[Elecraft] Toroid Winding Question

[Clark Macaulay]

Perhaps this question has been raised before, but I haven't been able to find it in the archives nor in the manual.  
   
  I've built a K1 (words fine) and am now building a K2. Yesterday, while finishing one of the first toroids in kit, I noticed one of the turns had crossed over the previous one, so I began to unwind it. Then I noticed that the wire had the enamel nicked in several places and chose to replace it. 
   
  In thiking over what might have happened, wondered if I may have been pulling the winding too tight. Currently, I'm "pushing" the wire through the center of the core rather than "pulling" it so as to keep it away from the core to minimize scratching it. Obviously, though, it's not possible to know if the winding has been scratching in making the bend around inside.
   
  So, my question is, to quote Shakespear, is my concern "much ado about nothing"? Am I winding them too tight (I noticed there are LONG leads after winding that could indicate the turns are too tight)?
