Follow along below to see how you can fix the glasses with common household items and materials. The only special tool needed is a small gauge drill bit. I got mine for less than three bucks at a small town hardware store. If you're willing to take a risk and trust your skills with simple hand tools, you could have fixed glasses as soon as tomorrow!
Step 1: Things you'll need
Step 2: Lecture on gluing technique
Cleaning, Clamping and Curing.
Cleaning: you want the surfaces to be joined to be very clean and dry with a matte texture. The glue needs a solid, clean surface with a little "tooth" to bond to. Sanding lightly with fine sandpaper and washing with a household solvent should do the job. Let the parts dry thoroughly before gluing.
Clamping: You want the parts held steady relative to each other while the glue sets up. If the parts wiggle while they're bonding together, the bond is weakened.
Curing: This means giving the glue time to do its job - form a bond. If you strain the bond before it's fully set up, it will be weaker.
So, clean the joint well, clamp the parts together, let the glue cure and you'll have good results every time.
