    Doreltomin reacted to trippwj in Historical Units of Measure   
    In the US, the foot is based on the International Foot which = 0.3048 meter.  The US foot is essentially the same - the conversion just takes it to 10 decimal places (1 US Foot = 0.3048006096 meters).  For those of us geeky enough to want more info, the National GS has a PDF format document from the National Bureau of Standards in 1959 (NBS is now NIST) called Refinement of Values for the Yard and Pound that defines the "U.S. Survey foot" as 1200/3937 meter or 0.3048006096 meters. For more detail on the SI units, see http://www.nist.gov/pml/wmd/metric/metric-program.cfm
     
    The SI meter is now defined as the length of the path traveled by the light in vacuum during a time interval of 1/299,792,458 of a second.

    Doreltomin got a reaction from WackoWolf in Historical Units of Measure   
    Hello Alan,
     
    I took my own copy of Wolfram zu Monfeld "Historic Ship Models"  and opened it at page 66, and found the said list of different measurements. I believe we have the same book, is it the one published by Sterling Publishing Co, Inc. NY?  
     
    There's indeed a list which gives the English foot to be 308.0 mm, but I wonder if this is right. To my knowledge, the dimension of English foot did not change at least from the 17th century until nowadays, so if they did change anything into the 19th century it was the way they "translated" it into a meter, not the dimension itself. 
     
    Moreover, in my calculations I always use the English inch of 25.4 mm yet I have an old Hütte engineer's manual which I have inherited from my father which gives one English inch to be 25.399956 mm. The difference is very small, yet as you said, if you add many inches together, it can get a significant amount. 
     
    This only happens if you work your model metric and always try to "translate" your measurements from the old imperial units into milimeters.
     
    Here is the really nice part when working with imperial units: if you use an imperial scale and use a measuring tool divided in inches and fractions of an inch, working for example your model to a scale of 1' = 1"  your model will always be true to its scale of 1:12. Moreover, if instead the English foot you will use a measuring tool divided into French feet or Swedish feet to measure a plan which is made into these units, the model will still be 1:12. Of course, this only works if that unit is sub-divided into 12 inches. It will not work for the Amsterdam foot which was divided into 11 duimen. Don't ask me why, and moreover, how on Earth they managed to divide that foot into 11 equal parts   
     
    So if using a different foot or a different way of translating your foot into milimeters, your model will still be accurately proportioned (supposed you made it accurately) only the scale which you know to be a true 1:48 may in fact be 1:51.5 or 1:46,79 or something like that. It's just a question of numbers. This applies as well with the old Navy Board models, many of which are known to be built in 1:48 scale, yet if measured carefully, some of these models show not to be built at a true 1:48 scale but to a slightly different scale, depending on which measuring tools the model maker used and how accurately these tools were made. 
     
    Here:  
     
    http://en.wikipedia.org/wiki/Foot_(unit)
     
    you have an abstract of the measuring ways used in Europe from the early times (it is a wiki source so use with the due caution as it is known for the wikipedia sources not to be always reliable) and here:

    Doreltomin reacted to ccoyle in Pt. IV: Tools & Other Supplies   
    The tools needed to get started in card modeling are ridiculously few.  Basically, you need a cutting tool and some glue.  Everything else is optional.
     
    Here's some basic tools:

     
    You'll need a self-healing cutting mat, available from most office supply or crafts stores.  Next, you need something to cut with.  Notice the lack of scissors in the picture.  Most card modelers rarely use them.  Instead, your garden-variety craft knife will do the job nicely and with more precision.  Get a good supply of #11 blades -- card can be surprisingly hard on them.  A steel rule is a must, not just for measuring, but more importantly for cutting straight lines.
     
    Glue is, of course, essential.  A variety of glues will do the job, and each has merits and drawbacks.  Good ol' PVA glue, either white (such as Elmer's) or yellow (wood glue -- hey, paper is wood, you know) are good general purpose glues with one proviso: it must be remembered that PVA glues are water-based, and card or paper will absorb the glue and deform.  Thus, PVA is not good for gluing large surfaces together.
     
    Cyanoacrylate glue, or CA (commonly known as 'Super Glue', which is a brand name), has its uses in card modeling.  Fast-cure CA can be wicked into card stock to stiffen it, and medium-cure CA is useful for gluing parts made of different media together, as well as for paper-to-paper bonds.
     
    Contact cement (not to be confused with rubber cement) is a non-water-based glue and thus good for gluing large surfaces together where severe warping would occur with a PVA glue.  Contact cement sets rapidly, so repositioning of parts once they come in contact with each other is iffy at best.
     
    Modelers in Europe have access to UHU-brand glues that some modelers swear by.  I haven't come across any myself, so I haven't had a chance to try them out.  Polish modelers, who seem to be born with a master card modeler gene in their DNA, use something called 'butapren'; I'm not a chemist, so I'm not familiar with what exactly butapren glue is, and it doesn't seem to be easily available in the US, possibly because it is a favorite of glue sniffers.  Perhaps someone with knowledge of this substance can fill us in.
     
    Now, on to some optional stuff that you'll probably want to have on hand:

     
    From left to right we have:
         blackened, annealed wire - an assortment of diameters is useful for making gun barrels, railings, etc.      styrene rod - card can be rolled into tubes, but for tiny tubes, styrene is often a better choice      assorted paint brushes - for painting, but also for aids in rolling tubes      tweezers      paint, marking pens, or other media for coloring cut edges (more on this later)      calipers - for measuring card stock thickness, especially when laminating sheets together      hobby pliers (not pictured) - for cutting and forming wire (end nippers, needle nose, round nose)  
    Some other useful items to have are thin, flexible, clear acetate sheets (for glazing windows), matte clear spray varnish (for prepping parts sheets), and 3M spray adhesive (for laminating card and/or paper sheets together).  3M costs more than other brands, but take my advice, it's worth the money.  Cheaper brands don't coat as evenly and produce clumpier spray patterns.  Trust me -- I learned this the hard way.
     
    I'm sure there's some other stuff I forgot to list, but I'll add those if and when I remember them.  Now, go get your supplies, and we'll move on to the model!

    Hi Nigel, I am looking forward to watching this build, sounds like you have given yourself a lot of extra work, in a good way though!
    The exposed frames between the wales sounds like a nice detail and it will be good to see how you go about creating the new stern.
    Good Luck!

    Doreltomin reacted to Boccherini in Harriet McGregor by Boccherini   
    Having finally completed the Triton x-section, it's time to return to this, my first attempt at a plank on frame scratch build. It is the Tasmanian built barque Harriet McGregor from the plans by Harold Underhill, scale is 1:60. Originally started before Dry Dock Models was in operation, I lost interest in it due to the number of mistakes made in the earlier stages of construction that began to affect the build at the current point. The worst mistake: frame extensions above deck level should have been reduced in thickness prior to the waterway installation. I have done what I can to rectify this without pulling the waterways out (not practical), but will have to live with the consequences and work around the problem, hoping other small details will draw the eye from the larger inaccuracies. Having said all that, the model to date does bear a vague resemblance to the plans.

    Steamship Heinrich Kayser
     
    Introduction to this build log, by Nils Langemann
     
    The steamship Heinrich Kayser was launched in 1898 baptized to its birthname „Elbing“ and was one of the typical new fast merchant vessels built for the D.A.D.G. (Deutsch Australische Dampfschiffahrts Gesellschaft) shipping company at the FSG shipyard in Flensburg, northern Germany. It served the trade route Europe via Cape of Good Hope or via Suez Canal and the red sea and across the Indian Ocean to several Australian Ports together with her sister ships on regulary basis for many years.
    After WW1 and in compliance with the Treaty of Versailles demands the Elbing went under command and management of a british shipping controller, from which the “Elbing” was bought back again by the Hamburg based Kayser & Sohn shipping Company in 1921, which renamed the vessel to “Heinrich Kayser”. In 1922 my grandfather was appointed as the master in command on its last fatal voyage from England to the US eastcoast, down to Florida and back touching Norfolk Virginia as last port and thereafter went down with all aboard her in a heavy full gale and with broken rudderchain and broken hatchcovers. The last SOS radio signals came from position of the New England Seamount Chain, some 500 miles off the US eastcoast where the Atlantic is 5000m deep. No survivers, not a trace was ever found. This type of ship was a mere cargo steamer of 5600 tons, which may have been able to accommodate 2-3 passengers, midships. The Heinrich Kayser was capable of cruising at max. of 12 knots with her twin-boiler arrangement in tandem setup, and having appr. 20 firemen (stokers and heaters), working in shifts to keep the boilers at pressure accordingly.
    I built this model, which is already completed to date, after a shipyard overview plan in honor to my grandfather and all its 43 souls crew and three passengers.
    It is only a couple of weeks ago that per incidence, and 91 years after that foundering, on a raised web forum thread I was able to take up contact with an american lady, who`s great grandmother as well as her great aunt have been on board the Heinrich Kayser at that time and lost their lives as passengers way back in 1922
    The build log shall comprise probably 21 individual parts due to limit of pics per post, and shall document all building sequences in pictures. Comments, questions, etc. shall be welcome and answered along with the build log as it grows.
    The model took me appr. 1800 manhours to build over 2 years including the search for a plan, new modeling techniques like metal- plating /”riveting”, soldering, glass-case making, all trials, etc.
    The fully completed model can be viewed in my album (steamship Heinrich Kayser) under topic : Gallery of completed scratch built models
    Have fun and enjoy whilst studying this oldtimer steamer of 1898 in its buildup

    As work is moving well on the construction of my Caroline build,preliminary work is now starting on my next'bill paying' project.This is based on the Euromodel kit,but it is my intention to push the boundaries of what can be achieved with a kit.I shall be using construction techniques for the hull that have been developed by myself,specifically for this build.The completed model shall include the following details;
    1/hull planking in boxwood and ebony
    2/hull planking omitted between the upper wales with false boxwood frames,this is a feature on quite a few Navy board models which I am quite fond of and an alternative from a fully framed build.
    3/Full hull interior,lower gun deck upwards,with planking sections omitted on the upper decks for viewing the interior.
    4/Remodelling of the stern to replicate the drawing by Van de Velde the Elder.
    This project will be a 'slow burn' until Caroline is finished,but I am starting this log now to avoid missing anything as work progresses.I am trying to avoid starting another log with a planked hull
