Placing the teak boarding on the interior walls of the second of the two saloons of Barnum no.228 came to an unexpected halt recently when it was discovered that screws retaining two of the main forged steel brackets retaining the side of the carriage to the main members had corroded within the frame and had to be replaced. The sides had sprung no more than a few millimetres but it was vital to restore with a tight connection the full integrity of the structure.
When this Barnum was first delivered to the Ruddington Heritage Centre, many but not all of the vertical body timbers had rot at their bases due to water ingress over a long period. This required a great deal of remedial work, to cut out and splice-in new lengths of U/S Redwood, a particularly tough and water resistant but softwood timber which was then re-attached to the massive steel joints.
The latest remedial work, led by Peter Wilson, was first to drill out the time-hardened screw heads and then to drill for retaining bolts which met with steel reaction plates, machined and affixed to the outer side of the vertical body member affected. Once set up, the retaining bolts are tightened over weeks until the whole side is back to its correct alignment and the joints secure once again.
Then it is hoped that the delayed teak panel work will be resumed in earnest and the setting out commenced to establish the four cloak closets.
