The New Hotness

  • Eyeglass Spring Temple: Screw Hole Tweak

    A screws in one of Mary’s eyeglasses unscrewed itself, but, miraculously, we found it and I retired to the shop.

    Because the glasses have spring temples, the screw would not align no matter what force I applied to it:

    Eyeglass spring temple - screw misalignment
    Eyeglass spring temple – screw misalignment

    So I just embiggened the hole until the available force did the trick:

    Eyeglass spring temple - hole filing
    Eyeglass spring temple – hole filing

    Dots of Loctite worked into the threads should prevent that from happening again, but I’ve learned to never say never.

    In retrospect, the temple pivots have an exposed slot that I think would allow jamming a block in place after pulling the spring-loaded pivot outward. Temple springs are impossibly stiff and I have previously failed to budge them in glasses without the slots, so I don’t know how well that might work.

    Verily: If brute force isn’t working for you, then you’re not using enough of it.
