On one of my arcade machines, I'm going to be installing a card reader. Now, I want to cut a smallish sized (about 4 inches by 2 inches) into the front bottom of the arcade cab. I will be cutting the hole from the middle of a thick board, essentially. What tool would I need to do this to make sure it's clean, so when I put the card reader in, it will look like it belongs there instead of some idiot hacking away at it?
edit: I think I found it. Use a dremel. It just so happens, I have a dremel set.... hope it's not too big for the job, don't want to wear out the wheel.
