I still had bit to much slop in the mesh of the pinion and ring gear so took some pics and video of the fancy turning machine I use for this sort of thing. It is not exactly a computer controlled mill, but you get the idea...
Finished gear after turning down
Installed on the crane
With the track assembly in place
And the video of the turning process
