Sail cringle holes with eyelet
wefalck replied to modeller_masa's topic in Masting, rigging and sails
I don't think fabric, with the exception of silk-screen fabric and silk-span (in European understanding), is suitable for models below say 1/50 scale. In any case, on smaller-scale models eyelets can be simulated by piercing a small hole with a needle, applying a drop of white glue on both sides and then opening up the hole again. For metal cringles the PVA can be tinted grey and then you turn a sharp pencil in the hole to give the cringle a metallic sheen. For the sewn one, you tint the PVA beige or beige-grey to match the ropework you are using. You can also make small hollow rivets yourself from thin-walled brass tube. However, you need a punch and a die, that you would have to turn up on a lathe yourself to suit the brass tube. -
I gather you are referring to the one below ? I have been watching some of the episodes in the past. Very instructive indeed.

What do we know about the origins of the lifebuoy?
wefalck replied to Sperry's topic in Nautical/Naval History
It seems indeed that the lifebuoy as we know it came around in the 1840s or so. In the 1980s it seems that more or less horseshoe shaped designs have replaced the 'classical' one. Before the time of steamships it is sad to say, there was not much real use for lifebuoys and the attitude to human life was also more fatalistic. Men typically went over board in rough seas and strong winds and at night, when it would have been very difficult to heave to, to lower a boat and start searching. Such manoeuvre would have put the whole ship and certainly the boat-crew into serious danger. Before smoke flares and battery-operated lights attached to lifebuoys, it would have been very difficult to find a man in anything else but a dead-flat sea. Therefore, I am not sure that these French lifebuoys that were suspended over the stern were really useful and not just prolonged the suffering My father was telling me, that his father (who was in the German Imperial Navy from around 1910 until 1919) told him that many sailors could not swim and would not want to learn it, because it would just make dying a much more prolonged process. Not sure that is true. He himself could swim, but many navy sailors, who came from inland areas may have not been able to. -
I think (without me knowing the actual practice), that you follow the sequence of the prototype: shaping the hull with the clinker planks, fitting the frames including the raisers/bulwark stanchions, and finally planking the bulwark.

In German, we have a saying: "a thing well-done needs time". As you don't do this for money, it doesn't matter.
-
I have a German sail-making book of 1887 that talks about cloth width from 60 cm to 70 cm. The width, I believe depends on the material and where it is manufactured.
-
Adding to the information overload and things that the shipwrights would have considered: - they had to balance between the width of the available wood and the need to have basically as few seams to keep tight as possible - too narrow planks at the ends are difficult to fit and you need 'meat' for the fastenings (tree-nails, metallic nails/bolts) - I am quoting from memory, but I think in Eric McKee's books on boats he gives a couple of rules-of-thumb, such that the fastenings should not be closer to the edge of a plank than its thickness to avoid splitting - this means that allowing for tapering there is minimum width for a given thickness that a plank must have before tapering - I seem to remember that there are also rules-of-thumb for the ratio between width of a plank and its thickness to avoid splitting and warping and in some navies such rules were written down, at least in the later 19th century - the available width of planks also depends on the type of wood chosen, the period (as already mentioned by Steven), and the geographic origin or location - oak planking in principle could be wider than soft-wood planks because oak trunks can grow thicker, but wide oak plans became increasingly scarce in Europe due to the massive ship-building activities from the mid-18th century on - for the same reason, massive pine trees in North America became less accessible after the middle of the 19th century, Baltic pine planks tended to be narrower - in many areas of Europe pine and related types of woods were imported by ship from the Baltic region (Finland, Sweden, Russia, the Baltic States, the eastern Provinces of then Germany and Poland; this put limitations to the size of timbers that could be economically transported - soft-wood was mainly imported sawn in Europe, which made stowage more economic than transporting whole trunks, which limited the choices to what was available on the market - certain ships built in SE Asia for European owners/navies may have had rather wide planks due to the availabilty there of large hardwood trees OK, that didn't really answer your question, I suppose, and doesn't help with the practical problem. However, the widths quoted by Steven and Allen are a good guide.

You are a dare-devil ! Cutting into the nice rail would have frightened me to bits ... However, it came out nicely. One tends to see a lot of these davits bent just from a length of round wire, but in fact, both diameter and cross-section actually change according to the expected stresses ... just going through that exercise myself - eight times and starting with a 1 mm brass wire

So the fore-mast sits in a kind of tabernacle ? How is it going to be locked against the 'baulk' ? Did you pin the cleats to the bearer ? Nice job overall !
-
When there is a deck-load of (sawn) wood, the shrouds would also be points to secure the load. On such quite small boats they probably would not have transported the kind of long logs and planks that came from Sweden and Finland on old barks, brigs and schoners to ports in Germany, the Netherlands, the British Islands and other European ports.
-
We probably don't know what the practice was at the end of the 17th century. On small scales I used a cow hitch as surrogate for the sewed-on eye-splice. Looking at your threads, I think it would be quite feasible to make a fake eye-splice and sew this on with a couple of turns of fly-tying thread.

Another Rigging Clarification Needed - Lifts
wefalck replied to BANYAN's topic in Masting, rigging and sails
I think John is right. The lower yards would not normally be raised and lowered, unlike the upper yards, where both, lifts and falls may be needed to move the heavy yards up and down. -
I didn't realise that the chocks are wood. So, yes, you would have to have something metal and if its turning it doesn't have to be so heavy.
-
Yes, that could be. Some kind of glutin glue kept from gelling by adding salt. Or it could be a thick shellac solution, one with lots of shellac and little alcohol.
-
Every organic solvent has a smell and some of them smell quite nicely (no, I am not a 'sniffer' ...). It depends on how big the area is to which you apply the glue. The main point is, whether the glue does the job. And: traditional hide glue does not necessarily smell very nice either.
-
That could be. In Germany the classical polychloroprene glue is Pattex and in my youth it was sold in tins. However, it was much for 'stringy' thatn the stuff in the video.

Paint or blackening
wefalck replied to Bill Hill's topic in Painting, finishing and weathering products and techniques
As always, the answer to the original question depends on what kind of model you are thinking of (and on the scale): for a model that shows off your artesanal skills, blackening is probably the way to go, while for a model that depicts the real life appearance of the prototype, painting may be more apropriate, as this is what would have been done in real life. I agree with 'grsjax', that blackening provides a better key for paints, particularly also acrylics, than the bare brass or copper. And: if the paint chips during subsequent handling, this will not be so visible. -
Keith, how is the attachment lock into the T-slot of cross-slide ? I don't seem to see any screw that pulls the fixed part down onto the table, against the T-nuts.
-
Ah, someone else, who got out the ball-turning attachment. Will be showing some results in my log soon. Would you mind showing your attachment to satisfy my curiosity ? Very nice anchors, indeed ! Will they stay in brass, or will you blacken them ? If the prototypes were galvanised, chemically tinning would also be an option.

Harriet McGregor by Boccherini
wefalck replied to Boccherini's topic in - Build logs for subjects built 1851 - 1900
Just discovered this log - beautiful wood- and metal-work indeed. Will keep following further progress ! -
Matching paints from different manufacturers really will be hit and miss. Not only will pigments be different, but as binders and solvents will be different, their levels of sheen will also vary. I think really the best strategy is one you already used, namely to decant a bit from the spray-can into a container. If you can find one with a tighly closing lid, then you may be able to store it for weeks or months, making the procedure less wasteful.
