5.2. Planning and making the case:
• Cut two pieces 10 x 20 x 120mm from the pine strip (2) 10 x 20 x 250 mm
• Assemble all the parts as shown and glue them together.
5.3. Soldering the metal strip on the drive shaft, and adding the motor connectons:
• Cut a length 4 holes long from the holed metal strip (10) as shown in diagram. Remove any burr with a
file. See diagram 1
• Using a pair of side cutters make a series of cuts/identations in the drive shafts (23a 23b) as shown in
dia 2. These cuts are to ensure that the red gears (12) are a very tight fit on the shafts.
• Clean up any burr on the end of the shaft.
• Mount the holed metal strip on the end of the shaft (23a) and solder it about 3 mm from the end.
See diagram 3.
• Cut two lengths of insulated wire (32) each 150 mm long and remove the insulation from the ends.
• Solder one length to each connector on the motor (18)
• Finally mount the red gears (12) on the shafts where the cuts/indentations have been made ensuring
that they are both a tight fit, use a two component glue if necessary.
