4. ASSEMBLE AND ADJUST
4a. To simplify construction, you can trim and connect both
motor wires to the battery pack directly. This way, you turn the
car on and off by popping one of the batteries in or out. But to
make my latest Gyrocar easier to operate, I wired a small switch
into one connection.
4b. In the rim of the plastic cap, cut 3 slots about ¼" long each,
sized and spaced to accommodate the 3 screws on the circumference of the large disk.
4c. Now put the Gyrocar together by fitting the cap over the
3 screws on the disk. Run the motor and fix the cap’s position
so that the gyroscope doesn’t press against the track wheel
constantly, but only when the Gyrocar is resting on the track
wheel and the thin plastic cap flexes slightly under the gyroscope’s weight.
4d. Finally, adjust the screws that hold the drive wheel bracket
to the cap so that the Gyrocar remains upright as it runs, rather
than leaning to one side. You want to center the Gyrocar’s center
of gravity, and the holes in the bracket are large enough for some
adjustment room. That’s it; you’re done! After these 2 adjustments are made, you won’t have to make them again.
