After marking each end, mark the true center with a punch awl or dividers (Fig. 13). 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.
14). 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 bear-
ing 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 lubri-
cating. 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. 15). A permanent indexer can be made by grinding
off one corner of one of the spurs.

TOOL REST POSITION
Mount the tool rest in place about 1/8” away from the work and 1/8” above the work center-
line (Fig. 16.) 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.

ROUGHING A CYLINDER
The large gouge is used in the first turning operation by smoothing the sharp corners of the
work. Run the lathe at low speed and hold the gouge in the manner shown in Fig. 17 The cut
starts about 2 inches from the tailstock end and continues from this point to the end of the
tailstock. Make the second pass beginning about 2” or 3” to the left of the first cut. Advance
again toward the tailstock, and merge with the previous cut. Toward the end of the live cen-
ter, roll the gouge in the opposite direction (Fig. 18) to carry the final cut off the live center
end of the work. The roughing cut should not be carried out with one continuous movement,
because this would tear long slivers from the corners of the work. Neither should the cut be
started directly at the end of the stock for the same reason. The cut can be safely carried
