Is this an oversimplification (such as for an Admirality Model) or how HMS Pandora would have been framed?  [ Edited Tue Jun 14 2016, 02:42am ] | ||

When I built my model I used the framing distribution shown in the AOL book and feel like is a lot closer to the framing of the actual ship than the HMS Eurydice print you posted. The Eurydice framing shown on this drawing appears to be incomplete so the drawing may just be a design sketch. Mike | ||

I am at the moment trying to make an actual surface rather than individual frames, because I hope that it will make the planking in CAD easier. I should be able to drape over surface or something similar that way. Another question: Is the bevel that the frames should have flat from one edge of the frame to the other? Or does it follow the curve of the hull? | ||

If you can change the surface to a solid it should be possible to cut sections at each frame location and adjust the thickness of each frame as required. That would be a fast and accurate way to generate the frames. Mike | ||

He was extremely helpful and explained to me that it is best to free-form the surface based on reference station lines which you add a certain tolerance to visually (red and green) in this case, 2nd Picture. I am happy with the Hull for now and will work on finding a way to generate a surface that matches the inside of the frames. My aim is to then use the page in the Anatomy of the HMS Pandora book that shows the frame layout to then 'cut' these frames out of the area between the outer hull surface and the inner frame surface. Does anyone have any suggestions on how to approach that inner frame surface best? At the moment I am thinking to do it the same way as the outer surface Rhinocentre helped me with. But if I understand it right the dimensions of the frames at the different futtocks is constant across the entire length of the ship? Perhaps there is an easier way to model this inner surface using that knowledge.   | ||

He sadly doesn't go into what method he used to arrive at his outer and inner surfaces. He also seems to have dropped out of the hobby at least he isn't active on the forum anymore. But it is great inspiration nonetheless. I think I will just try the same method I now am using on the outer hull surface and replicate that for the inner surface of the frames. | ||
