On Friday 12 August I recieved a phone call from Neil E who had been at the yard to collect nb Lodestar after some paintwork by John . He had been watching Dave at work measuring up prior to fitting the cabin framing and could hardly believe that Dave was remeasuring and remarking because a 1/16" error had crept in on a 44'6" cabin.
Wondering if this was true, as Neil E is a winder upper, I have since asked Dave if actually did this. He admitted that he did contending that it is easier to get this spot on than deal with a 1/16" error later.
An engineer from the aircraft industry who has worked on the Boeing 747 commented even a 747 may vary in length by almost a foot.
