  1. Yes, such a larger footprint baseboard adds to the stability of the machine, particularly, when the x-y-table is moved out far. Beware, however, that you probably will find soon that the two drawers will not accomodate all the addtional parts for the machine you will accumulate over time It may be an illumination artefact, but it appears to me somehow that the column is mounted on the wrong side of the base !? Looking from the front, one should see the full lenght of the x-y-table ... or what is the dark rectangle underneath the head ?
  2. To me the difference of a thimble/heart and a bullseye is that the thimble/heart is meant to keep the eye in a rope/wire at a safe radius, when attached with a shackle or hook; it also protects the rope/wire from chafing, when there is a movement between the eye and the shackle/hook. To the contrary, a bullseye either serves as one part in a purchase or an arrangement to redirect the run of a rope, when there is no movement of the rope under normal circumstances. It appears that bullseyes were favoured over deadeyes when used in stays from the late 18th century on, though 'traditional' Dutch (merchant) vessels seem to have used deadeyes right to the end of the 19th century. The explanation above concerning the advantage of a bulleyes over a block is certainly true for rope-rigging, while from the later part of the 19th a block with a metal casing seems to have been used in conjunction with wire-rigging.
  3. Did the laser work with polystyrene ? I gather one would need a ventilation hood because of the fumes.
  4. Fly-tying thread may be a bit stiff, but I am making my own rope from it and rope is less stiff than the thread itself. A bit of matt varnish (or black paint for the rat-lines) keeps things in shape.
  5. Which one was it, I have seen several of such machines on ebay and crowdfunding sites. The laser-cutting capacity seems to be limited for technical reasons, as more serious lasers would require more serious cooling arrangements.
  6. Wouldn't be another method for stowing the sheets to pick them into the same shackle as the downhauls ? I also seem to have them seen forming a sort of triangular spidernet between the stays. In this way they are not liying around on the forecastle.
  7. I actually do have Parallels Desktop on my Mac, but would have preferred a 'native' solution. It is quite strange that you can get drivers for any odd printer, but not for those CNC ord 3D-printing machines. Perhaps the number of Mac-users is too small - so a lot of the graphics people seem to use Macs.
  8. Without meaning to be offensive, but somehow I don't get the fuzz about this . These are calculations one learns in primary school ... ok, if you are Imperial you have to handle different units (feet, inches, 'thou', ...), but this is just one more division/multiplication.
  9. Just to add to this: beds were also often raised higher above the floor than it is usual today, because obviously the higher you are in a room the warmer it is. I suspect that in Britain they still do this today, as British houses traditional are not very well heated. For the same reason four-poster- and alkove-beds, both with curtains, were used.
  10. Doors were low to keep the heat in the house and beds short, because people slept in the fetal position, also to loose less heat compared to sleeping with stretched out limbs.
  11. Indeed, there are considerable regional differences today and were presumably in the past. I recall the sensation (hightened by the fact that it was a time of civil unrest) of walking through the streets of La Paz (Bolivia), a gringo towering above everyone, while only being just 180 cm tall - quite a difference to walking the streets of say Amsterdam, where I felt rather diminutive However, like in real life, not only the absolute height would be important for the scale impression, but also the proportions. While certainly there is a distribution of proportions across a given population, some peoples tend to have longer limbs and shorter bodies, while in others it is the inverse. The latter would appear smaller than the first group. Head length to body length ratios are also important, a big head making a person appear to be smaller. In this context it also interesting to compare artists' rendering with real life. There have been periods (e.g. during the 'gothic'), when people, particularly gentle-folks, were portrayed with a 1:12 ore more head:body ratio, while in real life it is more between 1:8 and 1:10. This reflected aesthetic concepts, as well as class distinctions. So the story turns around, as better fed gentle-folks in any population would grow taller than more deprived classes subject also to hard labour.
  12. Good work as usual ! For the seizings I tend to use a clove hitch with half-hitches added as needed. To me this gives a more prototype appearance.
  13. Is anyone aware of such a small CNC-mill/router that can be controlled from a Mac ? The guys that make the Shapeoko 3 also make a thingy called Nomad that seems to work with Macs, but I found it too big and pricey. Most small, cheapo machines only seem to made to work with Windows ...
  14. In the days of pocket calculators (now almost gone) and smart phones scale conversions shouldn't be an issue. Simply take your calculator and divide the prototype measure (ideally in the same units as you will be using in model construction, e.g. millimetres or inches) and divide this by the scale you are working in, say 1/60. In this case divide everything by 60. If you are on inches and feet, unfortunately, the story is not so simple, unless you use 'thou(sands of an inch)' - converting into 1/16ths, 1/32nds, etc. needs one more calculation step. I agree, for those, who are not metric, a ruler might be simpler
  15. There are various UK-based small manufacturers who offer white-metal figurines in O-scale suitable for the 'Victorian' period. Have a look at this trader's Web-site for a start: http://www.scalelink.co.uk/
  16. Making served eye-splices is a challenge that has bugged me for years, particularly in smaller scales. Looking at your method, I was wondering, whether one could not serve first a short length, then form a 'false' splice by stiching the loose end two times through the standing part, set the splice with lacquer or glue, and then continue to serve the standing part. This would result in a less bulky splice, as it would be served over only once.
  17. Nail varnish is a solution of cellulose nitrate. The same stuff, zapon, is used to protect metals, such as silver and brass, from tarnishing and can be bought in DiY stores cheaply. I have used it for decades to fix rigging, because it can be dissolved again with a drop of acetone and corrections made. Beware, today there are also nail varnishes based on acrylics. These cannot be dissolved again very easily.
  18. Indeed, dafi made a lot of experiments with fly-tying thread for small scales ... Personally, I found the Veevus-brand from Denmark the best: http://veevus.com/. They have various useful colours, such as greys, tans, and of course black. Also they go down to 16/0, which is useful for making really small-scale ropes. Usual disclaimer: I do not have any business-relationship with the company other than as a customer. I got the stuff from various ebay-sources btw.
  19. Personally, I would follow the advice of the others and use fillers between the bullheads of the kit ... Solid hulls can have long-term problems, depending on what wood was used and how they were constructed. If you use a single log of some wood with prominent grain it may warp, depending how it was cut from the tree. A layered, bread-and-butter construction avoids this, but then you might as well use the bulkheads of the kit. In bread-and-butter construction with time the layers may also come apart and should be screwed together in addition to the glue. For stationary models, when you don't want to show the interior, I would always go for fillers between bulkheads. This makes a very solid and rigid construction and allows good fairing of the hull, if the fillers are softer than the bulkheads (but not too soft).
  20. Pat, that looks like neat progress ! May I ask a counterproductive question ? Why were the davits made from white metal ? If they were brass, it would be indeed a lot easier to solder bit and pieces on. Normally, the davits would have a sort of short piece of tube at the end, in which an eye-bolt swivvels to which the block for the boat-haliard would have been shackled. The swivveling motion is needed so that the tackle is not being twisted as the davits are swung out. The stays would be attached to the top of the eye-bolt, rather than the davit itself. I have seen the cleats for the boat-haliard attached to the round davit by tight wire windings, just as cleats would be attached to shrouds with a thin line. That can be easily reproduced with say 0.05 mm copper wire. I did not examine very closely the images of your prototype, whether such solution would be correct in this particular case, but I think it would be appropriate for the period.
  21. Ooops ... I would have probably re-enforced such masts with a steel wire of suitable diameter right away. If you are lucky, you might still be able to drop a wire in that just sticks out a bit over the fracture and lift the upper part over it, so that it serves as a locating pin before glueing the parts together again.
  22. May be the changes in the plans reflect the changes the original may have seen over the years, while in preservation ? Wasn't she made fit for the sea again in 1976 ?
  23. Very clever tool that little thing to find the centre or quarter a tapering spar. Have to remember this
  24. Excellent work, as always. Like the 'iron'-work. Using an end-mill to drill obliquely into surfaces or into curved surfaces is a good practice I am also using often. One has to be sure, however, that it is an end-mill that cuts across the centre.
