Dora 1/35
1 Attachment(s)
Hi to all, here is my next project, the massive Dora kit. I always wanted one since I saw the add on the pages of finescale modeler, but the price was too high. Then it got even more expensive due to its shipping weight. Finally after 8 years my dream came true, I Got it for $560 including shipping from Germany and Here it is, 35+ pounds of plastic, 3200+ parts including PH and aluminum rails.

I’m a happy modeler
Compared to a tiger box
Also have the excellent book by Mr. Taube for reference, the decals from peddinghaus
And the aluminum shells from Mr. Schatton
Here the giant shell compared to a trumpeter figure body
Opening the big box you encounter the instruction book and five boxes numbered 2-6.
Each box has its number and the information of the bags inside and the parts inside each bag
Here are some of the boxes and its parts, all the boxes are full to the top
And the bag of screws
Each bag has all the info on its contents and the box it belongs to
So the work started by fixing one of the mayor problems on the kit, the cars, they did 4
Long cars instead of the 8 smaller cars that Dora had. It will be impossible to turn in a real radius with the cars as they come. So to fix it you have to cut the cars in half ending
With 8 five axle cars, two for each end of the main mount.

Here the sides and top parts of one of the cars ready to be cut

After all the parts are cut it looks like this
First you cut in the center, then cut again each side to approximate 2-3mm to compensate
For movement.
Then I removed what is left of the ring from each half and sanded the area smooth

Next is the assembly of the brake system and wheels, its a million parts for this area
All the sprues for the brakes and wheels
80 wheels and 40 axles
And all the parts cleaned and ready to install

That’s all for now as soon as the cars are ready I will post the photos
Thanks for watching

Damn, it's too big! )))

Fledermaus 06-17-2015 12:00 AM

Hi Andrey, yes it is a very big kit almost 2.5 feet longer than the schnellboot :eek:

Bugbear 06-24-2015 02:43 PM

that´s what i call a big gun. :D
you've got the DAK-tiger I'm always looking for. :yell:

Fledermaus 06-25-2015 12:32 AM

Hi Bugbear, yes its a big gun, still deciding where Im going to display it when finished. The tiger I got it on ebay, I was bidding on one and thingking I was not going to win it I bid on a second One, ended wining both for 100 each. I keep both for a couple of moths and finally sold the second one on ebay, and for my surprice it sold for 200 so I can say the one I kept was for free. Now this are hard to find and very expensive :eek:.

Hi to all and thanks for your comments, here with an update on the Dora, work continues on the 8 cars brake system and wheels.

The brake system is very detailed and has many parts making it time consuming
The wheels and axles are cleaned and ready to install
With the brakes finished I installed the sides of the car followed by the wheels, the walls snaps in to place neatly and also have bolts to secure and reinforce it.
All the parts glued in place
Next upper part of the car is detailed and the side ladders are assembled, please note that the parts position are reversed on the instructions, so part 19 goes on the upper side and 20 goes down.
The front of the car is also very detailed and the coupling mechanism is movable.
Side and top details
The other end car
This two were once a long 10 axle car, you can see the differences between each.
Now you have four of each, 4 for the front and four for the back of the main carriage.
Finally I made 8 end plates out of styrene sheet to cover the end of each car were it was cut
After the cars are finished I took a look at the aluminum rails and noticed it look oversize,
so I search on other Dora builds and confirmed the rails are too big. The rails are 8mm tall by 7.1
Wide, compared to a regular trumpeter rail that is 5 mm tall by 3.1 wide. Here you can see the
Difference in size
A trumpeter figure with the aluminum rail

Fledermaus 06-28-2015 04:22 PM
And both rails
The model comes with its own base; it is nicely detailed very strong and heavy but in my opinion
The ballast is way too big
next another problem encountered is that the width between the rails is 45mm on the Dora rails, the standard rail width is 41mm in 1/35 scale. So if I’m going to use the trumpeter rails I need to modify the wheels on all the cars to fit the trumpeter track. I searched again on other old builds and this guy discovered that the inside spacer on the wheel is 2 mm Width, so by removing it the inside width can be adjusted to 41mm, yes! All this means the original base is not going to be used unless I can come with an idea of how to. So by now I will keep working with trumpeters
Now I have to carefully remove all the axles from each car to make the modification, remove 2mm from inside each wheel
So with my dremel I removed the plastic, leaving it level is exactly 2mm
Now it looks like this
All installed in place again, the wheels are dry mounted so if I want to use the original rail with the original base all you have to do is move the wheels to the side and it will be 45mm again
So I tested the car on a trumpeter track and it worked perfectly

With this the cars are finished, now I started to work on the bridges that go between each set of cars.
thanks for watching!

Gopher 06-30-2015 02:57 PM

Good start Abdin!

Fledermaus 06-30-2015 08:42 PM

Thanks Andrew, more soon ;)

Hi, here with another update on the Dora build, started to work on the bridges connecting the cars.
Here one of the bridges, very nice details, even the welding on the sides is all there.
First the PE wire mesh is installed
Next the small 2 steps ladders are constructed, they made the ladders with only double tubes
As steps, in my opinion and after looking all over the book I don’t think it is right. So with balsa wood I constructed the steps for each ladder.
In this photo you can see what I mean by double tubes steps, and the new wood step
The finished ladder looks way better with the wood steps
Now the storage boxes on front of the cars are modified, the hinge details are too big, so with a
Small file I sanded it down to a more to scale size.
Now that the hinges are resized I added details and latches to the small access door on top of the box
Also handles made with copper wire
The other box is detailed also
The strange looking locking system is my interpretation of it after melting my eyes looking at the photos on the Taube book
Some rivet details were added with archers resin rivet detail decals
Here the ladders and boxes in place
Now I moved to the installation of the hand rails, as you can see this are way too tall, to the trumpeter figure body it is up to his chest.

I’m thinking between cutting it down to the correct high or replacing it with brass rod.
Thanks for watching

mike walsh 07-25-2015 07:14 PM

Wow , this is impressive , it is huuuge .

You may need a proper industrial spray gun to paint this devil .
Nice work , look forward to seeing more.



Fledermaus 08-20-2015 07:39 PM

Hi guys!
Update on the Dora continues, the brass arrived and started to make the needed hand rails.
I used K&S brass rod 1.5mm
Using the original handrails as a guide, the different pieces are held together with tape to be soldered
The finished parts for one of the cars ready to install
Now it looks like this with the new handrails, these are now 27mm tall from the floor to the top of the rail tube. After observing the original photos and comparing it to the rails on the trumpeters Leopold it now looks right.
Now with the rails height corrected, the large storage box of on one of the front cars needs to be corrected to match the new height.
I Used 2.5 x 3mm square styrene rod to make the box match the new height of the handrail.

Fledermaus 08-20-2015 07:40 PM

The new parts glued in place
Small styrene triangles are cut to make the reinforcements on the box sides
The finished box
Now the box and the handrails are the same height
Now I moved to the trunnions, this are the parts that hold the complete gun assembly on both sides of the main carriage. The trunnions where finished before I decided to redo all the handrails so I had to remove all the handrails and supports from each side
The platform or bridge of the trunnion is also assembled and the new handrail constructed and installed

Now working on the side handrails of the trunnions, almost done. More coming.

Gopher 08-21-2015 03:15 PM

Great work so far, Abdin!

brokeneagle 08-22-2015 06:22 AM

That's fanatastic work your doing on this kit - what are u using for reference?


Fledermaus 08-22-2015 03:55 PM

Thanks Andrey ;)

Hi Ian, Im using the book "Deutsche Eisenbahn Geschütze" by Gerhard Taube
Its the best reference on Dora, it also has some info on the Leopold but mostly is
All Dora. The only drawback is its in german, but loaded with photos of dora being
Assembled, very good book. Also it shows the giant gantry cranes used to assemble
The gun on site. I ordered it from Gemany through book looker.its hard to find in the
States. :)

schlichtr 08-23-2015 10:40 AM

Man that is going to be big. Have you cleaned out the garage yet? Great job.


Fledermaus 08-24-2015 12:07 PM

Hi Roy, I already sold the car, maybe the next is the jetboat, will see how much more space is needed...:D:p

Pvt Mutt 08-24-2015 01:00 PM

My brother built one of these and it's a monster.:eek:

excellent work so far.

Tony and Michael thanks :)

So here is a update on the Dora work, sorry it takes so long between updates but the amount of work is immense, lots of hours making parts and soldering brass. I started working on the trunnions, this are the parts that holds the gun to the main carriage. I already glued in place the catwalks and original handrails some time ago before I went for the brass handrails, so I removed it and started to construct and add more details to the trunnions.
Here the original handrails
The upper and lower handrails come as a one part assembly
And the upper handrails
All removed and ready for the replacements
The upper handrail is made, please note the different pattern on the supporting rods, the original had a simplified pattern, after looking at the book photos and other builds I was able to figure the new pattern
Here the original rails are missing a couple of the support rods ends. Note the difference.
The upper handrails are assembled and the pattern is also changed as per the original photos. The small squares at the bottom of the support rods are 2mm by 2mm styrene square rod. The top of the original anchoring piece was cut as it was exactly the same diameter as the brass rods 1.5mm, so in order for the brass to fit I had to use the 2mm squares, this where drilled to size before gluing in place
Next using 1.5 styrene rod I constructed the lower catwalk supports, the lower catwalk hangs from the upper one by this tubes and also is attached to the side of the main carriage by steel beams. Again the pattern is different from the original.
The upper catwalk also received the supporting arms as seen on Herr Taube book, this where constructed with styrene T rod and squares of 2x4mm styrene
This area on the front of the trunnions is an access to the interior, it is a bolted hatch, after sanding smooth a styrene disk is cut, I detailed it with Verlinden bolts and glued it in place.
The trunnions storage boxes are replaced also, this are too thick and also the wrong shape, again thanks to the book photos I made the new parts from styrene card.
The original box
Replacement styrene parts ready to assemble
The new boxes
Next I removed the reinforcement triangles from the original boxes and glued to the new ones
Here the completed new boxes
Now the trunnions look like this with all the changes

Fledermaus 09-24-2015 01:45 PM
That’s all the work for now on the trunnios, still some bolt details to add. I have started to work on the main body halves adding details and correcting some parts, so will post as soon as finished.
Thanks for watching

Pvt Mutt 09-24-2015 01:56 PM

Abdin my brother was so involved with his he would sleep two or three hours
every eight to ten hours get up and get right back to building.
He followed this routine until it was finished.:eek:

Only a plastic addict would abuse himself like that.

Keep your progress coming but get some sleep as well buddy:D

Gopher 09-24-2015 02:13 PM

Ones again - great work!

Fledermaus 09-24-2015 08:03 PM

Andrey thanks my friend

Tony Im working on this thing every day, no matter if it is a little or a lot, its becoming an obsession. Just dont want to take long as I did with the schnellboot. ;) :eek:

Pvt Mutt 09-24-2015 10:41 PM

Oh I didn't mind the wait because that boat was K I L L E R:thumb:

Thanks greybeard :)

Thanks Tony, I did enjoyed every step of that build, I love to do missing details to make the model look more close to the original, the same here. :rolleyes:


canjuaan 09-29-2015 08:19 AM

Just yesterday I had a conversation with a friend who is interested in buying the Dora kit. I told him I knew of one build, but wouldn't remember where I'd seen it. Today I visit PA and ta-da, here it is :)
I think he'll enjoy your build as much as I did, and it will help him decide whether to really buy it. Great additional work. I wonder how many bottles of paint this monster will eat up. :p


Fledermaus 10-06-2015 10:32 PM

Hi Johannes, tell your friend to go for it, its a nice model as it comes, Im just correcting and
Adding details to make it even more interesting than what it already is. It is very nicely detailed, a really fun model to build.


Fledermaus 10-06-2015 10:40 PM

Not sure about that but I have about 10 bottles of modelmasters panzer grey to start painting
Will see how much more is needed. It already has taken 3 1/2 bottles of plastic weld glue and still a lot to do. :eek::eek::D

Its a big monster


canjuaan 10-10-2015 05:08 AM

Wow, that beast is really hungry! :eek::)


Fledermaus 12-07-2015 12:22 PM

The work continues on Dora, it’s time to do the main body halves. The first issue is an error on the instructions. It tells you to assemble parts L4 with L2 (and L3 with L1) but if you do so the assemblies holding the two halves together will be on the wrong position. Parts O12, O3 and O11 (assembly step # 18) goes on the front of the main body and L7 (assembly step #20) goes to the rear of the body. So to correct this problem all you have to do is invert parts L2 and L1 as this parts are symmetrical, so now you will glue L4 with L1 and L2 with L3 and the problem is solved.
Here are the main body parts
And the inner parts
The inside of the body is very well reinforced to hold the weight of the gun Trunnions and main loading platform
Front area has the four holes
Rear area has two rectangular openings
This is how is done
With all in the right position it looks like this
The parts that hold the two halves together are assembled and rectangular pieces of styrene 3mm x 6mm are glued to act as the bases for the lifting cable
Eyelets, this are made using soldering wire
Then small pieces of styrene rod are used to make the bolts for the plates
Finally using 3 strands of gauge 34 brass wire twisted together I made the lifting cable for
the front and rear parts
Now the real work started, what are supposed to be the hydraulic bottles are
Terrible, so new ones are constructed using styrene tube

Fledermaus 12-07-2015 12:23 PM

So to rectify it you need to remove all the original bottles on the outside and inside of the main bodies
This are the new bottles parts
Here the replacements are glued in place
For the top of the bottles I made a master using the same styrene tube and with a rounded top using green putty finished with a smaller tube on top as the connection for the hydraulic pipe
Using card board I made the box for the rtv rubber
All the needed tops are made with one to one resin
It now looks like this
Next all the vertical steel ribs received a strip of 4mm wide styrene to make the flange as seen in the photos of Dora
the pipes for the hydraulic bottles are made with tube from the original handrails
And installed
Now the stabilizer platform must be divided in 3 separate parts, a 3mm wide channel is cut in these areas in the photo
Inside view
This areas are open on the original vehicle, so after making several holes the
Plastic was cut and sanded to shape
This is how it looks now, all this changes are to be done to both side inside and outside
I’m working on the catwalks, handrails and ladders for the main bodies so the work continues.

Thanks for watching


Gopher 12-07-2015 03:46 PM

You're crazy! =)

Fledermaus 12-07-2015 06:19 PM

:D hahaha Andrey you know me, I like to always complicate my builds :D:yell:

Fledermaus 02-17-2016 06:56 AM

Hi my friends, its time for another update on Dora, the work on the main bodies continues with more modifications and adding some missing details.
On top of both sides are hatches missing, so using styrene and some left over photo eched
Pieces the hatches are constructed
This is the area for the hatches to be added
First I removed some bolt detail and filled the area with styrene to make it a flat surface
Again using styrene sheet I made the doors and glued PE hinges And a brass wire handle to each door
The finished hatch
Now the poles that goes on top of this area are drilled on the sides as seen in the pictures of the real Dora
And in place
Now the holes under the body must be copied to the other side of the carriage, this hold with screws the parts that join the two main bodies together.
After measuring the new location I started to drill the new holes
Here the holes are done and a dry fit of the part.
With this done I moved to the inside halves, replaced the hydraulic bottles and made the cut on the platforms, then started with the vertical flange detail, like in the outside I used .40x4mm wide strips.
After all the vertical flanges are glued I started with the horizontal ones
Each section is made with a piece of .40 styrene 8mm wide, then I made a 2mm line across and to the sides, finally a diagonal cut on the two corners and a cut across gets it done

Fledermaus 02-17-2016 06:57 AM
With all the flange work done, I started to make the missing ribs and pipes at both ends of the inside halves. With the measurements done its starts
This are the parts for the front area
This are already drilled for the pipes to fit thought
The hole where the pipes connects to the body is marked and with a drill it is started, then sanded to shape, finally a piece of styrene is glued to the inside with the 4 holes for the
Pipes to connect.
Here the parts are in place ready for the pipes to be added
The back area is marked and the parts glued like in the front
The back and front received the brass pipes
That’s all for the moment, currently working on the extra valve bodies and hand wheels needed
For this areas, thanks for watching.
