Can someone tell me how to attach a baton to a wall for affixing a curtain rail? I'm wondering about two options that I can see so far, the first is to glue the rail on, if so what type of glue would be best? Or secondly drill into the metal lintel, if so what type of drill bit would I need as I don't know if I have a drill bit suitable for metal? I'm personally in favour of option 1 as it seems like less hassle, but just not sure if its suitable. Hope you guys can help.
