Use a winding jig. A hand crank thing is OK if you
have an assistant. A better plan is to use a low
RPM/high torque motor to turn your form, while you
guide the wire on by hand. I based mine on an old ice
cream maker motor. You can pick up a new ice cream
maker at Wal Mart for $20, or a used one at a yard
sale or thrift store for $5. I made the jig frame of 2
x 4s, and the axle of a 1/2" wood dowel. I've wound a
number of secondaries on it, and have yet to break any
wire. After I'm done with the winding, I dunk a brush
in high gloss varnish and simply hold it against the
rotating coil. I let it turn until the varnish is
tacky, yielding a drip-free, glassy smooth finish.
Have a gander if you wish at:
