Thanks Alistair.  The thread in your link never really gets to caster,
but toward the end he gives a link to the revised thread which does.
His procedure helps me make some sense of the info in the Bentley
which lets you check caster indirectly thru changes in camber at 20
degrees left and right.
  I think I'll go buy a digital level today.
