Image 1) The back edge of the lower wing skin needed trimming to clear the hinge. I left it a little long so I could do this. Took off about 2mm where the hinge is and blended the rest to the outer end which was OK already.
Image 2) Got the 7' long hinge right from Zenith. Trimmed it to length and safety wired the lubricated pin.
Image 3) Clecoed entire back rear channel to black. That edge is rivet ready after deburr and prime.
