Really a lot of work for these small parts. But perfect, as always.

Here I milled something for the Demag ML15.

A 4.5mm brass rod was placed in a 4.5mm deep and 4.5mm wide milled groove and fixed with Tesa tape.
A 1.5mm hole 8.0mm deep was drilled at both ends of the rod. So I was able to secure the rod with two brass pins in the groove against twisting.
Then 2.5mm deep holes were drilled with an 1.4mm cutter (!).
That is, the holes only go to the middle of the bar.
Finally, 2.0mm deep notches were milled close to the milled holes with an 1.0mm cutter.

Because it may be difficult to establish a connection to the small locomotive from the last three pictures, another photo will appear now.
I made the brass rod twice.
In addition, the two 1.5mm holes drilled at the respective ends were used to align the two opposite profiles. 1.5mm brass wires were inserted.
Now the 13 wires (1.4mm in diameter) could be introduced into the opposite blind holes.

No, even if it looks like it will not be a ladder - at the end, only 12 identical parts are required! One part is for exercise ;-)

Originally I wanted to braze the parts.
After two colleagues convinced me to solder the parts softly, I didn't have to "soften" the thin coupling rods.
The stability should also be sufficient, especially since the coupling rods do not transfer any function to the second axis.

The Pertinax gauges kept the two spars at the exact distance when soldering.

Then the little "ladder" was further processed in a new gauge.

Before I drilled the 2.2mm holes into the two end plates, all parts were milled to a height of 1.8mm.

Demag_ML15_Montage_130 (fspg2)

Now the two holes were drilled into the coupling rods.

Demag_ML15_Montage_131 (fspg2)

The upper milled recess had the exact dimensions - it turned out to be too tight when removing the coupling rod.
