    A pair of antique collectible Cordomatic reels get occasional use in the Basement Laboratory:

    Cordomatic 500P reel - installed
    Cordomatic 500P reel – installed

    The extension cord reel didn’t latch reliably when needed, so …

    There’s an obvious screw on the other side and a non-obvious screw hidden in the obvious place:

    Cordomatic 500P reel - hidden screw
    Cordomatic 500P reel – hidden screw

    The electrical contacts were in good shape, although I smeared the grease around the rings just to make it seem like I did something:

    Cordomatic 500P reel - contacts
    Cordomatic 500P reel – contacts

    The ratchet pawls hide under a riveted cover:

    Cordomatic 500P reel - pawl cover
    Cordomatic 500P reel – pawl cover

    The duct tape shows I’d been in there once before, likely for the same problem, and had already drilled out the rivets.

    Alas, I forgot to take a picture after removing the cover, but the general idea is to put just a dot of oil on the pivots (which, as you’d expect, are the rivets), wiggle everything around, and reassemble in reverse order.
