Now there has been further progress.
First, a few track boards were milled from 3.0 mm HDF. They were milled with 1.5 mm deep grooves for the rail profiles. (Here again, please note that the light railway did not run over the weir in the prototype!)
In addition, there were 3.5 mm x 2.0 mm milled recesses for the railing profiles.

Delvenau-Geländerstützen_02 (fspg2)



The 5.0 mm high HDF wall stones are located on the sides. Both the rail profiles and the side blocks protrude 2.0 mm above the (yellow-marked track board) – enough space to fill the floor with sand and boards.

In the following three color images, the milled wall sections have already been colored, but only loosely assembled!

Similar to how my father was photographed on the Wehr in 1962, ...

...I wanted to stand there myself once—even if only as a 3D-printed figure.

Here you can see how the 3.0 mm track board serves as a stop for the outer brick edges.

Initially, I wanted to have the 40 railing supports I needed cast in 3D from brass using the lost wax casting process... but the price of over €300.00 for 40 railing supports from a well-known supplier was not worth it to me. Even though I would like to use metal where it was also used in the prototype, I decided to look for a sturdy alternative.
I remembered that Kalle had shown a railing for 0 gauge at an exhibition a few years ago that was relatively sturdy yet slightly flexible. It could be bent easily and then returned to its original shape without breaking.

Delvenau-Geländerstützen_04 (fspg2)



Within just four days, the parts were in front of me... now I have to sand down the tiny remnants of the support structures on one side of the leg using 600-grit sandpaper before I can install the other brass tubes.

The bridge is progressing beautifully. I like the little loco, too. -- Russ

@Russ

I reported on the small light railway locomotive here quite some time ago...  Click: here

I guess I'll have to do something more about that soon ;-)


Today, there is a little more to see from the Delvenau segment.

This is how it was planned:

Delvenau_Unterbau_03 (fspg2)


Delvenau_Unterbau_04 (fspg2)



Screenshots of the two outer sides, each 10,000 pixels wide, were printed on several A4 sheets of paper and glued together so that I obtained the respective outer lengths of the side walls.
These paper templates then served as a guide for the jigsaw.

Delvenau_Unterbau_05 (fspg2)



An attempt with a jigsaw blade, which caused the edges on the underside to tear, was not very convincing.

Stichsägeblätter_Verzahnung (fspg2)



Instead, I used a fine-toothed saw blade for metal. I had previously applied adhesive tape firmly to both sides of the cut edges, which allowed me to almost completely avoid tearing on the front.


I did the sawing in the workshop area to keep the module area as dust-free as possible.

Delvenau_Unterbau_06 (fspg2)



In the meantime, the segment has been repositioned at its destination:

Delvenau_Unterbau_07 (fspg2)


Delvenau_Unterbau_08 (fspg2)

I remembered the little switcher so I guess you'll have to finish it someday. Meanwhile the Delvenau section is coming along beautifully. -- Russ

Next, the Delvenau segment was coated with colorless hard oil.
Then, 25 mm long 3.0 mm brass round material - inserted into telephone jacks - was mounted as a fitting, as shown here:

Steckverbindung (fspg2)



Here is a view from the bridgehead - the segment is only loosely inserted so far, but shows the planned route.

Before landscaping can really get underway, a few parts still need to be added to the Delvenau weir.

There is an "extension" at the rear with a concrete slab, the function of which I have not yet been able to determine.

As shown here recently:

So, based on these two illustrations, this complex was also drawn.

Delvenau_Wehr_47 (fspg2)



Inside, a 5.0 mm HDF frame will ensure the precise alignment of the individual wall panels.

Delvenau_Wehr_48 (fspg2)


Delvenau_Wehr_49 (fspg2)


As can be seen in the picture above Delvenau_Wehr_20, the vertical corner stones were probably rounded.

In the model, I rounded the corresponding edges using an R=4.0 mm rounding cutter.
To avoid damaging the HDF material, I used several depth settings to achieve the final result.


Delvenau_Wehr_52 (fspg2)




Here, too, I recut the joints with a 0.5 mm saw blade.
Before the part is glued to the weir, the corner stones will be painted.

Delvenau_Wehr_53 (fspg2)



Until now, I had only seen the front of the Delvenau weir in the following two pictures:

Then, on a website documenting the http://www.rondeshagen.com/Schleuse_in_%20Lauenburg.html[/color]]demolition of the old Lauenburg lock, I found a picture that, when enlarged significantly, revealed another detail that was not visible in the pictures I was familiar with:



Delvenau_Wehr_50 (fspg2)



Unfortunately, as I am not familiar with the exact dimensions and type of construction, this culvert was improvised somewhat.

Delvenau_Wehr_55 (fspg2)


Delvenau_Wehr_56 (fspg2)



The front has already been given a few initial signs of aging.

Delvenau_Wehr_54 (fspg2)

Frithjof,
Your work continues to be terrific both in the details and the overall construction.

I hope your heirs find a prestigious museum that, someday, will be home to the layout. The research, design, and construction make it truly remarkable. -- Russ

Just stunning!
It is way beyond my pea brain to begin to comprehend all of this.

Hi everyone,

Volker and Toni visited me last weekend. Unfortunately, we live quite far apart, so it had been three and a half years since we last met.
This meant we had all the more to see and discuss—in far too little time...

Volker and I discussed my interpretation of the round arch in more detail and took another look at the two pictures (Delvenau_Wehr_27 and Delvenau_Wehr_50)...

Delvenau_Wehr_58 (fspg2)


Delvenau_Wehr_59 (fspg2)


Delvenau_Wehr_60 (fspg2)


Delvenau_Wehr_61 (fspg2)


... with the result that I have to agree with Volker: the version I built with a round arch (on the right in the picture) will be replaced by an H-profile support structure with wooden planking—more on that later!


At least the area has now been cleared again with a plunge saw blade:

Delvenau_Wehr_62 (fspg2)



A little milling was done as well...

(photographed through a window by Volker)


Toni had brought along his fantastic homemade Decauville steam locomotive with a few wagons and placed it on the tracks. Since no locomotive had traveled up the incline for around nine years, the tracks first had to be cleaned.

Thank you for all the information. This is fascinating to me (us)
Martin

What a terrific time you must have had. Toni's Decauville and rolling stock are superb. Anything Volker does, including his advice, is worth paying for. Still, it's too bad you had to remove a piece of your bridge. I hope you can use all or part of it as scenery somewhere else. -- Russ

Thank you!

@Russ

It was indeed a great weekend!

Payment is such a strange thing... what is the right payment method?  What seems too much to one person may not be enough for another...

Here's a little story about that:
Many years ago, I had a request from a gauge 0 model railroad enthusiast asking if I could mill the "old storage shed" to a scale of 1:45....

Alter_Lagerschuppen_264 (fspg2)


During our conversation, I mentioned that the milling machine alone would need a good 83 hours to mill all the HDF wall panels for the interior and exterior walls (my scale is 1:22.5).
When I asked him what he thought my work was worth... After some consideration, he said: €20.00...
From his point of view, the milling machine would need significantly less time for a quarter of the respective surfaces, and besides, a milling machine like that runs all by itself...
He had probably overlooked the fact that instead of a 0.5 mm milling cutter for the wall joints, I would now have to set a significantly slower feed rate with a 0.25 mm milling cutter so that such a solid carbide milling cutter would not break off immediately!
Even if I hadn't needed so much HDF material, it would still have taken at least 70 hours, not counting the time spent preparing the milling files!

Conclusion:
I am very happy that I got to know Volker many years ago and that we support each other with advice and assistance! One thing is certain: Volker is priceless... How much would his house Lohmann cost if you counted the countless hours alone, not to mention the many ideas that he implements so ingeniously?


In the meantime, a little progress has been made with the new small bridge.

Delvenau_Wehr_63 (fspg2)


Delvenau_Wehr_64 (fspg2)



The two bridge heads were re-milled and glued together with the help of many small clamps.

Delvenau_Wehr_66 (fspg2)



Wooden planks will be laid to the right and left of the track. To this end, I have milled a few recesses into an old Pertinax board, which will allow me to precisely align both the lower boards running lengthwise and the 8.0 mm x 3.0 mm crosswise planks made of lime wood when gluing them together.

Delvenau_Wehr_67 (fspg2)



To prevent the glue from bonding with the Pertinax template, a thin layer of cling film was used as a separator.

Delvenau_Wehr_68 (fspg2)



The Pertinax jig remained on the milling machine during gluing so that the corresponding 3.5 mm x 2.0 mm holes for the railing supports could be milled out after drying.
 
Delvenau_Wehr_69 (fspg2)



Then the the middle section was removed. This will later hold the rails and the parallel lime wood boards.

Delvenau_Wehr_70 (fspg2)


Delvenau_Wehr_71 (fspg2)



The six support beams each had two 1.1 mm holes drilled for the M1.0 hexagon head screws.

B]Delvenau_Wehr_72[/B] (fspg2)



Delvenau_Wehr_78 (fspg2)




The four cross members are connected with small L-profiles.

Delvenau_Wehr_73 (fspg2)



A few more pieces were milled from 3.0 mm x 3.0 mm L-profiles, as I had not yet manufactured enough parts for the four secondary bridges on the lifting bridge.
Two of these profiles were inserted back-to-back into a 1.0 mm wide and 3.0 mm deep milled groove. One leg was marked with three dots for the rivet heads to be pressed in later, and the opposite leg was marked with two dots.
The same process was repeated after I had swapped the two profiles.
I achieved the exact positioning using a small stop, on the left in the picture.
Yellow adhesive tape secured the parts during the individual processing steps.
A 1.0 mm milling cutter then cut 0.5 mm deep into the upper legs – after which the profiles were swapped again so that the second leg side also had the correct shape.


Delvenau_Wehr_74 (fspg2)



In the end, I ended up with 24 individual angle profiles, which only needed to have their rivet heads added on the embossing machine.

Delvenau_Wehr_75 (fspg2)


The small parts were held in position in the slotted punch using pointed tweezers when pressing.





The following picture was taken in an improvised photo studio on a windowsill with snow on the window pane.

Delvenau_Wehr_77 (fspg2)


Next, the individual parts are placed in the correct position using a few milled Pertinax gauges and soldered together.

Beautiful!

I hope you don't think I was suggesting you should pay Volker! I was just trying to express the value of his advice. I could say the same thing about your exquisite modeling and the talent and expertise evident in your work. Your perfect bridge is just one example. -- Russ

Extra - exhilarating stuff this and I just love the little steam loco.
