Build an Excavator from Scratch

[pufferfish]

Still working on the rotary drive.
Today the outer clamps and their flanges to the platform were built.

Befroe that, the old flanges have to remove from the platform. i've used the little 35 mm cuttings discs from proxxon.



The outer clamps get some recesses for the weldable flanges with m4 threads.



After this a first setup of the mechanism happens





works fine but needs some more details before completed....
