The Carter Perfect Sphere™ Tool allows you to turn spheres from 1" to 14" diameter depending on your lathe capacity. This system can be used on lathes ranging from 10" to 25" diameter capacity.
The Perfect Sphere™ Tool utilizes a fixed pivot point on which the cutter head pivots side-to-side in an arc motion to cut the sphere to shape. Prior to shaping the sphere using the Perfect Sphere Tool, it’s necessary that the blank be roughed turned between centers to a sphere shape fairly close to the desired final size. For chucking the turned sphere to remove nubs leftover from shaping, we highly recommend the Carter M-Chuck Drive Center system.
The Perfect Sphere Tool system is supplied with an adjustable mounting base designed to fit most lathe beds, a Riser Stud that’s specific to your lathe capacity and a 6mm (#1) carbide cutter. If you’re not sure what your lathe capacity is, simply measure from the center of the lathe spindle to the top of the bed ways and multiply the distance by 2.
Example: If the distance from center of spindle to bed way is 8", your lathe capacity is 16". A 16" Riser Stud is the size you need to order.
