This is how I made insulators that has been in use for close to ten years:

/*T*/*/wo electric fence plastic "egg" insulators connected by 12 inch 
sections of fiberglass electric fence post.  A hole equal to the 
diameter of the fiberglass rod was drilled in one end of each egg 
insulator.  The rod was inserted and pined with a small brass nail.  
This produced a strong lightweight high voltage insulator that was 
tested to hold 200 pounds.
