I have a marble coffee table (supported by 2 legs at either side) under which lies my AV equipment. At the moment it is stacked on each other. I wish to custom make a 2 shelf unit to slide under the table (i.e. the space between the legs). The bottom to house my amp, cd player + sky box, the top, the central speaker. I wish to add a single dampened hinged black/tinted glass door to the lower portion such that on tapping it opens upwards and out. It is the latter I am stuck with - anyone know where to get the latter cut or custom made?
