Investigative Work in 2017

The main focus of our attention was the badly pitted wheel track which sits on top of the wheels.
The wheel track is a heavy forging (about 14 ft diameter) probably made by rolling to a circle and fire-welding the joint.
It is an amazing example of heavy forge-work which should be preserved for future generations.
The problem is how to machine away the face, which is why a little experimentation is needed.
Bob found that following measurements today, he thought that he would put them on a record to compare with the original intended dimensions of the rail track.
The original Brunel drawings show a radius to the centreline of the rail track as 6ft 7.5in (79.5in). We are therefore very close when we average the N-S and E-W dimensions acquired on site today!
