Complete a mock assembly of your half-moon lazy Susan kits to see how each lazy Susan goes together. Ensure the lazy Susans will work for the cabinet measurements you obtained. Check the lazy Susans' dimensions to determine whether or not it is necessary to cut out the cabinet shelf so it does not interfere with a lazy Susan.
Set one lazy Susan kit's face bracket with bottom mount against a corner cabinet frame on the side where the door swings open. Drill in the accompanying screws for the kit's wall bracket and for the bottom mount. Add the shaft collar for the shelving pole. Read the parts manual that accompanies the kit to ensure you use the correct size screw for the part. Complete this procedure for each lazy Susan you wish to install.
Assemble the lazy Susan shelves to the frame assemblies, which hold shelving at a right angle to the pole assembly you will add later. If you use a slide assembly, then add a holding screw at the end of the slide runner, which is uncovered when you pull out a shelf. Add a lock washer and hex nut to tighten each screw into place securely.
Slide the shelf post through the circular collar of the shelf bracket of the bottom shelf, and place the pole onto the shaft bracket and bottom mount. Center the bottom shelf over the bottom mount, and then push and seat the pole into the shaft holder on the bottom mount to secure it in place. Add the mounting bracket for the top shelf, and screw it into place against the wood frame about half way up the pole. Slide the circular collar of the top shelf over the top of the pole, and seat it against the holding bracket. Add the pole cap to finish the project.
