Crankcase; camshaft box; distributor:
Assemble the engine around the crankshaft mount(GR9-01). This will ensure that the parts line up properly. Be careful not to get any glue inside the crankshaft mounting tube.
Begin by attaching the distributor(GR9-09) to the crankshaft mounting tube(GR9-01) so that the tube end is flush with the gear side of the distributor. Slip one of the crankcase covers(GR9-07) onto the tube so that the detail side faces the distributor and line it up so that the nine rings on the distributor point between pairs of bolt heads. Next, slip on the crankcase(GR9-08) and the other crankcase cover. Glue the crankcase to the rear cover so that the drilled tabs on the dis- tributor will line up between each pair of cylinders(Fig.1/13). Before you glue on the front crankcase cover, align its bolt heads to match up with the ones on the rear cover.
Add the camshaft box(GR9-06) on the front of the crankcase, aligning the pegs dead center on each piston, slide the timing gear cover(GR9-05) onto the tube and then glue these parts together. Next, slip the nine cylinders(GR9-10) over the pistons and glue them in place, paying attention to the orientation of the spark plug ports. From the pilot’s point of view, they are at the outer end of the cylinders, in the plane of the engine, facing to the right. Glue in the spark plugs(GR9-13).
Attach the cylinder heads(GR9-11) to the cylinders so that the peg on each lines up with its twin on the camshaft box. Make any needed adjustments to fit the exhaust valve lifters(GR9-12) between the pegs. Paint, weather, and highlight the motor, should you wish to do so.
Complete this step by attaching the ignition wires(WP——— -) from the distributor to the spark plugs, referring to Figures 1/11-1/13. Cut nine 55mm lengths of wire. Thread each wire through one of the nine tabs on the distributor so that equal lengths emerge from each side. Twist the wire twice around itself at the ring, then run one end to each of the spark plugs at that cylinder and attach as in Figure 1/13. Trim off any excess wire.
Propeller group:
Referring to actual-size Plan D04 in the instruction booklet, laminate the three propeller layers(GR9-03), using the provided bolt-and-nut jig(J001) to properly align the parts. Once the glue is dry, remove the bolt and file and sand the propeller to its refined shape. The front of the laminated propeller is stepped to guide you in filing the correct shape. The back is then shaped to follow the front. Begin with the overall lengthwise curve, then proceed to the cross-sectional shaping. Note that the front surface is slightly convex and the back surface is concave. Take your time and check the cross sections on the plan often. When you are satisfied with the result, apply at one thin coat of var- nish or shellac. After the first coat is dry, lightly sand it with #400 paper to remove any grain raised by the varnish, then apply a gold-mahogany stain. When dry, follow this with a sec- ond coat of varnish or shellac. You can add a third coat of var- nish, without sanding first, if that looks better to you.
Paint, if desired, the front(GR9-02) and rear(GR9-04) pro- peller flanges before fitting them to the propeller. Referring to Figure 1/7, line up the molded-on front and rear bolt heads/nuts before gluing the flanges to the propeller. Dry fit this assembly onto the crankshaft mount. If necessary, file the end of the brass tube so that the propeller assembly snugs up to the timing gear cover, then, glue it in place.
