How To: C15a Wire-3 restoration

[David Herbert]

Tony,

What a nice drawing, showing most of the possible orientations. As you say, the wire is there to stop the bolts unscrewing so ideally should be in tension on both sides of the bolt head if the bolt is trying to undo. Another way to look at it is that the wire between two bolts should be trying to tighten both bolts as it is under tension. Otherwise one bolt undoing is trying to take the next bolt with it.

Bob,
I was taught not to use molly grease on anything with ball or roller bearings as it is so good that it can make the balls/rollers skid rather than roll. Quite what harm this would do was never explained as it seemed to me that any flatspotting would need metal to metal contact and that would make the rollers roll way before any harm was done. Maybe some sort of partial skidding was meant but what do you think ?
