I used the C-Frame Dimpler to dimple both sides of the right elevator skin on all stiffener to skin holes. My daughter Haley pulled the skin back to allow for the proper clearance. We did not like the effect we were getting by trying to bend the skin back far enough to use the C-Frame Dimpler on the spar to skin holes. Instead I decided to use the pop rivet dimpler on all spar to skin holes that could not be reached with the pnuematic squeezer and 3" yoke.
All of the upper skin holes were drilled and dimpled to #40. The bottom skin to spar holes were drilled and dimpled to #40 wherever the squeezer could reach. The rest were drilled and dimpled to #30 for blind rivets. All #30 dimples were formed with the pop-rivet dimple die.
