Pinning on new flanges

[Don Mannino]

Bob,

When I was rebuilding I made it SOP to always ream / burnish and repin the 
shanks.  Get a simple spring type gram gauge from a supply house, and pin 
the full set to 4 - 5 grams friction, measured at the screw holes.  That 
should be a good friction level for 60% humidity.
