Another day mucking about with the rear derailleur.   Mildly frustrating day without too much progress.   Spent a bunch of time hunting for a new shifter and replacement cables.   Eventually just gave up and bought 2 lengths of shifter cable housing in an attempt to eliminate possible shifting problems.

By the end of the day, the bike was rideable.  It was possible to get into and stay in all the gears, even if it wasn’t all that smooth.  Gave it a second thought to take it home for the weekend, but figured it was still rather sketchy.   I should clean up at home so that there is a place to put the thing too.

Hoping to have a functional bike soon!
