Stumbling

Stumbled about for a bit trying to figure out the rotating part of my device. In the end opted for the screw and two elbows from a scissor jack. That worked OK, but still no definite signs of what to power the thing with. While I massaged the brain on that I hauled things about to clear up som eof the metal detritis under one of my shelf areas and in the process pull out any bits and bobs that might come in useful.
