Achilles Last Stand - Part I

The cabin roof was too badly damaged, so we built a replacement.  First steel bars were notched, then bent and welded to form curved beams.  These were then welded to a sheet of steel, forcing it into a curve across the roof section

 Turning this over, slots were cut across the roof at intervals.  When welded up, these slots pulled the roof into a curve along its length forming a compound curved roof panel.

 A trial fit, a bit of a trim, then welded into place.

A couple of strips of "rivets" down each side, and the roof is on, with a very pleasing compound curve.
