Cutting gaps in wood?
Alright, so I have this plank of wood, it's been sitting in my backyard for a long time, so I figured I'd do something with it. I cut a piece off and the dimensions are about 3.5" long, 2.75" wide, and 5/8" thick. I want to know (because I can't think of a way) if there's a way to cut a gap in the wood so I could put something inside with minimal cutting. It's really hard for me to explain, so you might need to check the pictures. I was thinking about using my Dremel, but I still don't know how that would work out. I have lots of wood to waste, so any ideas would help. Thanks!
