The proper solvent will give you a permanent weld. Methyl Ethyl Ketone,
Chloroform (everybody has a bottle of that around--smells funny) or my
personal favorite, Methylene Chloride (slightly carcinogenic). I have a
bottle of "Proweld" by Ambroid which works great. If you really want to get
exotic, get some Tenax 7R--I don't know exactly what it is but it welds
styrene harder than the original plastic and is gone in 5-10 seconds (it
also has an annoying habit of disappearing from a tightly sealed bottle!).
Toluene-based cements take forever. Where was this stuff when I was a kid,
waiting for that damn airplane glue to dry? Oh, the heartbreak it would
have prevented.

A well-stocked hobby shop or plastics distributor is your best bet.
