How to Make a Spinning Structure for Cakes

Clamp a 1/4-inch tempered hardboard plank to the edge of a workbench.

Cut the hardboard plank with a jigsaw to the appropriate length. The length of the hardboard should be the diameter of the Lazy Susan plus 1 inch. If the diameter of the Lazy Susan is 16 inches, the hardboard needs to be cut to a length of 17 inches. Use a measuring tape and a pencil to mark the hardboard before you cut.

Draw a straight line 1 inch in from the edge of the hardboard. Use a squaring tool to keep the line straight.

Cut along the line with a jigsaw until you are about ¾ of the way through the hardboard. Stop and remove the jigsaw.

Attach a piece of double-sided carpet tape to the bottom of the jigsaw plate.

Insert the blade of the jigsaw into the groove cut into the hardboard until the blade presses against the edge. Push the jigsaw down onto the hardboard to secure it with the double-sided tape.

Set the hardboard on top of one of the plywood squares so the edge of the jigsaw presses against the edge of the plywood. Hammer a nail into the dead center of the plywood sheet, through the hardboard. Don’t drive the nail all the way in, only far enough so the nail sticks.

Turn on the jigsaw and cut a circle out of the plywood sheet. The nail serves as a pivot point, so all you have to do is swing the jigsaw around the plywood on the hardboard template to create a circle. Remove the nail when finished. This circle is the table top of the Lazy Susan.

Repeat the process of cutting a circle out of the second piece of plywood. The second circle should be smaller than the first. This circle is the base of the Lazy Susan.

Wrap the edges of the plywood circles in wood edge banding. Rub an iron on top of the wood edge banding to melt the adhesive and glue it into place. Let the adhesive dry for 10 to 15 minutes before continuing.

Lay the base on a workbench.

Set a rotating disc bearing on the center of the base.

Attach the rotating disc bearing to the base with 1/4-inch pan head screws equipped with a 1/4-inch washer. Hand tighten the screws with a Phillips-head screwdriver.

Rotate the bearing 45 degrees. It doesn’t matter which way. Mark the locations of the mounting holes with a pencil.

Drill a hole into each of the marks with a power drill equipped with a 1/2-inch drill bit.

Lay the table top on the workbench.

Align the mounting holes on the rotating disc bearing with the drilled holes in the base. Flip the base over and set it on top of the table top.

Attach the rotating disc bearing to the table top with 1/4-inch pan head screws equipped with a 1/4-inch washer. Hand tighten the screws with a Phillips head screwdriver.

Apply 4 self-adhesive plastic feet to the bottom of the base. Arrange the plastic feet along the edges of the circle, one facing each direction -- north, south, east, west.

Cut a circle out of parchment paper the same size as the Lazy Susan. Place the parchment paper on top of the Lazy Susan to provide a barrier between the wood and the cake.
