The brake pads are made of plastic so that no short circuit occurs when the wheels come into contact.

The guide plate for the brake lever consists of two etched parts. At the top of the parts there is a toothing in which the pawl of the brake lever engages.

The outer plate gets two feet and one "eye".

The pawl of the brake lever is again a good example for the soldering of small parts.
First a bracket is bent, drilled and then soldered to the handle.

... and finally screwed to the brake lever with a M0.6 screw.

The finished brake lever. The pawl really engages the teeth on the guide plates and locks the brake lever.

Now I have to make the traverse on which the two brake pads are mounted.
Now all parts of this sub-assembly are ready for assembly.

Yes indeed! It's like seeing a Swiss watch being made.

Thank you guys for your interest.

Lawton, you can see the clamps at the bottom. In Europe, you can buy them here: https://www.fohrmann.com/de/loethaken.html
The adjustable stops, which are also very useful, I made myself.

Russ, I had the buffer plates printed up at Shapeways. The material is Fine Detail Plastic. I also thought about having them printed/cast in brass. But I'm afraid that the font would have been less good. The font is 1 mm high and 0.3 mm thick.

Bernard

Bernhard, that with the adjustable stops is also a good tip, so I still have to build. Very interesting to follow your construction technique.

Excellent. In all modesty, I believe I could probably model the matchstick about as well,
but that's as far as it goes. Smiley

Thanks for your interest and your comments.

Chuck, you have to be strong now. I'm about to show my slightly simpler version of a Fordson tractor.
I used the resin kit from plusmodel again.
