The two rails can then be fitted.

Now the individual parts required for the supports for the side walkway are cut to length and fitted with rivets.



For soldering the individual parts, I mill two jigs into a Resopal panel.



The supports can then be soldered together to fit precisely.

The finished parts are ready to be attached to the main girder.



They are soldered to the main girder using an improvised soldering aid.







As a next step, I have decided to tackle the second carrier. As long as I still have some idea of how I built the first one. Because I have already made many parts with the first carrier, this is also pleasingly quick and uncomplicated. At the moment it's practically finished and is waiting for the rails and supports to be fitted.

I can't get over how massive this thing is going to be!

I am simply overwhelmed. Such a professional approach - and furthermore very forward planning! It's actually a fact, that modelling skill or the knowledge about how something was made fade away. To my experience that knowledge is stored not only in our memory but also in our hands etc. (comparable with the skill to jump from a springboard). So you should do well tackle down the second carrier now !

Bernhard,

this is so well executed - I'm overwhelmed!

Bernhard,

even if I have already told you once, I am totally thrilled!!!

Bernhard,

Between you and Frithjof's project, my head is swimming!

Thank you for your interest in the project.

Here are two pictures of the assembly of the right girder.





For the truss, I had four sheets etched too few. The missing parts, including the bending grooves, are milled from 0.3 mm sheet brass.



The two girders can then be placed next to each other on the towers for the first time.

Now a few supports for the guide rail need to be soldered and fitted.

The parts for the catwalk supports are prepared ...





... and soldered together in a milled soldering jig.

They are then fitted to the girder.

Busbars for the trolley's power supply are mounted on the catwalk supports. These are protected with a curved cover plate.



I built a bending device to produce the 0.2 mm thick brass sheets.



The finished sheet metal should have a bending radius of 4.5 mm. As the sheet springs back slightly after bending, the template has a radius of 4.0 mm.
The sheet metal strip can be pushed into the device up to a stop and then clamped.



The bending shaft and the two levers are then attached.
