- Page 7 6.1.2 Study the drawing, firstly fold the top over through 180 degrees. Then fold the tabs and finally the sides. Note! if you use a vice when bending make sure it has jaw protectors. 6.1.3 Once you have completed bending the shape the ends can be soldered or glued. Note! once this stage is complete test the holder to see if it is watertight.
- Page 8 6.2 Planning and making the pump cover 6.2.1 Mark and cut out the shape of the cover on to the metal sheet (2). Drill the holes and remove any burr from the edges. Note: to make a better contact for the support tubes we suggest that you drill the holes to 6mm diame- ter and then widen them out with a punch to 8mm dia.
- Page 9 6.3 Making the dishes 6.3.1 Beat the copper discs (3,4) in a forming block until they take on the shape of dishes. Note: use a planishing hammer and a hardwood forming block. 6.3.2 Once you have made the shape mark out and drill a 8mm dia hole in each dish. Note: to make a better support for the dishes, firstly drill a 6mm hole and then widen it out with a centre punch to 8mm.
- Page 10 6.4 Making the supports 6.4.1 Mark out and saw the 3 lengths as shown from the brass tube (5) using a fine bladed hacksaw. Note: to avoid injury remove any burr from the ends of the tube with a file. 6.5 Part assembly of the support tubes and water dishes 6.5.1 Insert the tubes (5) into the copper dishes (3,4) glue or solder.

Page 11: Assembling The Water Pump
6.6. Assembling the water pump Tip: We recommend gluing the parts with two component glue or super glue 6.6.1 Glue the magnets in the drive wheel Note: Watch the polarity ( See diagram)! 6.6.2 Slide the drive wheel on the motor shaft as far as possible, with its open side facing away from the motor 6.6.3 Place the motor and drive wheel assembly from above into the pump housing, until the motor is flush with the housing. - Page 12 6.7 Final assembly of the water dishes and pump 6.7.1 Insert the water dishes and support tubes into the sheet metal pump cover (2) make sure they are upright and then glue or solder them in position. Note: the height of the dish (3) is determined by the pump. these tubes rest on the flat surface the height depends...
- Page 13 6.8 Assenbling the solar cells 6.8.1 Join the three 700 mA solar cells (not included in the pack) together as shown in the diagram using the brass connecting strips. 6.8.2 Make two supports for the cells from the remainder of the sheet metal (1). Use the diagram to mark them out and tin snips to the shapes drill and bend as shown.
- Page 14 6.9 Testing 6.9.1 Connect the solar cells and pump together as shown. The pump does not work: - if the water wheel (motor) is turning in the wrong direction the wire connections between the pump and cells will need to be changed over. - if the pump housing is not watertight check the motor.
