Static Lumbar 2
As with Static Lumbar 1, the
compression elements in this piece are ten tetrahedrons, but each
one is a different shape. In a regular tetrahedron the interior
angles of all 6 slats is 110°. In Static Lumber 2, the interior
angle of the top and bottom slats is different from the other
4, and range from 140° at the flattened bottom element, to
50° at the elongated top element. The wood in this piece is
Madrone, which is a harder wood than the Red Cedar in Static Lumbar
1, and holds a fine edge better. The wood is all hand planed,
and the crisp edge details help creat the flavor of the piece.
