Do you really have to have a bond between the two?
Yes, is better you bond them...so they act as one single structure....
We also noticed that they always brakes at the taped 4-40 holes for the retracts..... it seems that it apply some kind of stress over there.....Perhaps instead of tapping the holes for 4-40 thread....could be better to use a washer with nut.
PS.: after giving some thoughts.....definitely gluing both is mandatory or one will help to brake the other at the holes for the retracts.
