How to Build a Motorized Turntable

Save

A motorized turntable is a unique way for a store to feature a product to its customers or an interesting way to create a "lazier" Susan for your kitchen. The item can be assembled with a few basic parts costing a total of about $25. The potentiometer and the A/C gear reduction motor can be purchased at a local hobby store, while the remaining items are available at most hardware stores. Once assembled, a basic battery can be used to power the turntable.

Things You'll Need

  • Drill
  • Drill bits
  • Lazy Susan
  • Potentiometer
  • Battery
  • A/C gear reduction motor
  • Rubber bands
  • Nails
  • Hammer
  • Screws
  • Screwdriver
  • Wire
  • Plywood
  • Drill a small hole into the top of the plywood where you would like the turntable to be centered.

  • Bolt one of the legs of the motor to the hole in the board.

  • Stick a small piece of rubber or rubber bands on top of the shaft of the motor.

  • Strip the rubber off each end of two pieces of wire. Attach one wire to each of the positive and negative terminals of the motor.

  • Connect the throttle control potentiometer to the motor by attaching the negative wire to one of the end terminals. Connect the power source by attaching a wire from the negative terminal on the battery to the middle terminal of the potentiometer.

  • Touch the positive wire from the motor to the positive terminal on the batter to test out whether or not the shaft of the DC motor spins. Turn the knob on the potentiometer to confirm the speed is adjusted.

  • Wrap a rubber band around the body of the motor. Partially hammer a nail into the plywood a few inches from where the motor is mounted. Wrap the rubber band around the nail to create a "tensioner" for the motor.

  • Place the lazy Susan table next to the rubber mount on the motor's shaft. As you connect the positive terminal to the battery, the shaft will spin the lazy Susan table.
