SPHERE
MACHINES

You can cut and polish your own spheres
with these machines

Two-cup machines will produce excellent spheres
and are generally the most used version.
A three-cup machine is sometimes preferred
for faster preliminary grinding,while the two-cup
produces a more perfectly round sphere.

"Three Head"
COOK SPHERE MACHINE

Manufactured by Jayhawk

This machine is designed for re-finishing bowling balls but can be modified to be used on rock type materials. You can add more resistance between the motors and the sphere by adding a heavy duty type of a spring to apply more pressure against the sphere.

You may also have to switch from using the pads that come with the machine to using cups made from PVC pipe or metal pipe modified to be placed on the shaft of the motors.

Also, may need to switch from using the pads to using powdered abrasives with a water drip system instead of the water recycling system that comes with the machine.

If you do use the recycling system that comes with the machine, you may have to install a filtering system.

    If used as is for bowling balls:
  • Finishes ball to uniform roundness every time!!
    (including balls with new or old plugs)
  • Solid stainless steel construction prevents rust and corrosion
  • Single set adjustment for hands-free operation
  • Slurry recirculation prevents build-up
  • Enclosed design eliminates splash over
  • Helps to remove lane oil from ball
  • Choose from 2 models:

  • #15-3910 - 10" Cabinet
    #15-3920 - 32" Cabinet
  • Full one year warranty
List Price is $3,995.00.
Our introductory price is $3,850.00.

Shipping weight is 240 pounds.
Please email to receive freight quote.


Comes fully assembled, adjusted and tested by professionals.
Included with your Cook Sphere Machine are the following items.
  • 6 - Contour Abrasion Blocks
  • 2 - 5" 320 grit packages of sandpaper (packages of 9)
  • 2 - 5" 400 grit packages of sandpaper (packages of 9)
  • 2 - 600 grit packages of sandpaper (packages of 9)
  • 3 - 5" Lambswool polishing pads
  • 1 - slurry recirculation pump
  • 1 - 5 gallon bucket
Adjustments " If there is unequal pressure on the motors the desired rotation will not be realized. To correct the pressure difference adjust the stainless steel carriage bolts found at the base of each motor mount. Be sure the lock nut is secure after making adjustments. A 9/16" wrench is required. " It is sometimes most effective to reverse the direction of rotation of one motor in order to achieve the random motion that does the best job. Warning: Be sure the machine is turned off before changing the reversing switch position!!
