The break was extremely difficult to find.

At first inspection everything looked just fine. I began to wonder if the problem was simply caused by cable adjustment and that in my blundering idiocy I forgot to check the adjustment.

But when I began to put the various parts back together and played with them I noticed the smallest planetary system was difficult to rotate. With a sharp pick I began to probe each gear groove to see if a tiny piece of grit was lodged in one of them, until I found one groove that felt very rough. To the naked eye I could see the groove looked a bit wider than its neighbours, and a magnifier showed the problem.

Nikon Coolpix did the rest.
