BLOG ROLL Lady Liberty’s Favorite Look? Bronze.
Thanks to the meshing of old and new metalcasting techniques, a bronze casting of the plaster model Frederic-Auguste Bartholdi used to create the Statue of Liberty is now up for sale—at least to those who have money to burn, according to the New York Times.
One bronze replica of the model costs $1.1 million, and so far, two of the 12 bronzes have found homes with private collectors.
The plaster model was too fragile to be coated in silicone to make a mold. So a French company, 7Dworks, scanned the model and made a digital reproduction. This was sent to Fonderie Susse, Arcueil, France, which is using the investment casting process to make the fi nished bronze sculptures. Each bronze replica is 9.4 ft. tall and weighs 1,000 lbs. It takes 600 hours to create just one.

ONLINE DISCUSSION Diffi cult Lessons Learned
MODERN CASTING recently posted a blog entry about Boeing’s problems related to outsourcing the design and manufacture of its 787 Dreamliner. Readers’ responses were both sym- pathic and reproachful. Following is a sample of what people had to say:
“Cultural differences, ethics and business practices play a major role, [and] Boeing assumed [foreign fi rms’] working practices mirror[ed] their own. Oh dear; what a very expensive assumption.”
“This is, unfortunately what happens when you have management with nothing more substantial than a business degree. Bring back engineers to run companies!”
“While the technological deficien- cies in the article cannot be denied, the outsourcing motivation was not completely about saving money. By outsourcing engineering contracts to these other countries, it also helped to firm up orders for the Dreamliner from the primary airlines in each country.”
