I spent most of this afternoon with soldering iron, files and a 'hold and fold'. My 'Traction Ears' now slide smoothly in my 'Traction Horns' and even the job of dismantling the Bachmann chassis and modifying the gear drive was only made difficult by not being able to find a sharp drill that could cleaning cut the rather soapy plastic of the bogie easily. So far I am vary impressed with how this is going together and I'm looking forward to the 'rolling test' to see how the springing works.

The picture shows from back to front, the spur gears, the modified bogie drive units and the two parts of the sprung bogie, each made up from the Penbits etch.
