Suggestions for drilling 10mm hole in 1mm brass lighting canopy
Hi, I’m not a metalworker at all, just a reasonably handy person, and I find myself needing to put some 10mm holes in a concave / bowl-shaped brass light fixture canopy, and I’m nervous I’m going to dent it or shred it or something.
Is this something I could do myself? I have a drill, and I could get a special bit if needed. I assume I’d need some way to make a starter hole or nick the metal so the bit wouldn’t skate when starting out. Drill from outside in, or inside out?
Is there some good way to support it while drilling so I don’t flatten or dent it? It’s a round light fixture canopy so I’d be drilling into a curve, either from the outside (convex) or the inside (concave), if that makes sense.
