All 3 of the cast steel frame stretchers are now in the assembly area with machining complete. It's taken a lot of work to get them to this state but finally they are finished. This type of stretcher was part of the 71000 Duke of Gloucester design and was to be fitted to the Lot 242 Clans. The first 10 Clans had the same frame design as the Britannias; the latter had suffered from frame cracking and this design was intended to correct that fault. CTL Seal intend to set these up on the base frame this week and get them into a rough alignment.
Cannon Box 3D model complete
Having developed the basic casting into the 3D model, our design team have now completed the cannon box model which you can see above. Alan converts the British Railways/Timken drawings from the 1950s into a 2D model. Keith then takes the 2D models and develops them into a 3D model. The grey tubular protrusion on the right is the axle. The 2 strips in brown are condensing vent pipes.
Bogie Wheels ready for Collection
It's been a while since we last reported progress on the bogie wheels but some rework has been necessary at the foundry. We can now report that all 4 bogie wheels are now through quality control at the foundry and are ready for delivery to our assembly base in Sheffield. Here is a pair of wheels.
Preparing Stretchers for Assembly
Ian from CTL Seal fettles up the cast stretchers in the assembly area. Assembly should be starting this week and the CTL Seal team have been tidying up some rough edges from the cast steel stretcher castings.
Keith Greenhow from SSLC's engineering team and Ian from CTL Seal discuss where any fettling of the cast steel stretchers is required.
