With the left side completed, I started working on the right side. I still don't like this idea that the holes are already at proper size. There's too much pressure required to insert a rivet, so I'm drilling it out with a #30 drill.
Also not priming this part.They're easy and inexpensive to build, there's little liklihood that corrosion will be a problem, and even if it is,it's easy to just build a new part. That won't be the case on, say, the wings, but this seems like an area to save some weight.
