Re: Bau eines weiteren Hausboot-CAT (ECO 68)
Hello Bernd, Hello all,
Almost abandoned and snowed in is my small shipyard on the horizon of my farm. My two sheep now have winter fur ... and maybe I should get out the warm shoes ... My chickens are trying to find the last blades of grass under the snow. Moppi, my dog is having fun in the snow right now. I wish all boat-builders here in the "North" a nice hibernation ... and you in the "South" - a lot of creativity,...ciao until spring, when the sun wakes us again ... I wish all a happy new Year! best regards, Jens |
Re: KD1000 Tiago
Hi Patrick
It was not my intention to push you. The point is, everyone in this group and there are many. As you mention, for example Andrew to share there experience. This will help othewr builders to try new avenues. Or for smaller designs Hans and his "Little Tri". The idea with the garden hose as joint and so one.? Sorry Patrick, I will look at your file when my Internet is working better. Cheers Bernd |
Re: KD1000 Tiago
OK, Bernd, it is in the file section, titled ¡°Organic fittings overview.¡± I added a little on wetting out carbon and buying in bulk if possible.?
I am very much a beginner with carbon fittings, so to the rest of the group, what experiences have you had with carbon fiber fittings? What have you learned that you can share with us? It will help a lot.? Andrew, welcome to the dad club. The pictures of your chainplates helped me a ton, by the way.? Cheers Patrick |
Re: KD1000 Tiago
Hello Patrick
Thank you for your great description. It covers the main issues in an easy to understand way.? Can you pleace place this in the FILE section please. Including the drawing. Let the first part away because it covers ideas how Tiago can still go on. If I had to do it with my bad English I prever your clear description. You have not to make a new text. Put it in as DOC file or PDF it will not matter. How is the Voyager coming? Dit you find the right hydraulics? Look at VETUS the have good information. ?You can even load the mounting instruction there. Cheers Bernd |
Re: KD1000 Tiago
Hi Thiago The D.R. Voyager is our build. Good job taking the time clean up and fillet as you go. I think you will be glad you did. And remember you can probably also make your beams before you get a larger shed. And the other smaller parts like the rudders etc.? I highly recommend making your own carbon chainplates and deck cleats. And brackets for anything too, if you can make them work. There are two general methods that I have seen and used: ¡°±«²Ô¾±-»å°ù²¹±è±ð¡± This method is to clamp your pipe or tube (with plastic around it) in place on top of a plywood spacer, then drape uni carbon over the tube and down beyond the spacer in layers to build up strength. I like to wrap a little fiberglass around the pipe first. This is a good method for making chainplates and deck cleats. Bernd wrote an article for chainplates and another for deck cleats using pictures from Andrew¡¯s green 860 using this method. The article is in the files section of this forum.? ¡°Laminate and drill¡± The other method is to use a large block of wood covered in plastic as a mold and drape your carbon or glass over the block, alternating the direction of the strands, or using a combination of biax and uni. In this method you make a ¡°C¡± or ¡°L¡± bracket, cut it into the shape you want, glue it in place, then drill a hole through it. This is the method Bernd recommends for gudgeons.? And there is a blog where a guy uses this method to make a snatch block: http://maiaaboard.blogspot.com/2014/01/technical-post-carbon-fiber-snatch-block.html I used the uni-drape method for my cross beam brackets in the photos, but if I had to do it again I would have used the other method to make L brackets. I would have done this: After reinforcing the hull with extra plywood, cut a slot through the hull. Then laminate a long L ?(right angle beam) using a big block of wood as a mold. Alternate strand direction. First and last layer should be fiberglass cloth. ?Sand and carefully cut the long L into shorter pieces. Fit one piece through the slot in the hull. Fit another piece outside of the hull, butted next to the first piece. Glue them in place together, cut the flush and drill a hole through them. This is one possible way to make brackets that hold an aluminum tube. Or any kind of eye, for that matter. The bracket outside the hull is only needed for applications that force the bracket back towards the hull. Of course you could also make the slot wider and make brackets on the other side as well. Or change the angle of the bracket to align better with the load. Like a chafe-free anchor point. ? Cheers Patrick ? ? |
Re: Bau eines weiteren Hausboot-CAT (ECO 68)
Hello Jens
No time for boat building in the North. You are rigth. Huminity is one of the big problems and from many neglected. Special when you work with plywood (in your case a bit different with your material).? So a good time for the family. Thanks for your nice words. Yes, I have a lot of friends, also here in Maisons. It is a small community of only 17 inhapitants where the people care about each other. Besides a lot of Englsih friends here around. I could go to the Netherlands where I have also a lot of friends or Spain. I prever to stay here over the Christmas time. The French do not so much about Christams, so here is the place for my in this time.? So to all my christmas greetings and take care of each other. Best regards Bernd |
Re: KD1000 Tiago
Hi Patrick thanks. ? I'm working alone. After the panel is glued I jump to the cleaning process. It s far better to clean than sand.? After cleaning up the resin excess I start to do the fillets and than start the cleaning process again.? The result is an almost "free of sanding" surface.? The whole process of gluing panels takes me five hours of hard working for each panel.? The best for me is to glue one panel per day.? It probably takes a lot more time but the result is the boat's interior finished.? I hope to have answered your question.? Fair winds Thiago On Dec 13, 2017 2:00 PM, "voya12m@...

Re: KD1000 Tiago
Hi Bernd, ?thanks for your positive words.? I dont want estimate time, ?but the end of next year would be a nice date to launch ?the boat.? unfortunately i still have to find(rent) a place to assemble the two hulls together.? This probably will take more time then expected.? I'm almost accomplishing the side hull planking. Next step is to plank the chine and the keel.? I'm still studying Kevlar prices for keel lamination.? By the way I've seen the D. R voyager pics and i think the carbon fiber "parts". " not sure how it is called" very interesting thing once that you eliminate screws on the hull.? It sounds great for me cause I have the bad experience to have rotten wood on my last boat caused by screws on the plywood hull.? No matter how good is the sikaflex or whathever you use, ?sooner or later it will fail.? I see kd860(Tasmanian? the green one.? Very well built) uses the same method.? I would like to ask to the guys who built such parts if they can share the how to ? in this group?? Thanks to all On Dec 13, 2017 9:36 AM, "Bernd@... [k-designs]" <k-designs@...> wrote:

Re: Bau eines weiteren Hausboot-CAT (ECO 68)
Hello Bernd,
The temperatures and above all the very high humidity do not allow me to continue building on the ECO. I do not want to "preserve" the moisture in the plywood with Epoxi ... that's why I'm already "hibernating". It is also the time for the Christmas preparations - there is also a lot to do there. Bernd, I read about your destiny two years ago ... The community here can not replace a family, but I think in their mind they are with you at this time. Maybe you can celebrate with friends, I wish you a contemplative time, I also send sincere greetings to all the others here in the K-designs forum for the chrismastime best regards, Jens |
Re: Eco 5.5 Sailing Version
Hi Hamish Nice to hear I am a legende in Kiwi land ;-) You have time. It is already satosfactory I find, sitting on the boat and bottering around, spring is just coming so you have time. Nice to hear I am a legend in Kiwi land ;-) You have time. Is already satisfying I find sitting on the boat and bottering around, spring is just coming so you have time. Every throught on Christmas is a smack in my face. Christmas 2 years ago my wife died. Never mind. Merry Christamas to you and all K-designers Bernd Von: "carr.hamish@...

Hi Bernd, thanks for the encouragement. No I have not been sailing yet, I will post images and comments just as soon as I do though. Great to hear the yacht has created interest on the Duckworks Site. I was in buying supplies for the yacht a couple of weeks ago and got chatting to the store attendant, he was intrigued by what I was doing and as soon as I showed him an image of the design he recognised what it was and who the designer was. You are a legend! (Kiwi slang for all round good guy!) Merry Christmas Hamish?

Re: Leeboards
Hello Primozz
Thank you for your explanation how you handle the boards. By the way, instead of Teflon I reccoment on the drawing a coat of Epoxy/Grafit/silica. Same effect as Teflon. I propose to us the luffboard for load reasons on the bearing and lower daggerboard part + guide. It is a question of praticing. All the theoretic stuff helps nothing, you have to do and experience it. I am not so keen on holding the boards down with elastic, because the load can be highers as the elastic allows or be to strong in the case of grounding the do not rise. It is a question of playing with the system. Debries can be easy removed, you can have it on all appendages which are lower as the hulls (rudders, fixed keels a real dagger board which you have to rise (more worse) etc). A spash of water on the daggerboard case you will not feel or the boat speed would be measurable different. In theory always a pro and con can be found. So in the end lets use the system and go sailing. Then you get automatic the answers. And as last remark, have you ever cleaned and re-painted a center or dagger board box after the boat was a saison it the water? So, this was my final remark to this thema.? Anybody building, special down under, sailing done? or others nice small or big things done?? Cheers (sh..t need a new bottle of Wodka) Bernd ? |

Re: Leeboards
Hi Howard, David usually i kept both boards down going up-wind and one down on half-wind course. Usually did not do the effort to lower/raise after each tack. The rubber band was fixed, pulling the board down. I newer released that one except for the winter storage. For raising the board there was a 1:2 block. . . . . yes you are right - the pivot-base draged in the water sometimes. With picking up some debris i did not have issues, maybe also because the water is quite clean where i sail. I rarely had the case to pickup smth either with the rudders or outboard.
