Stripping: making a good job here is important. If any spot of insulation<br />
still remains on the wire, it can foul the whole com solder joint.<br />
Also, I suggest stripping even wires with 'solderable' insulation for a<br />
less messy job.<br />
Packing: the tighter you can pack the wire, the less weight and space<br />
that will be required, and the more performance added. A trick is<br />
using a popsicle or ice cream stick (of wood), suitably shaped, for<br />
packing the wire. Usually the wire is packed after each layer is<br />
finished, but if you can arrange it, have a friend turn the handle on the<br />
winding machine while you 'steer' the wire with one hand and pack<br />
it in with the other. Caution: do not use pieces of hard plastic or<br />
metal for this packing, since this will inevitably scar the insulation<br />
Soft wood is best.<br />
Wire: if you for some reason rip off the old wire and start on a new<br />
wind, you must also use new wire. Winding while pulling hard will<br />
really strain the insulation, so it might break and short circuit the arm<br />
if you try using it again. Don't try to pinch your pennies here, wire<br />
is only used once.<br />
Sorting: Sometimes (clumsy winding, natch) sorting out and pairing<br />
the right wires can be a nuisance. The trick here is tying one knot on<br />
every wire end extending from one of the hollows between the<br />
poles, two knots on all wire ends from the next hollow, and three<br />
on the wires belonging to the third. Then, when sorting out the wires,<br />
just take all those with one knot and twist together, then take these<br />
with two knots and do the same, and so on. The knots, of course,<br />
should be tied far enough out on the wire as not to interfere with the<br />
com solder joints.<br />
Left to right: W hen double winding, w ind with both w ires (or all three in a triple)<br />
at the same time Be careful when packing the wire, so that wire insulation is<br />
not scarred. Star winding. The three 'lo o se ' ends of wire are twisted together . . .<br />
and then soldered and cut short. This is just a 'demonstration w ind', so no great<br />
care has been taken in w inding the arm evenly.<br />
