    I can reasonably solder electronics although I get an occasional cold
    solder joint. I have this pair of glasses I didn't wear much which
    cracked near the temple joint. (The temple cracked). The repair shops
    ask too much, compared to what I paid for the glasses. I tried online
    to find temples, to no luck. So I'm considering soldering it. My
    uncle (a retired EE) told me it would never hold. Part of the problem
    is it cracked very near the screw joint. and so would suffer a lot
    more torque than if it was further back. Any tips?

  2. Yes, buy a new pair of glasses.

    Will it hold? We can't tell you that not knowing what the material is that
    you are soldering. It may be brass, titanium, zinc, or something else. If
    they are junk now, you have nothing to lose so give it a try. Worse case
    scenario is you get a new pair.

    Consider brazing the joint; you may be able to find a hobbyist
    minitorch that uses tiny propane and oxygen cylinders -- Radio Shack
    used to sell these in the States.

    FWIW, I have also made repairs on tiny objects using very low
    currents with a wire-feed welder; build up the repair and grind
    to final shape.

    I tend to be skeptical that solder joints hold well. They're meant
    to provide an electrical connection, not to be a structural component.
    But then I also pretty well suck at soldering.

    Since the glasses are fairly useless as is, why not try soldering
    them and find out empirically how well it works?

  5. You could try a little JB Weld. It might look awful, but it might also work.

    Lead and Tin will not work. I learned how to repair eyeglass frames from my
    Dad working in his office. He was an "old school" Optometrist. Back in the
    day when Jewelry stores had Optometrists. His office was one of the few
    places that repaired broken frames. It requires gold solder and an acetylene
    jewelers torch. Quick and easy if you have the tools. It will discolor the
    finish some. If you attempt any other method, it will not work for long and
    they will be rendered un-repairable. See if you can find a good Jewelers.

  7. Any tips?

    Cannibalize dollar store readers for a replacement temple piece.

    You can braze with propane or MAPP and air.

    A soldered butt joint won't typically hold, but it may work if you
    splint with a bit of steel or stainless wire there (any old guitar strings
    around?). You can gammon with fine Nichrome wire sold for ignitors on

    How about taking it to a jeweler who can use a harder, stronger kind of
    solder and is familiar with metals other than the ones we ordinarily work
  9. For the cost of hiring a jeweler to fix the frames, it's quite
    likely he could buy a new set of glasses.

  10. Have you priced prescription glasses recently? I wear a progressive lens
    with anti-glare coating and darkening lenses. Typical price is about $400.
    $500 at one place I checked. Actual cost is probably $20 in material.
  11. JB weld may very well do the job. The other option is to net search Zenni
    Optical, they are out of Hong Kong. You likely have your prescription, they
    will cheerfully sell you eye glasses cut to your Rx. You won't believe the
    prices, and the glasses are light weight, but I was pleased with the optics.

  12. What's a good right wing Republican like you doing with Progressive glasses?
    That's just another word for liberal, you know.

    True, but the OP could use the original lenses in new frames. There's no
    law that says a frame and lenses must be sold together.

    Solder would never hold, those frames are typically brazed. You can
    certainly re-braze them, though you would potentially also need to
    re-paint / re-finish them afterwards.

    They keep changing frame shapes to prevent that (more profits). The
    lenses may be perfectly fine, but it's very likely you won't find new
    frames of the same size and shape if it's more than a year or two old.
  17. They were sold to my under Hillary's health care plan. I see the world
    differently now!

    Your uncle's right. Eyeglasses frames are brazed, not soldered. Last time I
    had to get frames repaired (about 5 years ago), it cost $25, which is a *lot*
    cheaper than a new set of frames.
  19. Try (I got my Flexons from them, then had Costco grind
    and install the lenses.) If the frame is still manufactured, they'll
    probably be able to find it for you, or a frame that has the same lens

    Another possibility is to contact the frame's manufacturer. They might be
    able to supply an exact-replacement temple (or a compatible one).

    When my mother's frames broke, the first shop we went to said they
    didn't have frames to fit her lenses, but they could do both frames and
    lenses. When I said we go someplace else, it was amazing how fast they
    found a pair of frames that fit.
