Awesome, good luck with the bevel cuts.
There are a lot of ways to do control panels. Personally, I don't hinge mine. I leave openings on the bottom of my control panel box, then shut the top with control panel latches. To open up the control panel, I reach in through the coin door and pop the latches. You can use CP latches to mount the box itself as well. It is easy to install and leaves no there is no exposed hardware. The downside is that you can't leave your control panel open like a car hood.
I have heard good things about industrial velcro, too. I would never use it, but it is a cheap option that might be worth at least trying.
