We are considering doing lazy susan cabs as two boxes, the large one edgejoined to the smaller at top, deck, and back, using pocket screws. Joining would be done on site.
This, for ELL-shaped susans outfitted with piehinged doors.
There are production advantages to doing them this way, and there might be some field advantages as well.
We build only frameless. An image is shown here of a 36×36 susan corner, showing the arrangement.
