I use a 1/2 inch socket set extention that is 12 inches long, for the first wind...it is knurled on the bell end and that helps provide grip. For the outer coil I found a piece of electrical conduit that barely fit over the inside coil and it worked out to have the perfect side clearances when inserted is 2 inch copper.
