The next step is match-drilling the counterweight skin and ribs to the lead counterweight itself. Vans recommends using a drill lubricant, which seemed to help when cutting through the lead. I also pilot-drilled the holes to #30 before final drilling them to #12.

The final result…the assembly looks good. Can’t do much more until I prime the skins and stiffeners.
