17112011(Turn over and beer)

Vaughn the magnificent have had us this Monday. We glued up sheer strakes and skegs at the end. Brass nailing seemed quite hard without using dolly. Stem, my task, hasn’t emerged yet, because it is under the planks that I would planed off later. My long board glued last Wednesday looked okay. I reused a piece of off-cut which is 12 mm plywood. One achievement we got today is that we figured out how to push the planks against the temporary frames. We started to talk about that with using long piece of woods nailed on the temporary frames and sort of complicated method but we found out quite an easy and neat way to push them, it doesn’t hurt the planks as well. First, nailed a long piece of wood firmly onto the frames and make a groove at the end of each piece to hold another piece of wood for pushing wedges against the planks. EZY. After, arrange them the only thing to do is pushing until the glue comes out. We used only 3 cramps to hold sheer strakes.


The method we found worked well checking next morning. Starting with sanding the glue off, I kept doing the stem. Planing the glue off is much harder than planing the wood. We used glue enough to fill the gap between here and there, but it was too much somewhere so that planing was quite hard. To make gunnels, Chris showed us a jig for them and how it worked. Buzzer, table saw and thicknesser were used. To make the skegs round, we used router. There are a couple of gaps on the planks which are usually between two planks at the edge of faying surface. Chris showed us how to fill them up without any messiness with using masking tape driving both sides of the edge, glueing and taking the tape off. Simple. Stem is getting its shape with taking off the glue and planks covered on it. Prior to glueing the gunnels, we decided to have them into steam machine, because they were too stiff to put directly on the sheer strakes. It took about 1.5 hour to boil the water and 15 minutes to steam the gunnels 15 minutes to be cool down for taking a shape. Before doing the steaming, we measured how round it is, checking the heights from both ends to the bottom. So many cramps were used for holding the gunnels on the planks. We made small bits of wood to protect and to hold the gunnel firmly. Anyway, we have to keep thinking about how to protect the boats and how to work easier and more proper.

One thing happened on Wednesday morning was the skid was 7mm off to the centre line. Forward part was okay but it shifted aftwards. We were told that we can learn by making mistakes. I thought that it wouldn’t really effect on the stability or the maneuverability of the boat but for the future we have to think about what was the mistake and how to solve it. Think before I do. Think while I do. Think after I have done. I should have taken a picture written on a white board by Chris. Anyway we have to take the skid off by sawing with two flat thin sheets of wood for protecting the boat rather than using a grinder. It was felt like a punishment or things like that. Otherwise, we could turn over the boat that morning. It took for whole morning to take the skid off, sanded the glue on the bottom, chiseled, made another skid again and fit it. By the way, Jibreal brought some doughnuts for us from a bakery which one of his friends set up. It was delicious. Stem is looking good so far. Anyway, we turned over Moira’s dory, but before that we had sweep stake for guessing the weight of the boat. I guessed 30kg and bet 1 dollar but it was 31.5 or something. Actually, a temporary frame for station 3 was stuck with the boat and it took a while for taking it off. We used wedges and a hammer. Additionally, I made a handle for my long board. I used off-cuts for making it three pieces and assembled it with glueing each other. We had a time with boat owner’s husband who is Chris, my teacher, to hear about the concept that normally he is going to use it for fishing. He told us about thwarts, risers, quarter knees and bulkhead. After the class, Chris and us went to Carrington and had beer. I told him about what I did last vacation and what I am going to do in the future. It was really good time, the weather was even good as well. Choice!
