一艘小船建造



In2006 I bought these four volumes of ?fjordsb?ten og Nordlandsb?ten. Reading them with extreme interest over and over again, trying to learn all the difficult words and expressions. Slowly I realized that I had to try to build a boat like that.

During fall 2008 I came across a pine with a root that seemed to be suitable for “lott”, the piece between the keel and the stem/stern. I cut it down and managed to get two “lott” which consists of part of the trunk and a bit of the root. The trunk above I cut to a keel stock.

I let the three pieces air-dry for two years to see if they cracked, and they did. The keel stock was full of diagonal cracks and was degraded to firewood. The two “lott” cracked only a bit on the surface. After processing there were no sign of the cracks.
With the important stock in place, I decided to build the boat I found a quite detailed drawing of, in volume 3.
First I made a full scale drawing of the keel, lott and stem/stern. From the drawing I made templates of the two lott and stem/stern. Then I started to process the wood. I bought a new stock for the keel from a sawmill. Also this stock had some cracks, but most of them disappeared during processing.

that’s the price and it is normal in Norway for books like these. Unfortunately I don’thave good pictures of the keel shape, however, the pictures uploaded became smaller than expected because of the way I did it. I think I by now have found out why, so for next post it will be better, hopefully. Biggest size allowed is 500x500 pixels on this forum. For the wave shaped keel and lott I have tried to enlarge part of a picture I have. My be you can imagine how it is like

This is the cross-section of the keel. The picture is from the book.

The name of the boards is slightly different for ?fjordsb?ten and Nordlansb?ten. I will use the Norwegian names. The names are from the books.

Halsene are made from stock 5/4" x 6 1/2". This picture shows two halser clamped together after the profile has been shaped.

One hals partly shaped using an axe. Removing wood from the top to the middle of the plank, than it is turned over and the same is processed again. There after a planer is used and finally sanded.

Halsene are tested on the boat. The slightly twisted shape is visible on the one closest to the camera.

Two halser are soon ready for attaching to keel and lott. The two three-fold cotton threads are "glued" to the boards using lacquer. The nails only keep the threads in the right place during the gluing process, and is removed prior to attaching. This is the way I did it on this boat. I am not sure it is a good idea, and will probably not use it on my next project.

All four halsene are completed. The top edge is shaped after all are fixed.

Looking from the front, it looks like it from the stem turns down a bit and then rises at the middle an then going down again and up at the stern (the latter one you can't see). This is what you see from this angle, but the real thing is that the middle part is the lowest part.

Another picture. The middle part is wider and looks as it is rised. The upper edge of halsene is more or less parallel to the floor. I checked by measuring the height above floor at several points. Look at the upper edge close to the camera. It looks like a straight line, and that is how it should be to make the shape of the next board right. I will come back to this later when I post pictures of the rem board.

To shape halsene correctly is a bit of a challenge. As far as I know, no living person today know how it was done traditionally. Some enthusiasts have found out that it should be done approximately the way I did, but there may be different opinion about that. I used the opportunity to do some experiments and made totally 20 halser. Finally I used hals no. 16, 18, 19 and 20.Here is a picture of the 16 I didn't use:
