Hello MMD readers.  I'm having trouble with the governor assembly
on a quite small cylinder box (5" length cylinder/comb).  I can't get
the worm/endless screw to turn easily when I put torque onto the first
wheel in the assembly, with my finger.

I've followed all advice and suggestions in my various Ord-Hume books,
and played around with the depthing/meshing, polished the surface of
the endstone, re-bushed the top bearing hole which was worn, and
ensured that there is only approx. 1 mm of upward lift on the governor
when torque is first put onto the gears (i.e., that there isn't too
much play), but am obviously missing something.

Might there be wear on the endless thread itself, which is causing
it to not run?  The whole thing moves perfectly freely if I flick the
governor with my finger to set it spinning, but it won't go if I try
to put the torque on the gears that mesh with the endless.  But I'm not
sure where to look, or what to consider next.  I've not encountered
such a problem before (this is about musical box number seven that I've
worked on).  Any suggestions will be gratefully received.

I'd willingly consider sending the governor assembly over to someone,
from here in Australia where I'm based, if anyone was willing to take
a look who thinks they may be able to solve it.  I'd love to get the
box operational for its owners.  Everything else is in good condition
so it's a shame not to solve this problem...
