Another view taken on May 06th, this time from the front.
Most of the workshop time has been taken up with the re-tubing of our other loco 46512. The work that has been carried out 5025 has centred on the cylinders and motion. Here the piston rod has been attached to the new piston head.
A new set of piston rings are being fitted.
This picture shows the piston having been fitted into the cylinder bore.
The rear of the piston rod protruding out of the rear of the cylinder. It is being lined up with the cross head, when the two slots line up a cotter will be driven in to secure the two pieces.
The cross head and piston rod are now connected.
On the rear cylinder cover the piston rod seal housing has been fitted.
The cross head lower bracket has also been fitted.
The piston rod for the left hand side awaiting the fitting of the piston head. Both piston rods have been machined true before being refitted.
This is the valve piston ring pot. The pot is machined externally and internally to the size of the valve rings, following which the individual rings are then cut.
These are the valve spindle cross head die block guides. These have been re-white metalled and are awaiting machining. They can be seen finished and fitted in an earlier picture showing the cross head and piston rod.
These are new bearings which have been tinned (a light coating of white metal) ready for the addition of the body of white metal which will form the bearing face.
These are the cylinder front covers. They are awaiting non destructive testing to check for defects.
The valve spindle cross head die blocks again, now fitted.
New valve heads have been made. This is one of them in the lathe being machined to size.
Fittings added on and around the cylinders

Another view of the right hand cross head with lower bracket.
The left hand cross head having been machined. At the rear of the cross head, right hand side in the picture, an additional piece of metal has been added. When built in 1934, 5025 was fitted with a cross head vacuum pump. It is the trusts aim to restore 5025 to as near as possible to an as built condition. This extra piece of metal added to the cross head will have a bracket attached to it, which will hold a vacuum pump.
