- Drill holes in remaining washers. Holes should be just large enough for wire to pass through snugly. Cut washers out
- Cut three pieces of wire, each 3 inches long. These will be the gear shafts. Sand the wire, using a fine grade of sandpaper. This will make for a better bond when the gears are glued to the shafts. Make sure wire is as straight as possible
- Re-check holes in framework to make sure wire can pass through and rotate freely. Then, set shafts and gears into position on framework, placing the large gear at the bottom, the small gear in the middle and the rocker at the top. (For each gear, pass wire shaft through appropriate hole in the framework. Slide the gera and attached shaft guide onto the wire and then pass the wire out through the hole on the opposite side of the framework.)
- Center gears on shafts. Then turn the bank on its side and place a drop of super glue at every point where gears and gear shaft wires meet. With the bank on its side, glue will run down into the shaft guides and bond them firmly to the wire. Let dry for at least five minutes. Turn bank on its other side and place drops of glue on the other side of the gears and gear shaft wires. Let dry for five minutes. For a strong bond, be very careful not to move or in any way disturb the gears until you are sure the glue is completely dry.
- Align gears by moving shafts until gears are positioned as shown in the diagram. chek to make sure that neither the gears, the shaft guides, nor the pins on the rocker touch the framework. When alignment is corret, slip washers into place on each end of each gear shaft. Leave a small space, the thickness of a piece of cardstock, between the washers and the framework. Glue washers to gear shafts, using super glue. Be careful not to glue the washers to the framework.
- When glue is dry, cut excess wire, leaving 1/2 inch on the top shaft for the pendulum (see illustration) and 1 inch on the bottom shaft for the coin wheel.
Note: At this point it is a good time to check the operation of the gears. Turn the bottom gear, making at least one complete revolution, to see if the gears mesh smoothly. If the gears don't work, or if they work awhile and then stop, something is wrong. Check the list of things to do if your bank won't run, included at the end of these instructions. Locate the problem and make the necessary adjustments. The bank is easier to fix at this point than it will be later on when all the pieces are in place.
