Hi folks, is there a 'paper' way to develop the 'flat' plank shapes from offsets and lofted lines?


Certainly there is. It is called "spiling". Try
http://tinyurl.com/p4qymfk
and click on the first entry - Planking a Carvel planked boat
which should get you a PDF from the Pennsylvania State University
or
http://www.boat-building.org/learn-s...ank-templates/
which has a video and instructions.

there are several other sited on the same page that cover things

In rough terms, you simply divide the length of each timber (rib) by
the number of planks you will use and that gives you the width of the
plank at that station.

That is not an exact measurement as you likely will have to allow for
the outgage and perhaps for having to hollow the back of the plank to
fit a timber.

Good links Bruce, thanks. I would argue however that creating cutting
templates on the framing is not quite the same thing as lofting
dimensions from the plans. There may be a way to do it with computer
design systems, at least for larger pieces of steel, aluminum or
tortured plywood.
