A Lazy Susan turntable is usually a round, rotating tray that is placed on top of a dining room table to make it easier for everyone to reach condiments or dishes. A Lazy Susan can also be installed into hard-to-reach corner cabinets in your kitchen to make items easier to find. Lazy Susan turntables can be purchased at most kitchen and department stores, but it is also possible to make one yourself if you follow the right steps.
Draw two circles on two 3/4-inch birch plywood squares. One circle should be 15 inches in diameter, and the second should be 7 inches in diameter. Use a protractor or other measuring device to ensure the circles are exact.
Cut the circles out of the wood squares. Use a jig saw or circular saw. The larger circle will be the top of the Lazy Susan and the smaller one will be the base.
Place circles gently in a vice one at a time, and apply wood edge banding around the edge of the circles. Wood edge banding is a thin strip of solid wood with a layer of hot melt adhesive. Use a clothes iron to attach the wood edge banding around each circle. You may have to use quite a lot of pressure for it to adhere. Once you have made it all the way around, cut the banding on an angle to minimise the seam.
Place a bearing assembly in the centre of the small circle. Attach the bearing to the circle with pan head screws.
Rotate the unattached side of the bearing assembly about one-quarter turn, then place a mark on the wood through the hole. Drill a half-inch hole all the way through the small circle where you marked it.
Lay the big circle on a hard surface and centre the base with the bottom facing up, on top of the big circle.
Rotate the small circle until the hole you drilled lines up with one of the mounting holes on the bearing assembly. Insert a screw through the hole to attach the bearing plate to the underside of the large circle. Continue to rotate your base and insert screws until all four have been attached.
Purchase a tool from your hardware store to help find the centre of the circles if you have trouble.
