Either the gap is to large to get a bonding surface or their is a contaminate in the holes, such as mold release. Try flushing the holes with solvent of choice. To fill the gap try a viscus, gel, variant of CA glue. I use Locktite gel, available in most hardware stores. If all else fails, two part epoxy should do the trick. But the parts need to be clean for epoxy to bond as well.

I'm having some issues getting some brass barrels glued to resin turrets. I've attached them and used CA glue to get them permanently set, but strangely they're still quite loose. I even roughed up the brass so it would have some bite.
Should I opt for epoxy? or will the curing of it screw up the resin?
