Sec 8-6, Step 1: Completed grinding radii to forward corners of Nose Rib flanges. Just like done for Vert Stab. Fluted flanges of ALL ribs to insure all holes straight line on flanges. Certain ribs are easier to bend slightly the web between flange segments to align holes ( straightening out the web also).
Step 2: Two Nose Ribs have rear flanges opened 10 degrees each. And Two HS1004 Inspar Ribs have rear flange opened same 10 degrees, plus front flanges closed 12.4 degrees (with forward portion of web opened 2.5 degrees. Checked results against each other to confirm equal (mated end to end to check "zero" out each other).
Sec 8-7, Steps 1-3: Cleco'd Nose Ribs and Inspar Ribs to Front Spars (2 each w/ special 10 degree bends on end flanges). These are in middle to align with tail cone later.
Steps 4-5: Disassemble to deburr edges and holes (except few per instructions). Dimpled all #40 holes on all Nose, Inspar, and Inboard Inspar Ribs. Main Squeeze again used since can't use C-Frame. Carefully checked depth to insure flush w/ skin (used scrap alum piece same thickness as skin, since skin not yet dimpled).
Sec 8-8, Step 1: Start to prep 901 Skins. Removed inside & outside blue film. While some builders leave film on to protect during build, I decided to keep simpler and totally remove film - as I did previously for rudder. Marked holes NOT to be dimpled on each edge (this determined which is right vs left skin...so critical !) Thus clearly labeled skins as Top vs Bottom, and Left vs Right.
