Turning Balls

Wooden balls of large size are first roughly turned be-

tween centers, using standard procedures. Smaller balls

can be mounted as faceplates on the small faceplate or

screw center. Lines drawn to indicate the center and ends

of the ball shape are helpful in plotting the curve. A tem-

plate should always be used for accurate visual observa-

tion of the work progress.

If the ball is mounted as a faceplate turning, almost the en-

tire surface can be turned before it becomes necessary to

rechuck it. Rechucking can be accomplished in a deep

cup chuck which will hold the finished portion of the ball in

a tight press fit. Another method of rechucking is to use a

shallow cup chuck which will not support the ball alone,

but must be used in conjunction with the tailstock. When

using the shallow chuck, a wood block is fitted to the tail-

stock so that the ball can revolve upon it. This block

should be lubricated with beeswax or grease. In using the

shallow chuck method, the ball is constantly shifted - nev-

er more than 1/8 turn - and always with a definite system.

Since turning between centers makes the work a perfect

sphere across the grain, the ball must be mounted in the

chuck so that the first scraping cuts will round it up in the

opposite direction.
