Title: Dürkopp 80hp tractor
Post by: Peter_T1958 on August 21, 2024, 02:17:50 AM
At the very beginning of my ,,Büssing" thread (https://www.finescalerr.com/smf/index.php?msg=71306) I posted some test photos of the ,,Dürkopp 80hp" tractor. Meanwhile the first run (twenty vehicles) had been produced and was immediately sold out. For me, that's astonishing since this is more then a very exotic subject.

The following pictures from the building stage are done by master modeler Vinzenco Lanna and not by myself. You may have noticed that I am terrible slow in modelling...

Extremly crisp and finely detailed parts!
I presume they are all 3D-printed? Do you mind telling us a little more about the printer and resin used?

A small batch is produced by a French company (as already my Büssing tractor). So I have absolute no information about the resin or the printer he uses. I personally do not own a 3D printer ![/b]
Another issue is the sales price. On one occasion the high price of this kit (152€) has been criticised on facebook. Yes, it's a lot of money, but when to take into account all my research over the last thirty years and costs to take this into production, it is surprisingly cheap (from the point of view of the designer  ::) ).
To take just one small example: the manual with the technical drawings was sold once on Ebay for more then 600 €. Jochen Vollert from «Tankograd publishing» kindly gave me copies of that manual for free! One can imagine that no one in this business makes a lot of money. Our goal is to pass historical knowledge that is almost gone to an interested public.

It's a shame, but welcome to the real world. You're in good company.

How did you form the tarpaulin? (That's my way to say that this is an absolutely outstanding model, starting from research over construction to even providing a kit.).

Cheers,
Volker

First, the basic shape was drawn as cross sections which were connected/shaped to a solid body. Afterwards folding and bulges were done in « Blender ». If you are interested, here a short video to illustrate how I did the workable chains:

An absolutely superb model. Ignore the idiots who complain about its price; they have no concept of what goes into research, design, and production. -- Russ

Have you seen what the Wingnut Wings kits go for these days ? They make this limited edition model look like a bargain . Any way , there are obviously modellers out there who are prepared to spend 152Euros on such an unusual subject if it sold out so quickly. The people who complain about the price can always buy the latest model by Tamiya for much less .

    You will always find cheapskates in this hobby , just take Russ for example, he builds his models out of old bits of cardboard, but there are plenty who appreciate quality when they see it . If this model was of a subject that I was interested in  I would quite happily pay that sort of money .

Thank you all for your kind words! After having finished my Büssing my motivation is/was within limits to do another model of similar character, so the Dürkopp lies still unpacked in my stash! BUT...
... a recent discovery after thorough analysis of existing pictures led to completely new insights concerning the 100hp version of that Dürkopp tractor. As far as I can make out, it could be possible to design this huge vehicle without countless modifications (Observant readers may have noticed that the my interest in a new project is sparked ... ::) ).

Your model is superb! So much great detail, and the parts are very cleanly printed.

That 100hp tractor is a beast!

Thanks! And yes, the enormous 100hp Dürkopp tractor would have surpassed all! It was a truly amazing sight and my alltime favorite. Once I wrote about that in the «Büssing» thread. At that time I still had no idea, how the monstrous rear wheel was positioned within the frame. There were some modifications not only in relation to the frame (due to the wheel's bigger diameter) but also in relation to the transmission, as the chain sprocket has moved above the frame, and much more!
Alas, according to the producer's philosophy to bring out the most reliable prototypes, the big Dürkopp was not an option – up to now!

In the meantime I discovered by sheer coincidence some cruical documents, that show the frame modifications and also a photo of the gearbox too! But I don't want to inform my producer yet, as I don't want to suffer stress at work... ;D

May be I should rename this thread in "Dürkopp 100hp"  ???

I am getting along better and better with the «Grosser Dürkopp». Indeed, it's the small things which can cause most efforts. During the past week I was working on the attachment equipment - hundreds of work stages. Here a comparison to the picture in the vehicles manual :

And here a front view of that strange vehicle:

Seen from the outside you may have the impression that « Scratch-CADing » is less  time-consuming than real scratch building. It is not! Though the mayor advantage is that it offers the possibility to adjust and redo each parts again and again. :-\
So, I needed two weeks to finish the «right» attachement equippment.
But I am quite pleased as it turned out!

This is the great advantage of 3D CAD. You can modify the models with relatively little effort. When I think back to how laborious it was on the drawing board ...

There were quite some changes. Here the files of the frame construction. I usually save mayor changes by consecutive numbers. If I have to start again from the beginning, I save it under the next number of tens, and so on...

On the finishing straight, finally! Here the box art of the 100 hp Dürkopp.
If the truth be told, I was getting a little bit tired of the project now  :-\
And the stash of unmade models is growing steadily...

Yes, I am also proud of it. But the main impetus to do these vehicles is to share informations about a rather specific topic that I collected over more than thirty years before it will disappear one day. I also shared photos and plans with other producers as I can't make everything by myself.

Here the collection of german artillery tractors we did up to now...

It is amazing how quickly a new product finds an imitator, even in this limited field. On the very beginning of my thead I posted photos of «my» Dürkopp tractor.

That's a fantastic diorama—so much life packed into such a small space. The lighting and layering really sell the depth. Is the backdrop hand-painted or a photo?
