I am nearly at the end of the suspension. The last bogie is all stripped and the springs, rods, balls, cups, washers etc have been cleaned of rust and painted, ready for assembly.
The idler wheel bearings were in excellent condition so the wheels, once cleaned of solidified grease mixed with dirt (making something akin to concrete), only needed modern seals to replace the old perished cork seals.
I am still waiting on the engine machining to be completed and the re-rubbered wheels to arrive.
Here is the spring and rods prior to cleaning and painting and the other front bogie installed.
