Just discovered a brand new species.
It still an ornithological mystery.
No live bird is ever seen, is it extinct?
What bird has a flexible rubber skull?

Join me on an expedition to excavate the unknown Bikebird.
and : finders-keepers. So whatever you like- its yours!

Step 1: Expedition Essentials

Now this is simple:
Inner tire
scissors
metal wire
pliers
something to make little holes (awl, revolver rod, strong needle)

Depending on the final application some base for a necklace, bracelet or earrings.

Step 2: The Skull-p-thing

Take a piece of inner tireand cut it in a sort of hockey stick shape. The pointed end will become beak, the curl will become head. You can try different variation with shorter or longer beak, or narrower and broader head. After you cut the shape, flatten it and pull the point of the beak through the loop.

that's all!
well, nearly.

Step 3: Stabilize Your Discovery

To secure the shape it is necessary to connect both sides of the head just below the beak. You could use needle and thread. I prefer a piece of wire. Stick it through the top of the head, out one "cheek" end in the other. Prepare holes with your revolver rod or needle. The piece of wire sticking out of the head can be shaped in a circle to attach the pendant to a necklace, bracelet or earring base.

Step 4: Subspecies

The very small mini species. Especially suited for bracelets and earrings. Find a very narrow inner tube ( racing bike). Cut as in step 2. When securing the shape with wire don't make a hole in the top of the head but use the existing slit instead.
In the last picture the results are painted with steel colored acrylic paint.

Step 5: Subspecies2, the Collared Bikebird A.k.a. Ring

The cutting of the shape is a little different. Just look at the pictures, and you will manage. No wire or any other attachements needed.
If you want you can paint with acrylic paint. Four of these make perfect claws for special occasions (Halloween?)

Step 6: Specifications of the Specimen

Of course:
the size of the tire determines the size of the skull.
Painting:
acrylic paint will stay on to a certain point. You can prepare with a basecoat of acrylic modelling paste witch sticks better on the rubber. I broke the paint on purpose on a few models, and secured the result with clear acrylic laquer.
Reshaping:
You can cut eyes bigger and cut holes in the beak for nostrils. This works best on painted models. The painting helps to keep the right shape. Non painted ones can become weak or dis formed.

Enjoy exploring.
