Per KenK:
Saw a new - to me - gadget in a newly arrived catalog. "Lazer Bond Rapid
Repair Welder". Supposed to work with most materials. Put a dab of resin on
the joint to be glued, then zap it for three seconds with the included UV
battery-operated laser. $10. Doesn't say how much resin is included or if
resin refills are available.

Sounds like what my dentist uses when he puts in a filling.

Stuffs it with white epoxy goo, hits it with a UV light... and the stuff
goes off within seconds.
