Question of Balance (rail bearings)

[Newton Hunt]

Contact S&S parts at 718-721-2600 4, parts department Glory Lefrak,
and ask for a set of bearings.  The hole is drilled at a slight angle
so orientation is important.  Replace the felt retaining stirps as
well if they have been eaten.

Leveling the keys after replaceing the bearings is the time consumer. 
You will need leveling punchings, a nice straight edge and some time.
