Here are the diary entries for this month. You can use the forward and backward links to see the next or previous months. Most photos taken before 2018 are small size. From 2018 onwards, most photos you see below will have a link to a full size image by clicking on the photo.
If you look at a previous item on the horizontal stretchers you will see that a bit of manoeuvring was required for the horizontal stretchers in order to drill the fore and aft holes. This work is now largely complete with only the fore holes on the stretcher sitting behind the smokebox saddle to complete. Once this is done, the dimensions of the 3 packing plates (to take up any gap getween the horozontal stretcher and a vertical stretcher) can be checked and the packing plates sent off for machining so they tightly fill any gaps. The packing plates are part of the original BR design.
Tender Wing Plates
One of the small jobs that is being processed is the manufacture of the tender doors and supporting components. Ashley Shimwell is painting the tender wing plates that are fixed to the tender tank front and provide the hinge points for the 2 tender doors (per side). CTL Seal have welded 5 triangular gussets to the wing plates. These, and the edge of the wing plate, will be welded to the tender tank front.
Front View of Frames
Not a lot of progress to report on the frames today as CTL Seal have to fulfil an urgent order for 6 oil rig anchors. We thought that we should take a couple of photos from the front of the frames. Here's Mike Sedgley and Keith Greenhow checking the bogie bolsters. The rod at the front of the frames is a temporary stay just to ensure that the frames are the right distance apart. We will be sorting out the buffer beam area once the hornguides have been machined.

Another view directly from the front of the frames. Below the smokebox stretcher is the bogie pivot stretcher.
Tender Door Parts
As well as big parts, a Class 6 loco has a lots of small parts! Mike Sedgley has been working on the tender doors - these parts are for the door latch
Torque Wrench Setting
Today we've had a discussion on torque wrench settings. As explained in the Construction | Design section of the website, we are using fitted bolts instead of cold riveting. In this situation, the bolts are acting as dowels and a strong clamping force is not required. We use Philidas locking nuts to lock the nut onto the bolt. Here Anthony Pilkington gets stuck in with the torque wrench and applies the agreed setting!
Front Firebox Support
One of the tricky areas for bolting is the front firebox support. The liner in the foreground is fixed to the stretcher which also provides the pony or trailing truck pivot. Sitting on this liner is the front firebox support shoe, attached to the bottom front of the firebox. The shoe is free to move on the liner as the boiler expands with heat. The wedge shaped component provides a restraint to a top face of the firebox shoe and must be adjusted (according to the drawing) so that 'a clearance of .010" between these faces to be worked when the boiler is under steam'. We're going to need to fit a countersunk bolt head here so that the wedge can be adjusted.
More small parts. These flexible hose connectors, made for us by Generic Engineering in Rotherham, are for the 4 flexible hoses that provide an oil lubrication feed to the bogie centre slide.
Fitting Frame Bolts
Prior to hornguide machining, we need to fit a small number of key bolts to ensure that the frame alignment is locked. Here the CTL Seal team are fitting the bolts that fix 2 of the horizontal stretchers to one of the vertical stretchers
