During the first day putting up the oak frame, the end truss was not checked carefully enough and was slightly out of postion and not quite vertical, and I did not see the error until all the other trusses were correctly in position and braced to it. I asked for it to be corrected and was told forcefully that it was too late ! The mistake is visible in this picture, but is not very serious as the truss is hidden in the thckness of the insulated wall in the gable end.
