David finished his first production run of North Star last week as we were dealing with the lack of power in the Hurricane Irene aftermath. Timing worked out because David was up to final assembly and testing, neither of which requires much electricity.
David is going to have to adjust his schedule when working on sculptures like North Star. It has an incredible runtime of over 40 hours on a single winding. He has always tried to get each sculpture to finish two complete windings in the testing cycle. North Star remarkably just takes too long!
In the early days of Wood That Works David often heard the question, "Can you make it run longer?" I don't expect many will ask that now.
North Star has mesmerizing optical patterns. Two of the visual phases are shown above. You can view a video of it in motion here.
