The rear sheet is in place, and is held from shifting by two temporary bolts. One of the bolt heads is holding up the leg of the square. The front sheet has been positioned for laying out, from underneath, of the sheet's finish size and corner contour. The sheet will be removed from the tank, and placed on horses for torching and grinding of its edges. The front to rear dimension of the sheets were not in need of any trimming.
