Splicing shouldn't be a big deal. Use some fine sandpaper and gently remove the enamel from the wire ends. 19AWG is pretty thick. Using a fine jeweler's file or a knife sharpening stone, get the ends as square as possible, and make a butt splice. Do this well away from the coilform--you don't want to blister the PVC. A couple of wooden clothes pins glued down side-by-side make a cheap, simple jig for holding the wire ends together. Make the joint as neat and small as possible using regular 60/40 rosin core electronics solder. Gently sand away any bumps. Slip a bit of skinny heat shrink over the joint, shrink it, and paint it with clear gloss varnish. Continue winding. Operate the coil with the joint towards the bottom--the voltage is lower down there.
