[TowerTalk] Ham IV bearing balls

[Floyd Sense]

You might also want to take a close look at the bearing races.  I acquired 
an old and apparently abused Ham IV last year and the bearings didn't look 
good.  When I cleaned up the races and looked at them closely, they were 
badly dented from the bearings.  Apparently the rotor had been overloaded, 
damaging the races.  Unfortunately, the races are simply cast into the 
ALUMINUM housing and are not very forgiving.  I was able to buy replacement 
housing castings from the usual rotor parts sources for a reasonable price.
