I’m countersinking and dimpling all the parts of the forward fuselage as needed. I see in the instructions to dimple the skins that rivet to the fore and aft flanges of the center section spar. I can’t find the proper prep for the spar itself. I suspect it is to countersink as was done on the wing. Is that correct?
---> found the answer going back through the prior instructions:
"Machine countersink for dimples, the #30 holes in the F-822-1 (RV-8) or F-890-1 (RV-8A) Fwd Floor Panel that
are common with holes in the fwd and aft bottom flanges of the Center Section Assembly. These holes will accept
dimples in the common holes in the F-826-1 Left Center Bottom Skin and F-827-1 Right Center Bottom
Skin."
