Your work is very well done for a neat result.

An excellent start. Like Frithjof, I also wondered why you used Loctite. (It seems like a good idea.) -- Russ

Good morning Bernard.
Happy New Year to you and your family.
Yes just echoing the rest of the comments. a very complex project a  very well done miniture.I particularly like the rivets a small item that is often not done well.
All the best Kim

You are building another interesting, complicated machine.

[Bernhard]

Thanks guys for your appreciation and for your interest.
There are several ways to assemble structures with many parts. One is brazing and soldering. But I have not yet dared to braze, because I fear that the small parts warp or even burn. I therefore always solder the basic structure, so that it has enough stability. The remaining small parts are then glued with 2-component glue (or Loctite).

Hallo Bernhard,

For such cases, a resistance solder is very helpful.
Otherwise, I secure neighboring places with toothpaste. After soldering, everything is rinsed with water and soap.

[Bernhard]

Fortunately, I also have the holy grail of soldering technology, a resistor soldering unit. But the toothpaste is a good hint, I have never tried that. Thank you.

As always, I am in awe of this stunning level of precision work!

[Barney]

Just amazing - so fine and precise - and a nice unusual model to build

Bernhard,
I'm pretty speechless. What kind of glue do you use to fix the 3D prints to the brass frame?

Cheers,
Volker

[Bernhard]

Volker, I normally use Araldite Rapid. It sticks very well, but in an emergency the parts can be removed without damage with a little care.
For very small parts, such as fake screw heads, I use CA instant glue.

Thank you for your interest.

The next subassembly are the track units.
This is what the original looks like, ...

[Bernhard]

... and this is the design for the model.

[Bernhard]

The basic bodies of the two crawler tracks are made of solid material.

The bearings for the idlers are soldered together in a simple jig, then cut to the correct length.
