Investigating the wheels Rotor Wheels photos
A day of applying Denso tape and paste to the faying surfaces of the old and new turntable rings, and the 3mm packings that lay between them.
Faying surfaces are the contacting surfaces or faces of two similar or dissimilar materials placed in tight contact to form a joint. They are mating surfaces that contain a sealant in between them during any assembly process so that there is no gap or crevice left between them.
They are used in engineering fastening and joint development of different members to form a strong structure. To prevent corrosion between the two surfaces, primers or sealing agents are used to provide an air- or moisture-tight joint. In this case we attaching a corroded wrought iron surface to a new steel ring using aluminium packers.

Ian making sure that the whole surface is covered in paste.
Note that the turntable is virtually sitting on its wheels again

It is quite difficult to apply the paste in a confined area. Note the corrosion, and protective paint.

Note the jack in the background. The new ring sags at the moment enabling the paste to be applied.
Compare the height with May and June 2019

Used a bollard for dockside restraining chain. Chain no longer needed now bridge lowered onto its wheels
Brunel Swivel Bridge
Used a girder for other restraining chain, which was rather long and heavy
