USCGC Eagle by mysticlee - Constructo - 1:102

[mysticlee]

I finally finished updating my spreadsheets for the sizes and attachment points on each of the masts and yards, per the Eagle drawing.

 

Besides the detailed dimensions of the masts and yards in the Eagle rigging drawing, two other key measurements are shown.

 

1. Mast rake (German: "mastfall") is specified for each of the three masts: 

 

Fore: 52mm per 1 meter

Main: 70mm per 1 meter

Mizzen: 87mm per 1 meter

 

These convert to 3.0, 4.0, and 5.0 degrees respectively. Now I can accurately set the rake on each of the masts. My estimates based on photographs were in the ballpark, but nothing beats the design specs.

 

2. Standing rigging (wire) rope sizes. There are six different sizes listed on the drawing (50, 60, 70, 80, 90, and 100mm), the largest (100mm) for the fore and main topmast stays, and the smallest (50mm) for the mizzen upper backstay. The diagram also shows that the primary fore/aft stays for each mast are double ropes (which is evident in vintage and current photos).

 

Now, are these figures diameters or circumferences? 

 

The main shrouds are listed as 90mm. If 90mm is a diameter, it converts to 3.50 inches in diameter. If 90mm is a circumference, it converts to 1.11 inches in diameter. Looking at a closeup of two cadets grasping the shrouds, I'd say the shroud diameter is almost certainly 1 inch rather than 3.5 inches (also note that the shrouds are served with small stuff; I'm not planning to model that). 

 

 

Rather than trying to scale and use six different line sizes, I'll use the two most prominent sizes, 70mm and 90mm, for all of the standing rigging. These scale (102.2) to .22mm (0.009 in.) and .28mm (0.011in) respectively, which seem considerably smaller than I would have expected.

 

I'll address the sizes of running rigging later, but the above picture gives a clue as to the size of some of the lines (those pictured are clewlines and buntlines). Note how much smaller they are compared to the shrouds (half or less in diameter). I may need to re-think the scale size of lines for the standing rigging as compared with the running rigging.

 

In any case, I plan to use black line for the standing rigging (rather than dark brown), and tan (or similar) for the running rigging.

 

That's all for now.

Lee,

 

You’re doing a very nice job on this Eagle model.

Thanks, Don, for your kind words. I'm learning as I go, both regarding the myriad details about the ship's rigging, fittings, etc., how to model them, what to include and what to omit. I do a lot of browsing and searching on this forum for ideas and techniques.
