David Andrews Princess Royal – full motion running milestone

A few more micro fixings later saw. a major milestone both mentally and build wise.

These are the pins which hold the eccentric rod to the bottom of the expansion link. Initially I made the two fully threaded versions but then realised that it would be better if they were only partially threaded (14BA).

I had already fitted the return cranks and after this it was a short step to getting the full motion running.
