Robert,

I built my secondary like this because the wire I salvaged was not in long
enough sections for one continous winding.  When I got to the end of one
section, I didn't strip off any of the insulation but simply left the cut
end flush with the rest of the winding and tacked it in place with super
glue and accelerator.  Then I butted the end of the next piece to the end of
the previous, glued it in place, and continued winding.  When I finished
(there were three junctions) I applied a little flux and then a soldering
iron with a small blob of solder on it to the joint and let the solder wick
in.  I may have created a shorted turn or two, but I have not had any
problems with my secondary.

Hans
