Completed Step 7 for RH top and bottom Skins and Step 8, Countersink TE Wedges. These countersinks required a few clicks (thousandths) on microstop to allow dimples in Skins to fully seat on TE.

| 1st countersink on TE showing depth (used scrap piece prior to set depth). |

| Scrap alum sheet holds wedge level. Angle in back insures positioning. |
Step 1-3 @ Sect 9-10: Dimpled Left Inboard Shear Clip only (1 of 3)...glad I labeled these during disassembly. And dimpled Inboard Tip Ribs, and all Ribs.
I mounted Main Squeeze tool to workbench, as I'd seen in another builder's posting. It was MUCH easier to hold a part while positioning into hole and squeezing - vs clamping a part and holding the Squeezer. Don't recall the builder, but sure glad I discovered this arrangement !
Jumped to Sect 9-11, Steps 1-4: Additional #40 holes to dimple: LH & RH Root Ribs, Trim Access Reinforcement Doublers and Brace.
This required using #6 screw dimple dies in the #27 holes for the Nutplates. I used a K1100-06 Nutplate to confirm large dimple fit correctly.
Completed LH & RH Spars - lots of holes ! Also dimpled the #40 holes in all 7 K1100-06 Nutplates, from Sect 9-12, Step 2...working ahead a little.
