#527 In the field: Brookgreen Gardens workshop, con't . . .

Start this series with  #522,  April 16, 2014.

I post bird anatomy and armature building on this blog as a review and continuing education for students.
One of the most frequently requested subjects concerns my method of constructing a "cantilever" armature
which supports the projected wings of birds in flight.

The dictionary explains "cantilever" as a projection, fixed at one end, that is used in construction.

Below, are two different versions of the "cantilever" armature set-up using 1/2 inch plumber's pipe, floor flange, "T-joint"
and tie wire . . . all materials that are available at a hardware store.  Strength and stability is
achieved by packing clay around the "T-joint" after inserting loosely twisted tie wire.

The top picture depicts the armature set-up with a double loop of wire for a wingspan in excess of 20 to 22 inches.
The second photo depicts a single loop twisted wire set-up for wingspans of a shorter length.
Please note:  Each loop is made up of TWO wires, loosely twisted together.
The single wire was placed to denote the wingspan [in inches] of the species to be modeled.

Below, aluminum foil is used as a vehicle to carry the warm clay and to cantilever and project the wing shape
into space . . . a wingspan exceeding 30 inches can successfully be constructed in this manner.
A thorough explanation of the "cantilever" armature system is available in my workshop and I invite workshop
participants to follow along with their own work as I demonstrate the amazing strength of the armature.

Below, as I demonstrated the armature system by modeling a duck with outstretched wings in the workshop,
a student followed along and depicted a barn swallow in flight.

Below, are examples of block-ins and works in progress of birds in flight using the "cantilever" armature system.

Below, are examples of cast bronze sculptures of birds in flight . . .
I used the "cantilever" armature system while creating these works.
