Building a Himi Tenma in 1/10 Scale – Part 5

Since we’re still under the stay-at-home order and I have time, I’m plowing ahead with the Himi Tenma. I did manage to get some measurements from Douglas Brooks, but mostly, to verify that my beams are fairly close. Not all exactly like the boat built last Fall, but close enough for this project.

With the beams, or funabari, in place, I went ahead and added the decks at the bow and stern. I don’t recall off hand what the term is for the stern deck, but the bow deck is called the kappa. I fit both decks by first making a templates that I cut to fit as best I could in place of the planks.

I cut three planks to make up each of the decks. For the stern deck, I installed a simple strip of wood onto the transom, or todate, to serve as a shelf for the lower plank ends. That wasn’t necessary at the bow, due to the shape of that deck, which held the planks in place better.

The aft deck turned out well, but I realized later that the bow deck angles downward too much, and is probably smaller on the actual boat. But, it looks fine and I don’t really think there’s any need to redo it.

Building a Himi Tenma in 1/10 Scale – Part 4

I started working on planking the hull of the Himi Tenma shortly after my last post. The first thing to do was to cut a cardboard template to the approximate shape of the hull plank.

This was done by taping a piece of cardboard into place on the model. The bottom edge was traced with a pencil onto the cardboard. The shape at the bow was approximated, and the stern end was cut off a little bit long. The top edge was derived by marking the top edge at the ends of the model. I then used a thin wood batten to create a fair curve and traced that shape onto the cardboard template. The template really does not need to be very accurate. It just has to be big enough to work, and a bit oversized is best.

The template can now be used to help select the wood. I try to be efficient as possible and  find a way to get two planks out of the smallest sheet of wood that will work, since the wood I’m using is hard to come by.

Building a Himi Tenma in 1/10 Scale – Part 3

I’m making decent progress on the Himi Tenmasen model and am now working on the kanjiki planks. These are the bottom planks located either side of the heavy, central bottom plank, called the chyou. As I mentioned before, my model will have two kanjiki planks on each side, much like in the tenma drawings, though the boat built last fall actually only used one plank per side. But, this way allows me more efficient use of my wood supply, and if I screw up a plank, I lose less wood. And, while it means more mortises to cut, it also means there is more detail on the model.

Measurements of mortises given are at full size.

Building Woody Joe’s 1/72-scale Kitamaebune Kit – Part 11

Sailmaking is at somewhat of a standstill, as I’m experimenting with different techniques for representing the large sails of the kitamaebune in 1/72 scale. There are number of possible things I can try,, including simply stitching the seams as one might do for a western ship’s sails, but I’m still hoping I can show some of the characteristics of the Japanese sails.This is something of a long term process, so in the meantime, I decided to move ahead with some of the other model details.

One of my sail making attempts still being tested and considered.

It had occurred to me that might make the most sense to go ahead and build the various components of the main stay. It took me a while to figure out this is called the Hazuo in Japanese.

Dealing with the stay, or hazuo, requires making/rigging four different parts. Here’s the section of the instructions that deal with this.

Building a Himi Tenma in 1/10 Scale – Part 2

Reviewing photos of the Himi Tenma that Douglas Brooks worked on last Fall, I’ve been comparing them with the drawings from the Himi City Museum. There are a number of differences which I’ve marked on a copy of the drawings.

Modified copy of the Tenma drawings provided by the Himi City Museum, shown here with permission of the Himi City Museum.

To match the Himi Tenma built last Fall, the features that I’ve marked with red arrows will need to be omitted from my model. The blue rectangles represent the approximate size and location of beams which will need to be added to the model.

In addition, the other main difference is that if you look at the frames in the drawing, they are offset so that the starboard frames aren’t directly across from the port side frames. However, in the boat built last Fall, the tops of the frames actually sit directly across from each other, but since the frames still overlap one another, they are canted slightly. For now, I’m just making a mental note of these things, and will deal with them when the time comes.

“Fune” Build by Alexandru Gurau

Years ago, ship modeler Alexandru Gurau of Canada had been building a model of a bezaisen, an Edo period coastal transport, based on drawings recorded by French lieutenant Armand Paris, and recorded in the book Souvenirs de Marine.

I was particularly impressed by Mr. Gurau’s work, as the information contained in the Paris drawings are a bit difficult to follow on their own. My own experience with the building a model from Paris drawings resulted in my own Kobaya project. In that particular case, I had discovered that the drawings may have been somewhat incomplete as they were based on vessels that were no longer in use and seemed to be missing features. I believe that problem was unique to that particular vessel, and the other Japanese boats recorded in the book appear complete. Still, not always easy to decipher all the information needed. Not to mention that the note contained in the drawings are handwritten in French.

Still, for the larger subjects in particular, like Mr. Gurau’s Fune model, It just seems difficult to wrap one’s head around the details due to the unusual nature of the hulls of these coastal transports – unusual to the western eye, anyway.

Scan of what Paris describes simply as “Fune”, recorded at Kobe, Japan, in 1868.

The Mr. Gurau’s model was mostly completed in 2013-2014, but he recently updated some things, which brought the model back to my attention. His dealing with the sails of the vessel have given me new inspiration to complete the sails of my own kitamaebune model, which is based on a kit from Woody Joe.

His build photos are available to view on his personal ship modeling website here:  http://www.alexshipmodels.com/2016/10/28/fune-build/

He also documented the build on The Nautical Research Guild’s Model Ship World (MSW) online forum here: https://modelshipworld.com/topic/3230-fune-by-alexandru-finished-japanese-ship-of-1868-scale-150/#comments

The one thing to note on the MSW forum’s topic title and first entries say that the model is built at 1/50 scale, but it appears that his model was actually built in 1/100 scale.

In any case, it’s nicely done and worth checking out. Ω

Building a Himi Tenma in 1/10 Scale – Part 1

You might recall that In the Fall of 2019, boat builder Douglas Brooks had developed a project together with Nina Noah of an organization called The Apprenticeshop, to go to Japan and build two traditional Japanese boats with two different Japanese boat builders.

I wrote about modeling the first of the two boats, the Niigata Honryousen, which he had built with Mr. Nakaichi Nakagawa and Nina Noah. But, it’s the second of the two boats that was the main subject of the project. The second boat was the Himi Tenmasen.

The Himi Tenmasen, or Himi Tenma, was built by Douglas Brooks and Nina Noah, under the guidance of Mr. Mitsuaki Bansho, a Japanese boatbuilder who was the only one of five brothers to follow in his father’s trade, who was also a boatbuilder. After his father’s passing, Bansho-san primarily built fiberglass boats, but in the past 20 years, he began building boats in traditional Japanese fashion for museums.

The Himi Tenmasen is a typical small boat that was used in fishing and as a general workboat. Similar types were used to ferry cargo and passengers between larger ships and the shore.

Building the DNB Maru – A Niigata Honryousen – Final

The Honryousen model is done and been sent to its new owner in Washington state.

The blocks at the ends of the hull turned out to be somewhat challenging to make due to a combination of the way they fit notches cut into the hull planks, plus the angle of the tateita, or the bow and stern planks. Also, the blocks have a peak in the center that look best if they are roughly level with the waterline. That’s not always the case in these types of boats as I’ve seen in photos.

The small deck at the stern wasn’t too much of a problem. I began by making a funabari, or beam, which I notched into the hull planking. As there are no fasteners used, the shallow notch I cut was helpful in holding the beam in place. The inward pressure of the hull planks also help to hold it in place. I used a small amount of carpenter’s glue to help secure it, just for good measure.

Building Woody Joe’s 1/72-scale Kitamaebune Kit – Part 10

I’m now in the final stages of the building of Woody Joe’s Kitamaebune model kit. I’m working on the sails and rigging and dealing with a few small remaining details.

The kit sails are very nice, and have the sail seams and lacings printed on them. From a normal viewing distance, they look great, and I’ve gotten compliments from those who glanced at them and thought I’d stitched them. But, I’m going to need a main sail as well as one at the bow and I want them to match. The only way to do that is to make them both.

The big issue is that I’d love to be able to detail the Japanese-style sails, which are made of separate panels that are laced together. The design is such that the sails are effectively self-reefing, so that they spill the wind when it gusts. This design is more apparent on sails of smaller vessels, and I don’t know if the lacing between all of the panels are that way, or just between the four large groups of panels. But, you can see the idea in a pair of photos from ModelShipWorld member marcjp, who lives in Osaka, Japan, and took these photos of the museum ship Naniwa Maru.

Building Woody Joe’s 1/72-scale Kitamaebune Kit – Part 9

I’ve finally made significant progress, though most of it doesn’t really show, as so much is in the small details – the simulated copper coverings are finally done!

This took me a while as I kept thinking I was done. Then, I’d think some more and realize there was some other feature I wanted to add. I’d no sooner finish that, than realize I really should add yet another feature. This cycle has repeated itself many times, but I think it’s over now, and I can put that equipment away.

The next item I decided is pretty straight forward and related to the vinyl “coppering” details. Often times, the coastal transports, known generally as bezaisen, are shown with nail heads in the bulwarks fences. Adding these at this scale may be a mistake, but I’ve started down the road – No turning back now. I drilled out all the necessary holes which will be plugged with some 22 gauge copper wire. I intend to blacken the wire using liver of sulfur.

Holes were drilled out and I started the process of making copper “nails”. The heads have to be flat, so I filed the end of the wire and then cut the “nail” off.
