i just picked up an old frame with campy semi-horizontal dropouts. they have some set screws, that i'd like to retain, but i gotta have the frame refinished. how do i go about this? i'd fiddle with them, but i don't want to hurt them. also, what's the best way to mask them off for the powdercoater? i'll probably ask the guys at the metal finisher, but i wanna be armed with suggestions, in case he's stumped...
thanks
