Riveting rudder skeleton

5.0 hours

Priming rudder parts

I sanded, scrubbed, cleaned, dewaxed the rudder parts. I then primed with the rattle can. It was raining hard outside, but still warm and the primer didn't go on as well as previous. I don't know if it was the humidity or the can.

Riveting platenut and doubler

I started riveting the platenuts and doublers with the hand squeezer. The called out rivet was a tad long, but the next size down, was too short. This made the shop heads pretty fat, even though they are still a bit tall.

This is the manufactured head of the rivets in the last picture.

Rudder horn and lower rib

I started the riveting of the lower doubler, platenut, shim, rudder horn and rib. Not all the rivets could be done with the squeezer, so I got out the rivet gun for the rest of them

After the horn and related parts was on, I started the rudder horn brace. The plans call out a normal rivet on the bottom, with blind rivets optional. It would be quite tricky to get at the other side of those, so I went with the blind rivets.
