how to make a bowling ball spinner

A bowling ball spinner is a device used to clean and polish bowling balls, helping to maintain their surface and performance. Building a homemade bowling ball spinner requires some DIY skills and tools. Here’s a basic guide on how to make one:

Materials You’ll Need:

  1. Electric Motor: You’ll need an electric motor with a variable speed controller. The motor should be able to rotate a bowling ball at different speeds.
  2. Plywood or MDF Board: A sturdy piece of plywood or medium-density fiberboard (MDF) for the base and support structure.
  3. Aluminum or PVC Pipe: A piece of aluminum or PVC pipe to serve as the ball holder or cradle.
  4. Bearing: A bearing or set of bearings to allow the pipe to rotate smoothly.
  5. Mounting Hardware: Bolts, nuts, and washers to secure the motor, pipe, and bearings to the base.
  6. Variable Speed Controller: A variable speed controller to adjust the rotation speed of the motor.
  7. Power Cord and Plug: A power cord with a plug to connect the motor to an electrical outlet.
  8. Safety Gear: Safety glasses, gloves, and ear protection for working with power tools.
  9. Power Tools: Electric drill, saw, screwdriver, and wrench.
  10. Measuring Tape, Pencil, and Ruler: For marking and measuring.


  1. Design the Base:
    • Begin by designing the base of your bowling ball spinner. The base should be large enough to provide stability and support for the motor, pipe, and bearing assembly. Measure and mark the dimensions on your plywood or MDF board.
  2. Cut the Base:
    • Using a saw, cut the base according to your marked dimensions. Ensure that the base is square and even.
  3. Attach the Motor:
    • Position the electric motor on the base and mark the locations for the mounting holes. Drill holes for the mounting bolts, and secure the motor in place using nuts and washers.
  4. Prepare the Pipe Holder:
    • Cut the aluminum or PVC pipe to the desired length to serve as the ball holder or cradle. It should be long enough to accommodate a bowling ball.
  5. Mount the Bearings:
    • Attach the bearings to the base and the pipe holder. The bearings should allow the pipe to rotate smoothly. Secure them in place with bolts and nuts.
  6. Connect the Pipe and Motor:
    • Attach the pipe to the motor’s shaft. Depending on the motor and pipe design, you may need a coupling or adapter. Ensure that the pipe is securely connected to the motor.
  7. Install the Variable Speed Controller:
    • Connect the variable speed controller to the motor according to the manufacturer’s instructions. This controller will allow you to adjust the rotation speed.
  8. Wire the Motor:
    • Wire the motor to the power cord and plug. Ensure that all electrical connections are secure and follow safety guidelines for wiring.
  9. Test the Spinner:
    • Plug in the spinner and test it by rotating a bowling ball at various speeds. Make any necessary adjustments to the speed controller or connections.
  10. Safety Precautions:
    • Always use the spinner in a well-ventilated area, wear safety gear, and follow safety precautions while operating power tools.
  11. Maintenance:
    • Periodically check and maintain the spinner to ensure that all components are secure and functioning properly.

Building a bowling ball spinner is a DIY project that requires some technical skills and knowledge of electrical components. If you’re not comfortable working with electricity or power tools, consider seeking assistance from someone experienced in DIY projects or bowling ball maintenance. Additionally, be sure to follow all safety guidelines to prevent accidents while using the spinner.
