Last night, in an attempt to fix a loose temple on my glasses, I found myself in a pickle. As is often the case, it was much easier to take my glasses apart than it was to reassemble them.
I’d taken the temple off my glasses frame to tighten a loose hinge. However, I realized (after dis-assembly, of course) that the spring tensioner in the temple made it impossible to replace the screw that holds it to the frame. Of course, I tried (stubbornly) for about 30 minutes to figure out how to reassemble my glasses. Alas, to no avail.
Eventually, I asked YouTube and found this video.
In less than two-and-a-half minutes, the video producer demonstrated the problem, the tools needed for the repair, showed how the method worked, and then the final outcome—a textbook-perfect tutorial. No fluff, just useful information. Five minutes later, I had my glasses reassembled and back in business.
