We have a custom made TV unit and we want to add MDF doors to the front. We ideally want to use concealed hinges, but the thickness of the cabinet frame is irregular -- double the thickness of a regular cabinet frame (for e.g., the frames used by Ikea). So the hinges would have to be inset on the back of door more than normal, to ensure that the door covers right to the edge of the cabinet frame. Trouble is, I suspect this would mean that the door wouldn't be able to open properly.
If this makes sense to anyone, any ideas?!
