Empennage

Jan 6, 2016  (catching up in new builder's log)

Vertical Stab (5 hrs)

Sec 6-4  Step 4 & 5.   Dimpled #40 holes in flanges of skeleton (ribs and spars).   Used Main Squeeze tool.   Set up drill press to use Micro Stop CS tool for #30 holes on Rear Spar doubler.   No pictures...but worked great.

Really careful to understand front and rear faces for dimple directions on Rear Spar (so will be flush facing forward !)

Prepped parts for priming by final scuffing, then clean thoroughly with Acetone.  Using good respirator - can't even smell the acetone or primer.
