  1. I am surprised that they are allowed to sell this still. I thought stools/chairs with three or four casters don't get a CE certificat anymore due to the risk of them tipping over and rolling away under your butt ... chairs have to have five casters these days.
  2. Sounds like a good solution! I was indeed wondering, how you would deal with this area of the hull ...
  3. Some people, including myself, use hypodermic needles as marlinspikes for making false splices miniature rope. One has to blunt the edges a bit - they are obviously very sharp and meant to cut, but you don't want to cut your rope. You twist the rope a bit so that it splits and then you push the 'marlinspike' through. Now you can feed the free end into the needle and slowly pull it out with the rope inside - repeat and you will end up with a reasonable splice. As I had a nice ebony handle lying around (which may have come from some antique medical instrument from my fathers estate), I made a brass ferrule for it and cemented a hypodermic needle into it. I think it was a 20G (yellow). For serving, I would try to get hold of some 16/0 fly-tying thread, which is not fuzzy. Indeed, serving without some 'helping hands' is difficult. I tend to use half-hitches, rather than just winding the thread around. Each turn in this way can be set and does not come loose. Of course, having/building a serving machine would be the next step up ...
  4. I gather there various constructional and hydrodyamic factors play together. Modern freight carriers have a much higher L/B-ratio than these rowing boats. A long parallel midship section is not detrimental to water resistance, but rather encourages laminar flow. If you did cut out that part and stuck together the bow and stern sections, the overall shape would not be so dissimilar to that of the boats of old. One can only speculate how clinker building developed and Greenhill believes that it originates in expanding dugouts by adding planks while at the same time the dugout mutes into a sort of hollow bottom plank, eventually becoming the keel. This lends itself to smooth curves in (shell-first) planking with large radii. There is strength in flexibility in this construction as we know from experimental replicas. It is only with plank-on-frame construction that tight bends are possible, leading to a rigid skeleton with a shell around it (certain Dutch vernacular boats are probably the most extreme examples in that respect).
  5. Talking about launch parties: I always found it quite daring to be on a ship the runs down the launch-way, particularly, when it is a side-launch. The risk of capsizing is definitely there.
  6. Talking about memories, I seem to remember a whole room being dedicated in the NMM in Greenwich to the Sutton Hoo find, where they showed a section of the boat in 1:1 of what it looked like after excavation: basically there were the imprints from the planks long gone and the remains of the iron rivets. I gather if several 'old codgers' get onto the same project that cuts down construction time compared to a single beavering away in his own workshop. Preparation and fitting times for planks are not so much different whether it's 1:1 or a model.
  7. Another source for extremely thin, long-fibre 'Japan'-paper are supply shops for art- and book-restorers. This paper is used to 'invisibly' double up ripped or damaged book pages and works of art. I got one that has only has 8 g/sqm. For extremely fine woven fabrics serigraphy (screen-printing) supply shops are also an interesting source.
  8. I use a standard lifting office-chair with armrests. The inclination of the backrest can be also set. It was given to me for free as an office surplus.
  9. Somehow I haven't been aware of this project, thanks! One process that seems to be not so in line with how they did it in the old days is the use of templates. OK, they try to replicate an existing ship. In those old days they probably strung a cord from bow to stern and used this as reference to ensure that the boat turned out symmetrical, but otherwise everything would have been shaped by eye, I think.
  10. Under the right light conditions and with the right background, this could look almost like the real thing 👍🏻
  11. Perhaps it's not design, but just how it came out ... they needed an outlet or inlet and the place was dictated by the interior arrangements. And/or it was too much trouble to remove an old feature ...
  12. I have both, single and double roller filing guides (or 'rests' as the watchmakers call it), but never really understood the value of a single roller guide ...
  13. ... absolutely and if you are myopic in addition, this multiplies the magnification you get out of your myopia, when you take off your normal glasses. For years I got the 3x magnification by just replacing my normal glasses with plain safety-glasses. Now I need the additional magnification of reading glasses 😢
