I'm in the process of adding hardware to my bathroom vanity and as I have gone to drill the holes in the doors, I am hitting metal. It's hard to see what it is, but I believe it's a screw or a piece of metal on the joint where the wood comes together.
What do I need to do to get through it? OR can I just glue on the knobs and call it a day?![
