Fuselage - Forward Section
Today, I discovered a little problem with dimpling the holes in the AFT section just behind the F-706 bulkhead. The bulkhead is way too wide to be able to get a squeezer in there. So what did I do? Read on.
|We're back to the AFT Fuselage, by itself. Now, we can take care a few of our mistakes.|
|Like this one.|
|And this one. Yep, these rivets were installed when I riveted the AFT Fuselage before attaching the Center Section. So, I just drilled right through them when I match-drilled the Center Section to the AFT Fuselage. Now, we can fix them.|
|Ok, here is the problem with the holes behind the F-706 bulkhead.|
|This was my solution. I drilled a hole in the end of a large closet hanger dowel and inserted the female dimple die. I used a few blocks under the dowel to fit up against the bottom of the AFT fuselage.|
|Then, I could dimple the holes with the C-Frame rod. Wait a second, C-frame rod, hmmm... What if I turned the fuselage right side up.|
| Yep, that works, also. The C-frame just barely cleared the F-706 bulkhead. I had to use a very low profile male dimple punch, but it worked. |
So, am I proud of this brilliant idea to turn the fuselage right-side-up and dimple these holes? No, that should have been obvious. The point is that whatever the problem is, there is always a solution. Some solutions are better than others, but there is always a way. The coat hanger dowel worked. It was a solution. There just happened to be a better one.
|Fortunately, all of the rivets on the side can be reached with the squeezer by pulling back the side skins.|
|AFT Fuselage, deburred and dimpled. Now, we can take care of countersinking those long erons.|
