Spent the first part of this beautiful Americas birthday weekend clamping, match drilling the center and tip spar doublers, as well as deburring the holes. I also traced the the aileron push rod hole that had to be cut out. Not sure why this part isn't match holed and precut, but I assume it's part of what goes into the 51%. Either way, it was pretty simple and fun to really fabricate a piece. Between a step drill and the little sanding wheels chucked up in the dremel, it was a fairly quick job.
Due to the scuffing that happened when cutting out that hole, I decided to just scuff up the whole doubler and the corresponding section on the spar for priming. Pretty much at the same time I clecoed the fork and doubler to final reem them to #30. I also final reemed the skin attach holes to #40 since you won't be able to get to them once the fork is installed. They will get dimpled as well, next….
