The picture shows the front and the back of the new pattern, collected from expert pattern maker Brian Oldford by our engineer Geoff Turner. This is one of the three major cast frame stretchers incorporating the main spring hangers. The red areas are as they will appear in the finished casting. The areas painted yellow indicate the parts of the pattern that will be machined to the exact dimensions on drawing SL/DE/22042 ensuring everything lines up with the frames during the ensuing erection process. The black areas are where the core boxes are installed in the mould to form the internal profile. There are 16 pieces which make up the pattern and 3 core boxes. The pattern has two split lines in the mould which means 3 boxes, a drag box (on the bottom), a cheek box (in the middle) and cope (on the top). This is by no means a simple casting. The pattern has been safely placed in store while we await quotes from the several foundries contacted with a view to pouring the casting shortly.
