4. Mark the copper tracks on the electro board (see pattern on page 11)

for drilling and the slot. Photo 4

5. Hold the electro board carefully in a machine vice and carefully drill the holes ( see pattern on page 5)

Important! Too much pressure can snap the board in two!!!

6. Use a fine metal working saw to remo-ve the slot marked on the board. Then finally mark out and saw the board to the correct size ( see pattern on page 11) Work carefully as it is easy to break the board at this stage

1. Mark out on the welding rod (3) the following measurements, one piece 2 x35mm, one piece 1x30mm and one 1x50mm

2. On the second welding rod mark out 2 x 95mm long pieces

3. Use a pair of metal bolt cutters to cut the welding rod in the marked places Photo 3

Remove any sharp ends with a file

7. Slide the worm gear on the motor shaft. Slide it on so that the end of the shaft is at the end of the gear.

8. Place the electro board over the worm gear so that the 7mm hole in the board locates on the motor

9. Fix the board to the motor using a ma-chine screw (11 )and two washers (14) as shown in photo 9

10. Insert a machine screw (6) from the rear through the 3mm hole in the electro board and the add a nut (13) . Once this is in place do the same with the second hole Photo 10

12. Place a connecter over each of the machine screws as shown. Leave about 1mm gap then lightly tighten the side holding screw (12)

13. Take a double gear (20) and saw off the small gear. To do this place the gear vertically in

a vice.

Note ! try not to damage the plastic teeth in

the vice

14. Mount the gear in between in the middle hole in two connector blocks using the 50mm welding rod as shown. Make sure that the axle is in a central position and the gear engages with the worm

Photo 14

Note: The gear must engage freely with the worm drive and not stick as it turns

15. Carefully saw out the shape of the gear (20) as shown in the pattern ( page11) To do this first mark them out , then enlarge the middle hole to 4mm dia . Finally saw / file the shape as shown in the pattern. Repeat this process with the second gear

16. Slide the sawn out gears on the ends of the 50mm axle as shown and test the running action

The gears should engage easily and turn quietly when rotating the axle. Adjust if necessary

Photo 16

17. Cut the seat for the boat from the plywood sheet (2)

and trim it to fit. Use the two compo-nent glue to fit the

the seat in position ( see pattern on page 6)

Note! Use the pattern for the correct size !

18. Glue in place the 35mm and the 30mm pieces of welding rod in a an upright position as shown in the pattern on page 9, see photo 18.

Use 2 component glue

35mm

30mm

Note: It can take up to 20 minutes for the glue to harden depending on the make

INSTRUCTIONS

21. As shown insert the handle of the oar through the connector block and carefully tighten the screw 12

The whole arrangement should work freely in a rowing movement

Photo 22

22. Once the oar works easily slide on a distance piece (20) as shown in the photo 22

20. Take a connector block and insert a grub screw (16) so that a max of 2mm protrudes ( use instant glue) Screw the free end of the grub screw in a second connector block so that this can just about turn Diagram 20

Photo 21

Photo 20

23. Bring the connectors in the correct position : Between the distance pie-ces and the connector block should be about 10mm

Finally tighten the connector blocks Photo 23

27. Lay both of the forearms on a board in a mirror image next to each other . Using 2 component glue a screw eye (18) in the slot on each end to make a hand

So that the screw eye is not twis-ted place a piece of scrap under the eye

Photo 27

26. Use the plywood sheet (2) to make the rower. Trace the parts of the rower on the wood (Pattern on page 7) Use a fretsaw and then sand all the edges. Drill all the holes as shown It is best to drill all the holes first and then saw out the individual parts

Photo 28

28. Join the parts of the arm ( f+g) with the nails (16) in the pre-drilled holes

Carefully snip off the protruding points of the nails leaving about 4-5mm standing up

Note

For a functioning rowing action it is not necessary to

to make the rowing figure. If you wish this can be made at a later date

Before assembling the rower it better to have all the parts painted and de-corated . We recommend using any Acrylic paints

19.Saw out the blades for the oars, see patterns

Coat the free ends of the wire ( blades / 95mm ) with 2 component glue and then mount the blades on the wires

Photo 19

Photo 25a Photo 25b

25. Mark and saw out the rudder, see pattern on Page 7 Fix the connector block with 2 screws (9) The

top screw has 2 washers before the nut (14) The washers act as a fixing clamp for the wire handle

Photo 24

24.The parts for the boat stand are made up from the plywood sheet (2) Saw them out and sand the edges

Patterns can be found on page 7 Assemble and glue the parts to-

gether as shown

35. Place the mechanism in the boat so that it can be glued in place. It is to note that the oars are placed so that they make a line with the drive shaft and that the oars in a straight line and in a vertical position. ( 12 ‘oclock) ( see diagram 35a+35b)

Place the oars in the rowlocks .(This is easiest when the oars are in the 9 o’clock postion) If this is not possible the rowlock connectors need to be loosened and adjusted

NoteThe direction of the mechanism

INSTRUCTIONS

33. Glue the two halves of the body (e) together with the arms mounted in position

34. Glue the two halves of the head together ( part a) on to the body (part b)

31. Then add another two nuts (13) and assemble the arm (f+g) Leave about a space of about 3mm between the first nut and second pair

32. Then add 2 washers (12) to the arm (f+g) so that it can move easily . Make up the second arm the same way in a mirror image Photo 32

29. Insert a machine screw 10 through the hole in part e

INSTRUCTIONS

36. Glue the rower on the seat as shown so that he sits directly on the mechanism

37. The oars go first through the hand ( Screw eye ) then in the sawn gear, see photo

Photo 36

Photo 37

39. Cut 2pieces x100mm from the cable (4) and remove the insulation from the ends ( ca 5mm ) Solder one cable to one end of the battery holder and an end of the other cable to the opposite end of the battery holder.

The free cable ends can now be fixed to the tabs on the solar motor Photo 39

Photo 39

40.When a 1.5volt battery is inserted the mechanism should turn the oars and arms in a circular motion. Should the arm movement jam or be stiff check the joints and adjust them until they move freely

Photo 38

38. Slide the connector block on the wire for the oars (35mm ) so that the handle of the oar cannot slide out of the screw eye and gear ( see photo 36) Carry out the same technique with the second oar
