Bret, did you drill out/off the skin at the rear spar?? Mark, how did you buck the fish mouth area rivets?? Difficult? easy?? How much time? Right hand-left hand-blind rivets???
If you plan on selling your airplane, how will you answer the "Stab Spar Mod" question. (no mod? subtract $2000).
Thanks

Ed,
I think we've all been too busy installing the kit!
The hardest part is drilling/punching out those rivets on the ends of the angles.
I used an angle drill.
The riveting turned out to be a "non-issue" for me.
Up in the tight spots I used a 3X gun with a short (3") offset rivet set.
Take the spring off the gun, there's no room for it.
Turn the rivet set for each rivet to line it up with the gun in an optimum position to hold well. Tape the rivet set to the gun with electrical tape to keep it from rotating while riveting.
Nearly every rivet requires a repositioning of the set and tape it again.
I ran the air pressure on 60 but I'm sure some 3X guns are different.
It is quite a project. More than the few evenings I had estimated. I just reinstalled the empennage back on my 7A tonight.
I plan to fly tomorrow, it's been a long time!
As to how will I answer the "Stab Spar Mod" question. I will simply tell the truth. That I had two cracks and complied with the SB by installing the Vans kit.
Good luck with yours. Just take it slow and easy on the ones that are hard to get to.
Mark
