6.4
I stick a 2 mm thin wooden lath, connecting the marks on the stations with clamps to the frames and mark the top side of the wale (upper side of the lath) and the top side of the lower top timber (under side of the lath). As can be seen on the third picture: the lower top timber of many frames is to high.

The frames of my shrimper are made of two layers of futtocks of which the one top timber is longer than the other. The longer top timber will later be a part of the railing. The waterway has to come on top of the lower top timber, therefore it has to end exactly two millimeters (deck plank thickness) below the top of the wale. On my model that is not yet the case.

Part 6: Planking the hull
6.1
Next step will be the planking of the hull. I want to start with the wales to add strength to frames. Before doing that I need to have some a more detailed view of the inside structure of the ship. The base drawings of which I dispose are not meant for POF build, so they do not show any details of the inside of the vessel. My main documentation recourses are the books 'Van boom tot schip' (From tree to ship) written in the seventies, about a decade after the last wood shipyard on our coast closed. One of the last shipbuilders described the building of a wooden trawler in a booklet for cultural heritage. A second book is more recent: 'Nele', a description of the construction of a scale 1/1 replica of an Ostend two mast fishing sloop some years ago. The leading shipbuilder wrote the book after the completion of the sloop 'Nele'. Both books are filled with plenty of detailed drawings.
Ground on that information I redraw the plan of the main frame an add as much as possible details.

I have made a wooden box of which the inner dimensions are the sizes of an A4 paper. The paper with the glued frame parts fits in it. On top of the wooden frame parts I glue the original frame plan and cover the hole with a plank of A4 size and lay some lead weights on it. There is space for three frames in the box. Next day I have a strongly glued piece with the frame drawing on both sides which make it easy to saw the frame and to sand the sides and the bevels with the drum sander. After being sanded, I treenail the frame.

I use the carbon copy to glue the first layer of the frame on with rubber cement. Between the joints of wood pieces I put wood glue. On that layer I lay once again a carbon paper and exactly on top the frame drawing and press trough the outline of the frame. This time the copy is made on the wooden layer.

Part 4: Making the frames
4.1
I can start to make frames. I must make thirty frames, that can take a while. The frames of a Flemish fishing vessel ware made in two layers with some eight to eleven different pieces of oak.
I will try to explain my method. Probably there will be other and better ways, but this method suits me.
I first lay a A4 format paper between two layers of carbon paper (typewriter era) in such a way that both sides of the paper touch a carbon side. Then I lay the frame drawing (also A4 format) on it and take care that the two papers are exactly on top of each other. When that is done I press trough the frame drawing with a fine embossing pen. The result is a copy of the frame drawing on both sides of the paper. -

The sternpost and the stem are consolidated on the keel with steel straps. I do not know the term in English. I make them from a plate of brass. I am not used to work with metal. I sawed the pieces with the fret saw. The stem pieces are curved and the stern pieces in a hooked shape. To obtain identical couples of straps I solder them together before filing them. After being filed they can be loosed from each other by heating the soldering.

I wait until the cut off stems become yellow (takes some months) and saw them between the knuckles into hollow pipes. The pipes can be split easily into sticks with a knife. A little tic on the knife with a hammer may help. Split the sticks further as close as possible to the needed diameter for the treenail.

I will now start an attempt to plank my hull. Planking seems to me a complicated process. I read many tutorials about the subject but it remains a bit abstract to me. Probably it will clear out while doing it. I hope that my following actions will be correct. I intend to plank my sloop completely at the port side and to keep the starboard side open from one plank below the wale on to keep the ships structure visible.
The hull will be planked with 12 layers of planks (wale included). The width of each plank varies along the length of the hull. To determine the shape of the planks, I mark the plank widths on every fourth frame. I lay a strip of paper around the curve of the frame and mark with a pencil the top level of the wale and the bottom level of the keel rabbet. With the help of a proportion diagram I divide the curve length on my paper strip in 12 parts and mark them on the frame.
