Not that I have the front trimmed down a little, I'm going to start getting ready to drill my main connector hole. I like to make a small hole first. This helps me make a guide for when I need the larger drill bit. If you don't want to make a guide hole, that is okay, but I tend to find I ruin more pieces when I don't make a guide. I use a pen drill to make the hole. A pen drill is basically a pencil sized drill that you can use for craft projects.
