Brief Description: Countersink for #8 Screws - Top Wingwalk Area
Once the K1000 platenuts were riveted to the top wingwalk area of each wing I used the platenuts themselves to countersink for the #8 screws. I had a template that I used to verify the depth of each countersink.
Now all I need are my #8 dimple dies back to install the platenuts along the edge of the fuel tanks and on the bottom of each wing.
