A little from this evening’s effort to fabricate a repair for this area. 

Rot and previous rubbish welding chopped out:

Repair panel made up. What a pig to do! The combination of a curved section and slight bend to the panel made this quite tricky to get right. There is also a dip in the panel on one side as it approaches the torsion bar. For that bit I had to weld an extra piece to the panel (I could’ve made the panel bigger and just bent it, but I’d already cut it down to size).Should do the job.

Trial fitted to the chassis, 

Heres the dipped section (sorry about the image quality). It’s not a perfect match for the original but should be a neat repair:

Got some paint on it tonight so should be able to mastic it tomorrow night and weld in Friday. Hoping to get the O/S outriggers in soon once these repairs are done.
