Need Help with a Hardware Bracket set-up...

Hi!
I own an Oracle Delphi Mark V Turntable, with a (Black African Granite base). It sits on a blue/gray vein~white marble shelf at my house. I also have a full-sized clear acrylic dust cover, which fits over top of all this turntable & base. The problem I'm having is, that there's also another Permanent self,right above this turntable shelf. It too, is solid 16" wide X 6 foot longX 1-inch thick marble.

What I'm looking for is, some kinda shelf brackets that can attach & slide out from the shelf that now suspends the "Heavy" Oracle turntable,so that I can pull out the Oracle away from underneath the overhead shelf& out & away from underneath. Then when I'm "NOT" using the Oracle on this shelf, I can slide it back into it's normal shelf position.

Question: can someone hook me up with something? As far as brackets, etc.. I can get another piece of white marble to attach to this bracket to fit under my Oracle Delphi & make this work (Custom Made)
Let Me know what you can come up with ??
