Day 3 (Thursday -- Jazz means improvisation)

Well, today was critical. At the end of Wednesday Dan observed that the next six hours of sculpting determine success or failure. This is where we have to make all the curves and surfaces come together. And while one can patch the occasional square inch, one cannot really correct for larger mistakes. In that way it really is like sculpting marble or granite. And I am pleased to report that all went well today. The sky was cloudless as usual, but the snow is pretty cold (18 degrees in the middle of the block). We set up some shading that worked quite well during the warm hours. And we really learned from mistakes of past years how to proceed slowly and get it right. So at the end of the day we have the shape we want and we think the strength is there for it to hold up for a couple more days. Tomorrow, Friday, we can work from 8 am through the night to the next morning. So we will try to define the struts that we will leave in place and then, on Saturday morning, remove them, slowly and carefully, with a keyhole saw. Many people walking by think it won't stand up. We love to hear that! We are pretty confident that it is okay, even though it has hardly any negative curvature, which, we think, was the key to stability in earlier years.

At the start of the day we made a big spur-of-the-moment decision to remove the base. This will make the sculpture taller, but of course it changes many measurements, as well as eliminating points from which we measure. Well, there is no real need for measurements now! David was very good at adjusting the sculpture plan to account for this, and it appears to be a good decision.


This year we used a lot of spray paint. I hope it all comes out when we shrink down by rasping! Just behind me you can see the elephants that the New York team is sculpting.

As the sun goes down, the temperature drops very quickly. This week the highs have been in the 30s, and the lows near 0. This is pretty much okay so long as one budgets for about a two-inch loss per day on the south side. Here sculptor and designer David Chamberlain surveys the spine of Cool Jazz.


We attached sails to the scaffolding for shade, but there was no need to take them down after sunset; that way they prevent moonburn. In this view, taken at 8 pm on Thursday night, the shape is pretty much there.
