Rudder Riveting and Trailing Edge Prep

October 27th, 28th and November 4th, 7th, 8th 2018, 18h

Riveted the horn brace. It was a bit tricky to get to some of the rivets.  The pneumatic riveting gun end up slightly damaging the the horn brace circle.  I fixed it by straighten it and sending it.

Installed the counter wait.

Riveted the counter balance skin and associated parts. The back riveting gun moved while riveting one of the rivets, bending the skin a little.  I checked with van and they said it is ok to proceed and that I can try fixing it with mallet.  The mallet fix did not work, but the bend is not that bad, so I decided to proceed with the current state.

Riveted the skeleton to the skin.  Some of the back rivets to attach the counter balance skin to the skin were tricky to reach, but by the end we were able to get all of them.  When getting toward the trailing edge, the pneumatic riveting gun, nor the backing bar could fit, so I had to convert those to pop rivets.

Fitted the bearings.  One of the bearing did not go all the way.  I checked with Vans and it is expected that this bearing would not go all the way.  As long as I see a couple threads outside the platenut, they said that it is good.  I checked that I have a couple threads.

Did some prep work for the trailing edge.  We primed the skin; however, after checking with Vans we found out that we should not have any primer on the skin around the trailing edge, or on the trailing edge.  So, we had to remove the primer, which was time consuming.  Then we buffed the area.

To get a straight trailing edge, I got an aluminum angle, matched drilled the holes in the trailing edge to the angle, deburred them and clecoed everything.  The trailing edge looks straight.  At the point of glueing the trailing edge, I realized that the proseal I both mentioned that it is for Granite, this did not seem right.  I called Vans, and it was not the correct proseal, good catch . I bought another proseal from Vans
