Two end pieces Of suitable size are
made from this board, and a quarter
men mole Is bored In the center Of
each. One end piece rs screwed to
each end Of the core, its center hole
coinciding with that In the core. The
spool thus formed Is slipped onto a
quarter-inch rod which has one end
threaded for several inches and the
other bent In the form of a crank. A
tap Is screwed up tightly to each end
OF the spool, and the whole Is mount
ed as shown in Fig. 2. The bearings
are simply wooden uprights with hole
Tor the axle. If all work has been
done with reasonable accuracy the |
spool should show no tendency TO
wobble when the crank Is turned.
Ihe first step before winding the
coll Is to be sure that 1t will slip off
the core readily when 1t Is finished.
Wind on the core a single layer of
small hard-twisted cord. This laver
must be wound perfectly smooth. and
the ends should be brought ont
through small holes in the end pieces
