Awesome!

Gentlemen - thank you very much for your words of praise

Now it's time for a bit of hard work again.

The western and eastern side bridges are mounted on support beams, each consisting of 137 individual parts.

The two sets of four inner cross members are mounted and soldered using a small Pertinax jig.

The six 1.0 mm rivets on the sides fit into the corresponding holes from the long beams.

As a test, the first loosely assembled support beam was inserted into the left portal beam - everything fits so far

A number of wire pins in the upper area of the gantry beam still need to be wound into rivet heads.

Wow. -- Russ

Step by step, the project is becoming more and more impressive.

The next steps will follow, so there are a few small parts again today.

In some places, I won't be able to use the finishing cutter to round off the second side of the rivet head when it is installed.
In contrast to the wire pins normally used as rivet replacements, I have fitted some angles and U-profiles with 1.0mm rivets (head diameter 1.3mm - shank 1.0mm). I accepted the different diameters of the head and the opposite side. On the one hand, the corners are hardly visible later and on the other hand, the slightly larger head diameter provides a little more security against falling out when soldering the neighboring parts when assembling the many individual pieces.

Small Pertinax gauges were again used for the vertical and parallel alignment.

Four of these rivets were soldered into the 6.5mm x 6.5mm nickel silver sheet. My existing rivets were a little too long at 6.0mm, so I had to shorten them first.

I used a 2.0mm thick aluminum angle from the leftover box. The excessively long rivets were inserted into eight 1.0mm holes drilled and shortened on the underside with a side cutter. I then sanded the whole unit smooth on a 400 grit sandpaper, holding the small rivet heads in place with a piece of wood (in the following picture, the piece of wood is pushed to one side to show the rivet heads).

I then wound the small nickel silver plate with the four shortened rivets...

...a 0.5mm brass sheet with corresponding holes served as a spacer when working with the finishing burr.

The first of two parts is ready to fit.

The two support beams are connected to the two lateral portal beam tower sides with the aid of eight straight and eight beveled small L-profiles.

Träger-Montage 118 (fspg2)



These were also fitted with the 1.0 mm rivets and soldered in two corresponding Pertinax gauges.

Träger-Montage 115 (fspg2)



The rivets of the L-profile still need to be shortened and rounded off.

Compared to this, my models are crude toys. -- Russ

[Lawrence@NZFinescale]

We should form a support group...

[Bernhard]

Perfect details. Are the long parts also sandblasted? If so, how do you do that?

Bernhard

I think you could probably teach the builders of the real bridge a thing or two!
