I am beginning to hate the left elevator!!!  It isn't that hard, it just seems that I never get anywhere on getting this darn thing completed.

After fixing the stiffener problem I created last night, I continued on by riveting the plate nuts onto the trim servo stiffener plate.

One thing to mention here, is that plate nuts (K1100-06) will be attached to the inside of the trim servo reinforcement plate.  The rivets attaching the plate nuts to the reinforcement plate are required to be flush in order to later attach the trim cover plate.  There are basically two options you have in order to use the flush rivet (a.k.a. AN426AD3-3.5 in this example).  You can dimple the plate nut -OR- you can countersink the trim access reinforcement plate (E-615PP).  I chose to DIMPLE the plate nut.  No particular reason here, however, that required me to modify my dimple die in order to properly dimple the plate nut.  I just took the dimple die to the Scotch-Brite wheel on the bench grinder and removed material from the female die.  I only took the minimum necessary so that I could get the dimple die up next to the plate nut.  If you don't do this, the plate nut will "cock or tilt" when squeezed which can result in breaking off the pin on the male die and/or a crooked dimple.

Just another picture showing how much material I removed from the dimple die.  I am still able to use the dimple die in "regular" dimpling applications as the performance of the dimple die was unaffected by removing that edge.

I was able to get all these rivets with the pneumatic rivet squeezer and a 2.5" flange nose yoke.  Everything looks good so far...

Looks good from the inside too.

I also riveted the brackets for the electric trim servo to the trim cover plate.  If you look closely to the print (DWG 4, Electric Trim Assembly), it gives you the dimensions on where to mount these brackets from the edge of the cover plate.  Ensure you dry fit everything first to make sure that the trim cover plate will sit flush against the reinforcement plate.  Additionally, if you look closely to the right servo bracket, it overhung the trim cover plate cutout.  I used a rotary burr bit in the Dremel to radius the bracket to perfectly match the curvature of the trim cover plate.

Everything looks straight with my calibrated eye...

After I completed riveting the trim servo plates, I bent the elevator skin over in the make-shift brake.

Installed the elevator skeleton and final drilled all remaining holes.

Then it was back to deburring, dimpling, blahh-blahh-blahh.  Same ole repetitive stuff.

I decided not to prep and prime parts today.  By the time I got this far, it was borderline to late to a priming project.
