Brief Description: Tip web assy./marked up rivet locations
I drilled the pilot holes in the spar cap for the tip web assembly (SNX-W10-04L). I also started marking out the various pilot holes on the entire spar to keep track of what kind/size of rivet goes where. I'm using a master rivet legend that uses different colors for different types/sizes of rivets. I mark the pilot holes with Sharpies that match the color code of the legend.
