It depends on how you plan to use it. You might need to drill holes in one of them so you can access the screw holes attached to the other piece. I built a rotating drum tuning table with this; the platform is a 24" round board that I also picked up at my local Home Depot. But I didn't mount another board to the bottom; instead, I added rubber feet.

This is not the recommended application for these Lazy-Susan's as they are not meant to be stacked. The concern would be with getting them fastened to each other and to the marble slabs securely.
The bottom is the base. Use the holes to secure the base to whatever you are installing the Lazy-Susan to give it stability. Use the holes in the top (rotating part) to attach the board to the Lazy-Susan.
It might but I recommend a slightly larger version. Great idea a d your idea will work. Good luck!
I know this is a late answer but it’s a fun project! The weight should compress the base. Attaching the speakers to the bottom of the base, as described, will have the opposite effect on the Lazy-Susan. This can be mounted to the ceiling by extending the length of the base using 1” X 2” boards and attaching the blocks of wood to the ends of the extension boards and secure the speaker through the center of the Lazy-Susan. This method will compress the Lazy-Susan as designed. Plan the project out before you start so you know how you will secure the Lazy-Susan/speaker combo to the ceiling. Perhaps you could attach the risers to a “mounting frame” (4- 1” X 2” boards made into a frame) to install the Lazy-Susan to the ceiling. Don’t forget about the load bearing effects of the screws when planning how you will join the pieces.
Yes. As with anything, you’ll want to be very careful to mount it in the exact center of your cutting board
I think it would be easy to use to support a PC monitor. I would get two boards to affix the susan to and the monitor would be supported just fine considering the weight limit. It’s a very straight forward piece to swivel whatever you want.
NO. It is very small. I used mine for a sculpture on a stone slab about 1' x 1'
