Lazy Susans can maximize space in your cabinet. They allow you to put all your spices and materials on a rotating platform, allowing you to see your entire selection of spices and goods. Rather than have to move ingredients around, a Lazy Susan will simply let you display your ingredients and rotate them around. Making one is a fairly simple craft, especially if just starting in woodworking.
Use the measuring tape to measure the depth and width of your cabinet. Take the smaller of the two measurements and subtract two inches. This will be the diameter of your top layer.
Draw a circle with the diameter you calculated onto your plywood. Draw a second circle with a diameter about 3 inches smaller than the first.
Cut out the circles using your jigsaw.
Take your Lazy Susan bearing, and center it on the larger circle. Mark the bearing's holes with a pencil.
Rotate the Lazy Susan bearing just a bit, and mark the four holes of the second part of the bearing onto the smaller wood circle. Cut out four one-inch circles around each of the marks. This will allow you to screw in the bearing later.
Sand down your circles, prime and paint them.
Screw one part of the bearing down to the larger circle.
Place the smaller circle centered over the two bearings, and screw on the second part of the bearing using the holes you created.
Flip over your Lazy Susan, and use it.
