(page 6-06) Gimme some skin....                

Vertical stab skeleton is complete, and the skin has been drilled and dimpled. The dimple die worked like a charm. Isham's tool kit even included the small diameter die needed to dimple the nut plates (not done yet). I had assumed I'd have to take the normal die to the bench grinder in order to do this procedure.

I did learn that the #40 holes should be dimpled before the #8 (larger) holes.  I started doing it the other way round and quickly saw that dimpling small after large distorted the large hole.  I recovered by re-dimpling the large holes.  Looks OK.  Dimpling all the nut plates required a lot of muscle on the squeezer.  I wish pneumatic squeezers weren't so expensive.
