Now time to attach the noggings, two rows at approximately 800mm centres.  I attached these with screws angled into the uprights, two per end.   Once secured the stud wall was starting to stiffen well.  All that I needed to do then was to attach the two top plates, two 4x2" lengths stacked for the joists to sit onto.  I needed to use my quick clamps at various stages here and they proved very useful for this job.  >>photos<<
