Great work, very impressive! And those CAD drawings too -- you could just about build the real thing from those.

Thank you for stopping by again.

I don't want to bore you too much with the production of the countless individual parts. So I will show you only some of the most interesting ones.

For example the etched parts from 0,3 mm brass sheet ...

... and from 0.2 mm brass sheet. Difficult to photograph these shiny sheets.

[Bernhard]

As already mentioned, the 3D printed parts were printed by a service provider recommended to me by Volker. The quality of the printed parts is excellent, that of the first photo unfortunately less.

For the turning plate, I had to turn the outer ring and the hub.

[Bernhard]

Subsequently, the parts were soldered together.
In the plate I provided several small position holes, for the exact placement of the A-frame and the various bearing blocks.

Here are two nice turned parts: a small pulley and the capstan drum for driving the bucket arm. The turning tool in the second picture has a width of 0.5 mm and a radius at the front.
