Hi Gerard,
I think you misunderstood. I was writing about the removing
and extending back of the LENS, not the extension tube.
I suspect there is a flexible circuit connection leading from
the EF lens contacts and between the various lens motors. See:
http://photoscene.com/sw/tour/inside.htm and
http://geocities.com/Yosemite/8917/inside.html
But your idea of making a tilting bellows with the extension
tubes is also interesting. It would work if you could remove
the spring couplings

and replace them with flexible wires.
Cheers
