Day 10 Putting together half frames
Today we welded together the web and frame halves for stations 0, 1, 2, 3, & 4. We lifted each up and plumbed them to be sure they were centered and even left to right, then welded them to the headstock angle pieces. Then put in some bracing from the web to the headstock, and smaller braces out to just below the radius join. Suprisingly they were all pretty close to plumb center right off.  
It was then while lifting station 4 into place that we noticed that our tent wouldn't be high enough for stations 5, 6 ,7 & 8! A miscalculation on my part, forgetting to add in the height of the strong back! We'll have to raise it some before putting up the frames.

Day 10:
8 hours - Completed frames 0, 1, 2, 3, & 4 ready to go up.
