D51-200 Tender Locomotive 2-8-2
« on: April 13, 2019, 04:07:44 PM »
It is with great pleasure that I begin the construction of this iconic Japanese locomotive with the support of the membership - with the understanding that it is a pre-machined model of steel, brass and die-cast metals.

The class D51 2-8-2 engines were built in Japan mainly, but other countries as well, from 1936 to 1945. D51 200 has been preserved in operational condition by RJ West at Umekoji Steam Locomotive Museum in Kyoto, and has been operating on Yamaguchi Line since November 2017.

The kit is very well organized. When it was originally sold, the intention was that it be shipped to the customer one month at a time - cost being a factor. Now the kit can be purchased all at once. I was rather shocked when the delivery van pulled up loaded with boxes.

Here they are in the front hall.  :o

Let's have a look into box one.
I am very impressed wtth the way things are organized. Every part has its own plastic well in a vaccuum formed plastic tray. Even the bolts are lined up in rows and set into the tray vertically.
The first box has a DVD (in Japanese) and a very clear information and construction stapled booklet.

Thanks Kim.

You agreed with me about how well the parts are presented. Here is visual proof of that.  My finger is pointing at 10 2 x 5mm screws standing like little soldiers in their specially formed well.

Quite Impressive I think.  :ThumbsUp:

I visited that museum in Kyoto a couple of years ago.  One of the best railroad museums ever.  I also went to the one in Saitama, a 45 minute train ride from Tokyo.  Also excellent.

As anticipated, this does look as if it will be quite a fascinating kit build, and of an unusual prototype for most of us. The packing and presentation is very fastidious, to say the least, but you must have been mighty surprised to see the pile of boxes that will produce a loco , what? about 33" long?  when assembled...!   All looks pretty exciting..   Dave

Hi Chris,
 Good observation - it does have a nice balanced look.

Hi John,
 Me too.

Hi Kvom,
 Thanks for sharing. That must have been a wonderful visit. This D51 200 was built in 1938 at the JNR Hamamatsu factory. It's 19.7 m long, weighs 125.1 tons and has a maximum speed of 85 km/h.

Hi Dave,
 Good guess. In 1:24 scale it's 34.65" long. When finished, it will weigh 22.9 lbs.

The first part I've made is the sign for the smoke door.It carries a lot of information. The first letter indicates the number of driving wheels; D means four smaller driving wheels, C means three larger driving wheels. (There is a C57 kit available from this company as well)  The 50 to 99 numbers means the coal and water are carried in a tender. If they were 10 -  49,  the locomotive itself carries the coal and water. The last three numbers are the serial number of the engine and in this case means it was the 200th D51 that was made.

Oh what you can learn from the internet!  ;)

Yes fellows, the care given to the packaging and documentation speaks volumes about the quality of this product.

Some fellows like a brass engine. I am not one of them. This means more time has to be spent planning assembly and waiting 24 hours for a primer to dry.

Serious assembly begins with the smokebox and smokebox door with operating hinges. The brass tube was overrolled so that when it was pulled back to a circle, its seam snapped tight around the boiler ring.  :ThumbsUp:

I made a jig so that I could rotate the tube as it was being primed. The first coat was applied last night; the second 'dry to the touch flat finish'  was photographed this morning.

Priming and Painting
« Reply #16 on: April 15, 2019, 09:27:56 PM »
I can question only one thing about the sequential instructions for this project. I jumped the gun and went to the last booklet of instructions. Book twelve raised the option of leaving the engine brass or painting it. The very last booklet!

Instructions were given to spray a little bit of paint into the cap of the spray can and use a very tiny brush to get at parts difficult to access with the spray paint.

I take issue with this. In my view every part should be carefully thought out, primed and painted as the construction progresses. That approach will be used as the engines develops.

This probably doubles the assembly time, but isn't this a hobby where time on the project is fun and enjoyable?

Just my thoughts.  :old:

The Spark Arrester
« Reply #18 on: April 16, 2019, 02:58:15 PM »
While the primer is drying on the chimney, I have assembled its spark arrester. It is made of 5 pieces and has a cone shaped brass mesh and a smaller mesh section below. They are soft soldered.

This attention to detail is impressive. It's one of those parts that nobody sees, but the builder has fun making them and knowing they are there.  :D

In this case, the smokedoor can be opened to see it, but in reality, who is going to do that when the model is finished and sitting proudly in its display case?

It will probably be painted an ash grey.

Yes, a beautiful part.

I have changed my primer. After consulting with an expert, I went back to an etching primer that has a better potential of grabbing the brass. Apparently even so, brass will eventually eat its way out through anything you attempt to put on it. It's just the nature of the metal - it gives something off from within itself.

On to some other interesting parts. I am holding a pre-drilled ball shaped brass stanchion. Very nice. Handrails already rolled to the correct curve fit into those holes.

This smokebox is almost ready for a second coat of primer.

Thanks Bill.

The smokebox is developing nicely. Some. parts such as the nameplate, light lens, door locking wheel handle and locking lever can not be applied to the model until after it is painted. It's kind of frustrating, beause you want to see what things will look like now!

The light diode is in place behind the masking tape. It could be months before I test it to see that it works. I have read that some fellows have had some difficulties with the electrics.

Time will tell.

The Lens
« Reply #23 on: April 18, 2019, 09:27:20 PM »
Speaking of that lens. It is not simply a flat piece of plastic. It is made of plastic, but it is striated and has radii like a real lens. It looks as though the center section with a different radius may focus the light as an actual lens of this sort would do.

Hi Bill,
Agreed.
The only bit of machining I have had to do on the first stage of this build is drill oil holes in the oil boxes on the coupling rods. On the real engine, I would think there would either be an oil cup (capped)  or a grease fitting attached there.

This concludes stages 1-8 of Pack 1.
Completed (almost) are:
The smokebox, chimney, feedwater system, first drive wheels with coupling rods and the front deck with its maintenance hatch and lamp hooks.

I do not understand the function of the release lever.

Do you mean the lever on the pilot beam? If so the lever lifts the pin on the Janney style coupler, to allow the laws of it to open and uncouple the cars.

Great job on the assembly so far! Looks like a beautiful kit.

Steps
« Reply #28 on: April 21, 2019, 04:44:31 PM »
Thanks, but I'm not sure we are talking about the same bar. In the photos a light steel rod with a handle in the middle has two hooks on each side. Surely they do not fasten cars together?  :o

Pack two begins with steps on the front and at the sides of the front deck. By comparison, the third photo of an American engine shows elaborate steps and raiings. But on the Japanese  D51, simple steps suffice. The lower steps are actually set into the inspection doors.

I think CNR is correct, it would lift the pin in the coupler, releasing it. The rod itselft does not take any strain, its just a control lever.

Good looking stuff there John. I think, if you cheat and look ahead to where the couplers go on, you will find something that will go from the middle of the long bar, straight down to the pin in the coupler. Moving the pin up, unlocks the coupler.  All will be revealed! From the level of detain shown so far, I don't think they will leave that bit out.

Cheers

Just looked again at the picture of the front assembly, that loop in the middle is where the link or chain to the coupler pin attaches, as the loops at the ends are pulled up by hand that would raise the center loop to pull the pin.
Amazing amount of detail in those parts!   :popcorn:

Ah, now I understand. Thanks fellows for the info and thanks Chris for the photo. Yes, there has to be a way to pull that pin.

I am fortunate to have such kind mentors.

I am coming into some interesting terminology now. I know some of the terms, but I will learn as I go with motion bars, valve tail guides and such.

The rivets in these two pictures do indicate the level of detail. They are 2mm long and although cosmetic, all 16 are real.

Thanks Chris.

Yes, a diorama like the ones you suggest woud be wonderful. However, this engine is too long!

Also, I have chosen to display it in a showcase designed specificaly for it. Actually Chris, the base of the engine has four switches on it. So it is purposely designed for singular display. The motor in the engine runs the train in place on ball bearing wheels set into the track.

This photo shows M2 x 2mm Phillips screws for fastening parts. I don't think a Phillips headed screw was ever envisioned in the time frame this engine represents. But they seem to have their appeal nevertheless. They will probably blend in better when the engine is painted and topcoated.

Piston Rods

For some strange reason, the kit provided 5/32"brass piston rods.  :shrug:

They were discarded and replaced with steel ones. I made the front dummy extension rods myself from 3/16" soft steel, but bought some 5/32" drill rod for the rear rods that slide in the cylinder.

Hi John,

I'm happy that you are enjoying following along with this build. Although I havent made the parts, I'm  thoroughly enjoying assembling them.

I am beginning to downsize my shop due to health issues. I have sold my General 160 wood lathe, my 13" thickness planer and my floor stand drill press.

Time to think of the future.

This photo shows my principle workshop now - my model desk!  :Lol:


I still have hopes of finishingf that Lincoln double cylinnder stationary mill engine for the unfinished diorama, so the metal lathe and the milling machine remain.
