Most 'hobby'-shops tend to sell things in small quantities at elevated prices to innocent/ignorant modellers. Very few tools are specifically made for us, but rather are adapted from other trades, includings medicine, jewellers, horologists, dentists, etc. It pays to check out the tools of profession that work on small and delicate things. Whatever you may think about ebay, it has opened up the market for all sorts of things that would be otherwise difficult to come by or might get thrown into the (recycle) bin. I got a life-time supply of scalpel blades in all sorts of shapes at a very good price from an ebay-dealer, who sold sterilised scalpels in packs of 100 that where beyond the 'best before date', i.e. the date up to which the manufacturer guaranteed the sterile condition. Presumably a medical supplier or a hospital had thrown them out.

Scale ?

These are the same as the 'real' ones. I usually get away with the half-hitch, double-half-hitch, clove-hitch, reef-knot and perhaps the sheet-bend. There are lot of Internet-resources on how to tie these knots, including animations (if you a geometrically challenged). As to the shellac, which usually has a slightly orange tint, you have to try it out on the material you want to use. The more it is diluted the less the colour becomes visible, but also its sticking capability reduces. Like so many things in modelling, you just have to try and find out what works best for you and the materials you are using.

Personally, I am not very fond of brush-painting acrylics for a couple of reasons: - one has to work very fast, as acrylics dry very fast, in order to avoid brush-streaks - acrylics remain slightly rubbery for a very long time, days, if not weeks; until they are not thoroughly hardened, it is difficult to sand them - one would need to paint the surface in one go, as quickly as possible and without interruptions, i.e. wet in wet. I am not an expert in high-quality brush-painting, but one of the techniques/strategies is to rub run down the layers of paint and then to repolish the last one to the shine desired. This is very difficult to do with acrylics for the said reasons. The brush size really depends on the size of the surface you want to paint. So, today, as air-brush equipment will cost you probably less than a meal for two in a good restaurant (depends on where you are living, of course), there is hardly a reason not to use spray-painting. And for this, acrylics are ideal.

Do a bit of searching on the Forum, the various techniques and options for materials have been discussed before here. Just to make it clear, there is/used to be finely woven silk (silkspan in the USA, but this may be product name) and silk-paper for covering model aircraft wings and other parts. Both materials can make useful sails and have their pros and cons. It depends inter alia on the scale one is working in. A substitute for 'silkspan' may be also the fabric that is used for screen-printing, but I have no practical experience with it. It seems to be easier to get than 'silkspan' these days.

Over the weekend I have been to London and as our hotel was around the corner, my wife suggested that we visit once more the Wallace-Collection. Sir Richard Wallace and his father have put together also a nice collection of Dutch paintings, including a good number of seascapes. For a colleague over in the forum of the 'Arbeitskreis' I took pictures of several hoeker-like vessels (https://forum.arbeitskreis-historischer-schiffbau.de/viewtopic.php?f=16&t=1874) and also what I think may be an early form of a 'boeier'. In any case, judging by the carved and gilded decorations, it is obviously a pleasure-craft: J. van der Heyden (1637-1712): View of the Westerkerk, Amsterdam. Perhaps Ab can correctly identify this vessel ?

druxey, you are right in principle and I also have been an advocate of 'permanent' materials. On the other hand, I have a roll of gummed packaging tape that by now may be a hundred years old, considering the way it came into my possession, and it is still good as new. Perhaps over a 500 year time-scale things may be different ...

I only recently learned, when visiting the London Canal Museum last weekend, what Esparto Grass was used for: paper-making. It is mainly grown in SE Spain, in the provinces Valencia, Alicante, Murcia, and Almeria. The Spanish name is atocha. Perhaps, this is why Madrid's main station for trains to the South is called Atocha, leading to the plains, where Esparto Grass grows.

Perhaps I wouldn't use the word 'coating' and the underlying concept. The idea is to soak the rope material in order to stiffen it. When soaked-in, the lacquer/varnish becomes invisble, a 'coating' by definition is a visible layer.

Nail polish is essentially the same as zapon lacquer, except that is comes in smaller bottles and, hence, is more expensive ... Beware, some nail polishes are acrylic-based and do not dissolve readily.

This topic seems to pop up over and over again. A search through the various building logs might be useful ... As druxey said, the 'dimples' are barely visible on the real ship from a view metres away. They are, however, one of those details that, when left off, may make the coppering look rather sterile. On the real thing you can see that there is something, but you can't really tell what it is, when you are some distance away. What you can do depends very much on the scale you are working in. In scales of 1:48 or above, I would perhaps imprint lightly the nailing into the copper sheet using a copying wheel (sewing supplies) and then flatten them again from the back with a round piece of hard wood. This gives you quite realistic 'dimples' that are not proud of the surface. There are very thin copper adhesive strips where you may use the same technique for even smaller scales. I have used them for rivetted plates, but not for copper sheathing yet using the above technique. Always use a glue that sets by evaporating the solvent, i.e. contact cement, and not something that polymerises, i.e. CA cement. Copper ions can inhibit the polymerisation. Also CA can react with the oxide film on copper, leaving bright spots, and it is difficult to remove excess cement. Excess contact cement can usually be wiped off with a solvent.

I should have added that the varnish I use is the kind of thin cellulose varnish that is used to protect silver and brass ware from tarnishing. In continental Europe we call it zapon lacquer and it dries alsmost invisible.

Is there a particular reason that you are building at such a large scale ?

Any equipment that constitutes an Ohm-resistor (collector motors, soldering irons, incandescant bulbs, etc.) can be controlled with a simple dimmer - but check that it is rated appropriately. Dimmers are either available for wall mounting (which can also be set into a workbench) or as 'plugs' to go between the plug of your equipment and the wall socket (hence, no installation is required). I have a dimmer hooked up to a foot switch from which I run all machines. This has the advantage that they are only under power when needed and that you can interrupt them by simply lifting your foot. The rpms are preset, so you can return to the same setting by pushing your foot down.

The tool of choice would depend on the location and its accessibility. I typically use the following: - micro-scissors for eye-surgerey (Castrovejo-style); they can be very expensive, but I got mine as 'seconds', which are good enough for our purposes - check ebay et al., where one can find all sorts of medical instruments these days; the most useful is the curved type, as it lets you get close to the point of cutting. (Found even on Amazon ...) - ordinary scalpels with replaceable blades - broken-off pieces of razor-blades - there a special holders for these, but they are ridiculously expensive; you can hold it in a pin-vise with a double-slotted head/collet; razor blades probably give the cleanest cuts after scissors. - antique biological lancets for tight spaces; they have to be honed on an arkansas stone to have a really keen edge. Don't use your scissors and lancets for anything else but rigging work. I soak all splices and knots in clear varnish, rather than PVA or CA glue, as I can loosen them with solvent, should the need arise. Incidentally, you will find that splices are much more common than knots. The latter are mainly used to belay ropes, rather than attaching them to say blocks. You can fake splices by drawing the end twice through itself using a needle, cutting off the excess and then roll the splice between your fingers with a bit of varnish on.

Following Basil Greenhill ('Archaeology of the Boat'), the shell-first method may have originated in extended dug-outs: the dug-out was heightened by adding planks; dug-outs were also widened by heating them and spreading out their sides. Eventually, a dug-out was a too small a base for a boat. Also very large trees became increasingly scarce, so that the back-bone was reduced to a keel or floor-plank. Some native craft around the world (including actually Europe) were built until quite recently on the basis of extended dug-outs. On the other hand, the shell-first method, commonly associated with the wood-rich northern countries, seems to have also been used around the Mediterranean and other places of th World. Edge-fastened (with tenons and mortices) planks were assembled into shells with internal structural timbers being added later in the process. Edge-fastened planks, whether overlapping (clinker) or butting against each other is the key feature of the shell-first method. The other way to conceive a boat is to cover a structural framework with a skin, be it hide, cloth or wooden planks. Here any edge fastening (e.g. by sewing) does not give structural strength nor shape, but only serves to make the skin water-tight. In frame-first building the wooden planks are never edge-fastened, but only attached to the frame.

I know what you mean, I admire people, who get whole battleships done - we are getting lost already in the details of such seemingly simple projects ...

You are welcome I am just sharing my book knowledge augmented by 30+ years of tinkering in the workshop ...

Exactly. I am actually using one of those plug-in dimmers that go between the plug and the wall socket.

Of the single shrouds, one would go around the front of the mast and the other around the back. It would be the art of the rigger and the mate/officer in charge to make sure that all shrouds are set in a way that they take up the strain relatively evenly distributed.

Interesting. I would have thought that the double-shrouds would weigh down on the single ones and through friction secure them additionally, thus taking some of the strain from the lashings (which, incidentally would be double or triple, as for the lower end around dead-eyes).

Instead of a splice, the single one may also be just lashed together as the double one: each side reaches over to other side, together forming a loop. The correct method would need to checked in period reference books.

Plank-bending inserts for soldering irons have been on the market for 50+ years for a few quid. Essentially, they are rod with a disc or something egg-shaped in cross-section at the end. You can even make one yourself, dito the wooden die for shaping. Get yourself a heat-controlled soldering station with exchangeable tips for the same amount of money and you can use it for soldering too

As an avowed tool-junkie I would love to have a peek into his tool-chest ... Sticking sanding paper to palette-knives sounds like a good idea. Although I have 'inherited' a bunch of them from my mother, when she went to a retirement home and had to give up porcelain painting, they are too big for my scales. Perhaps one can make ones own micro 'palette-knives' from bent thin steel strips with a suitable handle. They should have the same size as toolmakers rasps/files or watchmakers echappement files.

Carrier hardness vs. hardness of the abrasive vs. hardness of the material to be worked on is actually very important. If the carrier is too hard, the abrasive gets squashed and becomes ineffective, if the carrier is too soft, the material may smear over the abrasive, rendering it ineffective. This is why we have relatively soft abrasive wheels with red iron-oxide as binder and the grey ones with harder Si-carbide as binders. Soft polishing pastes (say 'rouge' in oil) would smear around a steel lap and not do anything. An old-time watchmakers polishing kit would contain lapping disc made from steel, bronze (bell-metal), and boxwood. A little anecdote: as a student I worked in the institute for tunnel engineering of the ETH in Zürich (Switzerland); my job was to prepare samples for testing different pre-cutting configurations for tunnel-boring machines. For this I had to drill large cores (150 mm diameter) from different rock types, ranging from granite to sandstone. We had a large drill-press and a core-drill with a diamond-impregnated rim. I was really struggling with some of the granites and we thought something was wrong with the core-drill. So I took it back to the distributor; he chucked it up in his concrete-drilling machine and went through a slab of high-quality concrete (from a nuclear power station) like butter. He explained to me that we just got a drill with the wrong binder (brass) and that it smeared over the diamond grains, when drilling in very hard rock, such as granite.
