Tonight I prepared the flap braces. First I trimmed the flanges…

Then I clecoed them to the spar, and clecoed on the skins and matchdrilled the braces.

After that I removed the braces and countersank them for the skin dimples. I used a piece of wood to cleco the braces onto, and to guide the countersink pilot.

Last I deburred the lightning holes, rivet holes and edges. Ready for primer!!
