Smoke Deflector Work (2)
  Highslide JS
  Bob from CTL Seal preparing to weld the feather edge beading onto the outside of the left hand smoke deflector. Bob will be welding through a series of holes around the outside of the plate through to the rear face of the beading.

SSLC have now placed an order for the machining of the bogie cannon axleboxes. This also involves the welding of manganese steel liners onto the outside of the casting. These provide the rubbing surface against manganese steel liners on the axlebox guides which are fitted to the bogie frame. We have no drawings, other than the arrangement drawing, for the internal components within the axlebox, so we have had to reverse engineer these components from the arrangement drawing. Our drawings are now being assessed by Timken.
Firebox Support Stretcher
  Highslide JS
  We are getting close to an acceptable fit of the firebox support stretcher up against the bottom of the main frames. CTL Seal have devised a framework so that the jacks can push harder against the stretcher. In the photo, Anthony Pilkington from CTL Seal can get a 0.0008" feeler gauge into the gap, but nothing bigger.
Smoke Deflector Stays
  Highslide JS
  Thanks to our members for supporting a mini appeal we issued recently. These are the stays for the smoke deflectors. They were cut and drilled as flat plates by Specialised Laser Products in Rotherham. Now they have been delivered to Taylor and Watson in Penistone who will bend them to the correct shape. The 6 nearest the camera are the 3 stays per side at the top of the deflectors. The middle 2 are fitted at the centre front of the deflector plate at the 3 o'clock and 9 o'clock positions when looking at the front of the engine. The top 2 require a twist which explains the angled ends. These sit at the bottom front of the deflector plate
Smoke Deflector Handrails
  Highslide JS
  Craig from CTL Seal and Neil from the Monday gang working on the handrails for the smoke deflectors. Here Craig is cutting down the handrail to the correct length so that it fits in the handrail pillar at the aft end of the deflector plate
Measuring for Fitted Bolts (1)
  Highslide JS
  With the firebox support stretcher now fitting tightly up against the bottom of the main frames, CTL Seal have drilled and drilled the holes that go through the main frames, the frame extensions and the firebox support stretcher. These holes are now truly circular throughout the length. Geoff is using a Bowers bore gauge to accurately measure the internal diameter. We can now draw up specifications to get the bolts manufactured.

  This is what the business end of the Bowers gauge looks like. The hole has an internal diameter of 37.062mm
