Miles, When gluing two dissimilar materials such as brass and plastic ("I find gluing plastic to metal a problematic activity.") i have found two solutions that have served me well. Good old Walthers Goo which i apply to both surfaces and then heat (i use an old hair dryer) until it just bubbles; then join both surfaces. I have some joints that have held for over 20 years using this method. A more recent discovery (thanks to Gunrunner John) is a product called Loctite 380. It is a rubberized CA with a working time of about 90 seconds, sets in 1 hour, and fully cures in 24 hours. To save you some searching time, it is NOT distributed in the hardware, automotive, or mass merchandiser channels, but rather in the industrial supply channel. I get mine from a machine shop supply house. It's not inexpensive, but has recently become my "go to" adhesive.
