The door on left is a solid 3x1 tube door with a slot on back side that a piece of glass will slide into. The overlay on right is a wood core door I covered with 18 gauge sheet metal bent around by bending brake and welded up. Then its routered out on back to let the mesh sandwich between fridge door and overlay panel. I'm not showing the backs because I Dont want to give my secrets away. The point was to make them look the same but the overlay door had a weight limit of 10 pounds. I came in about 7 lbs. This was a lot of fun. Will shoe finished piece soon.
