Hoist Gantry
08/07/2024
  Highslide JS
  Over the years, the project acquired this hoist gantry. Keith and Alan have modified it by welding in new triangular brace struts; this should make it stronger. We've also added 2 pairs of really solid castor wheels to help move it around.
   
Bogie Frame Welding
08/07/2024
  Highslide JS
  3 welding jobs were completed on the bogie frame this week.
  • Red Arrow - The ends of the frame stays were welded into the bogie frame

  • Green Arrow - The grease nipple mounting plates were welded onto the "arms" of the stretcher. 5 grease nipples on each side provide lubrication for the hornguides (4) and the base of the bolster cup.

  • Blue Arrow - The bearing spring pads (which are fitted from under the "arm" of the stretcher) were welded into the stretcher.

The white marks are the residue from the post weld ultrasonic testing.
   
Driving Wheel Patterns
08/07/2024
  Highslide JS
  The pattern for the central driving wheel is now almost complete. Will has developed the 3D model for the pattern and is able to see the results of his efforts in the pattern shop at William Cook Cast Products Ltd.
   
Driving Wheel Pattern (2)
08/07/2024
  Highslide JS
  The size of the pattern is more obvious when stood upright. Gary, on the left, from William Cook's has been working on the pattern. The wheel is 6ft 2in in diameter or 1.88m in modern speak! The pattern will be lightly larger due to a shrinkage allowance when the hot metal cools.
   
Coupled Wheels Pattern
04/07/2024
  Highslide JS
  William Cook Cast Products have reported that the first of the 2 coupled wheel patterns is almost complete. They expect to cast the first 2 wheels in mid July, Note the ribs at the bottom of some of the spokes. These support the plates which will contain the lead balance weights. For casting, additional material is added to the pattern so the ribs look more prominent. After casting, the ribs will be machined to the correct profile.
   
Cylinders and Valve Gear Design
19/06/2024
  Highslide JS
  Will has been working on developing the 3D model of Hengist's cylinders and valve gear. We intend to adopt the same modification as recently installed on 71000 Duke of Gloucester whereby an extension cast into the rear cylinder cover provides a support for the front of the slidebars. In order to create the new design, we need to model the existing BR design where the front of the slidebars were not supported. We know from Bill Harvey's book (shedmaster at Norwich in Britannia days) that there was movement at the end of the slidebars. Will has modelled the rear cover, swab mop case and slidebars. He has started working on the piston valve heads in the steam chest - above the cylinder.
