My Master bedroom of my house is an addition, when they built it they dug a rec room out from under it, so what I have is a 14' x 14' rec room with 4 cinder block walls, the door is a rudely punched hole through one of the walls, neatly capped with pine, just like the rest of the room.
I would like to make a cast iron door, sorta like jail door made of bars to place in this one opening to make the room into a big safe.
I have two questions that I hope you guys can help me with:
1) I can fasten the outer frame securely to the concrete floor, I can also secure the top to the footer of my house. The sides are where I have no ideas, behind the cedar it looks like someone made the doorway through the cinder blocks with a sledge hammer, leaving anywhere from 2 to 5 inches of jagged brick to try to secure something to, and ideas for a way to anchor the sides?
2) Locking the door, I could use a simple padlock but I would like to be a little more fancy, like a wheel that would control 2 to 4 rods that would slide into holes in the frame, like a safe.

I don't want the door to be solid, just reinforced bars. Any thoughts on the locking assembly and anchoring the sides?
