Today I drilled the access hole in the left aft side skin of the fuse. Then the access hole in the 419 deck plate. With that, I located and drilled out the rectangle area you see in image 1, for the elevator horns. Spent the rest of my time today locating, trimming, and drilling the canopy rails in place. I placed the roll cage in its spot, to ensure that I did not drill a rivet hole too close to it.
