The sequence below shows the process of replacing the instrument panel and cleaning / painting the remaining bulkhead.  The old panel and its mounting were removed and all the old weld ground back; a cardboard template was cut to ensure that both ends of the loco were the same and that sufficient weld-gap could be made without having to grind away loads of 5mm plate; the replacement panel was tacked in and checked for alignment before being fully-welded; the whole area (including the other parts of the bulkhead which were de-scaled and cleaned) was painted in primer to protect the surface.
