Fitted one side of the system, as took longer than I expected. Having a damper blade really made fitting the lower one really tricky.
What was the problem (I have blades so forewarned is forearmed!)
When screwing in the lower swivel joint in place the nipple, when fully screwed, the top of the joint rubs against the bronze plate. Also very tedious trying to tighten the fitting with an open ended spanner. I had to inch it around a few mm at a time I installed it as seen in Craig jazz's photo as if it pointed upwards, then when the wheel turns, it would rub against the bronze plate as well.
