Got the counterweight ready for installation

I had heard too many homemade remedies for making these large dimples on other builders websites, so I decided to order a #10 drill bit and a set of #10 dimple dies to final drill the holes for the counterweight and the R-912 rib. I used my deburring tool to making the countersink hole in the lead counterweight. I started to put this thing together, but wondered how you would rivet the skin on with the lead weight in the way. So I postponed attaching the weight to the rib. About 5 lines down, the instructions call for attaching the counterweight after riveting on the counterbalance skin. I need to remember to read the whole section before starting anything.
