    All:

    Does the oil cup of a hole jewel go toward the cap jewel side or toward the pinion side?

    Thanks!

    I should clarify, and say the jewel in a capped setting pair has a flat bottom (towards the gear) and curved top towards the cap.

    If you have a flattish jewel with a reservoir it may be a plain plate jewel, not meant for capping.

    There is a good diagram here
    en.wikipedia.org/wiki/Jewel_bearing
    that might help.

    Regards

    Peter
