In the end decided to do this in 3 pieces as the paper templates fit nicely on a small sheet of 1mm cold rolled.
And cos I'm a piker!
Traced and cut with the jigsaw, and after bit of work with the hammer/sandbag/press/spanners got this to fit.

For the next small piece I added a drain hole for all the water that will never come down here. Might put one on the other side too.

You’d think as I have done one side that things would go easier second time round for the main wing - Nup. Here it is all marked up. 5 folds and a rib - easy.

So 4 hours later after pressing the rib a second time to get it to line up at the join, and refolding (twice) the main vertical that joins the subframe wall at the top.

Prepped to weld

Before I started cutting out the old metal I measured across the sub frame walls - 1052mm. This may or may not be close to what it should be (should have asked), but its what it was and everything bolted together so using a clamp I spread it to that measurement.

Welding in progress. A few clamps here, but nothing is forced to get the lines right. Lesson learnt from the other side.

Plugged and butt welded. The original metal is pretty thin so had to chase a few blow throughs. Bit of splatter too which was contamination from the easyphos I put on the metal to keep it shiny. Forgot to wire brush it off.
