Being a little lazy lately. The Admiral has kept me busy elsewhere. But, I still had some time to test my micro soldering. Still not very happy with the results but at least I found a good technique to use. Following are the photos of my set up and the result on micro door handle. Also, some progress on the boiler. Hinges and latches come next. Wife gone on a safari in Borneo. That will give me a little more time to play. LOL

I have been working on the valves with some success and finally fabricated an acceptable mini valve. Started with a much larger rod then ordered the right size (3/16") but had difficulty with the cutters in the lathe. Decided to fabricate the valves in a mass production cutting each valve in series so I would cut the body leaving the thickness of the flange and the cut another body etc. The result was a with a series of flange-body-flange-body-flange........... Unfortunately I didn't take a picture. When I finished the series I took it off the lathe and went to cut each valve apart. Guess what, the distance between bodies was only one flange thickness. I had forgotten to make the series as "flange-space flange-body- flange-space.....". So I started again and this time I did it correctly. I used tacks for the stem and handle and this how the unpainted valves look. Thanks for following.

Wefalk, you never cease to amaze me with your micro work. Thanks for being such an example to us plebes.

I was itching to start work with the lathe and, I was also figuring out the piping of the boiler/engine system. Right at the start I noticed the large number of valves that would be required. I counted a minimum of 15. So, I am going to bring up the lathe and start making these tiny valves. The fun starts now. Lathe setup. Drilled the stock to the pipe size, and then machined the body. Then I will cut a disc and attached it to the body with a proper size stem. On this valve I started with some old 3/8" rod stock. But now I found the 3/32" rod that will make the machining easier. Stay tuned.

Valeriy, I used brass mini nails that are sold by Micromark in the US. These nails are sold to temporally fasten planking strakes in the model frames. I have a supply of them. They have round heads and I set them on holes filled in the door but leave a little of the stem out. I also used other sizes using sewing pins. Now I am trying to figure out how to made the lever type door knobs to use on the other doors of the model. Thanks for your comments and likes. Any ideas?

Completed the rest of the superstructure. A few little details were left out since I am anxious to start building the propulsion system. Dry fitting all the parts, I assembled the ship. Then, started work on the boiler. First, the smoke box. Then the stack. Followed by the boiler. And this is the dry fitted boiler. I have also been following Cathead's build of the Peerless. Very interesting and informative. As a mechanical engineer, whose work was mainly in the energy systems, I enjoy the debates about insulation, expansion loops, superheaters and steam traps on the piping. But at the scale I am working it is hard to include all the minuscule parts that would make the piping correct. Thanks for watching and I enjoy your comments.

calt4, welcome to my build. It is a lot of fun to scratch-build a model. In addition to figure out how to fabricate a piece you also have to figure the right sequence for the assembly is also important. For instance, in this model, I assembled the walls of the cabins and then have to open the windows on the finished cabin. It would have been easier to build each wall independently and then assemble when completed.

Little more progress. I didn't like the way the passenger cabins came out while using plain walnut strips as shown in my previous post. According with the information I had from the article in Model Boats, these cabins were built in mahogany; so, I bought already scribed basswood boards and fabricated the new cabins. I used a mahogany stain and the results can be seen in the photo, shown here on top of the planked boiler deck. I used the same type of pre-scribed board to do the main deck and the boiler deck planking. I also developed a method to make the windows. Basically, I drew the them in card stock and glued the minute frames to the cardboard and then cut the opening. The window was cut oversize from the card and glued to the opening in the walls of the cabin. You can see the the card stock in the inside walls of the cabin above. The window glass (acrylic) will be attached to the inside of the frame. I used a similar method to make the varios doors. The finished doors will be glued to the outside planking in the cabin. Forgot the scale match but the window is 12 mm wide. The doors had a similar treatment. Completed the planking in the main deck. Have already finished the roof but have no pictures yet. Getting closer to the mechanicals.

A little more progress. Painted the hull and completed the lower cabins. Getting ready to start the main deck planking. Had a little trouble with the main cabin in the boiler deck. Have tried several methods to display the mahogany planked walls using very thin strips. The results don't look good since the grain shown is so apparently out of scale. Decided then to fabricate the cabin using striped basswood pieces.

About the NRG
If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.
The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.
The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
