There is a product called Cyanopoxy that was written up in the model railroad press a few
years ago. It can bond materials such as nylon and delrin. I haven't tried it myself,
but the reviews are favorable. It is fairly expensive, though. The link is:

 Great that it worked for you, but be advised that acetone will also (in 
 my experience)  turn some plastics into grainy mush, so it's not a

 Yes, methylene chloride is the proper plastic solvent for styrene types. 
 Plexiglass, Lexan, and many plastics will soften with this, and bond 
 almost instantly. Hold for a few seconds to set, then let sit overnight 
 to reach maximum hardness. Doesn't dissolve the plastic other than at 
 the contact point. This is the stuff they use in plastic shops...along 
 with some other solvents. Has anyone found a solvent that will solidly weld the
PC+ABS blends yet? I 
run into various blends of PC+ABS all the time and have yet to find 
anything that will work well. Methylene Chloride will melt the ABS part of 
the blend, but it makes a brittle joint.
