Your work is very impressive. (I don't know enough to comment beyond that, but I recognize excellence when I see it).

Holy cow, that is some impressive work! Those tiny pillow blocks look like they're not much bigger than the eye of a needle.

Since it is actually all very small, it is a gigantic work.

Hi Bernhard.
Happy New Year.
this is a very nice piece of model engineering you are a very good machinist. Was this your profession?
cheers

Bernhard

Thank you for your interest, and to all a happy new year.

Kim, I'm an engineer, not a mechanic. But I worked for many years in technical sales for a company that builds special machines for the watch industry, among other things. I learned a lot from them!

Bernhard

Let's start the new year with the production of the casing for the drives. Here the situation on the prototype and the model.

Bernhard

First of all I milled again a gauge for soldering the two inner frames.

Bernhard

In this one the two mirrored frames are soldered.

Bernhard

The two finished frames.

Bernhard

Over the frames come the sheet metal parts, which are etched.

Bernhard

That's pretty good so far.

Bernhard

This is followed by the more complicated casing of the chain drive. The parts are also etched, and must now be assembled into a box.
Since I had little experience with etching at that time, I disassembled the casing into individual parts. It would have been simpler to draw a flat projection with bending edges.

Bernhard

The lower part is already finished.

Bernhard

The upper inner side part must be halved so that the cover can be put on later, after the chain drive wheels have been mounted.
