Dan,

Find a short piece of copper tubing that will fit inside of the tubing that 
you are winding your primary with.  Mine was 3/8" tubing and I believe I 
used 1/4" inside for the splice.  Cut both ends square that are to be 
joined.  Clean with fine sand paper or scotch brite - inside and out.  Cut 
the smaller piece about 1/2" long so you will have insertion of about 1/4" 
into each piece to be joined.  Sand this piece clean also.  Coat this piece 
with flux.  Insert 1/4" into each piece to be joined, heat with propane 
torch, apply solder to the joint until it wicks inside, wipe off with a 
clean dry rag.  If you haven't done any copper pipe soldering before, maybe 
practice this first.  It provides a clean smooth joint that you can hardly 
tell is there.
