The diagonal method, Fig. 29, consists of drawing lines
from corner to corner, with the intersection marking the
center of the work.
After marking each end, mark the true center with a
punch awl or dividers (Fig. 30). 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. 31). 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 headstock
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. 32). A permanent indexer can
be made by grinding off one corner of one of the spurs.
