Riveted the roll bar with it clecoed to the fuselage. Was able to complete most, but not all the rivets in that position. Match drilled the bases as instructed. Removed the roll bar and completed the riveting. Also found the two additional holes to countersink that I was confused about yesterday.
Rigged up the roll bar to sawhorses to do the final painting before I reinstall it on the fuselage. Painting is much easier this way than by trying to do it when the part is on the fuselage. Began pulling parts for next several steps.
