This photo gallery shows the development in constructing the keel, frames, and planking. Le Fleuron has 62 frames, most of them composed by 14 different pieces of overlapping timber originally dowelled together (on the model glued). In addition, there were 12 frames on the inner side of the hull.
The external planking on French ships at that time was fixed to the frames under the waterline by alternating wooden dowels (treenails) and iron nails and above the waterline by iron nails only (like everywhere on the model brass is used where iron was originally employed). To simulate caulking (both for external and deck planking) I have used black Bristol board glued to the sides of the planks before they are cut out.
