Front Wing Spar

January 5th, 2018, 2h

Worked on the tie down assembly:

  • Grinned the brackets to size, since we only needed to remove about amm.
  • Drilled matching hole with the main front spar.

We were not able to go ahead with the fabrication of the spacers wince we needed a blade for cutting metal for the bandsaw, so I ordered one to follow up on this work next time.

We started on the front wing spar, we worked on the plate nuts on the sides of the spar, for both wings:

  • counter sinking the side holes for the rivets
  • priming the holes
  • riveting the plate nuts
  • countersinking for the screws

Finished the Elevator

December 15th and 16th 2018, 10h

  • We pop riveted the remaining hard to reach rivets
  • we rolled the leading edge of both the left and right elevator
  • We riveted the leading edge of both the left and right elevator. It was a bit tricky to get the two surfaces to mate smoothly together, we had to do additional adjustment to the bend at the area where the two surfaces meet, and by the end we got some pretty good results.

Then we attached the elevator to the horizontal stabilizer, we had to adjust the number of rotations of the bearing to get good range of motion.  We have now bigger than the max 30deg range of motion, which we can reduce later on. We also had to remove a little bit of material from the horizontal stabilizer to make room for the horns, to get the large range of motion.

The empennage is looking pretty good, time to move on to the wings.

Elevator Riveting and Trim Tab

December 8th and 9th 2018,11h

We finished the elevator skeleton riveting.

We riveted the elevator skeleton to the skin.  We missed putting RTV at the trailing edge where the stiffeners meet, which is because it was not specified in the instruction, but it is recommended by Van.  I checked with Van and they said that it is ok to proceed and that the elevator is air worthy without the RTV.

We still need to do few rivets that can not be reached with the pneumatic or back riveting, I am ordering some more flash pop rivets for those.

  • Match drilling
  • Deburing
  • Dimpling
