A few small parts, among others the builders plate

Bernhard

In the first step all loose small parts are chemically blackened.
The remaining parts are prepared for priming.

Bernhard

For primer I have chosen this time a solvent-based paint for industrial application, but it can be applied with the airbrush gun if diluted appropriately.

Bernhard

But this happens if you spray this paint too dry (with too much air, too little paint): it solidifies in the air to a candyfloss like web. This must be carefully removed before further painting.
After drying, the primer appears in a light rust red. This corresponds almost exactly to the color tone, which, weathered and faded, is still partially visible on the prototype.

Bernhard

Now follows the "rusting" of the surfaces. This is quite time-consuming. The paint is not sprayed, but different brown and rust tones are dabbed on with a small sponge. Finally a brown/grey wash is applied.
The surface with the rust and the partly underneath still visible primer does not correspond badly to the prototype.

Now the bucket chain excavator can be reassembled step by step.

The painting and assembling are looking very good.
The "candy floss" from spraying the paint looks like cobwebs coated with flakes of rust.

Hello Bernhard

Great work! The rusty surface ist very well reproduced.

Satisfactory.

At this point I shall disclose that, in contrast to Bernhard's clean, neat organization, during construction my workbench and sub-assemblies generally resemble the devastation from a large bomb explosion. Some have suggested I look like that, too.

Fantastic! The rusty/faded/worn paint looks very authentic.

That candy floss is interesting, I've never seen that happen before.

Simply successful Swiss precision work.

Thanks guys for still following this thread.

There are successes to report. The bucket chain excavator can finally be assembled definitely!
First the closing flap is attached to the discharge hopper.

Bernhard

Next, traction drive and chain drive are installed again.

Bernhard

The bucket ladder support follows. The guy ropes are made of stainless steel with a diameter of 0.27 mm and 49 (!) strands.
