I dove into the project with my usual total lack of a plan and started slicing blue board thin enough that I could explore the inherent flexibility of the medium.
Here is the result;
she looks a lot better with some railings and such
the only parts that are not blue board are the dowel pegs in the railings
in thin sections the blue board is astoundingly flexible
even wide sections can be coaxed around some pretty tight curves
the parts around the bow curve both vertically and horizontally,
the hardest part was getting everything in place before the hot-glue set
I am starting to get the hang of blue board as a medium. It does have some serious limitations and cannot completely replace wood, but ib many cases, it will be my first thought for solid object construction.
I could really get into this stuff!
