And with that this subassembly is also finished. The cover is only loosely attached and does not fit exactly yet.

As can be seen on the prototype photo, the casing has no door. To hide the unsightly parts of the drives, I decided to give the model one.
The hinges consist of tubes with a diameter of 1/0.6 mm and strips 1.5 x 0.3 mm.

Of course, the door also needs a latch.

If I had known it was that easy to build an excavator, I'd have built a couple last week! -- ssuR

The next subassembly is somewhat simpler: the bucket ladder support.
