Stick a washer over the hole using double sided tape. Chose the size to constrain the drill. I wasn't brave enough to use an electric drill, so I used a hand pin chuck over a couple of evenings. The metal isn't hard and after a hole is drilled, the residue should wind out. I used a triangle needle file for that. The wood is hard so it's usually OK.
