Measure and centre 2 drill holes at the stern of the hull and drill two ø 3mm holes. Attach the wire connectors (9) with 5 washers (10- upper screw), 4 washers (10- lower screw) and 2 screws (19). Do not tighten just yet. 3 4 ø4 ø3 c I A F D J E L G K H M B Glue the template for the individual pieces (pages 9+11) together and glue to the plywood (2). Drill the ø 4mm holes and saw out all pieces as accurately as possible. Tidy up the sawn edges with sandpaper. 2 Glue the template (page 7) on to the second piece of plywood (2), drill a ø 3mm hole and cut out. Tidy up the sawn edges with sandpaper.
5 6 H 5a E A C B 5b I 5c Glue the template (page13+15) together, copy on to the aluminium sheet and cut out the individual parts with metal cutters. Clean up the edges with an engineer s file. Glue the individual pieces A, B,C,E, H + I together as shown. Let the glue dry properly. 7 D F G 8 5a 17 10 J K L 10 18 Glue parts E,F,G together as shown. Let the glue dry properly. Then connect both arms (L+K) and the head to the body (J) using the screw (17), the washers (10) and the cap nut (18)! Using super glue, stick the piece of aluminium (5a) to the top as shown, one piece at a time. Then cut off the excess with the metal cutters and file the edges flush. 9 10 5b 7 6 Bend the aluminium parts (5b) on one end approx.15mm by 90 and fit in. Cut off the excess at the end and deburr the edge. Glue in with super glue to create the seat as shown. Shorten the brass bar (7) to 115mm and deburr properly. Deburr the brass pipe (6) as well. Insert the bar to test whether it works. Add the propeller to one end. 3
11 12 ø3 15 5c Drill a hole (ø3 mm) in the bottom of the hull, 75mm away from the edge of the stern. File it with the a round file until the brass pipe can be glued into its future position without tension. Shorten the metal axle (15) to approx. 40mm. Wrap the rudder (5c) around the axle as shown above and glue it on. Then insert into the wire connectors (9) and tighten the screws. For measurements see point 11! 13 11 20 positive pole 14 120mm 13 12 4 16 Pull the silicon tube (11) over the motor shaft. Screw the motor (13) with the mounting bracket (12) and the metal screws (16) to the wooden bar (4). Strip the insulation from both sides of an approx. 120mm length of wire (14) and connect one end to the positive pole of the motor (marked red). Connect the black cable from the battery holder to the negative pole of the engine. Fit the unit to the hull in such a way, that the motor axle can be connected to the round brass bar through the silicon tube (11). Glue the motor in place with super glue. Align the pipe with the axle and glue in place (see illustration point 11), using 2 component glue! Make sure that the propeller can rotate. 14 15 3 M Centre the deck (M) and glue to the hull (1) with super glue. Measure and build a frame for the deck opening from the pine bars (3), fit into the deck opening and glue in, so that the strips protrude over the deck by 2mm. 4
16 17 Fit the switch (22) into the designated opening in the construction as shown. Connect the red cable from the battery holder to the central switch connector. Connect the red cable from the motor (13) to the outer switch connector. Then insert the batteries and place the top of the jet-ski on to the frame in the deck. 18 Place the figure you constructed in point 7 on the jet-ski and it s all done! 5
