USS Cairo 1862 by MPB521 – Scale 1:48 - American Civil War Ironclad - First Scratch Build


Recommended Posts

Thanks for the info Roger. I just finished “Grant Wins the War: Decision at Vicksburg “. Fantastic read. The first chapter was primarily on the northern gunboats and most of those were the City Class “Pook Turtles “. I’ll definitely add that to my list of books to get. 
 

I’m loving my renewed interest in the American Civil War. Certainly more appreciative of it now than I was in my youth.

Hello again everyone,

 

Work has begun on the boiler room walls this go round. 

 

So I finally decided that in order to show the interior of this model, I am going to leave one side partially open and complete the exterior of the other. In order to show some of the details I will also be installing LED lighting hidden behind lanterns and such.

 

I took some ideas from the St. Louis build on how the boiler room walls were constructed. Since none of these walls survived the salvage and the plans are pretty vague on the true construction, builders liberties were taken in my interpretation of them. I installed louvered windows around the boiler walls, under the assumption that these were used for cooling and warming purposes. Air flow from the forward gun ports and funnels mounted on top pf the Hurricane deck was forced down to the gun deck, through the louvers and up through the skylights. Again, this is just my assumption as to how this worked, and I could totally be off base with this.

 

Rough sketched plans of the fore and aft walls used as a template for the louvers.

Not much else was done. I have been dividing my time with other projects around the house, trying to take advantage of a few cooler days. I have some micro LED's and 3-D printed lanterns on order for the lighting, hope fully those will be in some time this week and I can get started on the lighting and wiring.

 

That's all for now. Enjoy, and thanks for the kind comments and likes.

Vaddoc/Don, Thank you both for the kind comments.

 

Vaddoc, these boat were actually fairly sturdy for being built on a short schedule and a shoestring budget. Their flat bottoms, triple keels and heavy framing helped support their heavy armor. Thankfully they only had the western rivers to contend with and not the seas, so they weren't tossed around that much, just swift river currents and enemy bombardments.

 

 

 

Time again for a brief update.

 

While I still contemplate work on my engines, I started working on the paddle wheel frames. I was having a difficult time deciding on what types of material to use for them. At first I wanted to use brass strips for them, but I was having a hard time finding strips of the right size and length. The thickness and width weren't as difficult as trying to find strips longer than 12". While walking around the house looking for ideas, I happened upon the Admiral's sewing supplies. In her spare time she makes face masks for the elderly and donates them to local retirement communities. While I was looking at her her supplies, I discovered the aluminum wire that she uses for the nose pieces in these face masks. This had the correct dimensions that I needed so I borrowed some from her. I did order more to replace hers though, so hopefully she won't be too upset with me.

I then made a couple of simple jigs to wrap the wire in to get the proper sizes for the inner and outer frames.

I started with alternating the spokes, bending them around the rings as I worked my way outward. For the center hubs I found some 1" brass discs and drilled out the centers for the axle.

All of the spokes and rings were held in place with 5 minute epoxy at the cross points. A second disc was placed over the top of the spoke ends and epoxied into place. I again simulated the rivets on the hubs with aluminum tape and my ponce wheel.

Once the pieces were dry they were removed from the jig and the ends of the spokes trimmed off and filed down.

Next step is to drill all of the rivet holes and fill them in with brass nails. That and three more wheels to go. Slow progress, but I'll get there.

 

 

Also this week I received my lanterns from Shapeways and decided to throw one together to get an idea of how it was going to look.

 

Lanterns on the sprues.

The three part that will make up the lanterns. Globe, reflector/base, and micro LED.

The three pieces together.

...and lit up.

Painted up the bases.

Finally one mounted into place. I think I nailed it. I may take a small disc of aluminum tape and put it on the reflector to give it a little better look, I just need to find my hole punch to do this.

Things will slow down for the next couple of weeks, I'm off to Wyoming this weekend for a much needed vacation. Going to attempt to decrease the Antelope population by a few and while I'm up there I'm going to knock off another bucket list item and visit Yellowstone NP.

 

Thanks everyone for looking and all the kind comments.
