Bogie Wheels ready for Collection
19/03/2019
  Highslide JS
  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.
   
Spring Links

  Our members continue to sponsor small parts and here are a set of spring links. The four longer ones (to the left of the drawing) are for the bogie. The remaining 12 are for the driving wheels. Although we are focussing on procuring bogie parts, it made sense to get the driving wheel links cut at the same time. The links will now need to slots cut into them for the spring cotters to fit in. This will require machining as the slots have a fine tolerance.
   
Cannon Box 3D model complete
14/03/2019
  Highslide JS
  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.
   
Design - Bogie Components
05/03/2019
  Highslide JS
  Our design team are busy working on the Computer Aided Design models for the front bogie. We have most of the British Railways drawings for the bogie components; a CAD model usually is a great help to potential suppliers. One problem area is the axle cannon boxes which were supplied by Timken, most of the other components were designed and built in BR workshops. The cannon box is a single steel casting comprising of 2 axle boxes separated by a tube. The axleboxes contain taper roller bearings for the axle to revolve in. The cannon boxes were originally lubricated by oil but this was changed to grease. Once we have drawn up all of the components in the cannon box, we will get our CAD models checked by Timken befoe proceeding to manufacture.
   
Cast Frame Stretchers ready for Assembly
04/03/2019
  Highslide JS
  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.
   
Tender Doors

  Highslide JS
  Ashley Shimwell has sponsored a set of tender doors - both sides - which we've had cut by a local company. Here you can see the left hand set, complete with the rubber sealing strips at the bottom. We've lots of small parts that need sponsoring, please get in touch if you can help.
   
Middle Stretcher Machining Finished
25/02/2019
  Highslide JS
  This was the final step in the machining of the middle cast steel stretcher. Not long after this photo was taken, the stretcher was lifted off the machine, ready to go to the assembly area. Here Keith and Alan from the SSLC engineering team discuss with CTL Seal "spot facing" of the stretcher. Spot facing ensures that the fasteners (here a nut and washer) sit on a flat surface rather than the rough metal of the casting. 4 spot faced bolt holes can be seen below the machinist's right hand.
