Pic. 1 shows the tools I used. I fabricated the "dog bone" (second from the left) from wooden dowel. Note the fish-mouths at each end. The dog bone is about 1 ' longer than the fish-mouthed tube that is placed in the thickest part of the airfoil. see pg 2-49. The forceps provided a longer reach into tight areas.
