The New Hotness

  • Silhouette Eyeglasses: Second Temple Repair

    As we expected, the remaining temple of Mary’s Silhouette glasses broke, a bit over a year from the previous repair, and this repair proceeded along the same lines as the previous fix.

    Cross-drill a brass tube for the teeny screws:

    I don’t recall having to do quite this much filing to make the screws fit, but they don’t call ’em “needle files” for nothin’:

    Trim the tube to the proper length by chucking it in the Sherline, rotating the spindle by hand, and filing a notch just below the jaws:

    Then file the end flat, countersink it just a bit, and ream out the hole to fit the broken end of the earpiece. This one didn’t quite fit the tubing, but we’re talking a few mils of tolerance on a bent piece of titanium. Rough up the end of the earpiece, degrease everything, and a few dabs of epoxy suffice for another Steampunk repair:

    The original fix continues to hold, but … this can’t go on.
