  1. If someone gave me one of those Sixis or Aciera (watchmaker?)-machines, then I`d put it in a sealed showcase to protect it from dust and humidity, I wouldn`t dare to touch it without wearing cotton gloves. If I did any damage to such a machine while operating it, then I`d have seven sleepless nights in sequence. I think that one shouldn`t recommend these swiss precision tools to a beginner. Michael
  2. Vaddoc I`d plank the hull entirely before to apply force to the stem post. The assembly of molds, keel and stem looks too fragile to me to do any machining on the stem post at present state. I`d glue the planks to the molds and stem one by one rather than to attach them all with screws temporarily. A glued or welded structure is more rigid than a screwed, riveted or nailed one is. If the stem post is tapered prior to sanding or scraping the hull smooth, then minor scratches on the planks won`t do any harm. That`s my opinion. I may be right or wrong. Michael
  3. Ron If you want to run the drum sander at high rpm with low vibration, then you have to balance the drum, I suppose. There should be equal distribution of mass around the longitudinal axis. See balancing vehicle`s wheels. The drum should be balanced with abrasive paper mounted, like a wheel is balanced with tire mounted. Nonetheless I like your simple design that you can modify according to your needs. What about a conveyor belt to ensure constant feed of material to be sanded? Michael
  4. Point, I just found a link to a free nesting soft on a german forum for cnc-machining. https://deepnest.io Yet I havn`t installed and evaluated it. I read the brief description, only. I think it`ll do the job. I don`t know whether parts are rotated during nesting or maintain their original orientation. Rotating them may not be desirable because it changes the run of wood grain.

  5. Eberhard I think that hyw - unfortunately he didn`t tell us his name - built the winch strictly according to the drawing released by ANCRE. So there`s got to be a different way to lock the gears to prevent the winch from spinning reverse. A gear that`s shaped like a circular saw blade with a pawl, that engages at the steep side of rhe teeth, is self-locking indeed. But I think that self-locking of the winch on this particular ship is obtained in a different way. Moving the long two-sided lever seems to spin the winch. Perhaps friction prevents it from spinning reverse.
  6. Hi Spyglass I ran into similar trouble when I sanded a hull. There`s a remedy, that works fine. It`s two layers of cardboard laminated to the inside of the hull with pva. Note the variation of plank thickness along it`s way. Even in those areas, where the sheer strake has half of it`s original thickness, only, it`s sufficiently rigid. I applied pva glue to the cardboard abundandly. When being attached to the hull the excessive glue fills the gaps between the planks and provides contact on the entire surface. The cardboard was pressed firmly against the plank
  7. Hello Carl What about domestic cheese like edamer and gouda. don`t they contain enough gas bubbles? We should return to the original topic, I think. And I think, that you`re the one, who lives closest to my home town. I live some 20 km south of the place, where the rhine divides to waal and oude rhin. Maar ik spreek geen nederlands. Michael
  8. Hi Tony You got to divide the hull surface into longitudinal sections, first. They represent the plank strakes. Each strake is a sub-surface on it`s own. Then you apply the develop or flatten command in your CAD application. This command doesn`t just project the selected entity on a plane. Rather than that it straightens the entity. Be aware, that the thickness has to be taken into account. By default surfaces don`t have thickness in virtual modeling. The development command may only work, if the surfaces (plank strakes) are straight or flat across their length. So the station
  9. Hi Ben Your second approach to lofting the hull seems to be the right one. Now you have a single surface. Before it looked like a "pile of patches". There`s no bad intentions in telling you that. Does fusion 360 have analysis tools other than zebra striping? Can you apply gaussian curvature to the hull? It shows the amount of curvature all over the surface in colours. It shows the direction of curvature, too. Inward or outward. Is there a tool called curvature graph in fusion? It`s a set of "needles", that point perpendicular to a curve or surface. Or rectang
  10. Tony, I wondered whether you installed the rear hoisting beam, too. In post #55 I found the answer. You work pretty fast and the things you do look good. I think, you machined the brass parts flawlessly. I cross my fingers for the surgery and your recovery. Don`t let us wait too long to follow your "tutorial" again. Indeed you explained the essential steps of the build in detail. A guideline for everyone, who intends to build the same or a similar boat. About piercing the hull. It`s the projection of an object on a surface. Whenever the object, that pierces a surface,
  11. Yet I haven`t built the chaloupe armee. I bought the folder years ago at the annual modeler`s fair in Dortmund. I thought it was a tiny boat and tiny things are quite easy to build. Then I took a close look at each drawing and the manual. It seemed to be too tricky for a beginner like me. I do remember lots of details that made me decide not to build this one as the first model. Currently I´m building "Glad Tidings" by Model Expo. It`s big enough for the clumsy hands of a bricklayer. I don`t dare to start a build log. Let`s see whether and how it grows, first. I noticed few imperfections
  12. Tony, I noticed that the hoisting beams of your chaloupe are inserted into it`s hull. In Mr. Dealcroix`s drawings those beams pearce the hull. How come that you deviated from the genuine design? I just wonder. The longer I follow your build log, the more I believe that you`ll succeed. Michael
