And it took about 15 minutes. Well, say 45 minutes, taking pictures and getting superglue everywhere. I'm actually typing this one-handed whilst my other hand is stuck to my desk (yeah yeah, withhold your dirty jokes).
Anyway, parts needed:
1. Super glue (or super gel, 5 minute epoxy, etc)
2. Pocket knife
3. Sandpaper, 150 grit or so
4. wire cutters
5. needle nose pliers
6. shrink tubing (black) multiple sizes are nice but not necessary
7. Carbon Fiber strip
8. Soldering Iron
9. Busted glasses (though you could beef up your undamaged glasses, for that uber nerdy look)
The carbon fiber can be purchased at any RC Plane hobby store. Just ask for carbon fiber spar material. The stuff I used was about $7.00 for a 24" strip, and it's about 1/8" wide, and maybe 1/16" thick. Sorry, I misplaced my calipers. And no, I didn't go buy this, I had it on-hand because I have an RC plane hobby (YouTube 'intrepid1' for my in-flight videos...)
I picked up the shrink tubing in a whole kit of sizes from Harbor Tools for like $10 a few years back. Handy for RC planes. and fixing glasses apparently.
Optional: Accelerator (Loctite 712) that I use. (helps superglue set faster)
NOTE: This instructable will not allow your glasses to fold up. This is simply a (hopefully) long-term solution to repairing your glasses!
