Could you post pictures of these machines to better understand what you are talking about?

Very nice ship's capentry job ! Although on a real boat it would be a lot more physical labour to cut the rabbets, laying out in 1:1 is a lot easier than at a small scale (how do I know this ...).

Makes sense! Thinking about it, it would be also more stable during pushing, as there is less of a cantilever on the rig, than if it was pushed the other way around. I also didn't realise that there was a 'bow' end.

... equally interesting is the vertically boilered shunter on the photograph. Will you be building one too?

Would the pile-driver actually pushed from the side of the rig? I would have expected the tug to be tied up to the other side, also so that the driver can be manoeuvred into position.

We don't anything else, but quality 👍🏻

There have been five auctions since, the last one a few days ago: https://www.premiermachineryauctions.com/auctions/detail/bw134676, and more to come ... Not junk at all, but a lot of most desirable precision machines and associated tooling. The guy most have spent a small fortune on auctions etc. Some of the machines are in quality state rarely seen on ebay & Co. or dedicated machine tool sites. It's a pity that I am on the other side of the Great Lake and have not space anyway 🙄 Didn't we have a thread on this already?

Slikspan is the way to go. The sails look very good!

OK, this is now a bit of thread drift, but would concern the 'input' side of the grain-elevator. Since around the middle of the 19th century threshing was typically done by contractors, who would travel around the country with their portable steam-engines or their agricultural steam-engines and the the threshing machine in tow. This was, of course, before the days of combine-harvesters. The threshing system could be set-up either on the field or on the farm, depending on when the contractor would arrive in late summer/autumn. The grain would be collected in bags and stored on the farm, or directly transported to the mill (if it had the capacity) or to the station/harbour for shipping. However, I think in Europe grain was mainly locally milled and the flour shipped, but distances were comparatively short. Over longer distances, the grain would be shipped in bulk and milled at the destination. So, bags were used along the way from the field to the point of bulk shipping. From the early 20th century on, even smaller farms may have had their own small threshing machine and a portable hit-n-miss or similar petrol engine to drive it. Or such equipment was shared across the village. The arrival of the combine-harvester seems to have changed this pattern, as they either off-loaded into a lorry dring alongside or were periodically emptied into open lorries that then drove to mill or the shipping point.

Well, good for those out in the Far West, who have the space for such scenic settings. We humble urban dwellers have to make do with dioramas or scenes in glass boxes 😞 Where did the power for the grain-elevator come from? Manual labour? In windmills power is taken off the 'main shaft' to drive a winch with which the sacks were lifted to the highest level from which they migrated by gravity through the processing. How would be the grain delivered to the silo, in sacks or loose? Threshing machines in Europe were designed to output into sacks. Perhaps the ramp served both, the hay-barn and the grain-silo. With the carts going half-way up, this would save a lot of labour/energy. The carts would then be unloades somewhere inside the building. Ventilation doors were also my first thought, to prevent dust explosions and to make also the working atmosphere in this enclosed space a bit more comfortable.

Their full range for the German market can be looked up here: https://www.vallejo-farben.de/ In the Model Air range they have glossy, satin, and matt varnishes. I think they are also available in larger containers than the usual little bottles. There is nothing to prevent you to use these varnishes pre-diluted for the airbrush with a normal soft brush, I do this quite frequently. I found that the surface sheen is somewhat different depending on whether you use the airbrush or a normal painbrush. If you have the choice, you may need to experiment to the sheen you want.

I remember reading the research thread, but somehow missed until now the building log. I am interested in everything that happened on the Seine, after all it flows past in sight from where I live. However, judging from the background on the photographs, I think Santos Dumont must have run his trials on the Bassin d'Argenteuil, a quiet lake-like stretch of the river between two barrages a few kilometres downstream from me. Coming back to the construction material: I also would think that steel-tubes as in bicycles were used. Aluminium tubes would have been extremely expensive at that time, if at all available. There was no welding technique at that time that would have not drawn the temper from the steel-tubes. So, I think they were silver-soldered, as is the practice for steel bicycle frames.

Only chanced upon this new project right now! I admire your tenacy in such difficult times 👍🏻

My comments about coiling were actually not 'assumptions', but that is what happens to me, when I coil rope. Of course, it is also a question of the thickness of the rope relative to your arm movements when coiling. I regularly use this lacquer/varnish and acetone method on models spray-painted with acrylics and did not experience any problems. Of course, when you create puddles of acetone and let it standing there, that may soften the paint. The point is to just brush enough onto the rope to soften it. It will evaporate in a few moments afterwards.

Not sure, why people continue using diluted white glue to stiffen ropes, perhaps because it is handy on most workdesks ... If you use a fast-drying organic-solvent based lacquer (zapon lacquer or old-fashioned nail-varnish, not the modern acrylic ones), you can soften the lacquer easily with a drop of acetone. That also takes care of any flash produced during the original stiffening. And, why did you make the coils elongated, any particular reason? Naturally, as the rope has the same stiffness all along its length, it would coil up in more or less round coils. Of course, one can pull the coils long afterwards, but this would be extra work. Otherwise, I would echo the comments of the others, that it continues to be an impressively well-done project 👍🏻

Actually, you did a pretty realistic painting and weathering job, I think 👍🏻 I discovered 'dry-brushing' (as it is called now) for myself some 50+ years ago in my teenage plastic-model building days and it is a very useful technique. Also, using lead- or coloured (mainly white) pencils are very useful to put highlights onto edges or raised parts, enhancing their three-dimensionality.

Thanks for the 'thumbs up' ! ***************************** Installing the wales It was fortunate that the upper edge of the wale was marked in the original drawings. I had transferred this to the bulkheads and cut appropriate notches. Somehow, however, these notches turned out to be not very useful as I would have to score the whole core of the hull accordingly, which would have been messy. In the end, I ignored them, though used their upper edge as guidance for placing the wales. I have no information on their dimension, but thought that a width of 240 mm = 1.5 mm looked about right on the hull. They would have been probably composed of two thick planks. For the thickness I choose 0.75 mm, as the hull-planking will be 0.5 mm thick. Contemporary pictures and naval construction books show both options, smooth hulls, where the thicker wales are not visible and step-changes in thickness. I think smooth hulls became fashionable around the middle of the 19th century, but in the Baltic they were always lagging a bit behind, so I went for the stepped design. Perhaps this is a problem of building up the planking around a solid core, but the way how the wales run against the gilling at the stern caused me some head-scratching. The point where the upper edge of the wale touches the gilling is marked in the original drawings, but it is not clear, where the lower edge touches it. While the wales have an easy run all along the ship, at this point some twisting is needed. I had not done any planking with styrene before. It turned out to be quite simple: unlike wood, it does not have grain of course and strips can be easily bent and twisted even across the long sides. Pulling the strips around a round piece of e.g. steel causes the strips to curl and one can thus achieve a nice pre-bending without the need of much clamping force, when cementing them on. Nevertheless, the wales were attached with the recently discovered artificial nail cement, that is a mixture of light-curing acrylic cement and cyanoacrylate. It sets fast, but not so fast that no adjustment would be possible. I let it seep under the wales attached to the hull with Sellotape. Hereby I worked from the more complicated stern forward in more or less long sections, depending on the curvature. Final clean-up will be done, once the rest of the planking has gone onto the full, with the view to blend everything nicely together. To be continued ...

I thought this was a fairly common tactic at the time (and probably still is, using modern boat-types and propulstion systems) to attack anchored ships off-shore. Such small boats at that time wouldn't have been able to keep up with moving warships. With today's speedboats the situation is different, as the pirate-attacks in various waters show.

Never seen before such low bollards. I gather only a single loop/eye of wire-rope goes onto them, right?

So no condenser fitted? Or a boiler feedwater pre-heater? Do the steam-pipes get some insulation? I could imagine, that in winter one would get a lot of loss of pressure and condensation.

Thank you very much for the kind comments and the 'likes' ! ************************************************************* Digression 3 As the start of the planking is imminent, I had to think about a way to shape thin, narrow and long strips of styrene. A clamp is needed that can hold strips down to 1 mm width, 0.25 mm thickness and 150 mm length securely. In addition, the strips have to be held in a way that allows to slightly bevel the edges, if needed. The idea was to clamp the material between to flat metal bars of sufficient stiffness. I happened to have to matching aluminium bars of 20 mm width and 3 mm thickness that once formed part of a jig and could be repurposed. The two bars were tightly clamped together and milled flat on the top so that they abut with sharp edges. Then, one edge was bevelled to 45° to give clearance for bevelling the styrene (or wood for that matter) strips. Unfortunately, the table travel of my mill is not long enough to do the milling in one set-up and I could not clamp the whole length of the bars in the vice, which resulted in some chatter marks. Not beautiful, but still functional. The clamping action is exerted by three thumb-screws for which holes were drilled and tapped. I stuck a strip of Tamiya masking-tape at about 0.5 mm distance from the top edge in order provide a stop for very thin and narrow material. Now the clamp has to be tested in anger, to see, whether it really proves useful – not all of my home-made tools that felt like a good idea, really turned out to be that practical 🫢 Building log to be resumed soon …

... it also a good idea to draw onto the template the shrouds as they should be. This shows you immediately, whether you are pulling them together by accident. Leave securing the knots until you are sure that everything is adjusted to be 'ship-shape, Bristol-fashion', unless you use some organic-solvent based varnish or shellac, which can be re-dissolved, should further adjustment be needed.

Absolutely ! This is what the engineer would call cumulative errors. For the outhermost shrouds, I would use a 'cow-hitch' (https://en.wikipedia.org/wiki/Cow_hitch), where the loose end returns on itself. This is the same amount of work as a clove-hitch, but looks more like 'real' thing.

Nice, consistent sanding job then 👍🏻

Nice clean work! How did you do the profiling of the roof, with a router, or by scraping with drawplate?
