Brief Description: New New HS Forward Spar Match Drilling
|
|
I toyed around with the idea that I could somehow crawl back to the rear fuse inside the airframe, I removed everything inside that was removable, and laid the original access board down inside the fuse - but I realized quickly there is no way I was going to be able to crawl back to the rear fuse to match drill the HS.
Removed the rear bulkhead by drilling out the blind rivets to open access to the rear fuse.
I made a cardboard stand for the iPad, at ~ 45-degree angle, then put the iPad in selfie mode, and placed inside the airframe pointed towards the existing #19 holes for the AN3 bolts attaching the HS to the aft deck. This gave me a fixed big screen view of how to match drill.
After securing the HS in place, used the angle drill to match drill from the inside of the fuse to the HS. First used a #40, then #30, then #19. Took my time and all four holes came out clean.
WHEW!!!
