The real side wall, here in1/50 scale in the background, was built up from limestone. This sort of wall you can find in my hometown at almost every corner. The major challenge was to imitate the roughly applyed plaster in the gaps. 

 

 

I have almost finished the scaffold construction on the front and the back side. The ladder in the foreground will be supportet by a gangway that leads from the stone pillar to the riverbank.

Towards the end of my projects imperfections catch one's attention more and more. In the current project, it's the water. It's too clear, a slight opacity would be more realistic. Furthermore, the ripples, caused by currents are only visible from a certain angle. Here is an additional need to improve something.

 

I got a little time in and worked on the brass ladders. In absence of an alternative, I soldered it piece by piece. Countless attempts failed and there are more then one burn marks on my desk! To hold the tiny parts, I had to create or modify some appropriate clothespinds. As you might expected, there are still a lot of ladders to do!

 

Here another detail shot of the mechanism and the stonework. 

A prominent detail of the construction: The lower most gearwheels were protected (from flooding?) by some sort of fenders. They seem to be of zinc coated sheet metal (may be it's more artistic license then reality), so I tried to represent that kind of surface by using a new technique copied from figure modelers: the wet-in-wet acrylic method. As basecolor I used Citadel game Color, Boltgun Metal. Then I applied very thin cloudy coats of creamy white and traces of dark and light rust. This technique allowes you to control the colors carefully.
