Page 7-10, Step 5: Finished skins to spar riveting (both sides from middle to top; and middle to bottom). Lots of 426 3-3 rivets set by Cleaveland Aircraft Tools Main Squeeze. Sure works great !
Started page 7-11, Step 1: Rivet Counterbalance Rib to skins. Installed Counterbalance lead weight. Needed longer extension for 1/4" drive to reach via my smaller torque wrench in relatively tight space. Got one at Menards for $2.50 today, so quickly completed at 20-25 in-lbs. Good these are locknuts.

Step 2: Completed Top Rib riveting. Pleased with results.
Almost done...except for TE rivets and roll leading edge.
