Valery, that means then that sailors where standing in front of the yard, rather than behind it, when they were tending to whatever they had to tend to? Keith, double jack-stays became quite common particularly on the last deep-water sailing ships, when the massive steel yards would have meant that the upper part of the sails were actually lying on top of the yard and the foot-ropes were going around almost half of the yard. That part of the sail that lies on the yard doesn't pull, but would be subject to rot. So they move the jack-stay more forward.

These ropes are called 'foot-ropes' and the vertical ropes are the 'stirrups'. Valery's photos show very well the arrangement for yards that are meant for bending sails. On the first two pictures, however, there is a small error (sorry Valery): the stirrups should run over the back of the yard, not in front of it. The period photographs show why, so that the men can stand on the foot-ropes with the tummy on the yard. The yard on the KARLSRUHE only serves for the signal-halyards, so that the foot-ropes would have been used only occassionally, say to clear entangled halyards or something like that. So I would suspect that foot-ropes and halyards were galvanized wire rope, but probably served all over for protection. The stirrups perhaps were fixed to eye-bolts in the yard (no need for yackstays, as there were no sails) and had an eye in the end through which the footrope ran. I don't have access to my library at the moment, but once back home, I can check in Middendorf (1905), how footropes were made at the beginning of the 20th century. If I had to make them, I would use silk-covered copper wire (seidenumsponnene Kupferlitze in German) as is used for e.g. HF-coils. It seems to be easier to get again due to a fashion for analogue HiFi-equipment and restoration needs for old radios etc. Check Google for possible suppliers or ebay. The eyes can be bound with fine fly-tying thread and everything bent do shape and then painted black.

Yes, mica (or more precisely muscovite) can be easily cut with scissors or scalpels. It's one of the softest minerals actually. I gather modellers of 18th or early 19th century ships use mica, because that is what was used often on the real ship. Mica as such is quite brittle, but when frames more elastic than glass. Also, before float-glass was invented, it was generally cheaper than glass. Not sure, it will work here, as it usually has a slightly streaky texture - it is a mineral and not all the molecules are arranged perfectly.

Shame on me, somehow I missed this project ... very dramatic results indeed 👍🏻

Very glad to hear that your wife is on the way to mend. Well, we are not really acquaintances, but it was the second time within a few days that I had bad news about the health of a wife and this is always disturbing.

In theory, the window panes are inserted into recesses in the stiles and hold in place by strips of wood. So the stiles should be visible from both sides. That would be difficult reproduce in 1:87 scale, of course. Not sure what the physical size of the pilot house is, but one could use those very thin glasses as used in microscopy to cover samples. They are sold in packs of 100. They are very fragile, but can be cut to size with a scribing diamond. The stiles on back could be simulated just by paint. Otherwise, these very viscous acrylic gels used by model railway builders to glaze locomotive and coach windows could be a solution. I assume that is the same as the Testors product mentioned above. Talking about the stacks, if you allow me two observations: i think the stiffening bands are rather thick and it would be nicer, if it was bored out deeper. Personally, I would have turned them from either round aluminium or acrylic bar, which allows you to turn on the stiffening bands and to shape a nice flare. If you don't have a lathe, you could use styrene sheet around a wooden core.

Started catalogueing all my books nearly years ago. I am currently at no. 3514. Not all maritime though, lots of art books, 19th century engineering, and literature as well. Sadly we had to give most of my parents' library of another 3500 or so. I always carry a pdf of the latest MS Excel spreadsheet on my telephone in case I run across something interesting in a used bookstore - prevents me from buying duplicated. I largely stopped buying pre-1900 books in recent years (with some exceptions), as much of it is now available as digital copies. Saves money and space on my overflowing bookcases (30' x 8'). BTW. Everything that is marked with a 'B' in this list is an original hardcopy: https://www.maritima-et-mechanika.org/maritime/maritimebibliographies/maritimebibliography.pdf. But that was actually thread-drift. Back to the original question: By the middle of the 19th century, blocks and deadeyes were virtually flat on the surfaces. They were much easier to machine that way. Block- and deadeye-making machines were basically the first template-controlled lathes and milling-machines.

What I like about my toolmaker's vice shown earlier is that it has two rabbets in the jaws that allow you to clamp shorter parts without the need of parallels. Talking about parallels to prop up shorter material in a vice: I often use pieces of drill-rod instead - it's a lot cheaper than sets of parallels.

👍🏻👍🏻👍🏻

Sorry to hear these disturbing news. We keep fingers crossed that the surgery is successfull !

Watched last night the latest episode on the restoration of TALLY HO on YouTube and the precision of those woodworkers is just amazing always ....

I am currently using so-called zapon-varnish for such things. It dries within minutes and was originally used mainly used to varnish silver and brass to prevent it from tarnishing. Old-fashioned nail-varnish is very similar in composition (not the modern acrylic one) and probably easier to find, though over here in Europe we find zapon-varnish in most DIY stores. Another option would be shellac, particularly the one in flakes that can be mixed with alcolhol to give any consitency, from honey-like to watery. It's an old-time means to stiffen paper, felt (as in bowler-hats), etc. It dries slower than the above varnishes. All obviously dry glossy, when applied to thick, so one may need to give it a spray with with some matte varnish. The nice thing is that all maipulations are reversible using a fews drops of aceton or alcohol. If you are not happy with the lay of thatch, brush some solvent over it, adjust and brush again some varnish on it. Repeat until you are satisfied with the looks.

What kind of varnish do you use? Personally, I would use one based on organic solvent, as a drop of solvent would soften it, allowing adjustments.

Not sure, what the final verdict on the thatching is now, but one could also use a technique akin to that that was used on the rial thing: put a thread of about the same colour as the thatching material and twice the length of the rancho on the double sided tape, place a bunch of the material on it, lay the loose end over the bunch and fix with varnish. Then put thread that was on top onto the tape, place the next bunch, and lay the thread that was on the bottom over it. And so on. In this way you kind sew the bunches together and they should lift of more or less as a unit. In real life the thatch would have been sewn to the rafters using hemp cord or a cord made from straw twisted together. The house thatchers had special long needles for that. Thinking about that using such sewing technique, you may be able to do the thatching directly on the rancho ...

I gather Brian can comment on this with more practical experience. However, usually the power of the laser can be modulated as well as the speed of travelling set, both of which determine the penetration of the laser-beam. There is a minium width of the cut plus kerf, but one can make the slots wider by running the laser with a slight off-set several times. The char from the laser could actually be beneficial as it protects the wood underneath from further smoldering during soldering.

He could also use the laser-cutter to engrave those slots ...

There is also a five-language edition, but I don't know, whether there is any digital copy somewhere on the Internet: PAASCH, H., CHALLAMEL, P., MATTHIESEN, F.E., BUDDE, A., MONTOJO, P., ROMAIRONE, G.

Coming on nicely ! Concerning the rails: - I think, if you cut a half-round seat for the handrail into the uprights using a burr and then use solder-paste that should work. - likewise for styrene rods, a half-round seat in the uprights and other joints locates the parts and requires less cement - I would use styrene cement, which welds the parts together, rather then glues them.

It's a universal motor and these starting capacitors don't live for ever. Should be easy to replace and the motor will be back to life. Check also the brushes, of course.

To be honest, I wouldn't worry unless you want to drill holes below say 0.3 mm diameter. The machine is probably adequate. If you happen to have a dial-indicator, you can chuck up a drill and check ...

It's not only about play. There are two key points that determine the 'run-out' of a drill taken into a chuck or collet: - how concentric is it held with respect to the rotational axis of the spindle, and - how parallel is it held with respect to the rotational axis of the spindle If the drill was perfectly parallel, but not concentric, it would rotate in an imaginary cylinder around the spindle axis. If the drill was not parallel, then it would rotate in imaginary cone around the spindle axis. In both case the drill tip moves around in a circle, which causes sideway stresses on the drill, results in holes larger than the drill-size and can lead to breakage of the drill (particularly when using the fragile carbide drills). So the chuck can sit tight on the spindle and the drill tight in the chuck, but you still have the above phenomena.

Depends on how much you are prepared to pay for it an how well the connection between the spindle and the chuck is machined. If you pay several hundred EUR/USD/GBP for an Albrecht-chuck that has a taper at the end that in turn fits into a concentrically machined female taper in the spindle, you get the least run-out off any chuck you can think of. Jacobs-chucks inherently have a bigger run-out than collets. So whenever possible one should use collets. For instance the PROXXON-drills have a collet-seat machined into their spindles, so you have the option of either using a chuck that screws onto the spindle or the collets. I don't know what the spindles on these drills look like that started the discussion. Perhaps they are already have a female taper for ER collets? If not, perhaps one can replace the spindle with a commercial one that has the right taper - they are cheap and can be bought in different diameters from ebay et al. For such a machine, ER11 collets would be sufficient. They can take drills of up to 7 mm diameter. As always, you get the precision you pay for ...

Agreed, very well done! Why was the chain on port doubled? I could imagine that it has to do with a mechanism to adjust the rudder midship and to tighten up the chain, but cannot work out its function ...
