  2. Apologies to Keith, we shouldn't really high-jack his building log ... Thanks for your appreciation, I'll do my best. Well, due to the scarcity of resources the Inuit had to be opportunistic in the use of materials. Bone was used for certain parts regularly, such as toggles and certain high-strength or wear pieces (say sheathing underneath the bow and keel to protect it from the ice). I think whale-ribs were also used in kayak construction, but wood was prefered, as it could be more easily shaped to suit the users needs - kayak were 'made to the measure' of its owner. In several works it is described how a master-kayakbuilder would chew the wood of the ribs in order to allow it to be bent into shape ... ! I have put together a bibliography on skin-boats some time ago, which you can download here: https://www.maritima-et-mechanika.org/Marine-Forum/Skin-Boat-Bibliography-190911.pdf Probably the most useful reference is Chapelle's part on skin-boats in ADNEY & CHAPELLE (1964). Back to the GERMANIA now ...
  3. Thanks Keith. Good to see the internal structure. Most museums exhibit usually complete boats. The Inuit not only used driftwood, but also began to trade-in sawn timber from European whalers, when these began to appear on the Greenland coasts in the later 17th century. Whether they obtained sawn timber from the Viking communities until the regular connections with Norway died away in the 13th century and whether this may have influenced their building techniques is not known. However, contacts between Inuit and the Viking communities resp. their descendants seem to have been generally hostile.
  4. Well, the reason Trump went for it are the mineral resources ... one of my activities in the arctic institute was to help develop mineral resources in a sustainable and socially responsible way. In the wake of my work in that institute, I got quite interested in the traditional kayaks and collected a good number of printed resources on them. At some point our institute was presented with a kayak, but it wasn't terribly original anymore. Together with a number of colleagues I developed a course for a master degree in 'arctic studies', aiming to train students inter alia in sustainable management of resources and cultural awareness. We had a series of 'bonus' classes and I put together a lecture on the various types of boats used in arctic waters, including kayaks, umiaks, and others. So, if you have some kayak pictures, I would be interested ... Ah, and yes, I am looking forward to your progress on the GERMANIA !
  5. We have the tendency to pull all standing rigging taught, which in fact is only partially correct. Although in real life, the rigging would have been pulled taught, the weight of the material would pull it into a catenary, which is quite visible on photographs. This is not so easy to reproduce without looking untidy. I would also consider the relative humidity during the conditions under which you are building. High humidity tends to tighten rigging made from natural fibres due to water uptake and swelling (which is counter-intuitive), while lower humidity tends to slacken it. You account for this in order to not have surprises during different seasons of the year, if these entail large humidity variations.
  6. The Greenlanders must have been really offended - considering that they managed only a few years ago to achieve a relative independence from Denmark (which continues to subsidize them). Worked for some years in a French arctic research institute and had a number of students from Greenland. Nice guys mostly. Never managed to get to Greenland myself unfortunately ...
  7. I have used soldering-tin, spiralling thin copper-wire around it, to represent re-enforced suction hoses and I recently saw another example in this building-thread: https://modelshipworld.com/topic/20162-new-england-stonington-dragger-by-friedclams-148-pob-a-1920s-western-rig/?do=findComment&comment=653110
  8. Not sure, a clear PVC-hose would be contemporary. A black or red rubber-hose might be more appropriate. One can nicely simulate such hoses with soldering tin-wire. It can be painted or blackened with a suitable blackening agent.
  9. This is neither 'my' period nor 'my' region, so I overlooked this build-log until now - shame on me ! It's an excellent tour-de-force on weathering. I will keep watching the progress now ... On the subject of lamp-boards for the navigation lights: I seem to remember that in the mid 1970s or so the maritime rules were changed, requiring the boards to be black rather than in red resp. green. Anyway, roundabout that time I noticed the change. There are some guys in the model railway fraternity that push the naturalism to its limits. There is, for instance, this Swiss, Marcel Ackle: http://www.feldbahn-modellbau.ch/. Quite inspirational !
  10. BTW, most of these Heller-kits seem to be based on plans issued by the Association des Amis du Musée de la Marine in Paris, which in turn are based on drawings from Pâris' 'Souvenirs de la Marine'.
  11. I have been using glue-sticks (Pritt, Uhu, etc.) on wood, metal and acrylics. Good for small parts, as the application is not messy. Photo mounting spray cement and similar have to be used in well-ventilated rooms and you have to protect the work surface from over-spray. Not really worth the effort, if you deal with drawings smaller than say A5. For larger drawings, the glue-stick dries too fast and you would have to apply it in stages, which may lead to distortions. Here, the mounting spray may be better. One should have a flat-bed ink-jet printer with a height-adjustable nozzle to be able to print directly onto the wood etc. of different thickness ... ... thinking about this, if you have a suitably sized, but weak laser-engraver, you can burn the lines and then cut the piece out with the scroll- or band-saw.
  12. I found the Danish Veevus (http://veevus.com/) the best and they have a good range of colours and sizes. For seizings you may also use the monofiliment, which is the finest 'thread' (it is a wire, strictly speaking) I am aware of - but it only comes in black and translucent. Check out ebay for offers.
  13. Johann, in his log on the CREOLE, has shown a simple leather-splitter, kind of an inverse plane. Seems to work well for him for 1:48 scale stuff. I cemented (with superglue) 20 mm sections of 0.4 mm copper wire onto a flat milling sub-table and turned it into 0.2 x 0.4 half-round stuff. The principle has been used by watchmakers for the last 150 years or so, employing what they called wax-chucks (the 'wax' was actually shellac), that is a small face-plate. What is obviously important is that the rod/wire is absolutely flat and perpendicular to the Z-axis of the mill. I would mill the groove and then leave the wood in situ for cementing the rod on.
  14. I learned that later (when I saw it on your LOGBUCH articles), I thought you would be living in Amsterdam.

About the NRG

If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.

The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.

The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
