First job today was to apply grey paint to the frame timbers that will be in contact with the aluminium cladding.  Next, while this dried, cut out the remaining steel gusset  plate.  Then I marked and  pilot drilled the mounting holes in one of each pair of plates.  I just had time to line up the first one on the timber cross bearer and drill through the pilot holes.  These will later be through drilled 1/4″ for the mounting bolts.  Once the  reinforcement plates are painted and mounted, the repairs to the nearside frame will be pretty much complete and attention can turn to the boot and boot doors.
