However, it wasn't Steve Tillett, or at least I don't think it would have been...

The story as I got it from Bronnie was that two non-Club members addressed the Club at a meeting an announced their intention to start camshaft grinding, for which they'd acquired a machine. It was they who went to the Norman household and saw Bill walking on the piano keys, and for whom Eldred retrieved a very dirty cam from the pile of rocks.

What a wonderful subject Eldred was for a story, and how good are the extra details that 'Harv' has in that thread.
