Elevators, found another defect

I got a shipment from Avery Tools that included a handy little dimple die set that uses a finish nail and a pull riveter to make dimples in really tight places. I used it to dimple some of the holes in the really tight spots on the inboard and outboard ribs. It still takes a bit of doing to get this tool in place - the nail has to be able to make the angle to go through the hole. I ground down one nail to make it easier.

I finished deburring, dimpling, and countersinking the right elevator.

I started work on the right elevators. Before too long I discovered another mispunched hole, this time on a counterbalance skin:

The corresponding hole on the other side was off as well:

I sent an email to Joe at Van's to see if they'll replace this skin. The last time this happened I simply put the rudder on hold and moved on to the next assembly. Tomorrow I'll see if I can move on to the trim tab. If not I may be stuck until the replacement arrives.

Time spent: 1.5 hours (59.5 total)
