  The shutter is held together by a retaining ring around
the lens mount. The ring is adjustable and is in turn kept
from turning by a very small set screw. Take the front cell
off the shutter and look to see of the set screw is missing.
They are hard to find.  If its missing the ring can be
tightened and locked down with a drop of Lok Tite at the
edge. You can tighten it with you fingers.
  I have the Compur repair manual but don't remember any
spec for how tight the ring should be. I tighten them
enough to give the detents on the speed ring a definite
feel. The speed ring will have a very slight play even when
adjusted right.
