The epoxy will add about 16 000 kilo strenght. Every square centimeter of Divinycell have a tension strenght of 22 kilos, the bulkhead is 3 cm thick the periferic is about 200- 300 cm.
Mulitply it gives aboaut 16 000 kilos.
That makes it worth injecting e...
Everything went fine but there was a bit of panik when the epoxy started to overflow. I should have known better. This is what I learnt. The outgoing hose should end higher up than the ingoing. A child could have figured that out. now I know for the next b...
I have injected epoxy to the edges for the bulkheads since 2009 I think. I have experimented with different methods refining my technique. This way is the best so far. There is a short time window to do it before the epoxy sets. To speed it up I mixed and ...
Doing hatches one have to consider the size of the person passing through. That I my weight will not ballon out of control I have come up with the
YRVINDS CONSTANT WEIGHT DIET
The word diet comes from old French, from Latin diaeta, way of living, diet, fr...
Today I have laminated the rim of the door on the aft bulkhead. It consist of 4 layers 600 gram carbon about 10 meter along the perifirique. It went well but took a long time.
For more information on my project see Yrvind.com. There you can also donate on ...
By laminating the inside I have now connected the inside and the outside laminate having the Divinycell core in the middle this creates a strong rigid and light hatch.

Lucky again. The cover fits very nicely over the coaming. Also about my idea of gasket. Gaskets deteriorate over time. By definition a cruising boat is meant to be away from ship yards often in a desolate location. There it is not easy to change a gasket. ...
Today 3 girls from the Filmschol in Gamleby have been here to interviuw me. I took the opportunity to ask them to film this video. They also tried to teach me a bit about imovie. I am rather thick headed so it will take some time. They live not far away an...
The new maskin is a kind of disk sander. The first one I bought about 30 years ago at a time when my economy was much better when I still gained money from talks and books. I was in Värnamo to buy a bandsaw from EJCA.
The salesman suggested I also buy a d...
Today I have mainly been slowly working to get the rim of the hatch even. I have measured and decided to cut 10 mm of. Then I scribed it and cut it with my jigsaw using a carbon abrasive blad. Important is if you err, err outwards otherwise there will be a...
Today I again try to explain why I do not make the bulkhead hatches so they can close from the inside. It is a complication, I like to keep things simple. Some people say that will be good if the hull gets penetrated. But in my world the hull of Exlex will...
Here is the mattras. Now when I see it in place it seams much to big. But it is a balance. Alone at sea it can be less. Exlex 2020 had 70 cm wide and 185 cm long. In port it is nice to have more space.
Bris bunk was 110 cm wide.
Aluminum Bris 120 cm wide
...
On the side of the bed there is storage. But below the bed there is 20 cm storage for water on the side of the bed there is side lockers about 40 cm over the mattras the are 7 cm thick. So the bottom of the side storage is 67 cm below. A 67 cm deep locker ...
In sandwich constructions it is important to have spacers at point loads. The eye bolts create point loads. That load have to be spread out over a larger area. With the help of backing plates and spacers that is done.
Spacers can also be made by remowing ...
Borka the ishockey player helped me to do film today. He was better at isheckey. In the film I work very very slow. Luckily I am faster in real.
I shown textile handle and a few other things. I may do more tomorrow but then there will be no one there to fi...
Yesterday was boringly slow. Now I hope to make more clear. The lid is tested. When I filled with fluid water it dripped. I was sad but soon I found the culprit I was the handle. Somehow it seeped through there. I was happy again.
I wound some 6 mm polyest...
The aft bulkhead is now in place. It is a good place and it is comfortable to pass through the opening. The bench in the dining room is 60 cm wide 5 cm more than Exlex 2020 at that was 55 cm wide. This makes it more easy to swing around, mowing my legs 180...
A double ender is smaller than a transom boat for the same lenght.
There is not so much space on the aft deck.
On the other hand a double ender have a longer waterline than a transom boat for the same lenght.
A double ender can better take waves from behin...
I have now plotted the measurment from the mold to the Divinycell and covered both sides with one layer of 450 gram 45°X45° glass fibre

Last might in those magical times between wakefulness and sleep I got a new idea for the lids to the lockers. The previus idea made use of 4 strings for each lid. 2 permanent for hinges and 2 to open and closeThe went up on the inside. Still I like to make...
The new idea for the locker idea turned out to be good, but more development will make it even better. I therefore started with a new mock up.
Mock up are a good teacher and mock up teaches me much.
I like to reduce the play a bit. I will also make the lid...
The video is shaky and unclear. But here it is.
I was not content with the lid for the stovage. I am now working on a third version. Lid 8 cm wide 5 mm thick made of Tufnol fastened with two M6 countersunk screws.
To see how strong it was I took a 5 cm str...
Again a new idea for the locker lid.
This one the lid is screwed with two countersunk M6 stainless A4 screws, the nut is bronze as to make it not to size. I will also put on some lanolin grease for good measure.
For more information see Yrvind.com. There y...
Now I can compare the three different hatch lids.
These hatches are not often used. It is important that they give a smooth surface..
The favorite is locked with two countersunk M6 Torx screws. I will use screw down lids for the lockers under the mattras. ...
I was pretty sure that the screw solution was the one to chose. However I woke up in the night with one more idea. Hopefully tomorrow I will know if it works.
Sure it is best to do without the screwdriver, but if I can keep track and handle an eating spoo...
This new idea I am satisfied with.
The 8 mm polyester rope partly saturated with NM-epoxy makes a very strong rod. The non saturated part is a rope flexible that can bends to go below the deck. The rope in the carbon reinfrced PVC tube behaves like hydroli...
I am very pleased with the results of the latest idea. It is very simple to produce compared to the other ones. Just a grove done by the router to accomendate the pvc pipe and the carbon reinforcement.
To cut it out I just angle the blade of the jigsaw at ...
I thank everyone for the suggestions regarding the locker lids. It is good to have people watching over what I do to Exlex the canoe yawl. That way she can feel she gets good handling.
Now I turn my attention to the partial bulkhead between the dining room...
Now after experimenting with the locker lids I start with the dining room. Unfortunately 20 cm is missing of the Divinycell. Usulally the pieces are longer like 240 cm H 80 But here I am using H 200 that is 200 kilo per cubic meter. Reason is there is goin...
Hi friends. Here is Yrvinds constant weight method.
Many people decide on this first day of the new year on a good thing.
Modern life have made us to live a unhealthy life. Gouvernment have told us to eat carbo and many times. Shopping have made us consume...
Working in the dining room with the water containers. The mock up had 60 liters there and 60 liters under the bed. Somehow I thought I get more place in the dining room with 45 liters. I continued to work. The sleep between Dec 30 and Dec 31 got interupted...
I got a new idea. This video will try to explain but maybee it is not clear so go to my website Yrvind.com where there is a text that may make it more clear.
However. I came uo with a new rig more easy to reduce sail area with. Also the voyage would be mor...
The fillets on both sides of the middle and the aft bulkhead is done. I prepare for the injuction of the NM-epoxy.
last time I made a shameful mistake. The incoming hose was higher than the outgoing. The confused thinking was that I would see the epoxy com...
As the the Ljungström mast of the rig can be rotated it can increase efficiency of the sail by greartly reduce the turbulence on the suction side of the sail. As most of the lift comes from the suction side the efficiency is much increased.
The Laser mast...
Now the two aft bulkheads are injected. It went very well. With the longer hose for the rising epoxy laws of nature guaranties no overflow.

Small structures small problems. The mast are about 3.5 meter above deck and carry 3.5 square meter sail. Not more than an Optimist dingy. Exlex the canoe cruiser have much more stability and her intended route will take her into much windier waters. Still...
