Axlebox and Spring repairs

Next, I moved onto the springs and hangers. Several of the dampers had become detached from the springs. The white metal pins are the vulnerable parts so I decided to replace them.

First, I cut off all the dampers and pins from the springs. Next, I used a burr that came with a set of tools for the Dremel in the mill, to mill out the remains of the pin between the frame of the damper. I had to slow the mill down to 320 rpm in order not to over heat and melt the white metal.

I used a clothes peg to hold the springs to drill them again using the mill.

Drilling the Springs for new hanger pins

I cut lengths of brass rod to replace the white metal pins. I made a jig from a piece of ply with a blob of bluetac and a hand vice to help with soldering.

Not the prettiest of soldering but they look a lot better.
