rovided;
also metal shears and a small square; an awl and several sizes of
gimlets; a screwdriver; pair of pliers and wire cutters.
From the foregoing it will be seen that the cost of tools is not a very
expensive item.
This entire outfit, not including the anvil and vise, may be purchased
new for about $20.00, so we have not been extravagant.
MAGNET-WINDING REEL.--Some little preparation must be made, so we may be
enabled to handle our work by the construction of mechanical aids.
[Illustration: _Fig. 4. Journal Block._]
First of these is the magnet-winding reel, a plan view of which is shown
in Fig. 2. This, for our present work, will be made wholly of wood.
Select a plank 1-1/2 inches thick and 8 inches wide, and from this cut
off two pieces (A), each 7 inches long, and then trim off the corners
(B, B), as shown in Fig. 4. To serve as the mandrel (C, Fig. 2), select
a piece of broomstick 9 inches long. Bore a hole (D) in each block (A) a
half inch below the upper margin of the block, this hole being of such
diameter that the broomstick mandrel will fit and easily turn therein.
Place a crank (E), 5 inches long, on the outer end of the mandrel, as in
Fig. 3. Then mount one block on the end of the bench and the other block
3 inches away. Affix them to the bench by nails or screws, preferably
the latter.
On the inner end of the mandrel put a block (F) of hard wood. This is
done by boring a hole 1 inch deep in the center of the block, into which
the mandrel is driven. On the outer face of the block is a square hole
large enough to receive the head of a 3/8-inch bolt, and into the
depression thus formed a screw (G) is driven through the block and into
the end of the mandrel, so as to hold the block (F) and mandrel firmly
together. When these parts are properly put together, the inner side of
the block will rest and turn against the inner journal block (A).
The tailpiece is made of a 2" x 4" scantling (H), 10 inches long, one
end of it being nailed to a transverse block (I) 2" x 2" x 4". The inner
face of this block has a depression in which is placed a V-shaped cup
(J), to receive the end of the magnet core (K) or bolt, which is to be
used for this purpose. The tailpiece (H) has a longitudinal slot (L) 5
inches long adapted to receive a 1/2-inch bolt (M), which passes down
through the bench, and is, therefore, adjustable, so it may be moved to
and from the journal bearing (A), thereby providing a place for
