SEQUENCE DRAWING OF MANUFACTURE - 1 |

|
|
1. Cut out the shapes for the card base and bodywork. |
|
|
|
|
|
2. Shape / form three art straws to the frame of the
model car. When folding/bending the straws, place the straws on top of
the card base to ensure that the straw frame matches it in size. Then
sellotape the art straw frame to the card base. |
|
|
|
|
|
3. Cut a rectangular slot at the front of the card
base, using a craft knife. This must be accurately cut as the front
wheel should fit precisely in position. If the rectangle is too large
the front wheel will move from side to side when the finished model is
tested. This will make the model move in circles rather than a
relatively straight line. |
|
|
|
|
|
4. Solder short red and black wire to the motors.
Check that red is soldered to the positive terminal and black to the
negative terminal of each motor. Fix the motors on to the polystyrene
motor base, using insulation tape. |
|
|
|
|
|
5. Turn the polystyrene motor base over and connect
the red and black wires to the electrical connectors as shown in the
diagram opposite. Then connect a further long red and black wires to the
opposite side of the connector. |
|
|
|
|
|
6. Sellotape the motor base to the straw frame/card.
Be careful hoe the model car is picked up as it is not a strong
structure. Lift the model by the motor base otherwise the model could be
damaged. |
|
|
|
|
|
7. Carefully turn over the model and use insulation
tape to fix the axle to the card. Then turn over the model again so that
it stands on all four wheels. |
|
|
|
|
|
Completed card and frame shown below. |
|
|
|
|
8. Cut out the bodywork card and draw a design that
reflects the theme of a racing car. The card can be pushed into the art
straw frame quite easily. In fact the bodywork can be interchanged so
that the model has different bodywork each time it runs/races. |
|
|
|
|
|
9. Finally connect the solar panels and, if in
England, wait for a sunny day. ‘Flick’ the switch and the model car will
move either forward of backwards. Switch the wires at the solar panels
terminals to alter the direction. |
