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.
The coil that I use for experiments has four splices. I made it with wire taken from relays. All carefully soldered with 3 mm overlap, and with one wire over the other, radially, so there is no gap in the winding. With several layers of polyurethane over the windings, there is no problem at all
