The vertical arms

Both vertical arms have been constructed, the longer being 9 feet long and is shown below:

Visible in the above picture are the bearing boxes for 16 four inch diameter aluminium pulleys which allow the main bucket-wheel arm to be raised and lowered by cables onto 2 winding drums at the far end of the counter-balance arm (which has yet to be built).

The 2 vertical arms can be clearly seen to the right of the bucket-wheel
