The axles and the drive mechanism are very well made and look good too.

I am still reeling in stunned disbelief at the perfection of the fabrication and assembly just as I have been after reading all previous posts. Most satisfactory. -- Russ

From the clutch for switching between forward and reverse driving I have no pictures of the prototype. So I improvised a little bit at this point.

The clutch is turned, drilled and two pins are inserted.

The lever for operating the clutch is soldered together from a few parts.

I wanted to etch the shifting gate for the clutch lever as well. But somehow the part disappeared from the etching template. In my material box I found a blank for a clock board, from which I can mill the part.

On the rotary table, the part is first milled to thickness, drilled, and finally separated from the blank.

Now only the mount has to be soldered to the shifting gate.

The next sub-assembly is the brake. Since it is relatively simple, it is designed to be functional.

First, the pressure levers that press the brake pads onto the wheels are soldered together.
