Turning Cylinders

Stock for cylinders should be mounted on the screw cen-

ter or a small faceplate. The tailstock can be brought up to

support the work while the circumference is being turned

and finished. Afterwards, the tailstock is backed off and

the outer end of the cylinder is recessed, using methods

already described for making deep recesses.

After making a recess at least 1/2 of the way through the

workpiece, and finishing this on the inside, remove the

workpiece from the lathe. Now mount a short length of

softwood stock on the screw center and turn this down to

form a dowel that will be a tight press (not driving) fit inside

the recessed end of the cylinder. Mount the cylinder on

this wooden chuck, and recess the unworked end deep

enough to form a perfect hole through the entire cylinder.

Rechucking

Rechucking is the general term used to describe any ad-

ditional work mounting that is necessary to complete a

turning project. The method of working cylinders, and the

use of a plug chuck as already described, are typical ex-

amples. Another good example is the rechucking of a

bowl.

The work is first mounted on a wood backing block se-

cured to the large faceplate, and is turned in the usual

manner all except the back side (which is against the

mounting block). It is then removed from the mounting

block. An auxiliary chuck of softwood is now made in the

same manner that the cylinder chuck is made. This chuck

must have a turned recess properly sized to accommo-

date the rim of the bowl in a tight press fit. When the bowl

is mounted in this chuck, the bottom can be cleaned off

and slightly recessed to complete the desired contours.

Turning A Ring

One method of turning a ring requires a spindle chuck.

The work stock is first mounted to a backing block held by

the large faceplate, and is turned to shape on the outer

side. The inside diameter of the ring is also shaped, all the

way through to the backing block. The work is then re-

moved from the backing block. A spindle chuck is now

prepared so that it will be a tight press fit inside the ring,

and the ring is reversed and mounted on this chuck. Thus

mounted, the remaining contours can be turned to shape.

Another method of turning a ring makes use of a recessed

chuck. The work stock is mounted on a screw center and

one half of the ring is formed; but the ring is not cut away

from its center. The stock is then removed, and a re-

cessed chuck - mounted on the large faceplate - is pre-

pared to receive the ring in a tight press fit. After being

chucked, the remaining face of the ring can be turned to

the proper contour, thus cutting away the center portion.

In work of this type take constant measurements - or bet-

ter still, use a template - to guard against over or under

cutting.
