Now we start removing the planking on the aft port section, taking great care to preserve the best template for the new plank, also to not damage the frames that need replacing, again good templates. These frames are replaced in oak and ash according to what timber we have to get the best grain.
The frames base lands on the lower gross frame. These are usually about 3 inch thick, much stronger, the reason being that the outside bilge keel will have through bolts to hold it in plage and an inside rail which settles on the frames above and the same length of the bilge keel this puts all the strength into the bottom of the vessel when all the bolts are in.
This creates a big clamp effect, keeping all the frames in plage, the frames at the base joint will have copper clenching in them but on the planking usually at 6 inch galvanized nail this is cut with an inch showing through then bent over into the frame with a man holding a big hammer on the outside. A good tip is to use a 1/4 inch drill to create a grove into the frame to take the bent over section this will allow the nail to be below the frame surface and a bit putty to tidy up frame face.
Several frames are replaced and primed.
