Elevator Riveting

Time: 6 Hours

Today’s items for the hangar were to rivet all the stiffeners to the skins as well as the trim servo plate. The servo plate was made possible as my tool order from Avery tools arrived. I needed a #6 dimple die to dimple the plate where the #6 screws will hold the plate on the elevator. All these parts get back riveted.

20130605-223016.jpgThe next step will be to bend(flatten) the trailing edge of the left and right elevators. For this you need a brake and Vans describes how to make one. I used 2×6’s, one 5′ long and the other a little shorter. Then hinges are screwed to combine the two boards.

Half way done and they look great, it just takes a lot of torque! and need a good clamp. Today was a great day in the hangar, I’m going to have to order the wings soon since I’m running out of aluminum. 🙂
