so have had the new column made by a local engineering company it was turned from a solid piece of mild steel, has a 28mm hole with clearance in the middle the machining for the bearings at 35mm to the specified depths to accommodate the shaft.

the column was then welded for the mountings to enable it to be bolted to the cross member under the scuttle.

the existing stalks were used and just held in place with threaded rod.
