i am building the Billing kit (started many, many years ago, but retirement gives more time). I'm definitely an amateur in these things and don't have the skills to re-jig many of the details that Matti and others have taken on. The one thing that is really bugging me at the moment is the relative (vertical) positioning of the wales, to some extent relative to the main deck but very particularly with respect to the stern galleries and even more so, to the beakhead.
Billings give vertical offsets of the various wales from the main deck, but now details of how this translates at each end.
If anyone can help, ideally with some diagrams at galleries and beakhead, i'd be really grateful. I found Matti's photo from the message at the start of this thread very helpful, but would be interested to see any further dimensioned diagrams if possible (no offence, Matti - looks a great model)
Here is a drawing of the exterior that should give some idea of the relative placement of the wales, quarter galleries and beakhead. It is not the most up to date version, but it corresponds pretty well with the Billing kit hull.
