Laygear clip removal

["A. B. Bonds" <ab@vuse.vanderbilt.edu>]

I am currently righting the wrong of the DPO having put 90 wt in the
gearbox.

How does one remove the circlips holding the roller bearings in the
laygear?  There are no handy openings for a clip removal tool.  The
best I can imagine is constructive use of a Dremel to weaken the clips
at a couple of places so they can be permanently deformed enough to
twist them out.
