This is what I have done several times and it works fine.
Use some sand paper to remove the enamel coating on the very tip of
the wire. Over lap the wire about 1/8" and sold them
together. Make sure there is no sharp points on the wire or
solder. Use a very small file to file down the solder right down to
the surface of the wire if you can. Make a special effort to make
sure the solder connection is smooth. Paint the solder with
polyurethane varnish. Continue winding your secondary coil but
leave a tiny space on both sides of the solder splice. Move 1 turn
of the wire over about 1/16" from the close wound section. Leave a
tiny space on each side of the splice. It will make a goofy looking
place on your secondary but it will work fine.
