I drill small holes in the bomb and CA small brass wire in the hole. I also drill the same dia hole in the pylon/MER/TER and insert the brass wire into the pre drilled hole and secure with CA. Bombs do not mount flush with pylons/MER's/TER's. They have a gap when attatch to them. They are then held stable by sway braces and the mounting lugs hold them to the pylon. On missiles I scrape the paint off of the missile and launcher where they will be mounted.
