2 February 2017

The outside of the frames in front of the right hand cylinder was inspected in detail this week. The cutout for the conjugated valve gear is shown in the picture. It looks like when the cut off was increased and more valve movement was required the cutout was made bigger by the use off a gas axe.

The horn castings were examined for cracks this week. The top corners are areas likely to be affected by fatigue cracks. The casting surfaces are rough and careful inspection is required. Inspections are always carried out by two people to ensure nothing is missed. This is the right leading horn casting viewed from inside the frames.

22 February 2017

Set up for riveting the dragbox rivets. The rivet is tried in position cold. It is jacked with a pneumatic piston, we call a jamback, packed against the front of the dragbox. Once the setup is finalised the rivet will be heated and fitted. The rivet is 7/8" diameter.
Photograph: Darrin Crone.

22 February 2017

The special large head countersunk rivets for the splasher brackets. The long ones for where the frames are of double thickness. One has had 3/8" cut off ready for fitting. The length is critical to give sufficient material to fill the hole in the frames and form the correct size head.

After fitting the rivet heads are ground flush with the frames. Bob Shearman grinds the heads but the photo also shows how the footplating prevents access for the rivet gun from this side of the frames.

15 March 2017

The safety links removed for inspection. The long holes are pinned through the locomotive dragbox and usually take no load. If the main drawbar between the loco and tender breaks the safety links maintain the mechanical connection of the loco to the train. This allows the train to be taken to a safe location where the locomotive can be removed.

19 March 2017

Recently the bogie has been low on our priorities as manpower has been diverted to painting the frames and components. It has also not been in the best of locations to work on as it was moved to allow the repair of Rocket's boiler. This week needle gunning of the frames resumed with the outside of the frame plates completed.
Photograph: Darrin Crone.

19 March 2017

To remove the safety links and main loco-tender drawbar the tender floor was removed. The main drawbar is laid across where the the tender floor was. The end of the drawbar sits on a solid cast iron block intended to balance the tender, as the empty volume of the corridor needs to be balanced with the other side that is loaded with water and coal.

Though we have had no trouble, it is known for stays in the combustion chamber area of LNER wide firebox boilers to be subject to breakage. As a precaution it was decided that the stays in the sides of the combustion chamber should be replaced at this overhaul. As part of the replacement procedure the old stay heads have been removed.

A corner section of the bogie centre casting. The bogie is upside down so the bottom of the bogie is at the top of the picture and the rivet heads secure the casting to the left hand bogie frame plate. It can be seen that the corners have been extended to give the frame plate extra support. Existing rivet holes were welded up and new rivets put in when the corners were extended. The new sections are marked on their edge 2553.

The Sir Nigel Gresley Locomotive Trust, working in conjunction with the National Railway Museum, today held the first "Object Handling Day" event of the summer. Various components and tools were made available for the NRM visitors. Excellent talks were given by Malcolm Bateman, SNGLT Editor and Trust member, on the history of the locomotive and the progress of the current three-year overhaul taking place at the NRM.

The air pump steam cylinder has had the end flanges and lead in to the bore re-machined. Holes at either end, filled with weld required drilling and tapping. This was done on the NRM's Richmond radial arm drill.

The tender is now next to the loco, at the buffers so will not be in the way of future shunts in the workshop. As we don't now have to keep the tender mobile it's overhaul can now start in earnest.

The bogie centre casting has a number of bearing surfaces that require measuring for flatness, height and squareness. It has been put up on the marking out table in the NRM workshop so that this process can be carried out accurately.

The clutch grips the reverser shaft by closing on to the sheaves shown in the picture. To ensure the sheaves don't rotate on the shaft they are keyed. The key is shown protruding against the shaft.

The right hand piston head has been built up with weld and is on a Dean, Smith and Grace lathe at the works of K D Flavell to be machined truly round and to size.

An image taken of a roof stay by the endoscope.The thread on the end of the stay goes into the firebox crown sheet. The condition of this stay, apears to be very good and it looks to be suitable for further use, however some stays will be removed to examine their condition inside the plate.

Two spotfaces were cut on the right hand combined brake shaft and spring bracket. The welds on this fabricated bracket are larger than the radius in the corners of a casting so have to be cut in to to provide a clamping face for the bolt that will be fitted in to the hole.

The coupled wheel axle boxes are being put on the marking out table at the NRM, York. The disc in the centre is exactly the same size as the axle journal that runs in this bearing. Measuring from the centre of the disc allows the position of the axle on the locomotive to be calculated. This is important as when the axleboxes are re-metaled the centre dimensions will need to be known accurately.

The safety valves were retrieved from store this week. They will be stripped and examined for condition.

The air pump governor is now completed. The governor regulates the steam pressure going to the pump which in turn determines the pressure of the air the pump generates.
