RV-8 Only:

Dimple-countersink the #19 screw holes in the F-820-L-1 & -R-1 Fwd Side Skins for #8 screws.

Apply a slight roll to some edges of the fuselage skins before they are dimpled, to provide a flush fit to the un-
derlying skin (refer to LAP JOINTS in section 5 of the construction manual). Roll the aft edge of the F-820-L-1
& -R-1 (RV-8) or F-891-L-1 & -R-1 (RV-8A) Fwd Side Skins. Roll the aft edge of the left and right F-823-1 Mid

rivets (Refer to rivet callout details, DWG 74 or 74A).

CAUTION: The #30 holes at the fwd end of the F-842-1

Aft Bottom Skin Fwd for an RV-8A should not be dimpled on the left side because of the step installa-
tion (See “Detail C”, DWG 71).

Make notches in the F-887-L-1 & -R-1 Upper Longerons for the F-811C-1 Horizontal Stab Attach Bars as shown
in “Detail A”, DWG 66. Use the pen lines previously located by the notches in the F-819-1 Aft Deck, as the ref-
erence for locating the notches in the upper longerons.
