[TowerTalk] Yaesu GS-065 thrust bearing

[Grant Saviers]

McMaster has balls in stainless, 304, 316, and 440.  316 isn't the 
hardest but is the most corrosion resistant.  They are what I use for 
rotator rebuilds.

If you meant "cratered" which happens when the mast oscillates then it 
might be possible to smooth that out a bit with sandpaper since the 
bearing is pretty crude to start with.  Works for rotator races.  Adding 
a couple of grease fittings which get a shot of grease every year will 
also help a lot.  I like the TFE loaded full synthetic "Super Lube" 
formerly by Synco, now owned by Loctite.
