The bases are poured concrete, each must weigh 40 pounds. The lamps are head lights from a circa 1920 vehicle. The poles are the best. They are steel grain augers. At about three feet the center 3/4 inch diameter steel pole has been cut off and the lamps are allowed to adjust on the the springy part of the auger.
P.S. Check out Steampunk on Google. (http://thesteampunkhome.blogspot.com/). Its the name of the style that I've been flirting with for years. Victorian industrial meets digital. A very Jules Verne kind of feel. What would a PC look like if it was made in 1890 rather than 1990?
