Attic Base
Design
Attic
Bases are used with the classical Orders of columns
Doric,
Corinthian, Ionic,
Scamozzi, Composite, and
Temple of the Winds
(Tower of the Winds). Unlike the
simpler
Tuscan Bases, Attic Bases have
two rounded profiles (Torus) that are
separated by a hollow concave or recessed area (Scotia) that sits on a
Square Plinth. The Torus and the Plinth in some cases can be made separately.
|
|
 |
Sizing Your
Replacement Bases
Measure the
circumference of the bottom of the shaft before it engages the base. The best way
to size the base is to tape a piece of string to one side of
the shaft, go all around the circle and note the length. The length of the string is the
circumference of the bottom of the shaft before the base. The length
times 3.14 will
equal the diameter required for the hole in the base. You need wiggle
room so add a 1/4". Before considering custom sizes, select from
the standard models below.
