The last of, approximately, 4000 bolts and nuts is into the last of the arches.
Time for a rest and refreshment. That's water in hand. Where's the beer???
Progress has been slow since these pics were taken. Had a talk with the factory engineers about the end walls and door frames. Got some things cleared up and getting ready to erect them this week.
Will it ever end? Will there ever be water in the "cooling Loop"? There have been times when I doubted it.
