Building a Tenma-Zukuri Chabune (伝間造茶船) – Part 4

Uwakoberi, Koberi, and Iron Nails

So, with the koberi in place, I added the small deck at the bow and the ōtoko at the stern. I’m trying to find out the term for these small decks, which are more like steps. On the Hozugawa boats, the small deck at the bow is called omote-amaose. But, that’s an entirely different region, so I expect the term in Tokyo/Edo would be something quite different.

I also added the uwakoberi, which is what in the west, one would refer to as the gunwale or caprail. Each was made from a single piece of wood, wide enough to cover the edges of the hull planking and rub rail. I made mine a little wider, so that there is a slight overhang on the inboard side.

On tenmasen, the uwakoberi could be quite wide, serving as a walkway for the boatmen. I wanted to keep true to the Funakagami print, so I didn’t go too wide on this. Also, I had a hard enough time putting a bend in the wood. Any wider would have just made this task more difficult.

Building a Tenma-Zukuri Chabune (伝間造茶船) – Part 3

Construction of the model continues as I’ve been working out how I want to tackle some of the details on this 1/20-scale model. The major issues to deal with are the copper mortise covers and other copper detailing as well as the detailing of iron nails used to fasten the koberi, or rub rail, plus wire nails used to fasten the uwakoberi, or the caprails. Some of this is quite simple.

Below, I’ve posted a photo of Japanese modeler Kouichi Ohata’s Tenma-zukuri chabune. He has been helpful in the adjusting of the design of the drawings and has completed a model based on the drawings.

His model is built at 1/10 scale. I may eventually build one at this scale, but for now, I’m happy building mine in 1/20 scale, and I’m considering building other wasen of the Funakagami in 1/20 scale also. It saves on space!

Building a Tenma-Zukuri Chabune (伝間造茶船) – Part 2

In my last post, I discussed the building of a tenma-zukuri chabune from the Funakagami, and I stated that I was working on my model, but didn’t actually talk about building the model. The fact is that I wasn’t sure about what scale to build it at, given that a 1/10-scale model would end up being a little over two feet long, and I’m running low on space to display or store my models. So, I started a 1/20-scale model to see how I’d feel about the smaller scale.

I began by making a temporary internal frame. This would allow me to build the shiki, or bottom, and add the miyoshi, or stem, and the todate, or transom, at the proper angles. The same goes for the tana, or hull planks.

The longitudinal member of the framework is shaped directly from a copy of my plan drawing. The cross pieces are located at positions of the funabari, or beams, and are shaped according to my drawings.

Building a Gozabune (Kobaya) from Paris Plans – Part 12

Work on the Kobaya is moving forward again. While coming up with a way to deal with the decorative patterns on the hull has held me up, I did have some ideas. But, the best I could think to do required the use of a new tool, and it took me a while to bight the bullet and buy it.

Note the pattern of the chain of hexagons and what look like little sunbursts in the Paris drawings.

The solution I came up with was to either create a mask for painting or possibly for the application of gold leaf, or to simply cut a pattern that was itself gold leafed. This probably sounds more complicated than it turned out to be. The central part of the solution turned out to be the use of a vinyl cutter, like those used in scrapbooking.
After looking at a few of the leading models, I finally made the leap and bought a Silhouette Cameo 3. I found one for about $200 online and spent another $150 or so on materials and accessories.
The closest competitor to this was the Cricket Maker, but it was more expensive and the drawing software was only usable online, requiring an internet connection to use. Having Internet is not an issue, but requiring it to use my own hardware or even to create drawings was not an idea I like supporting.
I was able to test out Silhouette’s drawing software for the Cameo, which was available as a free download from their website. That allowed me to determine that I would at least be able to create drawings of the things I needed it to cut.

Building a Tenma-Zukuri Chabune (伝間造茶船) – Part 1

I completed what I believe is a good final draft of the Tenma-zukuri Chabune from the Funakagami, and I’m now working on my model. However, it appears that I am already late to my own game. Model builder Kouichi Ohata has already completed his model in 1/10 scale, and he’s done a beautiful job with the boat as well as with all the added details!

Kouichi Ohata’s model

With the help of fellow modeler Kouichi Ohata and my mentor Douglas Brooks, I’ve gone through several revisions of the plans – seven major ones, so far.

The biggest difficult has been in analyzing the single wood-block print of this type. Compared to other boats in the Funakagami, this one has a very flat bottom, showing no real rise at the stern, which may be possible, but it’s really throwing people, as it seems very unusual for a Japanese style boat.

Building a Gozabune (Kobaya) from Paris Plans – Part 11

A yakata for the kobaya?
I’ve been looking at the yakata, or deck cabins, on the paintings of kobaya. Also, there is one from a larger gozabune that was removed and restored and on display at the museum at Kumamoto Castle. I’ve been in touch with ship modeling colleagues in Japan and they told me that it is from a ship called the Naminashi-maru (波奈之丸).

I’m still very confused about the dimensions. To me it looks very low, but I’m told the lower level is 1.7 to 2 meters high on the inside. Part of this, I assume is because the floor is below deck level, which is the case on my kobayabune.
To aid in design of the yakata, I’ve fitted a removable cardboard structure. This gives me a sense of size and appearance. I can’t really add the structure without the attendant framework over the whole ship for an awning.
I drew in some outlines for sliding doors and a railing atop the structure. Apparently, the passengers would also sit atop the structure. I’m not sure how they would climb up, but I’m assuming it would be with a “leg up” from one of the attendant samurai on the deck.

Building Woody Joe’s 1/72-scale Kitamaebune Kit – Part 4

After some early troubles with the hull construction, the model has been coming along very nicely. With the addition of the outer bulwarks fences, I began my next modification of this kit. The main deck of the sengokubune (the common term for this type of ship) has a pair of gates which are removed to allow easier loading and off-loading of cargo. On this kit, the inboard part of the bulwarks is a solid sheet of wood, with no indication of such a gate. So, I took my Japanese razor saw and cut openings for the gates.

I then lined the base of these opening with a sill of sorts, and then used the cutaway sections and glued them into place so that they were more clearly gates. Completing the outside of the bulwarks fence, I decided to add one strip of molding just above the main rail as a continuation of the one on the gate. You can see this in the photo below. The left arrow shows the one on the gate, which is part of the kit. The three arrows on the right point out the strip that I added. It’s not necessary, but further differentiates my model from others. Continue reading

Building Woody Joe’s 1/72-scale Kitamaebune Kit – Part 3b

This is just a short update on the Kitamaebune build.

I added a couple pieces to the transom to simulate the plank that seems to show up on every benzaisen model or image I’ve seen.

In the above image, the red arrows point to the plank that I’m referring to. The blue arrow points to the very tip of the side planking at the stern. The piece in the Woody Joe kit is truncated close to where the dashed blue line is, and actually a bit lower than that, really.

Building Woody Joe’s 1/72-scale Kitamaebune Kit – Part 3

Now is the time I find out how I did in the earlier steps of construction. The biggest challenge of kits with laser-cut parts, particularly hull planking, is that if you don’t get it exactly right, you end up with gaps or parts that don’t fit quite right. Even worse, it’s a sign that something else is off and may cause you more problems down the road. You just have to consider it a challenge.

So, the next steps involve adding bulwarks pieces that contains holes for all the beams. These nicely aligns all the beams. There are two pieces for each side of the hull that fit together end-to-end, with a neat, pre-cut scarf joint betweent. The diagram in the instructions, makes it look like you’re supposed to glue the pieces together, so you have one full-length piece for each side, but don’t do it. You’ll have problems fitting the pieces into place over the beam ends and, in the process, the glue joint at the scarf will likely pop loose. As with all hull planks and such, it’s always a good idea to wet the pieces and bend them to shape prior to installation.

Another tricky part about installing these pieces is that they need to fit flat against the first bulwarks sheets that were installed earlier. Not a big deal except at the stem, where the glue joint between the stem and the very thin bulwarks sheet is pretty weak. If you apply any pressure while trying to get things to fit, this glue joint may fail. I’d suggest using a heavier bead of glue, but I believe this area inside the model will be visible when completed, and the glue will probably show up well.

I don’t have a good photo of this step, so I used a later photo and added arrows to illustrate the position of these pieces.

Tenma-Zukuri Chabune (伝間造茶船)- Plans Reconstruction Update

Work on the drawings of the Tenma-zukuri chabune continues. Over the past months, I’ve been making changes to my drawings of this wasen that I found in the the Funakagami. With the help of fellow modeler Kouichi Ohata and my mentor Douglas Brooks, I’ve gone through several revisions of the plans – seven major ones, so far.

Compared to other boats in the Funakagami, this one has a very flat bottom, showing no real rise at the stern, which may be possible, but it’s really throwing people, as it seems very unusual for a Japanese style boat.

Also, if you look at the near side of the boat, particularly the bottom, it doesn’t appear to show any inward curvature. This threw me initially, as this is, again, pretty unusual. It’s not impossible, as the hozugawa boat I built doesn’t have any inward curvature at the stern either. But, looking more closely, at the far side, you can clearly detect inward curvature at the stern. The lack of curvature had bothered some people, so I’m glad I could spot some in the image to justify it on my drawings.
