   Bob,

       I'd like to add one additional suggestion to Roger's post.  
Try
   to find a piece of aluminum tubing that will fit tightly inside the
   furling tube.  Cut a length of this tube approximately four inches
   long.  This section should be slid inside the furling tube and
extend
   at least two inches into each of the furling tube and the add on
   section.  Have the welder put a couple of "rosette" welds on either
   side of the joint to be welded.  Roger may think this is overkill
   but,  better to be safe than sorry.

   Todd
