SEQUENCE DRAWING OF MANUFACTURE - 1

V. Ryan © 2006 - 2009

 

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.
