PREPARING THE SPINNER:
The plastic spinner cone supplied with this kit has a unique shape,
peculiar to the Bf-109 and is supplied uncut. This is to allow the
builder to use it for a 2 or 3 bladed prop for either flying or display.
Finishing this spinner is not difficult but does require some care.

Note that mounting this spinner requires an adapter nut that
threads onto the shaft of your particular motor at one end and is
tapped for an 8-32 bolt on the opposite end.

C.B. Associates

makes these adapter nuts in any size that you will need. You will
also need an 8-32 x 3/4" socket head bolt and a several #8
washers for use as spacers.

For the following steps, locate Bag #13 containing the spinner
parts.

❑

1) To locate the cutout locations for the blades of a two bladed

propeller, start by drawing a straight line across the back surface of
the plywood spinner backplate, exactly through the center of the
prop shaft hole. On a flat surface, place and hold the spinner over
the backplate and use a pencil to transfer the two opposing edge
marks onto the back edge of the spinner cone.

Note: If you want to use a three-bladed propeller, use a compass
to make three pencil marks at 120

O

apart.

❑

2) Cut out the propeller template found on page 16. Align the

leading edge of the template with one of the marks on the edge of
the cone. Tape the template in position and trace the outline of
the blade cutout onto the cone.

Move the template over to

the opposite mark, tape it in place and use pencil to trace the
remaining blade cutout outline. The prop blade cutouts are now
made in the spinner. To make this relatively easy and accurate, we
used a Dremel

®

Tool with a highly tapered sanding bit, followed by

sandpaper to smooth the edges.

❑

3) Use thick CA glue or 5-minute epoxy to glue the two 20 mm

dia. plywood washers together with their center holes aligned.
Glue the laminated 20 mm washer assembly to the inside flat nose
of the plastic spinner, aligning the center hole with the molded
"dimple" on the inside of the spinner.

Use thick CA glue or

5-minute epoxy. After the glue sets, use a #19 (.166 dia.) bit to drill
through the front center of the spinner, at the dimple mark.

❑

4) Place the spinner backplate on the motor shaft and then,

the propeller. Tighten these parts in place with the adaptor nut.

Insert an 8-32 x 3/4" bolt into the front of the cone and place about
4 washers on the bolt on the inside of the spinner. Thread the bolt
into the adapter nut and adjust the number of washers on the bolt
until the skirt of the cone is just even with the bottom of the
plywood backplate when the bolt is tightened down. This spacing
will remain the same as long as you replace the prop with an
identical prop. Changing brands and/or sizes of props will more
than likely change the required amount of shims.
