Thanks for all the info and the link.  I worked a little more with the super glue and was able to have more success but I really need to get some of the gap-filling type as I was just using some of the thin stuff that I had on hand.  I also found some old ABS glue I had left over from a plumbing project (the black goop) and that also sorta seemed to work, so a good ABS glue like Bondene should also do the trick, if I can find it locally or order it.
