    That is just nuts. I'm sure someone has found a use for such tiny objects too. Maybe in the electronic industries for printed circuitry eh?

     

    Unlikely. As an electronics engineer, i can tell they are way ahead of this size. Chip technology uses photo etching and/or metal steaming-vaporising to build the circuits. They are really in nanometer scale. Nowadays a semiconductor in a chip is 5 nm wide, and now trying to reach 2 nm, but due technical difficulties (not the size, but the intereference between neighboring transistors: electrons can travel between them) those chips are not yet reliable.


    I bet diagnostic and precision instruments industry who can use this level of accuracy in printing.

    Quick question about scale. (I'm real bad at math - it ain't my best friend here)

    working with the scale of my model 1:78 - is that 1 inch to every 78 inches, or 1 foot to every 78 feet, or is that the same?

     

    Hi John,

     

    thats the same, and you're correct. If you measure an inch on the model, thats 78 inches on the real thing. Or, other words: a foot long model would be a 78 feet long boat in the reality. If you have a Bavaria 35 yacht which is exactly 35 feet long, its model will be 35/78=0.448 feet, so 5.378 inches in 1:78 scale.

    If someone can give you the exact plate sizes, just divide them by 78 and you will get the scale size.

    Yes, sort of. In the screen capture below you can see that it's actually the lookout's binoculars that are held by the frame (which is slightly different in this image from the type provided in the kit). The lookout uses his hands on the frame to adjust elevation. The most commonly used US naval binoculars were 7x50s that weighed 2.7 lbs, so using one's hands to hold them at eye level for long periods would obviously be very fatiguing.

     

     

    Those brackets purpose primarily the direction and elevation measurement. On the picture, you can see a bearing scale ahead of the crew, and on his left side you can see the elevation scale. With those scales the watchmen can give precise direction of incoming threats. Their binoculars were equipped with a very basic rangefinder in the right eyesight.

    Exposire during childhood?

    The shop I went to when I was around 10 years of age had a wall full of revell and airfix (mostly planes, and a Vasa, a hms victory and a santa Maria).

    They also had some card (Leon Schuyt: frisian farmhouse, limburg farmhouse, city tower from Amsterdam). I’m pretty sure that mid-seventies that was the situation in all shops over here. 

    And also: on meetings it is the platic guys that are very impressivevwith their weathering- and upgrading techniques. Card  is something for children that need something to do on a rainy sundayvafternoon :)

    Hi Jan,

     

    yep, same situ here in Hungary. However, i was in a shipmodelers' meeting once, and a guy came with a 40*40 cm chess set, with all the board and figures was constructed from card. Of course, the figures were all different type of ships. The pawns were small boats with a single latin sail, the knights were frigates with 2 masts, the king was a ship-of-line and so forth, of course identical ships with black and white sails. You should have seen the dropped jaws there (mine included).

    I think the hobby shops just followed the demands, shipmodeling is not too familiar due small scales, much more modelers interested for armor and planes. Also i remember when i had to order my Titanic abroad (Academy 1:350) in 1995 because nowhere i found a kit before the 1997 film, which skyrocket the interest again to her lately. Still have the original Korean instruction sheet :)

    When dropping the chute by releasing the guy the chute lost its energy, floated back to the lee of the mainsail, and was pulled down by hauling on the sheet.  Once under full control by those in the cockpit it was bundled up and taken below to be repacked.

     

    It depends on the wind direction. In full backwind run there is no lee side (of course there is, but the spi must be on luv), and sometimes no space to steer the boat closer to the wind, therefore need to collect the spi in full 'energy'. This must be controlled by the sheets behind the foredeck crew and need great attention of the skipper.

    I never used the lazy guy configuration either, but seen this one on a 35ft daysailer. Although our soling had double sheets, but the small sets used in very light breeze only when the stronger one kept secured.

    Anyways, since the fashion of reachers and fixed bowsprits, our spinnaker knowledge is a bit obsolete.

    I thought i had better look up what the internet says about the orientation of the spinnaker pole beak:-

     

    Whisker poles should be flown with the jaws facing down. When taking down a whisker pole, the jib sheet usually wants to drop down-and-out of the end fitting. Spinnaker poles are flown jaws facing up, as the spinnaker sheets usually want to lift up-and-out of the end fitting. 

     

     

    Hi Keith,

     

    Releasing spinnaker sheets upwards is dangerous. In this case the spi can get wind and start flying like a giant parachute, pulling the now breaching boat, as the halyard and the lee side still connected. I know a boat sunk due this mishap. Similar event pictured here from the 2010 world's championship. Anyway, i found references that spiboom used with upwards looking latch (jaws up) position too, but i would avoid this on my boat for sure.
    But i don't want to waste up your build log with my mumbling, also i believe all of you guys have experience sailing smaller or larger boats.

    I don’t remember but I agree with Tom.  When drawing, the spinnaker floats upward. If the jaws face up, when gybing or taking down the chute opening the fitting  releases the guy.  If it faced down the upward force of the chute would require the foredeck crew to manually dislodge the guy; difficult as the end of the pole is outboard.

     

    By the way my comment above is incorrect.  When taking down the chute in the lee of the mainsail or foresail the only line available to the crewman hauling it down is the sheet

    Folks, just take a look my avatar: as a soling racer i'm quite expert handling the spinnaker :) Of course, you are too. The latch always facing down, allowing the outer (luv side) sheet to fall out from, and allowing the spi to come back to the lee side of the main. Usually jibs are lowered when spinnaker in use, if the jibs are on, the spi will get less wind and will much harder to handle it correctly due the jib's vortexes.
    Collecting the spi rod (spibaum in terminology) is according the taste of the crew: can be the first to avoid ripping out the spi, or could be the last to give time the crew to pack up the spinnaker, raise jibs up, new course set, and gather the necessary speed - then easily collect and store ready. Larger boats keep the spibaum latched to the mast, just pull it up in vertical position.

     

    Roger, when the chute falling, the crew will pull the sheet first, then grab the spinnaker's lower leech, and manually collect it for a long 'sausage', the lee side of the mainsail allow it to do - it is practically impossible when the spinnaker is full because the pulling force easily catapult the crew out from the boat, even on smaller boats like Soling. Then the crew collect the sausage under the deck, carefully to keep the sheets clean, otherwise the next attempt to raise the sail will end to pull up a giant bra.
    Dinghies can collect the spi on luv side, to be ready for next tack on olympic course.

    Just realised...shouldn't be posting photos of my build on your thread! Sorry!  You can ask the editor to remove them or maybe you can do it yourself? Not sure.

     

    I wouldn't delete them, it is a good reference. Anyhow, you can start your own build log, and link the pictures from it. Personally i'd love to see your log as well, i'm always impressed by models with interior.

     Chris, do you think a vac pen would be helpful in card modeling? There are several models out there, below are a couple of links as examples.

    You asked Chris, so sorry for barking in. I do use a spot of blu-tack on a toothpick, it is much cheaper. Cons to have to wait till the glue fixes, to release the grabbed part.

    Here, Kevin -- I have created a Polish-English dictionary for you based on my "extensive working knowledge" of the language:

     

    • okrety: ship
    • klej: glue
    • drut: wire

    Okay, that's all I know. For the rest, you're on your own. 😜

     

     

    Not at all Chris, you forgot the most important word: Nazdrowie!  Believe me, 'polak' has excellent sort of vodkas. It is must for ship modelling Kev!
    Good luck for PoW, i will follow you.
