For the base take piece of half

q of the legs Of the staple, glueing it as
ID wind it; be sure, however, that it does
10 stick to the iron-until you have paper

b it off the staple, and make another tube
A exactly the same way
Fake piece of 1s inch wood and saw out
sr circles, * inch in diameter, and in the
Rtre of each cut hole y inch. In two of
circles, with small brad-awl, drill hole
21r the outer edge, and also one near the
L, as in Fig. 2. Glue circle on to each
of the tubes. pushing the tubes trough
holes until their ends are flush with the

Ifter the glue has set, these spools are
be wound full of No. "a cotton-covered

wire through the hole in the head OF

then proceed to wind the wire evenly
to the spool, carefully watching it as you
Id, to see that it is not broken under the
Pering until the spool is full. taking care
\ the last layer does not come beyond the
DIS. Pass the end of the wire through
hole near the edge of the head. and cut it
leaving about four inches outside the

be manner, being very sure that 1t is wound
he same direction. If, during the winding,
should find break in the wire, scrape

Fake a piece of stiff wire about 1-l6 inch
