    Roger Pellett reacted to mysticlee in USCGC Eagle by mysticlee - Constructo - 1:102   
    Below shows the first few test turnbuckles, as yet unpainted (they will be painted white in production). The body is a short piece of 1/32"diameter brass tube. The eyes are formed from 26 gauge brass wire, which fits perfectly in the tube. I created a small jig (two small posts) for wrapping the wire to create the eyes. The eye on one end will be open initially, so that I can slip it onto the existing eyes fastened to the deck, rails, and other attachment points, then the eye will be closed. The standing rigging will then be tied to the free end of each turnbuckle.  I found it a bit tricky to cut the brass tube. I rolled the tube on a flat surface, and used a #11 scalpel blade to score it. The blade tends to wander under too much pressure. I'll need to refine my technique before mass producing these turnbuckles.

    Planking the bow.
    Purely speculative. As mentioned earlier, the planking here is horizontal, on many carracks it is curved vertical, but at the time of the sinking of Mary Rose this seems to have become somewhat old-fashioned. most drawings then show horizontal planking.
     
    First, a clean up on the inside

    Then the bow is built up step by step.

    The bow is planked. Not clearly visible in the photos, but there are still depths and heights in the shape here and there. But the planks are thick enough to sand away these imperfections.
     
    And. Not happy with the errors on the right, but we don't see anything about this later. Needs further sanding (left)

    With the cardboard fore castle. In this setup the height is already 1.5cm lower.
    Next, sanding, applying treenails, etc. to be done.

    Thanks for following

    The photo below is the slipways at Hillman Barge and Boat in Brownsville, PA where we had the mishap.  This photo was right after a successful launch as the barge and catch boat can be seen on the right.   Googling photos of the yard like the one I found below brought back some really nice memories.

    Dravo’s Neville Island yard used much the same setup.  Of course, the width of the yard’s waterfront could a bottleneck in the mass production of these simple vessels as it restricted the number of launch ways that could be built.
     
    To overcome this Dravo had a setup where barges and towboats moved across the yard sequentially until the completed vessel reached the launch ways.  I would assume that other River yards used the same system.
     
    I always thought that I would have liked to work at Dravo’s shipyard, but instead they wanted me at their Pipe Fabrication Division.  In the end, I was lucky.  The shipyard closed in the late 1980’s but the Pipe Fabrication continued into the early 1990’s.  By that time I had a new job here in Duluth.  I did see the yard side launch a barge- Big Splash!

    The famous Great Lakes Steamship Edmund Fitzgerald that was over 600ft in length was launched sideways.  So were the rest of the 600ft+  Great Lakes vessels built in the American yards in the 1950’s.
     
    Drydocking a ship usually requires a “docking plan” prepared by a Naval Architect. This shows the arrangement of the supports in the dry dock.  The support structure can be checked by conventional surveying methods before the dock is flooded to receive the vessel.  Any irregularities in the dock floor can be allowed for at this time.
     
    I’ll check my copy of the Iron Ship this PM but I believe that Great Britain was built in a specially built dry dock.

    Piping has a certain logic.  High point vents, low point drains, bypasses around some eqipment and valves, and loops to absorb expansion and contraction in long runs.  There are industry standards for fittings like elbows, tees, flanges, etc.  Long Radius ells are formed to a radius of 1.5 nominal pipe diameters, eg a 4in nominal sized elbow is formed on a 6in radius although the outside diameter of the fitting and pipe that it welds to is 4.5in.  Metric pipe sizes while specified in metric dimensions usually correspond to American pipe sizes.  Pipe bends are usually specified in nominal pipe diameters too;  3 dia, 5dia, etc.  Unlike fittings, which are purchased from a manufacturer, bends would be made at the shipyard or by specialized pipe fabricators (where I worked for most of my career).

    In areas with large tidal ranges there were special dry docks used for building ships.  
     
    In 1940 Great Britain contracted with the now famous “7 Companies” that built Hoover Dam to build 60 badly needed, large for the time, merchant steamships in the USA.  Since American Yards were busy, the deal included building two new shipyards; one on San Francisco Bay and another on the East Coast in Maine.  Conditions in San Francisco Bay, including tidal range were such that conventional sloped launch ways were quickly constructed.
     
    The large tidal range in Maine required construction of dry docks.  The need to blast these docks out of Maine’s granite delayed the construction of these East Coast  Ocean Class ships by several months.
     
    Ships on the Great Lakes built prior to the 1000 footers were traditionally launched sideways.  The smaller Navy Combatants being built by Fincarii Marine in Wisconsin still are.  The 1000 footers were built in a dry dock.

    What a great project!
     I too grew up reading Paddle to the Sea.  I loved the book.  35 years ago I was fortunate to be given the opportunity to move from the Ohio Valley to accept a new job in the Great Lakes region and I accepted it in a heartbeat.  I can just barely see a tiny sliver of Lake Superior from a window on the second story of my house.  I also made sure that my children grew up with the book too.
    Did you know that there is a Paddle to the Sea movie too?  Here in Duluth the Army Corps of Engineers runs a nice museum dealing with Lake Superior.  During the summer tourist season they show movies about the lakes in a conference room.  Visiting with my two kids and my granddaughters the announcement came over the speaker that there had been a special request from a family visiting to show Paddle to the Sea.  My daughter had made the request.  The movie while beautifully filmed cannot reproduce the 1940's picture of the industrial lakes that Holling does with his book.

    Nils, thanks for that. I had forgotten about the 'Padua', but she is in many ways a similar ship.
     
    Jerome, this restoration is a little different to most, as we want the model to accurately represent the ship at a particular period in her history. While we are keeping as much of the original work as possible, some has to go in the interests of accuracy for a museum model.

    A while ago, I bought  a set of broaches on Amazon, Made and shipped from England.  They are triangular files without teeth. The smallest is about 1/32” and the largest 1/8”.  They would work for truing up your holes.  They would be less aggressive than than files.

    Just a small amount of progress to report. May is not cooperating in terms of free time to work on models. 
     
    I added the longitudinal hog chains based on some blurry historical image details and logical assumptions about their natural location. I used thin wire, which I couldn't get perfectly straight, but it's another quirk that the camera captures but the eye doesn't really see.



    Then I got to work on the...not quite sure what to call them, but the timber frames on the bow used to push tows. You can see them pretty clearly here:
     

    This is where I found I hadn't thought ahead enough. Those are pretty widely spaced across the bow, which means the bow has very little curvature. When I went to install mine after making them, I found that my bow curves away more sharply than I thought when I first laid it out, so now if I placed them that far apart their fronts fell well behind the bow and wouldn't be able to push anything. 
     
    So I had the choice of either placing them accurately far apart, but too far back from the point of the bow, or too close together, but accurately forward enough to extend just beyond the bow. For better or worse, I chose the latter, though now I'm wondering if it was the wrong decision because they're more noticeably "wrong" compared to the original photos than if they were properly spaced but a bit too far back. Anyway, see what you think (compare to same photo angle in background):

    Another view, with comparable angle in background and separate photo below:
     


    Changing them would mean popping them off the deck and hopefully not leaving too much glue stain; I could always cover those with a few random timbers or something. Thoughts?
     
    In the above photos, you'll also notice I built a version of the capstan that sits just behind those whatever-they're-called braces.
     
    Finally, I added the two thick diagonal braces that lead aft from the chimneys to the pilot house:

     
    I think I'm getting close to done with the basic details. There are some more thin guy wires supporting the chimneys, though they're very hard to see in the historical photos. I need to figure out where I'm going to get that big locomotive headlight that's so prominent on the front edge of the boiler deck.
     
    The biggest single project remaining is the paddlewheel, which I'm going to need some quiet focused time to concentrate on designing. Not going to happen in the next week, that's for sure. But I started this log on June 17, 2023, and there's an outside chance I'll have her done one year later. Thanks for sticking with me!
