TOOL REST POSITION

Mount the tool rest in place about 1/8” away from

the work and 1/8” above the work centerline (Fig. 32.)

This position may be varied to suit the work and the

operator. Place a guide mark on the tool rest shank as

an aid to quick and accurate resetting.

MOUNTING THE WORK

Mount the work by moving the tailstock to a position

about 1” or 1-1/2” from the end of the workpiece, and

locking it in this position. Advance the tailstock center

by turning the feed handle until the center cup makes

contact with the work. Do not support the work on the

center pin alone. Always have the rim of the center cup

imbedded at least 1/8” into the work. Continue to

advance the center while slowly rotating the work by

hand. After it becomes difficult to turn the work, slack

off on the feed about one-quarter turn and lock the tail-

stock spindle.

After marking each end, mark the true center with a

punch awl or dividers (Fig. 29). If the stock is hardwood,

the centers should be drilled to a depth of about 1/8”.

The spur or live center is then placed against one end of

the work and seated by striking with a mallet (Fig. 30). In

hardwood, make a starting seat for the spur center by

sawing on the diagonal lines, and drilling a small hole at

the intersection. After driving the center, hold the center

and the work together and fit both immediately to head-

stock spindle. If you are not using a ball bearing center,

the end of work at tailstock center should be oiled. Place

the lubricant on the wood either before or after it is put

on the lathe. Many turners use beeswax, tallow, or a

wax-and-oil mixture as a lubricant. A ball bearing center

is ideal because it eliminates lubricating. If the work is to

be removed from the lathe before completion, an index

mark should be made as a guide for re-centering (Fig.

31). A permanent indexer can be made by grinding off

one corner of one of the spurs.
