Thanks guys!
CA glue probably would not stand up to the shock and heat on a motor (especially heat). Not to mention CA works by chemically bonding with plastic/rubber, which probably won't work as well with metal, if at all. I was thinking about JBWeld too, but noticed that it tends to get softer with heat. I don't plan to overheat my motor, but better safe than sorry. From what I understand, Locktite works by turning into a plasticy substance and expands, while bonding somewhat to the metal, so I figured this would work better. And the screws are just to make sure. I may add a couple more screws if I can find some that are the right size.
It doesn't take much accuracy to drill the holes; just go slow and apply "back resistance" so you don't break through and hit the coils. In my case, I had nothing to lose since the motor was pretty much shot as it was.
