Thanks to everyone for your interest and comments.

Bill and Russ:
Actually, all the necessary signs fit on a postcard. But you can only buy whole boxes of photo paper from us, at an outrageous price. I have therefore printed the signs on relatively thick and smooth paper, which you can get as individual sheets, on a trial basis. I'll see if anyone of my friends can help me out with a single sheet of photo paper.
This sealing of photos: could it be that they have been laminated? I do have a laminator.
You're really right about the Danger sign. I'll have to redraw that. Incidentally, of course, I don't know when these signs were attached to the machines.

I use (custom) waterslide decals for things like signs.

Not easy for one or two in a hurry, but fine if you can plan ahead.

pdc.ca use a high resolution laser for full colour (+white).  Highly recommended.

I don't have a handy pic of any signs (and I've misplaced my unused stock), but attached wagon lettering uses the decals (9mm/ft scale).  An added benefit is that the decals can be distressed to fade the lettering.  I used a fibreglass brush to scuff up the wagon numbers here.

Generally vector graphics will give a better result than raster, so ideally draw signs rather than using images.  Nevertheless images can still work very well.
Cheers,

Lawrence, that was actually my first thought too, to stick a decal on a thin sheet of metal. But I've already had bad experiences with this. Although I sealed the decal well with clear varnish, wash crept between the decal and the sheet metal due to capillary action during the subsequent ageing process.
That's why I first tried Volker's method. With Volker's help, I'm sure I'll get somewhere.

Do you have any plans to showcase this incredible project to the public? I am very eager to see it in person and literally willing to go to great lengths to do so!

Hauk, I don't have any such events planned at the moment. But if you're ever in my area, my door is always open. I would be very happy about a visit, also from any other forum member. There is also always enough cold beer in the cellar for a cozy evening.

Hope to take you up on your kind offer one day!

Hello Bernhard,

it's impressive how you arrange the amount of parts!
Even if it is "only" 1:32, the dimensions of your prototype are simply enormous!

I have one question about your numbering on the line drawings. Do you name the individual parts by name or just number them consecutively?
I am still pleased that you are reproducing the rivets. :)

     Your question from 17 July about how the signs are attached to the crane, I might have an answer.  In the early 1970's I worked for the shipyard in Newport News, Va and there were small and medium signs located all over the ships under construction.  Those on hatches (doors to you) which indicated whether or not they were normally open or sealed were marked with a sign glued to the hatch.  Others if not applied to a water tight bulkhead were simply screwed in place.  If you have a high resolution image blow it up and look at the corners of the sign, I feel you will find shadows of the screw or bolt heads in each corner.

I was in Switzerland in May...I had this idea I should look you up. But I was there with a new lady friend and we had a jamb packed schedule. She is half Swiss and there were relatives to see ...and those mountains! Maybe next time, she would like to see your work too.

Speaking of visits, Stuart and his wife visited my wife and me a couple of weeks ago. I only knew Stuart from the forum and a couple of e-mails. We spent an entire afternoon together and had a great time. I encourage any of us on the forum to visit each other when an opportunity presents itself. -- Russ

Thank you Frithjof. Each individual part and sub-assembly have its own number. The individual parts of the sub-assemblies have sub-numbers, e.g. 1534.01, 1534.02 ... So, I can clearly identify all parts in the parts list.

Thanks for your tip, Lawton. Such information from contemporary witnesses is always welcome. I will recreate the mounting accordingly.

Paul, you are of course always welcome to an interesting exchange between modellers!

I can only agree with that!

Before I really start working on the main girders, I have to take care of one special detail. One design detail can often be seen on the main girders, but also on other assemblies such as the trolley or the walking beam: vertical reinforcing angles that are squeezed on one or both sides so that they overlap a horizontal angle underneath.
Shown here on a drawing of the main girders, ...

... or in the original, e.g. on the walking beam.

I want to reproduce this exactly in the model. On a 3 x 3 mm angle it will look something like this:

I have to build a pressing tool for the production. I bought a suitable toggle press from a classified ad.

The necessary pressing tool consists of just a few parts.

Two angle profiles are inserted into the tool from behind and clamped.

The angles are guided in the punch in such a way that they cannot move sideways during the forming process.
