Continued working on the aft fuse today. When I dimpled the F-711 I discovered that there wasn't enough room to get a dimple die in between the flange and the bars at the upper side. I suspect that I could have bent the flange, dimpled, and then bent it back, but I spent a lot of time getting the angles right on those bulkheads.

I broke out a specialty tool that I got from Cleaveland a while back. Basically it's a low profile female die built into a steel strap that you can screw down to a table top. I put a male die into a junk socket and whacked it with a hammer. worked fine.

There were a couple of places where I had oversized the prepunched hole in the bulkhead flanges, and I went with an industry standard fix. a dimpled "washer" to back it up.

The WD-409 fit perfectly with the shims I had previously fabricated.

At this point, It's all back together and ready to start riveting
