little, and then press it down around the nail with the end of a match, being careful not to throw the spool out of center by doing so. The hole should then be filled to the top.
We are now ready to prepare the clockwork for mounting upon the wooden frame. The works shown in Fig. 161 are from an alarm clock, but if you have a striking clock, or one with works a little different from those shown in the illustration, it does not make a bit of difference in the scheme for attaching the works. The three parts shown in the foreground of Fig. 161 must first be removed from the works. These will be recognized readily in any clock, as they are pivoted close together, and regulate the speed of the other wheels. When they have been removed, the mainspring will unwind rapidly. The frame of the works shown in the illustration is held together with nuts, so that in removing the wheels it was necessary to unscrew two of them, spring the frame open enough to let the wheels drop out, and then replace the nuts again in their former positions. If the frame of your clockwork is riveted together, the wheels will have to be broken out. A small silk spool, such as B (Fig. 162), should be fastened upon the small pivot which originally operated the clock's hands, for a belt-wheel. Lay the works upon a table with the face-side down, and, after centering the hole of the spool upon the pivot, fasten it in place with sealing-wax in the same manner as you attached spool B (Fig. 161).
