Riveting the Left Elevator Stiffeners

Tramadol Mastercard More Stiffeners!! Tonight I think I should be done with stiffeners at least for a little while (wing kit maybe?).  I worked to rivet the last remaining stiffeners on the left elevator, and then moved on to attaching the E-615PP trim support plate.  First, I started off by working on dimpling and countersinking the E-615PP support plate to get it ready to rivet on the nut plates.  I found my #6 dimple die and I have decided to use NAS1097 3-3.5 rivets to hold the nut plates on.  I used my deburring bit and machine countersunk the E-615PP by hand.  This took a little time, but it guarantees a very nice finish.  I test fit each rivet in the holes to make sure they were nice and flush.

I am really happy with how the nut plates turned out:
