Be sure to put the solder joint near the bottom of the coil, because the
voltage gets higher the farther up the coil. This will help keep down corona
losses. OR, since you have 2 identical rolls of wire, you coild put the splice
right in the middle of your coil and make a bipolar coil by mounting the
primary in the middle of the secondary and have the secondary go horizontally.

Yer in luck I tell ya.... :) You can just take a jewelers file, and file
the wire to a sloping point. file on one side of the wire only, and dont
remove the insulation on the other side. File it flat but sloping at
an angle to create a long wedge shape maybe 1/2" long. Then file
the other end the same way. Fit the two ends together with the 
filed portions touching, and you'll see it fits smooth with no bump.
Then fire up your soldering iron, and tin both sections. The solder
won't stick to the other side, where there's insulation. Thus,
the solder will stick only to the filed slope, which is what you want.
After both ends are tinned thinnly, overlap the ends, and heat the
joint with the iron, so it solders together, and you'll have a perfect
joint.
