A key point in the frame assembly started today when the cast steel frame stretchers went into the machining area. Here members of the Clan Project engineering committee discuss the machining requirements with CTL Seal staff. The cast steel stretchers were a design change introduced with 71000 Duke of Gloucester and specified for the lot 242 Clans. The Britannias had suffered from frame cracking and the cast steel stretchers were introduced to provide more strength in a key area. The stretchers will be machined to ensure that they are completely square to fit precisely between the frames
Machining in Progress
Machining of one of the cast steel frame stretchers is now well under way. Here you can see that the face that abuts the inside of the main frames has been machined. The circular disk you can see on the left hand side is one of two where bearing housings for the brake shaft will be fitted
Sam from CTL Seal working on the Combined Frame Stretcher, Spring Bracket & Brake Shaft Carrier. There's a lot of work that has to go into the maching of this component and it's got to be right! Meanwhile, the working party today managed to identify more parts required for the frame assembly. Also, we had a meeting to discuss the frame assembly procedure and, more importantly, the alignment checks that we will need to do before the hornguides are machined.
