Hi all,
Resolved issue with getting the upside down bolt into the upper strut fitting after having rivetted the trailing edge of the nose skin on and the angle and doubler that supports the upper strut fitting. As of my last post I was going to send and email to Caleb at Zenith. Unfortunately he did not have any advice on how to resolve the problem. However, a friend who works for a company here in Vacouver that rebuilds jet engines for the USAF and commercial airlines, and had dropped by for a coffee on Sat morning did. To get the bolt in we removed 5 rivets outboard of rib #4 and 4 inboard, along the spar, as well as the angle that holds the doubler. Maybe 25 rivets. That left enough slack (for lack of a better term) in the nose skin to lift it and get the bolt in. touched up the zinc chromate and I’m ready to put the rivets back in.
The method I used for removing the rivets was drill off the head with #30 drill (same as for original hole) and then pop the rivet out with a Starrett automatic punch. Taking the rivets out is as easy as putting them in. No damage to skin or hole.
Regards,
Perry
