This last one was already cut, but I would use just 3" or 4" wheels, metal cutting. The thin ones. You might damage a wheel, but one should do. I've noticed the longer length die grinders give you more control but any would work, harbor freight has cheap ones, like $30. I'd mark it with tape and take it slow. Once you get the wheel cutting, it wants to stay straight which is nice.
I made my own doors out of angle, welded it together. Made it so the glass would drop in and have a backing. Used plate glass from a local company that was custom cut. The door was a little heavy, I should have tried to keep it a little lighter. Think I used 1/4" plate. Used some magnets to keep the door closed. If I had to do it over, I would have made the hinges hidden behind the back.
