Hello, having ordered Nicks book from amazon.com, I am now lofting a Guillemot but have come across a slightly worrying problem. I have taken the cockpit area form offsets from this site but I get strange results with them. Form 8 is OK, but when I add the offsets to forms 9 and 10 they do not fit !! Its as if the extra offsets are too high, and I have checked and checked and checked....

Has anyone else experienced this ??

Perhaps, as is mentioned in the corrections page, the extra offsets are not really needed anyway, so should I just cut the forms with flat tops ?
