Brief Description: Finished bucking remaining rivets on the HS skin.
We continued with bucking the rivets on the other HS stabilizer and used blind rivets to attach some of the internal ribs where no bucking access existed. We only had to drill out a single rivet and decided to use an ‘oops’ rivet near the leading edge where an existing hole was found to be slightly elongated. We found we tended to under set a lot of the 426AD3-3.5. Most likely due to the fact I tended to use slightly shorter rivet gun duration then required. We had to come back and tap a bunch to the final size. During one line of rivets they were all clearly under set, but this was the result of our line pressure decreasing at some point. From then on we checked to ensure the pressure gauge was indicating sufficient pressure and we increased our duration for all subsequent rivets.
Up next is to squeeze all the edge rivets then set the final blind rivets in the rear spar.
Sean Holland helpful as always
Top side bucked rivets are done
Only the edge rivets are left for the hand squeezer
