Fuselage, MID Lower Structure (Part 22)

Now that the Ailerons are finished, I switched back to the MID Fuselage Lower Structure.  Not a very long work session, but I did prep several parts.  These four parts started their life at Van’s known as F-01495AB Step Attach Rib Doubler.  After being separated, the two bigger pieces became the F-01495A’s and the two smaller pieces became the F-01496B’s.  All four pieces had their edges cleaned and holes deburred.

Here are the F-01495-L & -R Step Attach Ribs.  These came as two pieces and didn’t have to be separated.  All the edges were cleaned and holes deburred.  Additionally, the #40 holes in the upper (nutplate locations) and lower flanges were dimpled.

After being prepared, all six pieces were treated with Alumiprep and Alodine and hung up to dry.  Tomorrow, I will Akzo prime the parts and rivet them together.
