This project has step by step instructions along with pictures of each step so you can easily make your own handy lazy susan.
The Lazy Susan is a rotating tray that is usually circular and intended for use on a tabletop or countertop to aid in moving food on a table or counter.
Lazy Susans may also be corner cabinets on which shelves are mounted so that items may be retrieved by pushing on the shelves to turn them. This type is usually found in kitchens.
