Hammering Man in Seattle is 14.6 m (48 feet) tall, 76 cm (30 inches) wide and 18 cm (7 inches) deep, and weighs 26,000 pounds. He is located directly in front of the Seattle Art Museum and made out of hollow-fabricated steel with a mechanized arm of aluminum, an electric motor and flat black automotive paint. He was designed by Jonathan Borofsky and built in 1992 at a cost of $450,000. Original funding was provided by the Virginia Wright Fund in honor of Prentice Bloedel; City of Seattle 1% for Art funds; the Museum Development Authority and PONCHO (Patrons of Northwest Civic, Cultural and Charitable Organizations). Hammering Man´s arm "hammers" silently and smoothly four times per minute from 7 a.m. to 10 p.m. every day. It runs on a 3-hp electric motor set on an automatic timer. Hammering Man rests his arm each evening and every year on Labor Day. The sculpture was fabricated by Lippincott, Inc., North Haven, Connecticut and installed by Fabrication Specialities, Seattle.
