Brief Description: Rib Riveting of the Vertical Stab
- Attached the rib and spar assemblies with the rivets per the instructions but it appeared the 470 4-4 rivets were too short for the middle Nose Rib and Inspar Rib in that the shop head looked a little flat after squeezing to the proper diameter. In retrospect it was probably ok but I drilled them out and replaced them with 470 4-4.5s which fit properly (I should have checked length before squeezing). I found the same rivet length problem with the bottom Nose and Inspar Rib rivets as well and used the same half-size bigger rivets when these pieces were assembled later during skin riveting.
