Plastruct makes a glue (actually a solvent) that works well with ABS
(along with most other Styrenes). I believe the solvent is based on
Methyl Ethyl Keytone. Fumes are pretty nasty, and I believe the solvent
is classified as a carcinogen in California. Use in a *well* ventillated
area.
Works very well - brush a little on, then snap pieces together. The
solvent will flow into the seam due to capilary action, then disolves the
plastic slightly.
Cyanoacryilic glues (Crazy Glue, etc) are OK for bonding ABS to other
materials (slippery engineering plastic used on axles, metal, etc). For
ABS to ABS, however, I prefer working with a solvent.
