Stuart,
I certainly agree that there should be no potential difference between the
case halves but, what about the potential difference between the left
(grounded) head and the case?  There are numerous things that tend to isolate
the case halves from the head.  That big rubber gummy for one; the sealants
and oxides at the interface of the head and head nuts for another.  So, maybe
we all should be installing grounding bonds between the lower cases and the
heads.  What do you think?

As an aside, I once braided my own grounding strap from stripped 14 AWG SO
cord.  It was on a Sunday before we had such things as 7 day-a-week supply
houses.  I used a plaiting as sailors do with rope.  I formed the lugs out of
sheet Cu and used soft silver solder.  When it was finished, it probably was
better than factory because I didn't mind using an extra 10 cents worth of
Cu.  Ah yes, were there is a will, there is a way.
