I spent a nice Saturday afternoon sanding and cleaning..
I removed the Z Axis hand wheel bearings and shaft assembly first..
Again, unfinished, you can see how the paint around the flange mounting face has not been removed, and it’s uneven, so this will cause a slight misalignment in the flange and may over time cause irregular wear, it may also make the raising/lowering action of the head uncomfortable as there could be slight binding..
The part of the shaft that runs through the base also shows signs of rust..
